54 * Version 3.1.2 (released 2012-09-26)
56 ** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
57 and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
58 of certificates in the windows platform.
60 ** libgnutls: Corrected bug in OpenPGP subpacket encoding.
62 ** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
63 (the work was done during Google Summer of Code).
65 ** libgnutls: Added X.509 certificate verification flag
66 GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
67 of unsorted certificate chains and is enabled by default for
68 TLS certificate verification (if gnutls_certificate_set_verify_flags()
69 does not override it).
71 ** libgnutls: Prints warning on certificates that contain keys of
72 an insecure level. If the %COMPAT priority flag is not specified
73 the TLS connection fails.
75 ** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
76 if interrupted during the retrasmition of handshake data.
78 ** libgnutls: Better mingw32 support (patch by LRN).
80 ** libgnutls: The %COMPAT keyword, if specified, will tolerate
81 key usage violation errors (they are far too common to ignore).
83 ** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
84 which provides a tool to counter compression-related attacks where
85 parts of the data are controlled by the attacker _and_ are placed in
86 separate records (use with care - do not use compression if not sure).
88 ** libgnutls: Depends on libtasn1 2.14 or later.
90 ** certtool: Prints the number of bits of the public key algorithm
91 parameter in a private key.
93 ** API and ABI modifications:
94 gnutls_x509_privkey_get_pk_algorithm2: Added
95 gnutls_heartbeat_ping: Added
96 gnutls_heartbeat_pong: Added
97 gnutls_heartbeat_allowed: Added
98 gnutls_heartbeat_enable: Added
99 gnutls_heartbeat_set_timeouts: Added

101 GNUTLS_SEC_PARAM_WEAK: Added
102 GNUTLS_SEC_PARAM_INSECURE: Added
104 * Version 3.1.1 (released 2012-09-02)
106 ** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
108 ** certtool: Changes in password handling of certtool.
109 Ask password when required and only if the '--password' option is not
110 given. If the '--password' option is given during key generation then
111 assume the PKCS #8 file format, instead of ignoring the password.
113 ** tpmtool: No longer asks for key password in registered keys.
115 ** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
116 wmNAF is now used for point multiplication and other optimizations.
117 (the major part of the work was done during Google Summer of Code).
119 ** libgnutls: The default pull_timeout_function only uses select
120 instead of a combination of select() and recv() to prevent issues
121 when used in stream sockets in some systems.
123 ** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
124 SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
127 ** libgnutls: Fixed DSA and ECDSA signature generation in smart
128 cards. Thanks to Andreas Schwier from cardcontact.de for providing
129 me with ECDSA capable smart cards.
131 ** API and ABI modifications:
132 gnutls_sign_algorithm_get: Added
133 gnutls_sign_get_hash_algorithm: Added
134 gnutls_sign_get_pk_algorithm: Added
137 * Version 3.1.0 (released 2012-08-15)
139 ** libgnutls: Added direct support for TPM as a cryptographic module
140 in gnutls/tpm.h. TPM keys can be used in functions accepting files
141 using URLs of the following types:
142 tpmkey:file=/path/to/file
143 tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
145 ** libgnutls: Priority string level keywords can be combined.
146 For example the string "SECURE256:+SUITEB128" is now allowed.
148 ** libgnutls: requires libnettle 2.5.
150 ** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
151 for encryption and signatures.
153 ** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
154 generic errors and signature verification errors in the verification
157 ** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
158 to simplify parsing in most PKCS #12 use cases.
160 ** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
161 the whole certificate chain (if any) to the credentials structure, instead
162 of only the end-user certificate.
164 ** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
165 and gnutls_x509_privkey_import_pkcs8(), return consistently
166 GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
167 password was provided.
169 ** libgnutls: Added gnutls_handshake_set_timeout() a function that
170 allows to set the maximum time spent in a handshake.
172 ** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
175 ** tpmtool: Added. It is a tool to generate private keys in the
178 ** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
179 and --benchmark-tls-ciphers
181 ** certtool: generated PKCS #12 structures may hold more than one
182 private key. Patch by Lucas Fisher.
184 ** certtool: Added option --null-password to generate/decrypt keys
185 that use a NULL password (in schemas that distinguish between NULL

256 that prevented the loading of EC private keys when DER
257 encoded. Reported by David Woodhouse.
259 ** libgnutls: In DTLS larger to mtu records result to
260 GNUTLS_E_LARGE_PACKET instead of being truncated.
262 ** libgnutls: gnutls_dtls_get_data_mtu() is more precise. Based
263 on patch by David Woodhouse.
265 ** libgnutls: Fixed memory leak in PKCS #8 key import.
267 ** libgnutls: Added support for an old version of the DTLS protocol
268 used by openconnect vpn client for compatibility with Cisco's AnyConnect
269 SSL VPN. It is marked as GNUTLS_DTLS0_9. Do not use it for newer protocols
272 ** libgnutls: Corrected bug that prevented resolving PKCS #11 URLs
273 if only the label is specified. Patch by David Woodhouse.

509 ** libgnutls: Added OCSP support.
510 There is a new header file gnutls/ocsp.h and a set of new functions
511 under the gnutls_ocsp namespace. Currently the functionality provided
512 is to parse and extract information from OCSP requests/responses, to
513 generate OCSP requests and to verify OCSP responses. See the manual
514 for more information. Run ./configure with --disable-ocsp to build
515 GnuTLS without OCSP support.
517 This work was sponsored by Smoothwall <http://smoothwall.net/>.

597 ** gnutls-cli: Fixed reading from windows terminals.
599 ** libgnutls: When GNUTLS_OPENPGP_FMT_BASE64 is specified
600 the stream is assumed to be base64 encoded (previously

624 it will only list the ciphersuites that are enabled by the given
627 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
628 changes the ciphersuite selection procedure. If specified the server
629 priorities will be used for selection instead of the client's.
631 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
634 ** libgnutls: When session tickets are negotiated and used in a
635 session, a server will not store that session data into its cache.

949 This uses more memory but eliminates issues with TLS 1.2 and
952 ** libgnutls: Added AES-GCM optimizations using the PCLMULQDQ
953 instruction. Uses Andy Polyakov's assembly code.
955 ** libgnutls: Added gnutls_x509_trust_list_add_named_crt() and

1246 ** libgnutls: The deprecated gnutls_x509_privkey_sign_hash() was
1247 replaced by gnutls_privkey_sign_hash2().
1249 ** libgnutls: gnutls_pubkey_verify_data, gnutls_pubkey_verify_hash,
1250 gnutls_x509_privkey_verify_data, gnutls_x509_crt_verify_data,
1251 gnutls_x509_crt_verify_hash return the negative error code
1252 GNUTLS_E_PK_SIG_VERIFY_FAILED if verification fails to simplify error
1255 ** libgnutls: Added helper functions for signature verification:
1256 gnutls_pubkey_verify_data() and gnutls_pubkey_import_privkey().
1258 ** libgnutls: Modified gnutls_privkey_sign_data().
1260 ** gnutls_x509_crl_privkey_sign2(), gnutls_x509_crq_sign2()
1261 gnutls_x509_privkey_sign_hash(), gnutls_x509_privkey_sign_data(),
1262 gnutls_x509_crt_verify_hash(), gnutls_x509_crt_verify_data(), were
1263 deprecated for gnutls_x509_crl_privkey_sign(),
1264 gnutls_x509_crq_privkey_sign(), gnutls_privkey_sign_hash(),
1265 gnutls_privkey_sign_data(), gnutls_pubkey_verify_hash()
1266 gnutls_pubkey_verify_data() respectively.
1268 ** libgnutls: gnutls_*_export_raw() functions now add leading zero in
1271 ** libgnutls: Added convenience functions gnutls_x509_crl_list_import2()
1272 and gnutls_x509_crt_list_import2().
1274 ** crypto.h: Fix use with C++.
1275 Reported by "Brendan Doherty" <brendand@gentrack.com>.

1304 * Version 2.11.6 (released 2010-12-06)
1306 ** libgnutls: Record version of Client Hellos is now set by default to
1307 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
1310 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
1311 This makes us comply with RFC3279. Reported by Michael Rommel.
1313 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
1315 ** API and ABI modifications:
1316 No changes since last version.
1318 * Version 2.11.5 (released 2010-12-01)
1320 ** libgnutls: Reverted default behavior for verification and
1321 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
1322 V1 trusted CAs are allowed, unless the new flag is specified.
1324 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
1325 Reported by Jeffrey Walton.
1327 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
1328 as priority strings. Those allow to set all the supported algorithms
1331 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
1333 ** gnutls-cli: Print channel binding only in verbose mode.
1334 Before it printed it after the 'Compression:' output, thus breaking
1335 Emacs starttls.el string searches.
1337 ** API and ABI modifications:
1338 gnutls_pkcs11_token_init: New function
1339 gnutls_pkcs11_token_set_pin: New function
1341 * Version 2.11.4 (released 2010-10-15)
1343 ** libgnutls: Add new API gnutls_session_channel_binding.
1344 The function is used to get the channel binding data. Currently only
1345 the "tls-unique" (RFC 5929) channel binding type is supported, through
1346 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
1349 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
1351 ** doc: Added pkcs11.h header file to GTK-DOC manual.
1353 ** build: Update gnulib files.
1355 ** i18n: Update translations.
1357 ** tests: Add self tests gendh.c. Speed up Guile self checks.
1359 ** API and ABI modifications:
1360 gnutls_session_channel_binding: New function.
1361 gnutls_channel_binding_t: New enumeration.
1362 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
1363 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
1365 * Version 2.11.3 (released 2010-10-14)
1367 ** Indent code to follow the GNU Coding Standard.
1368 You should be able to unpack the 2.11.2 release and run 'make indent'
1369 twice to get exactly the same content as 2.11.3 except for generated
1370 files. Using GNU Indent 2.2.11.
1372 ** API and ABI modifications:
1373 No changes since last version.
1375 * Version 2.11.2 (released 2010-10-08)
1377 ** libgnutls: Several bug fixes on session resumption
1378 and session tickets support.
1380 ** libgnutls: Add new extended key usage ipsecIKE.
1382 ** certtool: Renamed PKCS #11 options to: --p11-provider,
1383 --p11-export-url, --p11-list-certs, --p11-list-certs,
1384 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
1385 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
1386 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1389 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1390 introduced with the new nettle code.
1392 ** libgnutls: Corrected advertizing issue for session tickets.
1394 ** API and ABI modifications:
1395 gnutls_x509_crt_get_subject_unique_id: ADDED.
1396 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1398 * Version 2.11.1 (released 2010-09-14)
1400 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1401 to use the libgcrypt back end.
1403 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1404 backend crypto library.
1406 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1408 ** libgnutls: Several updates in the buffering internal interface.
1410 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1411 tabs are being skipped.
1413 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1415 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1418 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1419 system calls. Applications that depended on it being 1 should explicitly call
1420 gnutls_transport_set_lowat().
1422 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1423 to ECRYPT II recommendations. Mappings were moved to a single location
1424 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1425 and 3072 keys only).
1427 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1428 gnutls_x509_privkey_import_pkcs8() without a password, if it
1429 is unable to decode the key.
1431 ** libgnutls: HMAC-MD5 no longer used by default.
1433 ** API and ABI modifications:
1434 gnutls_openpgp_privkey_sec_param: ADDED
1435 gnutls_x509_privkey_sec_param: ADDED
1437 * Version 2.11.0 (released 2010-07-22)
1439 ** libgnutls: support scattered write using writev(). This takes
1440 advantage of the new buffering layer and allows queuing of packets
1441 and flushing them. This is currently used for handshake messages
1444 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1445 alternative locking procedures. By default the system available
1446 locking is used. In *NIX pthreads are used and in windows the
1447 critical section API. This follows a different approach than the
1448 previous versions that depended on libgcrypt initialization. The
1449 locks are now set by default in systems that support it. Programs
1450 that used gcry_control() to set thread locks should insert it into
1452 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1456 ** libgnutls: Added support for reading DN from EV-certificates.
1458 jurisdictionOfIncorporationLocalityName,
1459 jurisdictionOfIncorporationStateOrProvinceName,
1460 jurisdictionOfIncorporationCountryName
1462 ** libgnutls: Added support for DSA signing/verifying with bit
1465 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1466 has to be called to register any required md5 handlers.
1468 ** libgnutls: Internal buffering code was replaced by simpler
1469 code contributed by Jonathan Bastien-Filiatrault.
1471 ** libgnutls: Internal API for extensions augmented to allow
1472 safe storing and loading of data on resumption. This allows writing
1473 self-contained extensions (when possible). As a side effect
1474 the OPRFI extension was removed.
1476 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1478 ** libgnutls: Added PKCS #11 support and an API to access objects in
1479 gnutls/pkcs11.h. Currently certificates and public keys can be
1480 imported from tokens, and operations can be performed on private keys.
1482 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1484 ** libgnutls: Added initial support for the nettle library. It uses
1485 the system's random generator for seeding. That is /dev/urandom in Linux,
1486 system calls in Win32 and EGD on other systems.
1488 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1489 works even when resuming a session.
1491 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1492 similar gnutls_certificate_set_server_retrieve_function() and
1493 gnutls_certificate_set_client_retrieve_function(). In addition it support
1494 PKCS #11 private keys.
1496 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1497 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1499 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1500 sizes for private keys using a human understandable scale.
1502 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1503 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1504 --pkcs11-delete-url, --pkcs11-write
1506 certtool: The --pkcs-cipher is taken into account when generating a
1507 private key. The default cipher used now is aes-128. The old behavior can
1508 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1510 certtool: Added --certificate-pubkey to print the public key of the
1513 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1514 can now accept a PKCS #11 URL in addition to a file. This will allow for
1515 example to use the Gnome-keyring trusted certificate list to verify
1516 connections using a url such as:
1517 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1598 * Version 2.10.1 (released 2010-07-25)
1600 ** libgnutls: Added support for broken certificates that indicate RSA
1603 ** gnutls-cli: Allow verification using V1 CAs.
1605 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1606 gnutls_x509_privkey_import_pkcs8() without a password, if it
1607 is unable to decode the key.
1609 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1610 a memory leak. Reported by Mads Kiilerich.
1612 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1613 issue a warning, that the output key might not be working everywhere.
1615 ** certtool: The --pkcs-cipher is taken into account when generating a
1616 private key. The default cipher used now is aes-128. The old behavior
1617 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1619 ** API and ABI modifications:

1634 No changes since last version.
1636 * Version 2.9.11 (released 2010-06-07)
1638 ** libgnutls: Removed two APIs related to safe renegotiation.
1639 Use priority strings instead. The APIs were
1640 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1641 (Remember that we don't promise ABI stability during development
1642 series, so this doesn't cause an shared library ABI increment.)
1644 ** tests: More self testing of safe renegotiation extension.
1645 See tests/safe-renegotiation/README for more information.
1647 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1649 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1651 ** API and ABI modifications:
1652 gnutls_safe_negotiation_set_initial: REMOVED.
1653 gnutls_safe_renegotiation_set: REMOVED.
1655 * Version 2.9.10 (released 2010-04-22)
1657 ** libgnutls: Time verification extended to trusted certificate list.
1658 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1661 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1662 Based on patch by Pavan Konjarla. Adds new constant
1663 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1665 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1666 Solves the issue discussed in:
1667 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1668 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1669 Note that to allow connecting to unpatched servers the full protection
1670 is only enabled if the priority string %SAFE_RENEGOTIATION is
1671 specified. You can check whether protection is in place by querying
1672 gnutls_safe_renegotiation_status(). New error codes
1673 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1674 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1676 ** libgnutls: When checking openpgp self signature also check the signatures
1678 Ilari Liusvaara noticed and reported the issue and provided test
1681 ** libgnutls: Added cryptodev support (/dev/crypto).
1682 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1683 benchmark utility for AES. Adds new error codes
1684 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1686 ** libgnutls: Exported API to access encryption and hash algorithms.
1687 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1688 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1689 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1690 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1691 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1692 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1693 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1695 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1696 verification of certificate upon receipt rather than waiting until the
1697 end of the handshake.
1699 ** libgnutls: Don't send alerts during handshake.
1700 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1702 ** certtool: Corrected two issues that affected certificate request generation.
1703 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1704 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1705 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1706 those parameters there since other implementations don't do either and having
1707 them does not seem to offer anything (anyway you need the signer's certificate
1708 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1709 This however has the side-effect that public key IDs shown by certtool are
1710 now different than previous gnutls releases.
1711 (3) the option --pgp-certificate-info will verify self signatures
1713 ** certtool: Allow exporting of Certificate requests on DER format.
1715 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1717 ** gnutls-cli: Handle reading binary data from server.

1779 ** API and ABI modifications:
1780 No changes since last version.
1782 * Version 2.9.8 (released 2009-11-05)
1784 ** libgnutls: Fix for memory leaks on interrupted handshake.
1785 Reported by Tang Tong.
1787 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1788 ** extension and certificate verify field.
1789 This requires changes for TLS 1.2 servers and clients that use
1790 callbacks for certificate retrieval. They are now required to check
1791 with gnutls_sign_algorithm_get_requested() whether the certificate
1792 they send complies with the peer's preferences in signature
1795 ** libgnutls: In server side when resuming a session do not overwrite the
1796 ** initial session data with the resumed session data.
1798 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
1800 This affects also PKCS #12 encoded files. This adds the following new
1801 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
1802 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
1804 ** libgnutls: Fix PKCS#12 encoding.
1805 The error you would get was "The OID is not supported.". Problem
1806 introduced for the v2.8.x branch in 2.7.6.
1808 ** certtool: Added the --pkcs-cipher option.
1809 To explicitely specify the encryption algorithm to use.
1811 ** tests: Added "pkcs12_encode" self-test to check PKCS#12 functions.
1813 ** tests: Fix time bomb in chainverify self-test.

1847 ** libgnutls: Enable Camellia ciphers by default.
1849 ** API and ABI modifications:
1850 No changes since last version.
1852 * Version 2.9.5 (released 2009-09-10)
1854 ** libgnutls: Add new functions to extract X.509 Issuer Alternative Names.
1855 The new functions are gnutls_x509_crt_get_issuer_alt_name2,
1856 gnutls_x509_crt_get_issuer_alt_name, and
1857 gnutls_x509_crt_get_issuer_alt_othername_oid. Contributed by Brad
1858 Hards <bradh@frogmouth.net>.
1860 ** API and ABI modifications:

1867 ** libgnutls: Client-side TLS 1.2 and SHA-256 ciphersuites now works.
1868 The new supported ciphersuites are AES-128/256 in CBC mode with
1869 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1870 SHA-256 is now the preferred default MAC (however it is only used with
1873 ** libgnutls: Make OpenPGP hostname checking work again.
1874 The patch to resolve the X.509 CN/SAN issue accidentally broken
1875 OpenPGP hostname comparison.
1877 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1878 Reported by Howard Chu <hyc@symas.com> in
1879 <https://savannah.gnu.org/support/?106975>.
1881 ** Fix use of deprecated types internally.
1882 Use of deprecated types in GnuTLS from now on will lead to a compile
1883 error, to prevent this from happening again.
1885 ** API and ABI modifications:
1886 No changes since last version.
1888 * Version 2.9.3 (released 2009-08-19)
1890 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1891 The new APIs are gnutls_session_ticket_enable_client,
1892 gnutls_session_ticket_enable_server, and
1893 gnutls_session_ticket_key_generate.
1895 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

1900 gnutls_session_ticket_enable_server: ADDED.
1902 * Version 2.9.2 (released 2009-08-14)
1904 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1905 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1906 into 1) not printing the entire CN/SAN field value when printing a
1907 certificate and 2) cause incorrect positive matches when matching a
1908 hostname against a certificate. Some CAs apparently have poor
1909 checking of CN/SAN values and issue these (arguable invalid)
1910 certificates. Combined, this can be used by attackers to become a
1911 MITM on server-authenticated TLS sessions. The problem is mitigated
1912 since attackers needs to get one certificate per site they want to
1913 attack, and the attacker reveals his tracks by applying for a
1914 certificate at the CA. It does not apply to client authenticated TLS
1915 sessions. Research presented independently by Dan Kaminsky and Moxie
1916 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1917 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1919 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1920 The function may fail incorrectly when an earlier certificate was
1921 imported to the same gnutls_x509_crt_t structure.
1923 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1925 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1926 Before it always returned false. Reported by Peter Hendrickson
1927 <pdh@wiredyne.com> in
1928 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
1930 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
1931 The error resulted in truncated strings when printing unknown OIDs in
1932 X.509 certificate DNs. Reported by Tim Kosse
1933 <tim.kosse@filezilla-project.org> in
1934 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
1936 ** libgnutls: Fix PKCS#12 decryption from password.
1937 The encryption key derived from the password was incorrect for (on
1938 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1939 Tomas" <tomas.kukosa@siemens-enterprise.com> in
1940 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.
1942 ** libgnutls: Return correct bit lengths of some MPIs.
1943 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1944 gnutls_dh_get_peers_public_bits. Before the reported value was
1945 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
1946 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
1948 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.

1952 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
1954 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1955 Before we required that the runtime library used the same (or more
1956 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1957 that the runtime usage is above the minimum required. Reported by
1958 Marco d'Itri <md@linux.it> via Andreas Metzler
1959 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
1961 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
1963 ** tests: Improved test vectors in self-test pkcs12_s2k.
1965 ** tests: Added new self-test dn2 to detect off-by-one size error.

1996 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
1997 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1998 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
2000 Note: As a side effect of this change, the "public key identifier"
2001 value computed for a certificate using this version of GnuTLS will be
2002 different from values computed using earlier versions of GnuTLS.
2004 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
2005 ** optional SignatureAlgorithm parameter field.
2006 VeriSign rejected these CSRs. They are stricly speaking not needed
2007 since you need the signer's certificate to verify the certificate
2008 signature anyway. Reported by Wilankar Trupti

2132 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
2133 Before we required that the runtime library used the same (or more
2134 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
2135 that the runtime usage is above the minimum required. Reported by
2136 Marco d'Itri <md@linux.it> via Andreas Metzler
2137 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
2139 ** minitasn1: Internal copy updated to libtasn1 v2.3.

2150 <http://bugs.gentoo.org/272388>.
2152 ** libgnutls: Fix PKCS#12 decryption from password.
2153 The encryption key derived from the password was incorrect for (on
2154 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
2155 Tomas" <tomas.kukosa@siemens-enterprise.com> in

2267 *** API/ABI changes in GnuTLS 2.8 compared to GnuTLS 2.6.x
2268 No offically supported interfaces have been modified or removed. The
2269 library should be completely backwards compatible on both the source
2272 The shared library no longer exports some symbols that have never been
2273 officially supported, i.e., not mentioned in any of the header files.
2279 Normally when symbols are removed, the shared library version has to
2280 be incremented. This leads to a significant cost for everyone using
2281 the library. Because none of the above symbols have ever been
2282 intended for use by well-behaved applications, we decided that the it
2283 would be better for those applications to pay the price rather than
2284 incurring problems on the majority of applications.
2286 If it turns out that applications have been using unofficial
2287 interfaces, we will need to release a follow-on release on the v2.8
2288 branch to exports additional interfaces. However, initial testing
2289 suggests that few if any applications have been using any of the
2292 Although not a new change compared to 2.6.x, we'd like to remind you
2293 interfaces have been modified so that X.509 chain verification now
2294 also checks activation/expiration times on certificates. The affected
2297 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2298 gnutls_certificate_verify_peers: Likewise.
2299 gnutls_certificate_verify_peers2: Likewise.
2300 GNUTLS_CERT_NOT_ACTIVATED: ADDED.

2302 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2304 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2305 we gave our rationale for it in earlier release notes.
2307 The following symbols have been added to the library:

2460 ** API and ABI modifications:
2461 No changes since last version.
2463 * Version 2.7.8 (released 2009-05-03)
2465 ** libgnutls: Fix DSA key generation.
2466 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2468 ** libgnutls: Check expiration/activation time on untrusted certificates.
2469 Merged from stable branch. Reported by Romain Francoise
2470 <romain@orebokech.com>. This changes the semantics of
2471 gnutls_x509_crt_list_verify, which in turn is used by
2472 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2473 We add two new gnutls_certificate_status_t codes for reporting the new
2474 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2475 We also add a new gnutls_certificate_verify_flags flag,
2476 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2477 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2479 ** lib: Linker version scripts reduces number of exported symbols.
2480 The linker version script now lists all exported ABIs explicitly, to
2481 avoid accidentally exporting unintended functions. Compared to
2482 before, most symbols beginning with _gnutls* are no longer exported.
2483 These functions have never been intended for use by applications, and
2484 there were no prototypes for these function in the public header
2485 files. Thus we believe it is possible to do this without incrementing
2486 the library ABI version which normally has to be done when removing an
2489 ** lib: Limit exported symbols on systems without LD linker scripts.
2490 Before all symbols were exported. Now we limit the exported symbols
2491 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2492 _gnutls*. This is a superset of the actual supported ABI, but still
2493 an improvement compared to before. This is implemented using Libtool
2494 -export-symbols-regex. It is more portable than linker version
2497 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2498 This should have been done in the last release.
2500 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2501 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2502 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2504 ** doc: Improved sections for the info manual.
2505 We now follow the advice given by the texinfo manual on which
2506 directory categories to use. In particular, libgnutls moved from the
2507 'GNU Libraries' section to the 'Software libraries' and the command
2508 line tools moved from 'Network Applications' to 'System
2511 ** API and ABI modifications:
2512 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2513 gnutls_certificate_verify_peers: Likewise.

2517 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2519 * Version 2.7.7 (released 2009-04-20)
2521 ** libgnutls: Applied patch by Cedric Bail to add functions
2522 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2524 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.
2525 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
2526 <http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3467>.
2528 ** minitasn1: Internal copy updated to libtasn1 v1.8.
2529 GnuTLS is also internally ready to be used with libtasn1 v2.0.
2531 ** doc: Fix build failure of errcodes/printlist.
2532 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
2533 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
2535 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2536 It is currently only used by the core library. This will enable a new
2537 domain 'gnutls' for translations of the command line tools.
2539 ** Corrected possible memory corruption on signature verification failure.
2540 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2542 ** API and ABI modifications:
2543 gnutls_x509_crt_verify_hash: ADDED
2544 gnutls_x509_crt_get_verify_algorithm: ADDED
2546 * Version 2.7.6 (released 2009-02-27)
2548 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2549 This applies both to generating certificates and certificate requests.
2551 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2553 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2554 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2555 be used for chain verification.
2557 ** gnutls-serv: No longer disable MAC padding by default.
2558 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2560 ** gnutls-cli: Certificate information output format changed.
2561 The tool now uses libgnutls' functions to print certificate
2562 information. This avoids code duplication.
2564 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2565 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2566 They can be used to override the default certificate chain validation
2569 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2570 specify the client hello message record version. Used to overcome buggy
2571 TLS servers. Report by Martin von Gagern.
2573 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2575 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2577 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2579 ** API and ABI modifications:
2580 No changes since last version.
2582 * Version 2.7.5 (released 2009-02-06)
2584 ** libgnutls: Accept chains where intermediary certs are trusted.
2585 Before GnuTLS needed to validate the entire chain back to a
2586 self-signed certificate. GnuTLS will now stop looking when it has
2587 found an intermediary trusted certificate. The new behaviour is
2588 useful when chains, for example, contains a top-level CA, an
2589 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2590 To avoid chain validation errors due to the RSA-MD5 cert, you can
2591 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2592 The signature on trusted certificates are not checked, so the chain
2593 has a chance to validate correctly. Reported by "Douglas E. Engert"
2594 <deengert@anl.gov> in
2595 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2597 ** libgnutls: result_size in gnutls_hex_encode now holds
2598 the size of the result. Report by John Brooks <special@dereferenced.net>.
2600 ** libgnutls: gnutls_handshake when sending client hello during a
2601 rehandshake, will not offer a version number larger than the current.
2602 Reported by Tristan Hill <stan@saticed.me.uk>.
2604 ** libgnutls: Permit V1 Certificate Authorities properly.
2605 Before they were mistakenly rejected even though
2606 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2607 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2608 "Douglas E. Engert" <deengert@anl.gov> in

2614 * Version 2.7.4 (released 2009-01-07)
2616 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2617 This is a bugfix -- the previous attempt to do this from internal x509
2618 certificate verification procedures did not return the correct value
2619 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2620 <dkg@fifthhorseman.net> in
2621 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2622 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2623 Gillmor <dkg@fifthhorseman.net>.
2625 ** libgnutls: New interface to get key id for certificate requests.
2626 Patch from David Marín Carreño <davefx@gmail.com> in
2627 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2629 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2631 ** certtool: --verify-chain now prints results of using library verification.
2632 Earlier, certtool --verify-chain used its own validation algorithm
2633 which wasn't guaranteed to give the same result as the libgnutls
2634 internal validation algorithm. Now this command print a new final
2635 line with header 'Chain verification output:' that contains the result
2636 from using the internal verification algorithm on the same chain.
2638 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2640 ** API and ABI modifications:
2641 gnutls_x509_crq_get_key_id: ADDED.
2643 * Version 2.7.3 (released 2008-12-10)
2645 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2646 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
2647 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
2648 Andreas Metzler <ametzler@downhill.at.eu.org> in
2649 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2651 ** libgnutls: Libgcrypt initialization changed.
2652 If libgcrypt has not already been initialized, GnuTLS will now
2653 initialize libgcrypt with disabled secure memory. Initialize
2654 libgcrypt explicitly in your application if you want to enable secure
2655 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2656 allocation functions, which doesn't use secure memory, so there is no
2657 real change in behaviour.
2659 ** libgnutls: Fix memory leak in PSK authentication.
2660 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2661 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2663 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2665 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2666 It needs to be invoked before libgcrypt is initialized.
2668 ** gnutls-cli: Return non-zero exit code on error conditions.
2670 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2672 ** tests: Added chainverify self-test that tests X.509 chain verifications.
2674 ** API and ABI modifications:
2675 No changes since last version.
2677 * Version 2.7.2 (released 2008-11-18)
2679 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2680 The flaw makes it possible for man in the middle attackers (i.e.,
2681 active attackers) to assume any name and trick GnuTLS clients into
2682 trusting that name. Thanks for report and analysis from Martin von
2683 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2685 Any updates with more details about this vulnerability will be added
2686 to <http://www.gnu.org/software/gnutls/security.html>
2688 ** libgnutls: Fix namespace issue with version symbols.
2689 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
2690 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2691 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2692 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2693 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
2694 work but are deprecated.
2696 ** certtool: allow setting arbitrary key purpose object identifiers.
2698 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
2700 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2701 Reported by Kevin Quick <quick@sparq.org> in

2777 ** libgnutlsxx: Define server_session::get_srp_username even if no SRP.
2779 ** tests: Make tests compile when using internal libtasn1.
2780 Patch by ludo@gnu.org (Ludovic Courtès).
2782 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.

2812 * Version 2.6.6 (released 2009-04-30)
2814 ** libgnutls: Corrected double free on signature verification failure.
2815 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2816 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2818 ** libgnutls: Fix DSA key generation.
2819 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2820 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2821 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2823 ** libgnutls: Check expiration/activation time on untrusted certificates.
2824 Reported by Romain Francoise <romain@orebokech.com>. Before the
2825 library did not check activation/expiration times on certificates, and
2826 was documented as not doing so. We have realized that many
2827 applications that use libgnutls, including gnutls-cli, fail to perform
2828 proper checks. Implementing similar logic in all applications leads
2829 to code duplication. Hence, we decided to check whether the current
2830 time (as reported by the time function) is within the
2831 activation/expiration period of certificates when verifying untrusted
2834 This changes the semantics of gnutls_x509_crt_list_verify, which in
2835 turn is used by gnutls_certificate_verify_peers and
2836 gnutls_certificate_verify_peers2. We add two new
2837 gnutls_certificate_status_t codes for reporting the new error
2838 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2839 add a new gnutls_certificate_verify_flags flag,
2840 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2843 More details about the vulnerabilities will be posted at
2844 <http://www.gnu.org/software/gnutls/security.html>.
2846 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2847 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2848 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2850 ** tests: Fix linking of tests/openpgp/keyring self-test.
2851 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2853 ** API and ABI modifications:
2854 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2855 gnutls_certificate_verify_peers: Likewise.
2856 gnutls_certificate_verify_peers2: Likewise.
2857 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2858 GNUTLS_CERT_EXPIRED: ADDED.
2859 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2861 * Version 2.6.5 (released 2009-04-11)
2863 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2864 specify the client hello message record version. Used to overcome buggy
2865 TLS servers. Report by Martin von Gagern.
2867 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2868 Libtasn1 0.3.4 or later is required. This is to align with the
2869 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2871 ** API and ABI modifications:
2872 No changes since last version.
2874 * Version 2.6.4 (released 2009-02-06)
2876 ** libgnutls: Accept chains where intermediary certs are trusted.
2877 Before GnuTLS needed to validate the entire chain back to a
2878 self-signed certificate. GnuTLS will now stop looking when it has
2879 found an intermediary trusted certificate. The new behaviour is
2880 useful when chains, for example, contains a top-level CA, an
2881 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2882 To avoid chain validation errors due to the RSA-MD5 cert, you can
2883 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2884 The signature on trusted certificates are not checked, so the chain
2885 has a chance to validate correctly. Reported by "Douglas E. Engert"
2886 <deengert@anl.gov> in
2887 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2889 ** libgnutls: result_size in gnutls_hex_encode now holds
2890 the size of the result. Report by John Brooks <special@dereferenced.net>.
2892 ** libgnutls: gnutls_handshake when sending client hello during a
2893 rehandshake, will not offer a version number larger than the current.
2894 Reported by Tristan Hill <stan@saticed.me.uk>.
2896 ** libgnutls: Permit V1 Certificate Authorities properly.
2897 Before they were mistakenly rejected even though
2898 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2899 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2900 "Douglas E. Engert" <deengert@anl.gov> in
2901 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2903 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2904 This is a bugfix -- the previous attempt to do this from internal x509
2905 certificate verification procedures did not return the correct value

2943 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2944 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2945 problem for certificate chains that contained just one self-signed
2946 certificate. Reported by Michael Meskes <meskes@debian.org> in

2985 ** libgnutls: Correct printing and parsing of IPv6 addresses.
2987 ** libgnutls-openssl: fix out of bounds access.
2988 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2989 from Thomas Viehmann <tv@beamnet.de>.
2991 ** certtool: Use inet_pton for parsing IPv6 addresses.
2993 ** Major changes compared to the v2.4 branch:
2995 *** Added API to replace and update the crypto backend.
2997 *** certtool: can add several subject alternative names via template file.
2999 *** opencdk: Parse (but not decrypt) encrypted secret keys.
3001 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
3002 either set or append alternative names. It can also handle binary structures
3003 such as IP addresses.
3005 *** libgnutls: New function to set minimum acceptable SRP bits.
3006 The function is gnutls_srp_set_prime_bits.
3008 *** libgnutls: Add interface to deal with public key and signature algorithms.
3009 The functions are called gnutls_pk_list, gnutls_pk_get_id,
3010 gnutls_sign_list, and gnutls_sign_get_id.
3012 *** libgnutls: New interfaces to get name of public key and signing algorithms.
3013 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
3015 *** libgnutls: New API to get a string corresponding to a error symbol.
3016 The function is gnutls_strerror_name.
3018 *** libgnutls: New API to set the public parameters in a certificate request
3019 *** from a private key.
3020 The function is gnutls_x509_crq_set_key_rsa_raw.
3022 *** libgnutls: New API to set a callback to extract TLS Finished data.
3023 The function to register is gnutls_session_set_finished_function and
3024 it takes a callback of the gnutls_finished_callback_func type.
3026 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3028 *** libgnutls: New interface to register a new TLS extension handler.
3029 The new function gnutls_ext_register can be used to register handlers
3030 for specific TLS extension types. The callback functions have the new
3031 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3032 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3035 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
3036 The function is gnutls_register_md5_handler. When libgcrypt is in
3037 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
3040 *** API/ABI changes in GnuTLS 2.6
3041 No functions have been removed or modified. The library should be
3042 fully backwards compatible on both the source and binary level.
3044 A new header file <gnutls/crypto.h> have been added. It contains
3045 definitions related to replacing the internal crypto functionality.
3046 All definitions and the header itself is experimental but supported.
3048 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
3049 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
3050 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
3052 The following functions have been added to libgnutls:
3056 gnutls_crypto_bigint_register2

3092 Report and patch by Jonathan Manktelow.
3094 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
3095 The parameters are now allocated in the structure itself.
3097 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
3099 ** tests: Scripts now use EXEEXT properly.
3100 Modern libtool doesn't create wrapper script, so the self tests need
3101 to invoke certtool.exe under MinGW32+Wine.
3103 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
3104 Automake warnings are now also enabled.
3106 ** API and ABI modifications:
3107 gnutls_pk_params_st: MODIFIED
3109 * Version 2.5.8 (released 2008-09-21)
3111 ** certtool: updated so it can add several subject alternative names using
3114 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
3115 either set or append alternative names. It can also handle binary structures
3116 such as IP addresses.
3118 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
3120 ** libgnutls: New function to set minimum acceptable SRP bits.
3121 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
3122 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
3124 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.
3125 Also fix overflows in calls to those functions. Reported by Werner
3126 Koch <wk@gnupg.org>.
3128 ** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
3129 The function is gnutls_register_md5_handler. When libgcrypt is in
3130 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in

3141 gnutls_x509_crt_set_subject_alt_name: ADDED
3143 * Version 2.5.7 (released 2008-09-16)
3145 ** libgnutls: New interfaces to get name of public key and signing algorithms.
3146 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
3148 ** libgnutls: Don't crash when gnutls_credentials_set is called twice.
3150 ** libgnutls: Fix libgnutls shared library version.

3194 * Version 2.5.5 (released 2008-08-29)
3196 ** libgnutls: New API to get a string corresponding to a error symbol.
3197 The function is gnutls_strerror_name.
3199 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
3200 Reported by "jth.net ApS" <info@jth.net>.
3202 ** libgnutls: Fix segmentation fault when generating private keys.
3203 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3205 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
3206 The code has not worked since v0.9.0 and apparently nobody has missed
3207 it, so we decided to remove the code rather than fix it. If you have
3208 old certificate chains stored in PKCS#7 format, you can convert them
3209 to a list of PEM certificates by using 'certtool --p7-info'. Reported
3210 by Christian Grothoff <christian@grothoff.org>.
3212 ** opencdk: Parse (but not decrypt) encrypted secret keys.
3213 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.

3232 Added 'Since:' tags to new APIs for gtk-doc.
3234 ** API and ABI modifications:
3235 No changes since last version.
3237 * Version 2.5.3 (released 2008-08-14)
3239 ** libgnutls: New API to set the public parameters in a certificate request
3240 ** from a private key.
3241 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
3242 discussion with "Zach C." <fxchip@gmail.com>.
3244 ** libgnutls: New API to set a callback to extract TLS Finished data.
3245 The function to register is gnutls_session_set_finished_function and
3246 it takes a callback of the gnutls_finished_callback_func type.
3248 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
3249 Reported in <https://savannah.gnu.org/support/?106453>.
3251 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3252 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3253 names are mapped to the new names in compat.h. These mappings will
3254 likely be removed more quickly than other mappings in that file due to
3255 the namespace violation.
3257 ** libgnutlsxx: Make it build when SRP is disabled.
3259 ** doc: Add doxygen files in doc/doxygen/.
3261 ** API and ABI modifications:

3266 GNUTLS_RANDOM_SIZE: ADDED
3267 TLS_MASTER_SIZE: DEPRECATED
3268 TLS_RANDOM_SIZE: DEPRECATED
3270 * Version 2.5.2 (released 2008-07-08)
3272 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3273 The prime and generator was swapped.
3275 ** libgnutls: New interface to register a new TLS extension handler.
3276 The new function gnutls_ext_register can be used to register handlers
3277 for specific TLS extension types. The callback functions have the new
3278 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3279 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3282 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3283 This was made possible by using the new gnutls_ext_register interface.
3284 The TLS/IA functionality has only been supported through the
3285 libgnutls-extra library, so it makes sense for the code to belong

3289 gnutls_ext_recv_func: ADDED
3290 gnutls_ext_send_func: ADDED
3291 gnutls_ext_parse_type_t: ADDED
3292 gnutls_ext_register: ADDED
3294 * Version 2.5.1 (released 2008-07-02)
3298 ** API and ABI modifications:
3299 No changes since last version.
3301 * Version 2.5.0 (released 2008-07-02)
3303 ** Port fixes from v2.4.1 release, see below.
3305 ** Added API to replace and update the crypto backend.
3306 The header gnutls/crypto.h is now officially supported, and declares
3309 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3311 ** Update gnulib and translations.
3312 The gnulib gc crypto code has been removed since it was never finished
3313 and is no longer even used. An internal non-libgcrypt crypto
3314 implementation may be added in the future, but we'll decide that later

3319 gnutls_crypto_cipher_register2: ADDED.
3320 gnutls_crypto_digest_register2: ADDED.
3321 gnutls_crypto_mac_register2: ADDED.
3322 gnutls_crypto_pk_register2: ADDED.

3325 gnutls_crypto_single_digest_register2: ADDED.
3326 gnutls_crypto_single_mac_register2: ADDED.
3328 * Version 2.4.3 (released 2009-02-06)
3330 ** libgnutls: Accept chains where intermediary certs are trusted.
3331 Before GnuTLS needed to validate the entire chain back to a
3332 self-signed certificate. GnuTLS will now stop looking when it has
3333 found an intermediary trusted certificate. The new behaviour is
3334 useful when chains, for example, contains a top-level CA, an
3335 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3336 To avoid chain validation errors due to the RSA-MD5 cert, you can
3337 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3338 The signature on trusted certificates are not checked, so the chain
3339 has a chance to validate correctly. Reported by "Douglas E. Engert"
3340 <deengert@anl.gov> in
3341 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3343 ** libgnutls: Permit V1 Certificate Authorities properly.
3344 Before they were mistakenly rejected even though
3345 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3346 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3347 "Douglas E. Engert" <deengert@anl.gov> in
3348 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3350 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3351 This is a bugfix -- the previous attempt to do this from internal x509
3352 certificate verification procedures did not return the correct value
3353 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3354 <dkg@fifthhorseman.net> in
3355 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

3437 ** API and ABI modifications:
3438 No changes since last version.
3440 * Version 2.4.0 (released 2008-06-19)
3442 ** Major changes compared to the v2.2 branch:
3444 *** The OpenPGP sub-system has been improved and now supports subkeys.
3446 *** The PSK sub-system has been improved and now supports password
3447 *** derivation and PSK identity hints.
3448 The password derivation algorithms support is documented in
3449 draft-ietf-netconf-tls-02.txt.
3451 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3452 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3453 The old parameters will continue to work for some time.
3455 *** Certtool now confirm passwords and changes permissions of private key files.
3457 *** The default handshake size limit has been increased to 48kb.
3458 It appears as if some valid handshakes are large due to sending many
3459 CA certificates. (The earlier limit was 16kb.)
3461 *** LZO compression is now disabled by default.
3462 The main reason is that LZO compression in TLS is not standardized,
3463 but license compatiblity issues with minilzo triggered us to make this
3466 *** Improvements for cross-compilation to Windows and OpenWRT.
3468 *** The look of the GTK-DOC manual has been improved.
3469 Major developer visible changes compared to the v2.2 branch:
3471 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3473 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3474 *** elements from the certificate credentials structure.
3475 Thanks to Joe Orton.
3477 *** New APIs to improve working with username/passwords and PSK.
3479 *** Names of constants to affect certificate printing changed.
3480 The constants are used for OpenPGP too, which the names didn't
3481 reflect, so the following name change has been made:
3484 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3485 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3486 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3488 The old names will be mapped to the new names for some time.
3490 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3491 *** gnutls_openpgp_privkey_get_key_id.
3492 A compatibility mapping exists to avoid breaking API backwards
3495 *** Replaced all uses of alloca with malloc and free.
3497 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3498 We have been unable to find a documented rationale for this practice.
3500 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3502 *** API/ABI changes in GnuTLS 2.4
3503 All OpenPGP related functions have been moved from libgnutls-extra to
3504 libgnutls, and several new functions have been added (see below).
3505 Before making the release, we discussed whether moving functions from
3506 libgnutls-extra to libgnutls would require us to increment the ABI
3507 version, but the general opinion was that this would not be required.
3508 All older functions continue to work the same. We are open to the
3509 possibility that this decision will lead to problem on some platform,
3510 and if it turns out that the Right Thing should have been to increment
3511 the shared library version, we would need to release an update within
3512 the 2.4.x branch that increments the shared library version.
3514 This release adds the following functions:
3516 gnutls_psk_client_get_hint
3517 gnutls_psk_set_server_credentials_hint
3518 gnutls_psk_netconf_derive_key
3520 Used to get/set the PSK identity hint, and derive PSK keys from
3521 passwords a'la netconf.
3523 gnutls_x509_dn_deinit
3524 gnutls_x509_dn_export
3525 gnutls_x509_dn_import
3528 Used to handle X.509 Certificate DN's directly.
3532 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3535 gnutls_certificate_get_x509_cas
3536 gnutls_certificate_get_x509_crls
3537 gnutls_certificate_get_openpgp_keyring
3539 Functions for direct access to credential elements.

3582 New OpenPGP related functions.
3584 The function gnutls_openpgp_crt_get_key_id is the same as the old
3585 from gnutls_openpgp_crt_get_id, see above.
3587 The release also adds a new header file 'gnutls/crypto.h', however it
3588 is currently not used.

3605 * Version 2.3.14 (released 2008-06-11)
3607 ** libgnutls [OpenPGP]: Changed OpenPGP verification behaviour.
3608 An OpenPGP certificate is now only considered verified if all the user
3611 ** Examples: Make C++ example compile.
3612 Earlier it may have failed with an unresolved reference to strlen.
3614 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
3615 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
3617 ** API and ABI modifications:
3618 No changes since last version.
3620 * Version 2.3.13 (released 2008-06-07)
3622 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3624 ** doc/: Add psktool to info index. Some minor cleanups.
3626 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3628 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3629 The file suppresses the known libgcrypt memory leaks, so they aren't
3630 printed when you run valgrind on the gnutls self-tests. Use it as
3631 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
3632 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
3635 ** tests/: Reduce amount of debugging output by default.
3636 Use --verbose for each test to get the full output.
3638 ** tests/: Fix memory leaks in several self-tests.
3639 None of the self tests should be leaking memory when running valgrind
3640 or similar tools. (Known exceptions are dhepskself, pskself, and
3641 set_pkcs12_cred, which appear likely to be due to memory leaks in the
3644 ** API and ABI modifications:
3645 No changes since last version.
3647 * Version 2.3.12 (released 2008-06-04)
3649 ** Merge gnutls_with_netconf branch.
3651 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
3652 The function is gnutls_psk_client_get_hint.
3654 *** libgnutls [PSK]: New API to set PSK identity hint in server.
3655 The function is gnutls_psk_set_server_credentials_hint.
3657 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3658 In the client, the message is parsed and the application can use
3659 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3660 message is sent if the application has specified a PSK identity hint
3661 using gnutls_psk_set_server_credentials_hint.
3663 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3664 The function gnutls_psk_netconf_derive_key supports the PSK key
3665 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3668 *** psktool: Support new --netconf-hint to generate PSK key from password.
3669 Uses the Netconf algorithm to derive PSK key from password.
3671 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3673 *** gnutls-cli: Always support PSK modes, through a callback.
3674 The callback will derive a PSK key using Netconf algorithm. It will
3675 print the PSK identity hint to help the user.
3677 *** New PSK example client and server.
3678 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3680 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3681 The code didn't work properly on platforms where 'char' is unsigned,
3682 when you set version 0. Reported by Laurence Withers
3683 <l@lwithers.me.uk> in
3684 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
3686 ** libgnutls-openssl: added RAND_pseudo_bytes API.
3687 Patch from Robert Millan <rmh@aybabtu.com>.
3689 ** API and ABI modifications:
3690 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
3691 gnutls_psk_client_get_hint: ADDED.
3692 gnutls_psk_set_server_credentials_hint: ADDED.
3693 gnutls_psk_netconf_derive_key: ADDED
3695 * Version 2.3.11 (released 2008-05-20)
3697 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3698 The flaw would result in incorrectly terminated sessions with the
3699 error "Decryption has failed" when the server sends a small packet
3700 (typically when the session is closed). Reported by Andreas Metzler
3701 <ametzler@downhill.at.eu.org> in
3702 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3704 ** Don't use gnulib headers when building C++ library.
3705 Fixes builds under Windows.
3707 ** Make umask a requirement.
3708 We don't know of any system that lacks it, even GNU CoreUtils use it
3711 ** Update gnulib files.
3712 Fixes a problem where it pulled in a replacement for memcmp under
3713 MinGW, which caused the C++ example to fail to build.
3715 ** API and ABI modifications:
3716 No changes since last version.
3718 * Version 2.3.10 (released 2008-05-19)
3720 ** Added wide wildcard hostname matching.
3721 Tiny patch by Jean-Philippe Garcia Ballester.
3723 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3724 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3725 which allowed the bugs to be reproduced and fixed easily. Patches
3726 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3727 with more details about these vulnerabilities will be added to
3728 <http://www.gnu.org/software/gnutls/security.html>
3730 *** [GNUTLS-SA-2008-1-1]
3731 *** libgnutls: Fix crash when sending invalid server name.
3732 The crash can be triggered remotely before authentication, which can
3733 lead to a Daniel of Service attack to disable the server. The bug
3734 cause gnutls to store more session resumption data than what was
3735 allocated for, thus overwriting unallocated memory.
3737 *** [GNUTLS-SA-2008-1-2]
3738 *** libgnutls: Fix crash when sending repeated client hellos.
3739 The crash can be triggered remotely before authentication, which can
3740 lead to a Daniel of Service attack to disable the server. The bug
3741 triggers a null-pointer dereference.
3743 *** [GNUTLS-SA-2008-1-3]
3744 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3745 The crash can be triggered remotely before authentication, which can
3746 lead to a Daniel of Service attack to disable the server. The bug
3747 cause gnutls to read memory beyond the end of the received record.
3749 ** libgnutlsxx: Updated API according to patches from Eduardo
3750 Villanueva Che (discussion at
3751 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3753 ** Use umask to restrict permissions to owner before creating a file.
3755 ** API and ABI modifications:
3756 No changes since last version.
3758 * Version 2.3.9 (released 2008-05-16)
3760 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3761 Based on report and tiny patches from
3762 <jared.jennings.ctr@eglin.af.mil>, see
3763 <https://savannah.gnu.org/support/index.php?106342>.
3765 ** libgnutls: Translation fixes.
3767 ** gnutls-cli: Fix so that PSK authentication works.
3768 Also improve manual to give example for gnutls-cli PSK authentication.
3770 ** certtool: Encrypting a private key now require a confirmed password.
3771 Before './certtool -k -8' would merely ask for a password once.
3772 Reported by Daniel 'NebuchadnezzaR' Dehennin
3773 <nebuchadnezzar@asgardr.info> see
3774 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3776 ** certtool: When writing private keys to files, change permissions of file.
3777 Now the file which the private key is saved to is chmod'ed 0600.
3778 Reported by martin f krafft <madduck@debian.org> see
3779 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3781 ** guile: Fix -fgnu89-inline test.
3783 ** Removed --enable-profile-mode.
3784 The code linked gnutls with the libfc project (Function Check) which
3785 appears to have been stalled since around 2002.
3787 ** Clean up header file checks by ./configure.
3789 ** Update of gnulib files.
3791 ** API and ABI modifications:
3792 No changes since last version.
3794 * Version 2.3.8 (released 2008-04-29)
3796 ** libgnutls: Increase default handshake packet size limit to 48kb.
3797 The old limit was 16kb and some servers send huge list of trusted CAs,
3798 thus running into the limit. FYI, applications can further increase
3799 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3800 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3801 <marc@mclemente.net> for reporting and providing test servers.
3803 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3804 Returned when the handshake data size is too large. Before
3805 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3808 ** libgnutls: Hide definitions in crypto.h.
3809 We have decided that the APIs defined in crypto.h are not stable
3810 enough for v2.4, so don't use any of those functions.
3812 ** gnutls-cli: exit when hostname doesn't match certificate.
3813 Use --insecure to avoid hostname comparison.
3815 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3816 The reason is to align terminology with OpenPGP, which doesn't use
3817 DER. The old parameters will continue to work for some time.
3819 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3821 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3823 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3824 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3825 vasprintf symbol from the libgcrypt library which caused problems.
3827 ** Update of gnulib files.
3829 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3831 ** API and ABI modifications:
3832 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3834 * Version 2.3.7 (released 2008-04-21)
3836 ** opencdk now properly sets the key usage bits into openpgp keys.
3838 ** gnutls-cli: Fix crash on TLS handshake failures.
3839 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3840 This is similar to <http://bugs.debian.org/429183>.
3842 ** certtool: with --generate-request and newly generated keys, print the key.
3844 ** Build fixes for MinGW.
3845 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3846 with -lws2_32 when needed. Use ASCII only isprint() when printing
3847 X.509 certificate information, to avoid non-ASCII but printable
3848 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3851 ** Update internal copy of libtasn1 to version 1.4.
3853 ** API and ABI modifications:
3854 No changes since last version.
3856 * Version 2.3.6 (released 2008-04-17)
3858 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3859 ** Improve documentation for gnutls_x509_crq_sign2.
3860 Based on report from "John Brooks" <aspecialj@gmail.com> in
3861 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3863 ** tests/pathlen: run diff without parameters to improve portability.
3864 Based on HPUX build hints in
3865 <http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text>.
3867 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3868 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3869 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3871 ** Remove all uses of gnutls_alloca/gnutls_afree.
3872 Use normal gnutls_malloc instead. One reason is increased portability
3873 to Windows, the other is that several of the uses may be unsafe
3874 because the size of data allocated could be large. Reported by
3875 Massimo Gaspari <massimo.gaspari@alice.it> in
3876 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3878 ** Build Guile code with -fgnu89-inline only when supported.
3879 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3880 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3882 ** Several GTK-DOC related fixes.
3884 ** Clean up OpenCDK related code.
3885 GnuTLS now requires its internal OpenCDK code rather than the external
3886 GPL library OpenCDK. Unfortunately, we don't have resources to
3887 maintain an external library (help welcome).
3889 ** API and ABI modifications:
3890 No changes since last version.
3892 * Version 2.3.5 (released 2008-04-14)
3894 ** Build fix for MinGW and --disable-shared.
3895 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3896 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3898 ** Document how to generate CRLs.
3899 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3901 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3903 ** Several minor fixes in the OpenPGP interface.
3904 Thanks to Daniel Kahn Gillmor.
3906 ** Fix fopen file descriptor leak in PSK server code.
3907 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3908 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3910 ** Translations files not stored directly in git to avoid merge conflicts.
3912 ** New APIs to let applications replace the RNG used.
3913 Update all RNG callers in the code to use the new interface.
3915 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3917 ** Update gnulib files.
3919 ** API and ABI modifications:
3920 gnutls_crypto_rnd_register: ADDED
3921 gnutls_rnd_level_t: ADDED
3922 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3923 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3924 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3925 gnutls_crypto_rnd_st: ADDED
3926 GNUTLS_DIG_SHA224: ADDED
3927 GNUTLS_SIGN_RSA_SHA224: ADDED
3928 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3930 * Version 2.3.4 (released 2008-03-19)
3932 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3933 They weren't renamed in the public header file.
3935 ** Added functions to register a cipher/mac/digest. This allows to
3936 override the included ones.
3938 ** Fix a bunch of compiler warnings.
3940 ** API and ABI modifications:
3941 gnutls_crypto_cipher_st: ADDED
3942 gnutls_crypto_mac_st: ADDED
3943 gnutls_crypto_digest_st: ADDED
3944 gnutls_crypto_cipher_register: ADDED
3945 gnutls_crypto_mac_register: ADDED
3946 gnutls_crypto_digest_register: ADDED
3947 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3949 * Version 2.3.3 (released 2008-03-10)
3951 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3952 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3954 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3955 We could not find any modern justification for enabling these flags by
3956 default. If you know of some platform that needs one of the flags to
3957 work properly, please let us know. (Actually introduced in v2.3.0 but
3958 not documented until now.)
3960 ** Importing many CA certificates are now considerably faster.
3961 This affect gnutls_certificate_set_x509_trust_mem,
3962 gnutls_certificate_set_x509_trust, and
3963 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3964 from O(2*n^2) to O(n). When adding 206 files containing 408
3965 certificates, using gnutls_certificate_set_x509_trust_file, the time
3966 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3967 to trigger the problem. See also
3968 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3970 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3971 ** to be explicit that it takes zero terminated data.
3973 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3975 ** Documentation fixes for the GTK-DOC manual.
3977 ** Fix compilation error related to __FUNCTION__ on some systems.
3978 Reported by Tim Mooney, see
3979 <https://savannah.gnu.org/support/?106267>.
3981 ** Updated translations.
3983 ** Update gnulib files.
3985 ** API and ABI modifications:
3986 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3987 and char* instead of void* for output buffer.
3989 * Version 2.3.2 (released 2008-02-26)
3991 ** Fix srcdir!=objdir failure in openpgpself test.
3993 ** Improved API documentation output from GTK-DOC.
3995 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3997 ** Renamed gnutls_certificate_export_x509_cas and friends.
3998 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
4000 ** Internal header files cleanup.
4002 ** API and ABI modifications:
4003 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
4004 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
4005 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
4006 gnutls_x509_dn_export: ADDED
4008 * Version 2.3.1 (released 2008-02-21)
4010 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
4011 The included copy of OpenCDK has been stripped down and re-licensed
4014 ** Cipher priority string handling now handle strings that starts with NULL.
4015 Thanks to Laurence Withers <l@lwithers.me.uk>.
4017 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
4019 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
4022 ** Increased the default certificate verification chain limits and allowed
4023 for checks without limitation.
4025 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
4026 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
4027 strings and return the proper size.
4029 ** Add section 'On Record Padding' to the manual.
4030 This collects all problems related to record padding with
4031 Nokia/Sony-Ericsson phones that we know about.
4033 ** Several improvements in the OpenPGP authentication.
4034 Now subkeys can be used for authentication, according to
4035 draft-mavrogiannopoulos-rfc5081bis-00.txt.
4037 ** certtool can print information on OpenPGP certificates and keys.
4039 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
4042 ** Added gnutls_certificate_export_x509_cas and other functions to
4043 export elements from the certificate credentials structure. Based on
4044 suggestion from Joe Orton.
4047 Clarify that srp_base64 is not the same as normal base64.
4049 ** Fix non-portable use of brace expansion in makefiles.
4051 ** API and ABI modifications:
4052 gnutls_certificate_export_x509_cas: ADDED
4053 gnutls_certificate_export_x509_crls: ADDED
4054 gnutls_certificate_export_openpgp_keyring: ADDED
4055 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
4056 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
4057 gnutls_openpgp_crt_get_revoked_status: ADDED
4058 gnutls_openpgp_crt_get_subkey_count: ADDED

4099 ** LZO compression is now disabled by default.
4100 The reason is that LZO compression is not standardized in TLS. If you
4101 wish to experiment with it, you will have to supply --with-lzo when
4102 invoking ./configure. The internal copy of minilzo is no longer
4103 included with GnuTLS, so you will need to install liblzo or liblzo2 on
4104 your system to have --with-lzo to be effective.
4106 ** More than one server name field is now sent to the server properly.
4107 Thanks to mark.phillips@virgin.net.
4109 ** Fixes the post_client_hello_function(). The extensions are now parsed
4110 in a callback friendly way.
4112 ** Fix for certificate selection in servers with certificate callbacks.
4114 ** Updated translations.
4116 ** Update gnulib files.
4118 ** API and ABI modifications:
4119 No changes since last version.
4121 * Version 2.2.5 (released 2008-05-19)
4123 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4124 The flaw would result in incorrectly terminated sessions with the
4125 error "Decryption has failed" when the server sends a small packet
4126 (typically when the session is closed). Reported by Andreas Metzler
4127 <ametzler@downhill.at.eu.org> in

4135 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
4136 Thanks to CERT-FI for finding the bugs and providing detailed reports,
4137 which allowed the bugs to be reproduced and fixed easily. Patches
4138 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
4139 with more details about these vulnerabilities will be added to

4142 *** [GNUTLS-SA-2008-1-1]
4143 *** libgnutls: Fix crash when sending invalid server name.
4144 The crash can be triggered remotely before authentication, which can
4145 lead to a Daniel of Service attack to disable the server. The bug
4146 cause gnutls to store more session resumption data than what was
4147 allocated for, thus overwriting unallocated memory.
4149 *** [GNUTLS-SA-2008-1-2]
4150 *** libgnutls: Fix crash when sending repeated client hellos.
4151 The crash can be triggered remotely before authentication, which can
4152 lead to a Daniel of Service attack to disable the server. The bug
4153 triggers a null-pointer dereference.
4155 *** [GNUTLS-SA-2008-1-3]
4156 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
4157 The crash can be triggered remotely before authentication, which can
4158 lead to a Daniel of Service attack to disable the server. The bug
4159 cause gnutls to read memory beyond the end of the received record.
4161 ** API and ABI modifications:
4162 No changes since last version.
4164 * Version 2.2.3 (released 2008-05-06)
4166 ** Increase default handshake packet size limit to 48kb.
4167 The old limit was 16kb and some servers send huge list of trusted CAs,
4168 thus running into the limit. FYI, applications can further increase
4169 this limit using gnutls_handshake_set_max_packet_length. Thanks to
4170 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
4171 <marc@mclemente.net> for reporting and providing test servers.
4173 ** Fix compilation error related to __FUNCTION__ on some systems.
4174 Reported by Tim Mooney, see
4175 <https://savannah.gnu.org/support/?106267>.
4177 ** Documented the --priority option to gnutls-cli and gnutls-serv.
4179 ** Fix fopen file descriptor leak in PSK server code.

4191 ** API and ABI modifications:
4192 No changes since last version.
4194 * Version 2.2.2 (released 2008-02-21)
4196 ** Cipher priority string handling now handle strings that starts with NULL.
4197 Thanks to Laurence Withers <l@lwithers.me.uk>.
4199 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
4202 ** Increased the default certificate verification chain limits and allowed
4203 for checks without limitation.
4205 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
4206 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
4207 strings and return the proper size.
4209 ** API and ABI modifications:
4210 No changes since last version.
4212 * Version 2.2.1 (released 2008-01-17)
4214 ** Prevent linking libextra against previously installed libgnutls.
4215 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
4216 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
4218 ** Fixes the post_client_hello_function(). The extensions are now parsed
4219 in a callback friendly way.
4221 ** Fix for certificate selection in servers with certificate callbacks.
4223 ** API and ABI modifications:
4224 No changes since last version.
4226 * Version 2.2.0 (released 2007-12-14)
4228 ** Update internal copy of libtasn1 to version 1.2.
4230 ** Certtool --verify-chain now handle inputs larger than 64kb.
4231 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
4232 recent versions of libgcrypt. The problem was that Wine with the
4233 libgcrypt RNG generates huge amounts of debugging output.
4235 ** Translation updates.
4236 Added Dutch translation. Updated Polish and Swedish translation.
4238 ** Major changes compared to the v2.0 branch:
4240 *** SRP support aligned with newly published RFC 5054.
4242 *** OpenPGP support aligned with newly published RFC 5081.
4244 *** Support for DSA2 keys.
4246 *** Support for Camellia cipher.
4248 *** Support for Opaque PRF Input extension.
4250 *** PKCS#8 parser now handle DSA keys.
4252 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4253 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4254 versions, such as 2.01 which is included with GnuTLS, is available
4255 under GPLv2 or later. If this incompatibility causes problems, we
4256 recommend you to disable LZO using --without-lzo. LZO compression is
4257 not a standard TLS compression algorithm, so the impact should be
4260 *** Functions for disabling record protocol padding.
4261 Works around bugs on Nokia/Ericsson phones.
4263 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4264 Priorities like "COMPAT" also enables other work arounds, such as
4267 *** Other minor improvements and bug fixes.
4269 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4270 To adapt to changes in the TLS extension specifications for OpenPGP
4271 and SRP, the GnuTLS API had to be modified. This means breaking the
4272 API and ABI backwards compatibility. That is something we try to
4273 avoid unless it is necessary. We decided to also remove the already
4274 deprecated stub functions for X.509 to XML conversion and TLS
4275 authorization (see below) when we had the opportunity.
4277 Generally, most applications does not need to be modified. Just
4278 re-compile them against the latest GnuTLS release, and it should work
4281 Applications that use the OpenPGP or SRP features needs to be
4282 modified. Below is a list of the modified APIs and discussion of what
4283 the minimal things you need to modify in your application to make it
4284 work with GnuTLS 2.2.
4286 Note that GnuTLS 2.2 also introduces new APIs -- such as
4287 gnutls_set_priority() that is superior to
4288 gnutls_set_default_priority() -- that you may want to start using.
4289 However, using those new APIs is not required to use GnuTLS 2.2 since
4290 the old functions continue are still supported. This text only
4291 discuss what you minimally have to modify.
4293 *** XML related changes
4294 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4295 deprecated and only returned an error code since GnuTLS version
4296 1.2.11. Nobody has complained, so users doesn't seem to miss the
4297 functionality. We don't know of any other library to convert X.509
4298 certificates into XML format, but we decided (long ago) that GnuTLS
4299 isn't the right place for this kind of functionality. If you want
4300 help to find some other library to use here, please explain and
4301 discuss your use case on help-gnutls@gnu.org.
4303 *** TLS Authorization related changes
4304 Everything related to TLS authorizations have been removed, they were
4305 only stub functions that returned an error code:
4307 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4308 gnutls_authz_data_format_type_t
4309 gnutls_authz_recv_callback_func
4310 gnutls_authz_send_callback_func
4312 gnutls_authz_send_x509_attr_cert
4313 gnutls_authz_send_saml_assertion
4314 gnutls_authz_send_x509_attr_cert_url
4315 gnutls_authz_send_saml_assertion_url
4317 *** SRP related changes
4318 The callback gnutls_srp_client_credentials_function has a new
4319 prototype, and its semantic has changed. You need to rewrite the
4320 callback, see the updated function documentation and SRP example code
4321 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4324 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4325 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4326 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4327 used. There are #define's to map the old names to the new. You may
4328 run into problems if you have a switch-case with cases for both SRP
4329 alerts, since they are now mapped to the same value. The solution is
4330 to drop the SRP alerts from such switch cases, as they are now
4331 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4333 *** OpenPGP related changes
4334 The function `gnutls_certificate_set_openpgp_keyserver' have been
4335 removed. There is no replacement functionality inside GnuTLS. If you
4336 need keyserver functionality, consider using the GnuPG tools.
4338 All functions, types, and error codes related to OpenPGP trustdb
4339 format have been removed. The trustdb format is a non-standard
4340 GnuPG-specific format, and we recommend you to use key rings instead.
4341 The following have been removed:
4343 gnutls_certificate_set_openpgp_trustdb
4344 gnutls_openpgp_trustdb_init
4345 gnutls_openpgp_trustdb_deinit
4346 gnutls_openpgp_trustdb_import
4347 gnutls_openpgp_key_verify_trustdb
4348 gnutls_openpgp_trustdb_t
4349 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
4351 The following functions has an added parameter of the (new) type
4352 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4353 (binary or base64). The functions are:
4354 gnutls_certificate_set_openpgp_key_file
4355 gnutls_certificate_set_openpgp_key_mem
4356 gnutls_certificate_set_openpgp_keyring_mem
4357 gnutls_certificate_set_openpgp_keyring_file
4359 To improve terminology and align with the X.509 interface, some
4360 functions have been renamed. Compatibility mappings exists. The old
4361 and new names of the affected functions and types are:
4364 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4365 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
4366 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
4367 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
4368 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
4369 gnutls_openpgp_key_init gnutls_openpgp_crt_init
4370 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
4371 gnutls_openpgp_key_import gnutls_openpgp_crt_import
4372 gnutls_openpgp_key_export gnutls_openpgp_crt_export
4373 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
4374 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
4375 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
4376 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
4377 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
4378 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
4379 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
4380 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id

4382 gnutls_openpgp_send_key gnutls_openpgp_send_cert
4384 ** API and ABI modifications:
4385 No changes since last version.
4387 * Version 2.1.8 (released 2007-12-10)
4389 ** The GPL version has been changed from version 2 to version 3.
4390 This affects the self-tests, command-line tools, the libgnutls-extra
4391 library, the relevant guile parts, and the build environment.
4393 ** Added gnutls_x509_crt_get_subject_alt_name2().
4395 ** Corrected a segfault when setting an empty gnutls_priority_t
4396 at gnutls_priority_set().

4406 ** PKCS #8 parser can now encode/decode DSA keys.
4408 ** Updated gnutls_set_default_priority2() now renamed to
4409 gnutls_priority_set() and gnutls_priority_set_direct() which
4410 accept a string to indicate preferences of ciphersuite parameters.
4412 ** gnutls-cli and gnutls-serv now have a --priority option to set
4413 the priority string.
4415 ** The gnutls_*_convert_priority() functions were deprecated by
4416 the gnutls_priority_set() and gnutls_priority_set_direct().
4418 ** Internal copy of OpenCDK upgraded to version 0.6.6.

4460 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4463 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4464 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4465 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4466 documented. This caused some problems (e.g., debian #450854). To
4467 avoid backwards compatibility problems, this release revert this
4468 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4469 done in GnuTLS 2.0.x and earlier, and add a new error code
4470 GNUTLS_E_UNKNOWN_ALGORITHM.
4472 ** Fixes several gtk-doc warnings.
4474 ** API and ABI modifications:
4475 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.

4479 * Version 2.1.5 (released 2007-11-01)
4481 ** Fix PKCS#3 parameter export problem.
4483 ** Improve certtool queries, they now print the default value.
4487 ** Update gnulib files.
4489 ** API and ABI modifications:

4492 * Version 2.1.4 (released 2007-10-27)
4494 ** Added the --v1 option to certtool, to allow generating X.509
4495 version 1 certificates.
4497 ** certtool: Add option --disable-quick-random to enable the old behaviour
4498 of using /dev/random to generate keys.
4500 ** Added priority functions that accept strings.
4502 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4503 priorities preferences.
4505 ** Added gnutls_record_disable_padding() to allow servers talking to
4506 buggy clients that complain if the TLS 1.0 record protocol padding is
4509 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4510 all supported compatibility options (like disabling padding).
4512 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4513 the format. This makes the interface consistent with the x509 functions.

4557 This technique may be patented in the future, and it is not of crucial
4558 importance for the Internet community. After deliberation we have

4592 ** Removed all the xml related stubs and functions.
4594 ** Added capability to set a callback after the client hello is received
4595 by the server in order to adjust parameters before the handshake.
4597 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
4599 ** Corrected bug which did not allow a server to run without supporting
4602 ** Updated the DN parser which now prints wrongly decoded values as hex
4605 ** certtool: Add option --quick-random.
4606 For generating low security test credentials.
4608 ** API and ABI modifications:
4609 gnutls_x509_crt_to_xml: REMOVED
4610 gnutls_openpgp_key_to_xml: REMOVED
4611 gnutls_openpgp_key_verify_trustdb: REMOVED
4612 gnutls_openpgp_trustdb_init: REMOVED
4613 gnutls_openpgp_trustdb_deinit: REMOVED
4614 gnutls_openpgp_trustdb_import: REMOVED
4615 gnutls_certificate_set_openpgp_trustdb: REMOVED
4616 gnutls_srp_client_credentials_function: CHANGED
4617 gnutls_handshake_set_post_client_hello_function: ADDED
4618 gnutls_mac_get_key_size: ADDED
4619 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED: DEPRECATED.
4620 GNUTLS_A_MISSING_SRP_USERNAME: DEPRECATED
4621 GNUTLS_A_UNKNOWN_SRP_USERNAME: DEPRECATED
4623 * Version 2.1.1 (released 2007-09-24)
4625 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4626 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4627 compiled with Camellia support. See the libgcrypt documentation on
4628 how to enable it. Unconditionally disable it using the configure
4629 option --disable-camellia. Fixes #1.
4631 ** Properly document in the NEWS file the API change in the last release.
4633 ** API and ABI modifications:
4634 No changes since last version.
4636 * Version 2.1.0 (released 2007-09-20)
4638 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
4639 The support is disabled by default. Since no value has been allocated
4640 by the IANA for this extension yet, you will need to provide one
4641 yourself by invoking './configure --enable-opaque-prf-input=42'.
4644 ** Example code: Fix compilation flaw under MinGW.
4646 ** API and ABI modifications:
4647 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
4648 gnutls_oprfi_enable_client: ADD, new function.
4649 gnutls_oprfi_enable_server: ADD, new function.
4651 * Version 2.0.4 (released 2007-11-16)
4653 ** Corrected bug in decompression of expanded compression data.
4655 ** API and ABI modifications:
4656 No changes since last version.
4658 * Version 2.0.3 (released 2007-11-10)
4660 ** This version backports several fixes from the 2.1.x branch.
4662 ** Fixed PKCS #3 parameter export.
4664 ** Added gnutls_record_disable_padding() to allow servers talking to
4665 buggy clients that complain if the TLS 1.0 record protocol padding is
4668 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4669 all supported compatibility options (like disabling padding).
4671 ** Corrected bug which did not allow a server to run without supporting
4674 ** API and ABI modifications:
4675 gnutls_session_enable_compatibility_mode: ADDED
4676 gnutls_record_disable_padding: ADDED
4678 * Version 2.0.2 (released 2007-10-17)
4680 ** TLS authorization support removed.
4681 This technique may be patented in the future, and it is not of crucial
4682 importance for the Internet community. After deliberation we have
4683 concluded that the best thing we can do in this situation is to
4684 encourage society not to adopt this technique. We have decided to
4685 lead the way with our own actions.
4687 ** certtool: Fixed data corruption when using --outder.
4689 ** Fix configure-time Guile detection.
4691 ** API and ABI modifications:
4692 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4693 gnutls_supplemental_data_format_type_t enum type becomes empty.
4695 * Version 2.0.1 (released 2007-09-20)
4697 ** New directory doc/credentials/ with test credentials.
4698 This collects the test credentials from the web page and from src/.
4699 The script gnutls-http-serv has also been moved to that directory.
4701 ** Update SRP extension type and cipher suite with official IANA values.
4702 This breaks backwards compatibility with SRP in older versions of
4703 GnuTLS, but this is intentional to speed up the adoption of the
4704 official values. The old values we used were incorrect.
4706 ** Guile: Fix `x509-certificate-dn-oid'
4708 ** API and ABI modifications:
4709 No changes since last version.
4711 * Version 2.0.0 (released 2007-09-04)
4713 ** Included copy of Libtasn1 upgraded to version 1.1.
4715 ** Disable building of some examples if anonymous ciphers are disabled.
4717 ** Don't build examples for disabled features.
4719 ** API and ABI modifications:
4720 No changes since last version.
4722 * Version 1.7.19 (released 2007-08-27)
4724 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4725 This solves connection problems in mutt, see
4726 <http://bugs.debian.org/439640>.
4728 ** Update gnulib files.
4729 In particular, the getpass module -- with its dependencies on getline,
4730 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4731 library) directory to the gl/ directory (only used by the command line
4732 tools). The reason is that getpass is now only used by the
4733 command-line tools, and reducing the number of gnulib modules linked
4734 to the core library helps portability and reduces size.
4738 ** Disable building of PGP examples if PGP is disabled.
4740 ** Included copy of OpenCDK upgraded to version 0.6.4.
4742 ** API and ABI modifications:
4743 No changes since last version.
4745 * Version 1.7.18 (released 2007-08-16)
4747 ** Install images for the info manual.
4748 This has a side effect of renaming the images. See
4749 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4750 discussions on the approach chosen.
4752 ** Fix pointer mix to variables of different size.
4753 Patch extracted from
4754 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4756 ** Fix warnings during build.
4757 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4759 ** API and ABI modifications:
4760 No changes since last version.
4762 * Version 1.7.17 (released 2007-08-15)
4764 ** New functions to perform external signing.
4765 Set the signing callback function (of the gnutls_sign_func prototype)
4766 using the gnutls_sign_callback_set function. In the callback, you may
4767 find the new functions gnutls_x509_privkey_sign_hash and
4768 gnutls_openpgp_privkey_sign_hash useful. A new function
4769 gnutls_sign_callback_get is also added, to retrieve the function
4770 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4771 comments and testing.
4773 ** New self test of client and server authenticated X.509 TLS sessions.
4774 See tests/x509self.c and tests/x509signself.c. The latter also tests
4775 the new external signing callback interface.
4777 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4778 These two actually describe the outer limits of a range of error codes
4779 reserved to the application. All of the errors are treated as fatal
4780 by the library (it has to since it doesn't know the semantics of the
4781 error codes). This can be useful in callbacks, to signal some
4782 application-specific error condition, which will usually eventually
4783 cause some gnutls API to return the same error code as the callback,
4784 which then can be inspected by the application. Note that error codes
4787 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4788 The RFC is not released yet, and we're approaching a major release so
4789 let's not enable it just yet.
4791 ** Fix namespace so that gnutls_*_t is used consistently.
4792 Before, many places in the GnuTLS code used the old deprecated type
4793 names without the '_t' suffix.
4795 ** Build fixes for Guile code.
4796 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4798 ** More documentation fixes.
4799 In particular, the section headings were modified for casing. By
4800 Ludovic Courtes <ludovic.courtes@laas.fr>.
4802 ** Updated Polish and Swedish translations.
4803 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4804 <po@danielnylander.se>.
4806 ** API and ABI modifications:
4807 gnutls_sign_func: ADD, new type for sign callback.
4808 gnutls_sign_callback_set: ADD, new function to set sign callback.
4809 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4810 gnutls_x509_privkey_sign_hash,
4811 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4812 GNUTLS_E_APPLICATION_ERROR_MIN,
4813 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4815 * Version 1.7.16 (released 2007-08-07)
4817 ** Fix sanity checks and return values in certificate selection.
4818 In some cases, GnuTLS omitted to report suitable error codes when no
4819 suitable certificate was found.
4821 ** Fix gnutls-cli starttls EOF on Mac OS X.
4822 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4824 ** Documentation fixes.
4825 In particular, the section headings were modified for casing. By
4826 Ludovic Courtes <ludovic.courtes@laas.fr>.
4828 ** Update gnulib files.
4830 ** API and ABI modifications:
4831 No changes since last version.
4833 * Version 1.7.15 (released 2007-07-02)
4835 ** Fix self-tests key-id under mingw32.
4837 ** Test that the Guile header files are recent enough to work.
4838 Before we just tested that the command line tool 'guile' was recent
4839 enough, which may not be sufficient if you still have an old
4840 libguile.h header installed.
4842 ** Guile bindings are now installed under $prefix by default.
4843 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4844 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4845 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4846 The default, --with-guile-site-dir, will install the Guile bindings
4847 under $datadir/guile/site. There is a new section 'Guile
4848 Preparations' in the manual that discuss these issues.
4850 ** Fix run-time library path ordering in linking the Guile bindings.
4852 ** Improved manual on downloading, installing, getting help, bug reports etc.
4853 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4855 ** Add Malay message translations.
4856 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
4858 ** API and ABI modifications:
4859 No changes since last version.
4861 * Version 1.7.14 (released 2007-06-26)
4863 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
4864 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4866 ** Fix memory leak during DSA signature verification.
4867 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4869 ** Fix crash in gnutls-cli when TLS handshake fails.
4870 Reported by Marc Haber <mh+debian-bugs@zugschlus.de> and Andreas
4871 Metzler <ametzler@downhill.at.eu.org> via Debian BTS #429183, see
4872 <http://bugs.debian.org/429183>.

4875 Patch from Timo Schulz <twoaday@freakmail.de> and Ludovic Courtès
4876 <ludovic.courtes@laas.fr>.
4878 ** Fix off-by-one in TLS 1.2 handshake.
4879 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4881 ** Minor Guile binding self-test cleanup.
4882 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4884 ** Update gnulib files.
4886 ** API and ABI modifications:
4887 No changes since last version.
4889 * Version 1.7.13 (released 2007-06-11)
4891 ** OpenCDK copy updated to version 0.6.3.
4893 ** Build fixes for GnuTLS Guile bindings.
4894 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4896 ** Build fix for GTK-DOC manual.
4898 ** Update gnulib files.
4900 ** API and ABI modifications:
4901 No changes since last version.
4903 * Version 1.7.12 (released 2007-06-08)
4905 ** Guile bindings for GnuTLS have been included.
4906 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
4907 new chapter 'Guile Bindings' in the manual.
4909 ** Have PKCS8 parser return better error codes.
4910 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4911 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4912 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4914 ** Fix mem leak for sessions with client authentication via certificates.
4915 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4916 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4919 Reported by Dennis Vshivkov <walrus@amur.ru>, see
4920 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
4921 self-test tests/parse_ca.c to test regressions.
4923 ** Fix build failures related to missing images in manual.
4924 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4926 ** Update gnulib files.
4928 ** API and ABI modifications:
4929 No changes since last version.
4931 * Version 1.7.11 (released 2007-05-26)
4933 ** Include opencdk.h in the release.
4934 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4936 ** API and ABI modifications:
4937 No changes since last version.
4939 * Version 1.7.10 (released 2007-05-25)
4941 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4942 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4944 ** Update of gnulib files.
4946 ** GnuTLS is now developed in GIT instead of CVS.
4947 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4949 ** API and ABI modifications:
4950 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4951 gnutls_x509_crt_get_raw_dn: ADD.
4953 * Version 1.7.9 (released 2007-05-12)
4955 ** X.509 certificates are preferred over OpenPGP keys.
4956 This is a change in the semantics of gnutls_set_default_priority.
4958 ** The included copy of OpenCDK has been updated to 0.6.1.
4959 There has been some API changes in OpenCDK, and the GnuTLS layer have
4960 been modified as well. Note that while there are API/ABI incompatible
4961 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4962 its API/ABI have not changed. From this version on, GnuTLS requires
4963 OpenCDK 0.6.0 or later.
4965 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4967 ** Change certtool's default serial number from 0 to a time-based value.
4969 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4970 Before, we remove the parameters field, which resulted in a slightly
4971 different DER encoding which in turn caused signature verification
4972 failures of GnuTLS-generated RSA certificates in some other
4973 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4974 you read, this may or may not be correct, but our new behaviour appear
4975 to be consistent with other widely used implementations.
4977 ** Fix mem leaks in gnutls_x509_crt_print.
4979 ** API and ABI modifications:
4980 No changes since last version.
4982 * Version 1.7.8 (released 2007-04-16)
4984 ** Added examples for the authorization extension.
4985 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4987 ** The examples only use gnutls_set_default_priority().
4988 The exception is when DH_ANON is needed.
4990 ** Improve gnutls_set_default_priority() priorities.
4991 The new approach is for it to try and negotiate all secure and
4992 standard mechanisms available. Currently, DH_ANON ciphersuites and
4993 LZO compressions are not enabled by default, because they are,
4994 respectively, insecure and non-standardized. Note that TLS 1.2 will
4995 not be enabled by default in non-experimental release until it has
4996 been approved by the IETF.
4998 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4999 This means that to get DH_ANON and LZO compression, you'll need to
5000 specify that manually using '--kx anon' or '--comp lzo'.
5002 ** Minor fixes to the human display format of X.509 certificates.
5004 ** New APIs to extract Distinguished Name's from X.509 certificates.
5005 Based on patch from Howard Chu <hyc@symas.com>.
5007 ** Improved library searching for opencdk.
5008 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
5009 The deprecated opencdk.m4 is no longer used.
5011 ** New APIs to list supported algorithms in the library.
5012 The APIs are gnutls_cipher_list, gnutls_mac_list,
5013 gnutls_compression_list, gnutls_protocol_list,
5014 gnutls_certificate_type_list, gnutls_kx_list, and
5015 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
5017 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
5019 ** New configure option --disable-tls-authorization to disable tls-authz.
5021 ** Fix prototype for `gnutls_psk_set_client_credentials'.
5022 The last parameter was renamed from 'flags' to 'format' and the type
5023 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
5024 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
5027 ** Fix allocation in gnutls_certificate_set_openpgp_key.
5028 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
5030 ** API and ABI modifications:
5031 gnutls_x509_dn_t: ADD.
5032 gnutls_x509_ava_st: ADD.
5033 gnutls_x509_crt_get_subject,
5034 gnutls_x509_crt_get_issuer: ADD.
5035 gnutls_x509_dn_get_rdn_ava: ADD.
5036 gnutls_cipher_list: ADD.
5037 gnutls_mac_list: ADD.
5038 gnutls_compression_list: ADD.
5039 gnutls_protocol_list: ADD.
5040 gnutls_certificate_type_list: ADD.
5041 gnutls_kx_list: ADD.
5042 gnutls_cipher_suite_info: ADD.
5044 * Version 1.7.7 (released 2007-02-22)
5046 ** Support for supplemental handshake messages and authorization data.
5047 Supplemental data is described in RFC 4680 and the authorization
5048 extensions in draft-housley-tls-authz-extns-07.
5050 ** Support for authorization data in gnutls-cli and gnutls-serv.
5051 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
5053 ** Fix for gnutls_x509_crt_check_hostname.
5054 Before it would have reported that the certificate matched a hostname
5055 when it did not have any dNSName or any CN field. Report and tiny
5056 patch from "Richard W.M. Jones" <rjones@redhat.com>.
5058 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
5059 Tests regressions of the bug, and several other features.
5061 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
5062 Before there were no support for iPAddress SAN's during comparison.
5064 ** New API to print information about CRL's.
5065 The function is gnutls_x509_crl_print.
5067 ** New API to extract signature value from CRL's.
5068 The function is gnutls_x509_crl_get_signature.
5070 ** Support for directoryName Subject Alternative Name's.
5071 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
5072 string in the provided buffer.
5074 ** Internal improvements to certtool.
5075 It uses gnutls_x509_crl_print to print CRL information. It uses some
5076 more gnulib modules to simplify error handling.
5078 ** API and ABI modifications:
5079 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
5080 gnutls_supplemental_data_format_type_t: ADD.
5081 gnutls_authz_data_format_type_t: ADD.
5082 gnutls_supplemental_get_name: ADD.
5083 gnutls_authz_recv_callback_func,
5084 gnutls_authz_send_callback_func: ADD, callback prototypes.
5085 gnutls_authz_enable: ADD.
5086 gnutls_authz_send_x509_attr_cert,
5087 gnutls_authz_send_saml_assertion,
5088 gnutls_authz_send_x509_attr_cert_url,
5089 gnutls_authz_send_saml_assertion_url: ADD.
5090 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
5091 gnutls_x509_crl_print: ADD.
5092 gnutls_x509_crl_get_signature: ADD.
5094 * Version 1.7.6 (released 2007-02-12)
5096 ** Support for 'otherName' Subject Alternative Names.
5097 The existing API gnutls_x509_crt_get_subject_alt_name may now return
5098 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
5099 To find out the otherName OID (necessary for proper parsing of the
5100 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
5101 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
5102 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
5103 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
5105 ** Certtool can print otherName SAN values for certificates.
5106 For known otherName OIDs (currently only id-on-xmppAddr as defined by
5107 RFC 3920), it will also print the name.
5109 ** Fix TLS 1.2 RSA signing in servers.
5110 Before it used the old-style MD5+SHA1 signature, but the TLS
5111 signatures should be normal PKCS#1 signatures. FYI, we use and
5112 require that DigestInfo parameters are present and NULL for TLS 1.2.
5114 ** Add APIs to access X.509 extensions sequentially.
5115 The existing APIs gnutls_x509_crt_get_extension_oid() and
5116 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
5117 inspect the extensions in the order defined by the certificate.
5119 ** Add API to extract signature value from X.509 certificates.
5120 The function is gnutls_x509_crt_get_signature.
5122 ** Fix crash when generating proxy certificates in batch mode.
5123 If you don't specify a proxy policy in batch mode, it will use
5126 ** Add API to print information about X.509 certificates.
5127 The function is gnutls_x509_crt_print.
5129 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
5130 One consequence of this is that the output syntax has changed
5131 slightly. Some more fields are printed.
5135 ** API and ABI modifications:
5136 gnutls_x509_crt_print: ADD
5137 gnutls_certificate_print_formats_t: ADD, new enum.
5138 gnutls_x509_crt_get_signature: ADD.
5139 gnutls_x509_crt_get_extension_data: ADD.
5140 gnutls_x509_crt_get_extension_info: ADD.
5141 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
5142 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
5143 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
5145 * Version 1.7.5 (released 2007-02-06)
5147 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
5150 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
5152 ** Fix --list output for gnutls-cli and gnutls-serv.
5153 Mention TLS1.2, SHA512 etc.
5155 ** Manual contains new section on setting up a test HTTP server.
5156 A server set up following those descriptions are available online via
5157 <http://www.gnutls.org/server.html>.
5159 ** Update of gnulib files.
5161 ** API and ABI modifications:
5162 No changes since last version.
5164 * Version 1.7.4 (released 2007-02-05)
5166 ** Support for RSA signing using SHA-256/384/512.
5167 A new self test "sha2" tries to build a long X.509 certificate chain
5168 testing all new hashes.
5170 ** The gnutls-serv tool now use static DH parameters if none are supplied.
5172 ** Discuss proxy certificates in the manual.
5174 ** Improve bibliographical citations in the manual.
5176 ** Update of gnulib files.
5178 ** Fix certtool template handling of pathLenConstraints.
5179 It now defaults to -1 instead of 0, which causes the field to be
5180 missing unless the template specify it.
5182 ** API and ABI modifications:
5185 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
5188 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
5189 GNUTLS_SIGN_RSA_SHA256,
5190 GNUTLS_SIGN_RSA_SHA384,
5191 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
5193 * Version 1.7.3 (released 2007-02-01)
5195 ** New option to certtool: --generate-proxy.
5196 This will generate a Proxy Certificate from an end entity certificate.
5197 Proxy Certificates are documented in RFC 3820. You will need to
5198 specify the proxy certificate's private key with --load-privkey, the
5199 user certificate with --load-certificate and the private key used to
5200 sign the new proxy certificate with --load-ca-privkey. Certtool will
5201 query for proxy path length and the policy language OID. Currently
5202 only OIDs that have an empty policy are supported (which includes the
5203 two OIDs defined by RFC 3820).
5205 ** Certtool --certificate-info now prints information for Proxy Certificates.
5206 Before the proxy extension was just printed as DER encoded data.
5208 ** New APIs to set proxy subject names and get/set proxy cert extension.
5210 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
5212 ** Added self-test to test for regressions of pathLenConstraint bug.
5213 Incidentally, this also test (some) other regressions or changes in
5214 the output from certtool --certificate-info.
5216 ** When certtool generates CA certificates, pressing enter on the path
5217 ** length constraint query will now remove the field.
5218 Before it set the path length constraint to 0, which is a rather poor
5221 ** Certtool now print times in UTC when printing certificate/CRL info.
5223 ** Add better fix to work around C++ compiler bug on Mac OS X.
5224 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
5226 ** Fix import of ASCII armored OpenPGP keys.
5227 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
5229 ** Update of gnulib files.
5231 ** API and ABI modifications:
5232 gnutls_x509_crt_set_proxy_dn: ADD.
5233 gnutls_x509_crt_set_proxy: ADD.
5234 gnutls_x509_crt_get_proxy: ADD.
5236 * Version 1.7.2 (released 2007-01-14)
5238 ** Certtool now print the value of the pathLenConstraints field for certs.
5240 ** Certtool now query for path length constraints when generating CA certs.
5241 For batch uses, the certtool configuration name is "path_len".
5242 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5244 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
5245 The new functions gnutls_x509_crt_get_basic_constraints and
5246 gnutls_x509_crt_set_basic_constraints provide a superset of the
5247 functionality in the old gnutls_x509_crt_get_ca_status and
5248 gnutls_x509_crt_set_ca_status (respectively), but the old functions
5249 will continue to be supported.
5251 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5252 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5253 OpenCDK release with this patch will be made soon, which should bump
5254 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5256 ** Certtool --to-p12 can now store more than one certificate in the blob.
5257 Before it could only store one certificate, but now it will read and
5258 store as many certificate there are from the --load-certificate file.
5259 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5261 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5262 In particular, the OpenPGP function variables are no longer part of
5263 the exported libgnutls interface, and no header files from
5264 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5265 were never intended for non-internal purposes, and thus this does not
5266 imply a change in the external API/ABI.
5268 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5269 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5271 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5272 Before these parameters were set to make GnuTLS build under mingw32,
5273 however, they appear to no longer be necessary.
5275 ** A minor fix to the C++ library to make it build.
5276 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5278 ** Update of gnulib files.
5280 ** API and ABI modifications:
5281 gnutls_x509_crt_get_basic_constraints: ADD.
5282 gnutls_x509_crt_set_basic_constraints: ADD.
5283 cdk_pubkey_to_sexp: ADD (in opencdk).
5284 cdk_seckey_to_sexp: ADD (in opencdk).
5286 * Version 1.7.1 (released 2006-12-28)
5288 ** TLS 1.2 server side fix.
5289 The Certificate Request sent did not contain the list of supported
5290 hashes field, thus violating the protocol. It will now contain an
5291 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5293 ** TLS 1.2 DSA signature verification fix.
5294 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5296 ** Fix the list of trusted CAs that server's send to clients.
5297 Before, the list contained issuer DN's instead of subject DN's of the
5298 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5300 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5301 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5302 function. Reported by Max Kellermann <max@duempel.org>.
5304 ** Encode UID fields in DN's as DirectoryString.
5305 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5306 incorrect, it should have used DirectoryString. Now it will use
5307 DirectoryString for the UID field, but for backwards compatibility it
5308 will also accept IA5String UID's. Reported by Max Kellermann
5311 ** Improve out-of-sourcedir builds from CVS.
5312 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5314 ** Bootstrap tools changed.
5315 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5316 building GnuTLS from CVS. Libtool 1.5.22 is used.
5318 ** Fixed a syntax error in lib/gnutls.asn.
5319 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5321 ** Added German translation of GnuTLS messages.
5323 ** Update of gnulib files.
5325 ** API and ABI modifications:
5326 No changes since last version.
5328 * Version 1.7.0 (released 2006-11-29)
5330 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5331 The details is that the protocol priority set by
5332 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5333 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5335 ** Preliminary support for TLS 1.2.
5336 The client has been successfully tested against
5337 https://www.mikestoolbox.org:4433/.
5339 ** Anonself test now print a lot of debugging info, including TLS version.
5341 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5343 ** Update of gnulib files.
5345 ** API and ABI modifications:
5346 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5348 *** Pulled up from stable 1.6.x branch:
5350 ** Fix ./configure failure with non-GCC compilers.
5351 This fixes the following error message:
5352 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5353 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5355 * Version 1.6.3 (released 2007-05-26)
5357 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5358 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5359 from the 1.7.x branch, see
5360 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5362 ** Have PKCS8 parser return better error codes.
5363 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
5364 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
5365 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5367 ** Fix mem leak for sessions with client authentication via certificates.
5368 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5369 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5371 ** Fix building of 'tlsia' self test.
5372 Earlier some gcc are known to build tlsia linking to
5373 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5374 the build directory, even though command line parameters look OK.
5375 Changing order of some parameters fixes it.
5377 ** API and ABI modifications:
5378 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5379 gnutls_x509_crt_get_raw_dn: ADD.
5381 * Version 1.6.2 (released 2007-04-18)
5383 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5384 Before, we remove the parameters field, which resulted in a slightly
5385 different DER encoding which in turn caused signature verification
5386 failures of GnuTLS-generated RSA certificates in some other
5387 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5388 you read, this may or may not be correct, but our new behaviour appear
5389 to be consistent with other widely used implementations.
5391 ** Regenerate the PKIX ASN.1 syntax tree.
5392 For some reason, after changing the ASN.1 type of ldap-UID in the last
5393 release, the generated C file built from the ASN.1 schema was not
5394 refreshed. This can cause problems when reading/writing UID
5395 components inside X.500 Distinguished Names. Reported by devel
5396 <dev001@pas-world.com>.
5398 ** Updated translations.
5400 ** API and ABI modifications:
5401 No changes since last version.
5403 * Version 1.6.1 (released 2006-12-28)
5405 ** Fix the list of trusted CAs that server's send to clients.
5406 Before, the list contained issuer DN's instead of subject DN's of the
5407 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5409 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5410 Reported by Max Kellermann <max@duempel.org>.
5412 ** Encode UID fields in DN's as DirectoryString.
5413 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5414 incorrect, it should have used DirectoryString. Now it will use
5415 DirectoryString for the UID field, but for backwards compatibility it
5416 will also accept IA5String UID's. Reported by Max Kellermann
5419 ** Fix ./configure failure with non-GCC compilers.
5420 This fixes the following error message:
5421 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5422 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5424 ** API and ABI modifications:
5425 No changes since last version.
5427 * Version 1.6.0 (released 2006-11-17)
5429 ** No changes since 1.5.5.
5430 The major changes compared to the 1.4.x branch are:
5432 *** A GnuTLS C++ library is part of the official distribution.
5433 Currently there are no examples or documentation, but hopefully this
5434 will change. See gnutlsxx.h for the API.
5436 *** Windows is a supported platform.
5437 There are, however, two know bugs. One is related to select() in
5438 command line tools (not, nota bene, in the library), the other is a
5439 problem with libgcrypt that causes delays. Help is needed to resolve
5440 those issues, so we feel we can't delay the release because of this.
5442 *** New APIs for custom push/pull function error reporting.
5443 The new APIs are gnutls_transport_set_errno and
5444 gnutls_transport_set_global_errno. See the release notes for version
5445 1.5.4 for more information.
5447 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5449 * Version 1.5.5 (released 2006-11-16)
5451 ** Correctly bump shared library version after adding new APIs.
5452 This was forgotten in the last release.
5454 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5455 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5457 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5459 ** Update of gnulib files.
5461 ** API and ABI modifications:
5462 No changes since last version.
5464 * Version 1.5.4 (released 2006-11-07)
5466 ** New API functions to set errno in push/pull functions.
5467 Under Windows, setting the errno variable in a push/pull replacement
5468 may end up setting the wrong errno variable, and GnuTLS send/recv
5469 functions become confused about the real errno returned from a failed
5470 push/pull function. Therefor, we have added two APIs to set the errno
5471 variable used by GnuTLS. The APIs can also help to keep things
5472 thread-safe, by avoiding potentially global variables. Typically,
5473 instead of setting errno in your push/pull function, you will call one
5474 of these functions. It is recommended to use
5475 gnutls_transport_set_errno, but if you don't have the session variable
5476 easily accessible in the push/pull replacement function, you can use
5477 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5478 <tim.kosse@filezilla-project.org>.
5480 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5481 void gnutls_transport_set_global_errno (int err);
5483 ** When calling `recv' or `send' Windows errors are handled properly.
5484 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5485 WSAGetLastError to access the error condition instead.
5487 ** Several OpenPGP API fixes.
5488 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5489 important fix is to change the return value of
5490 gnutls_openpgp_privkey_get_pk_algorithm and
5491 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5492 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5493 compatible with 'int').
5495 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5496 ** version, try to negotiate the highest version support by the GnuTLS server,
5497 ** instead of the lowest.
5498 Reported by <Pasi.Eronen@nokia.com>.
5500 ** Replace old constructs with use of gnulib modules.
5501 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5502 the code. If the headers doesn't exist on the target system, gnulib
5503 will make sure its replacement header files are used instead.
5505 ** Fix SOVERSION computation for *.def files.
5506 This fixes build errors similar to "No rule to make target
5507 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5509 ** gnutls_check-version uses strverscmp from gnulib.
5511 ** Update of gnulib files.
5513 ** API and ABI modifications:
5514 gnutls_transport_set_errno: ADD
5515 gnutls_transport_set_global_errno: ADD
5517 * Version 1.5.3 (released 2006-10-26)
5519 ** Add new self-test of RSA-MD5 signature chains.
5520 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5521 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5522 and is based on the work by Marc Stevens et al, see
5523 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5525 ** Re-factor self tests.
5527 ** The include copy of Libtasn1 is updated to version 0.3.7.
5529 ** The included copy of OpenCDK is updated to version 0.5.11.
5531 ** Fix the filename of the *.def file on Windows after library version bump.
5533 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5534 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5535 gnulib modules. Earlier we could only use the LGPL'ed module from
5536 gnulib, because two gnulib directories in the same project didn't
5539 ** API and ABI modifications:
5540 No changes since last version.
5542 * Version 1.5.2 (released 2006-10-03)
5544 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5545 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5546 shared library version than this version, so you'll have to remove
5547 them and possibly relink your applications. The reason for this is
5548 that no API/ABI changes have been made since the 1.4.x branch, and
5549 that incrementing the shared library version was a mistake. Reported
5550 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5552 ** Fix off-by-one error when computing length to malloc.
5553 The code is used by gnutls_openpgp_add_keyring_file and
5554 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5555 <agl@imperialviolet.org>.
5557 ** Add version script for the GnuTLS C++ library.
5558 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5560 ** Fix the C++ compiler detection logic.
5561 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5563 ** Update of gnulib files.
5565 ** API and ABI modifications:
5566 No changes since last version.
5568 * Version 1.5.1 (released 2006-09-21)
5570 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5571 ** Crypto 06 rump session attack.
5572 In particular, we check that the digestAlgorithm.parameters field is
5573 missing or empty, to avoid that it can contain "garbage" that may be
5574 used to alter the numeric properties of the signature. See
5575 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5576 not exactly the same as the problem we fix here). Reported by Yutaka
5577 OIWA <y.oiwa@aist.go.jp>.
5579 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5580 up to date information.
5582 ** Add self test to test for above flaw.
5584 ** Fix gnutls-cli-debug regarding resume support detection.
5585 Earlier, if the session-id from the server had a length of 0, it would
5586 indicate that the server supports resumption, which isn't the case.
5587 Reported by Kataja Kai <kai.kataja@op.fi>.
5589 ** Fix building of examples on FreeBSD by including netinet/in.h.
5590 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5592 ** Fix certtool bug that caused the private key to not be loaded when
5593 generating a certificate with --load-request, which in turn triggered
5594 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5595 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5597 ** gnutls-cli and gnutls-serv works on Windows.
5598 The problem was the select() call that doesn't work on file
5599 descriptors (stdin) on Windows. We borrowed some code from plibc to
5600 solve this. It appears to be somewhat unreliable though.
5602 ** Autoconf 2.60 is now used.
5604 ** API and ABI modifications:
5605 No changes since last version.
5607 * Version 1.5.0 (released 2006-08-13)
5609 ** Change SRP and Cert-Type extensions to match IANA registry.
5611 ** Fixed bug in OpenPGP authentication handshake.
5613 ** Improvements for building under MinGW.
5614 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5615 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5616 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5617 at run-time from ws2_32.dll, and falls back on a simple replacement if
5618 it is not available. Builds the library with -mms-bitfields
5619 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5620 create *.def files, which are installed.
5622 ** The examples now (conditionally) include config.h and link to gnulib.
5623 No other source changes were necessary, so the examples should
5624 continue to be possible to use stand-alone without any autoconf or
5627 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5628 You may unconditionally disable it with --disable-cxx. See
5629 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the

5633 This enables 'make distcheck' to succeed.

5645 ** API and ABI modifications:
5646 No changes since last version.
5648 * Version 1.4.5 (released 2006-11-06)
5650 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5651 ** version, try to negotiate the highest version support by the GnuTLS server,

5658 ** API and ABI modifications:
5659 No changes since last version.
5661 * Version 1.4.4 (released 2006-09-12)
5663 ** Relax the test that caught signatures that exploit the variant of
5664 ** Bleichenbacher's Crypto 06 rump session attack on our
5665 ** verification logic flaw.
5666 In particular, we now permit the digestAlgorithm.parameters field to
5667 be present but empty, whereas in 1.4.3 we actually checked that the
5670 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5671 The messages are only printed in debug mode, which is not recommended
5672 for normal use, and thus logging this situation cannot be abused as an
5673 oracle in typical recommended situations.
5675 ** API and ABI modifications:
5676 No changes since last version.
5678 * Version 1.4.3 (released 2006-09-08)
5680 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5681 ** Crypto 06 rump session attack.
5682 In particular, we check that the digestAlgorithm.parameters field is
5683 empty, to avoid that it can contain "garbage" that may be used to
5684 alter the numeric properties of the signature. See
5685 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5686 not exactly the same as the problem we fix here). Reported by Yutaka

5704 * Version 1.4.2 (released 2006-08-12)
5706 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5707 This can happen if you call gnutls_certificate_verify_peers2 and have
5708 a certain mix of local CA certificates and the peer send special
5709 certificates, that together trigger certain behaviour. It is not
5710 known at this point whether the crash can be triggered without the
5711 special local CA certificate, and thus turn this into a remote crash
5712 of clients that verify server certificates when they talk to a server
5713 with the special server certificate. See GNUTLS-SA-2006-2 on
5714 http://www.gnu.org/software/gnutls/security.html for more up to date
5715 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5717 ** Change SRP and Cert-Type extensions to match IANA registry.
5719 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5721 ** Make --without-included-libtasn1 work.
5722 Reported by Daniel Black <dragonheart@gentoo.org>.
5724 ** API and ABI modifications:
5725 No changes since last version.
5727 * Version 1.4.1 (released 2006-06-14)
5729 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5731 ** Fixed bug in OpenPGP authentication handshake.
5733 ** Fixed typographical in man pages.
5735 ** Build fixes of the manual.
5737 ** Added Swedish translation.
5739 ** API and ABI modifications:
5740 No changes since last version.
5742 * Version 1.4.0 (released 2006-05-15)
5744 ** Remove GnuTLS 0.8.x compatibility functions.
5746 ** The libgcrypt RNG is initialized in gnutls_global_init().
5748 ** TLS/IA API changes from Emile van Bergen.
5749 A dummy credential structure is not needed now, if you wish to use the
5750 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5753 ** The self-tests are now run under valgrind, if it is installed.
5755 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5757 ** The command line tools now use getaddrinfo and support IPv6.
5759 ** API and ABI modifications:
5760 _gnutls_x509_get_raw_crt_activation_time,
5761 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5762 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5763 gnutls_ia_enable: Added.
5765 * Version 1.3.5 (released 2006-03-08)
5767 ** Error messages are now translated using GNU Gettext.
5769 ** The function gnutls_x509_crt_to_xml now return an internal error.
5770 This means that the code to convert X.509 certificates to XML format
5771 does not work any more. The reason is that the function called
5772 libtasn1 internal functions. It seems unclean for libtasn1 to export
5773 the APIs needed here. Instead it would be better to implement XML
5774 support inside libtasn1 properly. If you need this functionality
5775 strongly, please consider looking into implementing this suggested
5776 approach instead. As a workaround, you may also modify lib/x509/xml.c
5777 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5779 ** Libraries are now built with libtool's -no-undefined.
5780 This helps producing libraries for Windows using mingw32.
5782 ** Doc fixes to explain that gnutls_record_send can block.
5784 ** Libtasn1 0.3.1 or later is now required.
5785 The include copy has been updated too.
5787 ** gnutls-cli can now recognize services and port numbers with the -p option.
5789 ** API and ABI modifications:
5790 No changes since last version.
5792 * Version 1.3.4 (released 2006-02-09)
5794 ** Fix read of out bounds bug in DER parser.
5795 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5796 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5797 previous bug fix. The included libtasn1 version in GnuTLS has been
5800 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5801 longer invalidate a session if the underlying send fails, but it will
5802 prevent future writes. That is to allow reading the already received data.
5803 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5805 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5806 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5807 more than one certificates were added. Report and patch by Max Kellermann.
5809 ** Fix build problems of OpenCDK on AIX.
5810 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5812 ** API and ABI modifications:
5813 No changes since last version.
5815 * Version 1.3.3 (released 2006-01-12)
5817 ** New API to access the TLS master secret.
5818 When possible, you should use the TLS PRF functions instead.
5819 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5821 ** Improved handling when multiple libraries use GnuTLS at the same time.
5822 Now gnutls_global_init() can be called multiple times, and
5823 gnutls_global_deinit() will only deallocate the structure when it has
5824 been called as many times as gnutls_global_init() was called.
5826 ** Added a self test of TLS resume functionality.
5828 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5830 ** Documentation fixes about thread unsafety, prompted by
5831 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5832 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5833 thread safe. Careful callers may want to protect the call using a
5834 mutex. The problem could also be ignored, which would cause a memory
5835 leak under rare conditions when two threads invoke the function
5836 roughly at the same time.
5838 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5840 ** The code was indented again, including the external header files.
5842 ** API and ABI modifications:
5843 New functions to retrieve the master secret value:
5844 gnutls_session_get_master_secret
5846 Add a 'const' keyword to existing API:
5847 gnutls_x509_crq_get_challenge_password
5849 * Version 1.3.2 (released 2005-12-15)
5851 ** GnuTLS now support TLS Inner application (TLS/IA).
5852 This is per draft-funk-tls-inner-application-extension-01. This
5853 functionality is added to libgnutls-extra, so it is licensed under the
5854 GNU General Public License.
5856 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5857 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5858 and EAP-TTLS. One function to access the raw PRF and one to access
5859 the PRF seeded with the client/server random fields are provided.
5860 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5862 ** New APIs to acceess the client and server random fields in a session.
5863 These fields can be useful by protocols using TLS. Note that these
5864 fields are typically used as input to the TLS PRF, and if this is your
5865 intended use, you should use the TLS PRF API that use the
5866 client/server random field directly. Suggested by Jouni Malinen
5867 <jkmaline@cc.hut.fi>.
5869 ** Internal type cleanups.
5870 The uint8, uint16, uint32 types have been replaced by uint8_t,
5871 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5872 correct types on platforms that lack them. The uint type have been
5873 replaced by unsigned.
5875 ** API and ABI modifications:
5876 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5880 New functions to retrieve the session's client and server random values:
5881 gnutls_session_get_server_random
5882 gnutls_session_get_client_random
5884 New function, to perform TLS/IA handshake:
5887 New function to decide whether to do a TLS/IA handshake:

5901 gnutls_ia_set_server_avp_ptr
5902 gnutls_ia_get_server_avp_ptr
5904 New functions, to toggle TLS/IA application phases:
5905 gnutls_ia_require_inner_phase
5907 New function to mix session keys with inner secret:
5908 gnutls_ia_permute_inner_secret
5910 Low-level API (used internally by gnutls_ia_handshake):
5911 gnutls_ia_endphase_send
5915 New functions that can be used after successful TLS/IA negotiation:
5916 gnutls_ia_generate_challenge
5917 gnutls_ia_extract_inner_secret
5919 Enum type with TLS/IA modes:
5922 Enum type with TLS/IA packet types:
5925 Enum values for TLS/IA alerts:
5926 GNUTLS_A_INNER_APPLICATION_FAILURE
5927 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5929 New error codes, to signal when an application phase has finished:
5930 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5931 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5933 New error code to signal TLS/IA verify failure:
5934 GNUTLS_E_IA_VERIFY_FAILED
5936 * Version 1.3.1 (released 2005-12-08)
5938 ** Support for DHE-PSK cipher suites has been added.
5939 This method offers perfect forward secrecy.
5941 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5942 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5944 ** Corrected a bug in certtool for 64 bit machines. Reported
5945 by Max Kellermann <max@duempel.org>.
5947 ** New function to set a X.509 private key and certificate pairs, and/or
5948 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5949 <emile@e-advies.nl>.
5951 The integrity of the PKCS#12 file is protected through a password
5952 based MAC; public-key based signatures for integrity protection are
5953 not supported. PKCS#12 bags may be encrypted using password derived
5954 symmetric keys, public-key based encryption is not supported. The
5955 PKCS#8 keys may be encrypted using passwords. The API use the same
5956 password for all operations. We believe that any more flexibility
5957 create too much complexity that would hurt overall security, but may
5958 add more PKCS#12 related APIs if real-world experience indicate
5961 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5962 reported by Emile van Bergen <emile@e-advies.nl>.
5963 This will enable "certtool -k -8" to parse those keys.
5965 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5966 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5967 certtool would have encrypted the key using an empty password.
5969 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5970 Earlier it would have prompted the user for it, even if --password was
5973 ** Added self test of PKCS#8 parsing.
5974 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5975 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5978 ** API and ABI modifications:
5979 New function to set X.509 credentials from a PKCS#12 file:
5980 gnutls_certificate_set_x509_simple_pkcs12_file
5982 New gnutls_kx_algorithm_t enum type:
5985 New API to return session data (basically same as gnutls_session_get_data):
5986 gnutls_session_get_data2
5988 New API to set PSK Diffie-Hellman parameters:
5989 gnutls_psk_set_server_dh_params
5991 * Version 1.3.0 (2005-11-15)
5993 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5994 This add several new APIs, see below. Read the updated manual for
5995 more information. A new self test "pskself" has been added, that will
5996 test this functionality.
5998 ** The session resumption data are now system independent.
6000 ** The code has been re-indented to conform to the GNU coding style.
6002 ** Removed the RIPEMD ciphersuites.
6004 ** Added a discussion of the internals of gnutls in manual.
6006 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
6008 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
6010 ** Make sure config.h is included first in a few files, from Albert Chin.
6012 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
6014 ** Don't install SRP programs and man pages if --disable-srp-authentication,

6020 New gnutls_credentials_type_t credential type:
6023 New credential types:
6024 gnutls_psk_server_credentials_t

6057 * Version 1.2.11 (2006-05-11)
6058 - The function gnutls_x509_crt_to_xml is not supported any more, and
6059 return an internal error. The reason is that the function called
6060 internal libtasn1 functions which are no longer exported from
6062 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
6063 - Updated gnulib compatibility files.
6064 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
6065 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
6066 - API and ABI modifications:
6067 No changes since last version.
6069 * Version 1.2.10 (2006-02-09)
6070 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
6071 <admin@gleg.net>, and debugging help from Protover SSL.
6072 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
6073 The included version has been updated too.
6074 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
6075 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
6076 - Corrected a bug in certtool for 64 bit machines. Reported
6077 by Max Kellermann <max@duempel.org>.
6078 - Corrected bugs in gnutls_certificate_set_x509_crl() and
6079 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6080 more than one certificates were added. Report and patch by Max Kellermann.
6081 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6082 longer invalidate a session if the underlying send fails, but it will
6083 prevent future writes. That is to allow reading the already received data.
6084 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6086 * Version 1.2.9 (2005-11-07)
6087 - Documentation was updated and improved.
6088 - RSA-MD2 is now supported for verifying digital signatures.
6089 - Due to cryptographic advances, verifying untrusted X.509
6090 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
6091 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
6092 applications that must remain interoperable, you can use the
6093 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
6094 flags when verifying certificates. Naturally, this is not
6095 recommended default behaviour for applications. To enable the
6096 broken algorithms, call gnutls_certificate_set_verify_flags with the
6097 proper flag, to change the verification mode used by
6098 gnutls_certificate_verify_peers2.
6099 - Make it possible to send empty data through gnutls_record_send,
6100 to align with the send(2) API.
6101 - Some changes in the certificate receiving part of handshake to prevent
6102 some possible errors with non-blocking servers.
6103 - Added numeric version symbols to permit simple CPP-based feature
6104 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
6105 - The (experimental) low-level crypto alternative to libgcrypt used
6106 earlier (Nettle) has been replaced with crypto code from gnulib.
6107 This leads to easier re-use of these components in other projects,
6108 leading to more review and simpler maintenance. The new configure
6109 parameter --with-builtin-crypto replace the old --with-nettle, and
6110 must be used if you wish to enable this functionality. See README
6111 under "Experimental" for more information. Internally, GnuTLS has
6112 been updated to use the new "Generic Crypto" API in gl/gc.h. The
6113 API is similar to the old crypto/gc.h, because the gnulib code were
6114 based on GnuTLS's gc.h.
6115 - Fix compiler warning in the "anonself" self test.
6116 - API and ABI modifications:
6117 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
6118 This doesn't reflect a change in behaviour,
6119 so we don't break backwards compatibility.
6120 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
6121 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
6122 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
6123 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
6125 gnutls_x509_crt_list_verify,
6126 gnutls_x509_crt_verify, or
6127 gnutls_certificate_set_verify_flags.
6128 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
6129 used when broken signature algorithms
6130 is used (currently RSA-MD2/MD5).
6131 LIBGNUTLS_VERSION_MAJOR,
6132 LIBGNUTLS_VERSION_MINOR,
6133 LIBGNUTLS_VERSION_PATCH,
6134 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
6135 version number, can be used for feature existence
6138 * Version 1.2.8 (2005-10-07)
6139 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
6140 - Don't install the auxilliary libexamples library used by the
6141 examples in doc/examples/ on "make install", report and tiny patch
6142 from Thomas Klausner <tk@giga.or.at>.
6143 - If you pass a X.509 CA or PGP trust database to the command line
6144 tool, it will now abort the connection if the server certificate
6145 validation fails. Use the parameter --insecure to continue even
6146 after certificate validation failures. Inspired from discussion
6147 with Alexander Kotelnikov <sacha@myxomop.com>.
6148 - The test for socklen_t has been moved to gnulib.
6149 - Link failures for duplicate or missing "program_name" symbol has been fixed,
6150 patch from Martin Lambers <marlam@marlam.de>.
6151 - The command line tool and the examples no longer uses mmap or bzero,
6152 to make them more portable, patch from Martin Lambers
6154 - Made the PKCS #12 API handle null passwords. Based on patch by
6155 Anton Altaparmakov <aia21@cam.ac.uk>.
6156 - The GTK-DOC manual should build with current released tools.
