5 * Version 3.1.2 (unreleased)
7 ** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
8 and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
9 of certificates in the windows platform.
11 ** libgnutls: Added X.509 certificate verification flag
12 GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
13 of unsorted certificate chains and is enabled by default for
14 TLS certificate verification (if gnutls_certificate_set_verify_flags()
15 does not override it).
17 ** libgnutls: Prints warning on certificates that contain keys of
18 an insecure level. If the %COMPAT priority flag is not specified
19 the TLS connection fails.
21 ** libgnutls: Better mingw32 support (patch by LRN).
23 ** libgnutls: The %COMPAT keyword, if specified, will tolerate
24 key usage violation errors (they are far too common to ignore).
26 ** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
27 which provides a tool to counter compression-related attacks where
28 parts of the data are controlled by the attacker _and_ placed in
29 separate records (use with care - do not use compression if not sure).
31 ** libgnutls: Depends on libtasn1 2.14 or later.
33 ** certtool: Prints the number of bits of the public key algorithm
34 parameter in a private key.
36 ** API and ABI modifications:
37 gnutls_x509_privkey_get_pk_algorithm2: Added
38 gnutls_heartbeat_ping: Added
39 gnutls_heartbeat_pong: Added
40 gnutls_heartbeat_allowed: Added
41 gnutls_heartbeat_enable: Added
42 GNUTLS_SEC_PARAM_WEAK: Added
43 GNUTLS_SEC_PARAM_INSECURE: Added
45 * Version 3.1.1 (released 2012-09-02)
47 ** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.
49 ** certtool: Changes in password handling of certtool.
50 Ask password when required and only if the '--password' option is not
51 given. If the '--password' option is given during key generation then
52 assume the PKCS #8 file format, instead of ignoring the password.
54 ** tpmtool: No longer asks for key password in registered keys.
56 ** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
57 wmNAF is now used for point multiplication and other optimizations.
58 (the major part of the work was done during Google Summer of Code).
60 ** libgnutls: The default pull_timeout_function only uses select
61 instead of a combination of select() and recv() to prevent issues
62 when used in stream sockets in some systems.
64 ** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
65 SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
68 ** libgnutls: Fixed DSA and ECDSA signature generation in smart
69 cards. Thanks to Andreas Schwier from cardcontact.de for providing
70 me with ECDSA capable smart cards.
72 ** API and ABI modifications:
73 gnutls_sign_algorithm_get: Added
74 gnutls_sign_get_hash_algorithm: Added
75 gnutls_sign_get_pk_algorithm: Added
78 * Version 3.1.0 (released 2012-08-15)
80 ** libgnutls: Added direct support for TPM as a cryptographic module
81 in gnutls/tpm.h. TPM keys can be used in functions accepting files
82 using URLs of the following types:
83 tpmkey:file=/path/to/file
84 tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user
86 ** libgnutls: Priority string level keywords can be combined.
87 For example the string "SECURE256:+SUITEB128" is now allowed.
89 ** libgnutls: requires libnettle 2.5.
91 ** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
92 for encryption and signatures.
94 ** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
95 generic errors and signature verification errors in the verification
98 ** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
99 to simplify parsing in most PKCS #12 use cases.
101 ** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
102 the whole certificate chain (if any) to the credentials structure, instead
103 of only the end-user certificate.
105 ** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
106 and gnutls_x509_privkey_import_pkcs8(), return consistently
107 GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
108 password was provided.
110 ** libgnutls: Added gnutls_handshake_set_timeout() a function that
111 allows to set the maximum time spent in a handshake.
113 ** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
116 ** tpmtool: Added. It is a tool to generate private keys in the
119 ** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
120 and --benchmark-tls-ciphers
122 ** certtool: generated PKCS #12 structures may hold more than one
123 private key. Patch by Lucas Fisher.
125 ** certtool: Added option --null-password to generate/decrypt keys
126 that use a NULL password (in schemas that distinguish between NULL

176 ** libgnutls: gnutls_certificate_set_x509_system_trust()
177 is now supported on OpenBSD.
179 ** libgnutls: When verifying a certificate chain make sure it is chain.
180 If the chain is wronly interrupted at some point then truncate it,
181 and only try to verify the correct part. Patch by David Woodhouse

201 GNUTLS_E_LARGE_PACKET instead of being truncated.
203 ** libgnutls: gnutls_dtls_get_data_mtu() is more precise. Based
204 on patch by David Woodhouse.
206 ** libgnutls: Fixed memory leak in PKCS #8 key import.
208 ** libgnutls: Added support for an old version of the DTLS protocol
209 used by openconnect vpn client for compatibility with Cisco's AnyConnect
210 SSL VPN. It is marked as GNUTLS_DTLS0_9. Do not use it for newer protocols
213 ** libgnutls: Corrected bug that prevented resolving PKCS #11 URLs
214 if only the label is specified. Patch by David Woodhouse.

249 gnutls_certificate_set_x509_system_trust: Added
252 * Version 3.0.19 (released 2012-04-22)
254 ** libgnutls: When decoding a PKCS #11 URL the pin-source field
255 is assumed to be a file that stores the pin. Based on patch
258 ** libgnutls: gnutls_record_check_pending() no longer
259 returns unprocessed data, and thus ensure the non-blocking
260 of the next call to gnutls_record_recv().
262 ** libgnutls: Added strict tests in Diffie-Hellman and
263 SRP key exchange public keys.

390 assumed (/etc/ssl/certs/ca-certificates.crt), if it exists.
392 ** ocsptool: Added --ask parameter, to verify a certificate's
393 status from an ocsp server.
395 ** command line apps: Use gnu autogen (libopts) to parse command

403 Report and patches by Sean Buckheister.
405 ** libgnutls: Added new functions to easily allow the usage of
406 a trust on first use (SSH-style) authentication.
408 ** libgnutls: SUITEB128 and SUITEB192 priority strings account
409 for the RFC6460 requirements.
411 ** libgnutls: Added new security parameter GNUTLS_SEC_PARAM_LEGACY
412 to account for security level of 96-bits.

418 ** libgnutls: Added functions to parse authority key identifiers
419 when stored as a 'general name' and serial combo.
421 ** libgnutls: Added function to force explicit reinitialization
422 of PKCS #11 modules. This is required on the child process after
423 a fork (if PKCS #11 functionality is desirable).

450 ** libgnutls: Added OCSP support.
451 There is a new header file gnutls/ocsp.h and a set of new functions
452 under the gnutls_ocsp namespace. Currently the functionality provided
453 is to parse and extract information from OCSP requests/responses, to
454 generate OCSP requests and to verify OCSP responses. See the manual
455 for more information. Run ./configure with --disable-ocsp to build
456 GnuTLS without OCSP support.
458 This work was sponsored by Smoothwall <http://smoothwall.net/>.
460 ** ocsptool: Added new command line tool.
461 The tool can parse OCSP request/responses, generate OCSP requests and

535 ** gnutls-cli/serv: Set don't fragment bit in DTLS sessions
536 in Linux as well as in BSD.
538 ** gnutls-cli: Fixed reading from windows terminals.
540 ** libgnutls: When GNUTLS_OPENPGP_FMT_BASE64 is specified
541 the stream is assumed to be base64 encoded (previously
542 the encoding was auto-detected). This avoids a decoding
543 issue in windows systems.
545 ** libgnutls: Corrected ciphersuite GNUTLS_ECDHE_PSK_AES_256_CBC_SHA384
547 ** libgnutls: Added ciphersuites: GNUTLS_PSK_WITH_AES_256_GCM_SHA384
548 and GNUTLS_DHE_PSK_WITH_AES_256_GCM_SHA384.
550 ** libgnutls: Added function gnutls_random_art() to convert
551 fingerprints to images (currently ascii-art).

565 it will only list the ciphersuites that are enabled by the given
568 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
569 changes the ciphersuite selection procedure. If specified the server
570 priorities will be used for selection instead of the client's.
572 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
575 ** libgnutls: When session tickets are negotiated and used in a
576 session, a server will not store that session data into its cache.
578 ** libgnutls: Added the SECP192R1 curve.
580 ** libgnutls: Added gnutls_priority_get_cipher_suite_index() to
581 allow listing the ciphersuites enabled in a priority structure.
582 It outputs an index to be used in gnutls_get_cipher_suite_info().
584 ** libgnutls: Optimizations in the elliptic curve code --timing
585 attacks resistant code is only used in ECDSA private key operations.
587 ** doc: man pages for API functions generation was fixed and are

1191 gnutls_x509_privkey_verify_data, gnutls_x509_crt_verify_data,
1192 gnutls_x509_crt_verify_hash return the negative error code
1193 GNUTLS_E_PK_SIG_VERIFY_FAILED if verification fails to simplify error
1196 ** libgnutls: Added helper functions for signature verification:
1197 gnutls_pubkey_verify_data() and gnutls_pubkey_import_privkey().
1199 ** libgnutls: Modified gnutls_privkey_sign_data().
1201 ** gnutls_x509_crl_privkey_sign2(), gnutls_x509_crq_sign2()
1202 gnutls_x509_privkey_sign_hash(), gnutls_x509_privkey_sign_data(),
1203 gnutls_x509_crt_verify_hash(), gnutls_x509_crt_verify_data(), were
1204 deprecated for gnutls_x509_crl_privkey_sign(),
1205 gnutls_x509_crq_privkey_sign(), gnutls_privkey_sign_hash(),
1206 gnutls_privkey_sign_data(), gnutls_pubkey_verify_hash()
1207 gnutls_pubkey_verify_data() respectively.
1209 ** libgnutls: gnutls_*_export_raw() functions now add leading zero in
1212 ** libgnutls: Added convenience functions gnutls_x509_crl_list_import2()
1213 and gnutls_x509_crt_list_import2().
1215 ** crypto.h: Fix use with C++.
1216 Reported by "Brendan Doherty" <brendand@gentrack.com>.

1243 gnutls_privkey_sign_hash: REMOVED (was added in 2.11.0)
1245 * Version 2.11.6 (released 2010-12-06)
1247 ** libgnutls: Record version of Client Hellos is now set by default to
1248 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
1251 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
1252 This makes us comply with RFC3279. Reported by Michael Rommel.
1254 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
1256 ** API and ABI modifications:
1257 No changes since last version.
1259 * Version 2.11.5 (released 2010-12-01)
1261 ** libgnutls: Reverted default behavior for verification and
1262 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
1263 V1 trusted CAs are allowed, unless the new flag is specified.
1265 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
1266 Reported by Jeffrey Walton.
1268 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
1269 as priority strings. Those allow to set all the supported algorithms
1272 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
1274 ** gnutls-cli: Print channel binding only in verbose mode.
1275 Before it printed it after the 'Compression:' output, thus breaking
1276 Emacs starttls.el string searches.
1278 ** API and ABI modifications:
1279 gnutls_pkcs11_token_init: New function
1280 gnutls_pkcs11_token_set_pin: New function
1282 * Version 2.11.4 (released 2010-10-15)
1284 ** libgnutls: Add new API gnutls_session_channel_binding.
1285 The function is used to get the channel binding data. Currently only
1286 the "tls-unique" (RFC 5929) channel binding type is supported, through
1287 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
1290 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
1292 ** doc: Added pkcs11.h header file to GTK-DOC manual.
1294 ** build: Update gnulib files.
1296 ** i18n: Update translations.
1298 ** tests: Add self tests gendh.c. Speed up Guile self checks.
1300 ** API and ABI modifications:
1301 gnutls_session_channel_binding: New function.
1302 gnutls_channel_binding_t: New enumeration.
1303 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
1304 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
1306 * Version 2.11.3 (released 2010-10-14)
1308 ** Indent code to follow the GNU Coding Standard.
1309 You should be able to unpack the 2.11.2 release and run 'make indent'
1310 twice to get exactly the same content as 2.11.3 except for generated
1311 files. Using GNU Indent 2.2.11.
1313 ** API and ABI modifications:
1314 No changes since last version.
1316 * Version 2.11.2 (released 2010-10-08)
1318 ** libgnutls: Several bug fixes on session resumption
1319 and session tickets support.
1321 ** libgnutls: Add new extended key usage ipsecIKE.
1323 ** certtool: Renamed PKCS #11 options to: --p11-provider,
1324 --p11-export-url, --p11-list-certs, --p11-list-certs,
1325 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
1326 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
1327 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1330 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1331 introduced with the new nettle code.
1333 ** libgnutls: Corrected advertizing issue for session tickets.
1335 ** API and ABI modifications:
1336 gnutls_x509_crt_get_subject_unique_id: ADDED.
1337 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1339 * Version 2.11.1 (released 2010-09-14)
1341 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1342 to use the libgcrypt back end.
1344 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1345 backend crypto library.
1347 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1349 ** libgnutls: Several updates in the buffering internal interface.
1351 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1352 tabs are being skipped.
1354 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1356 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1359 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1360 system calls. Applications that depended on it being 1 should explicitly call
1361 gnutls_transport_set_lowat().
1363 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1364 to ECRYPT II recommendations. Mappings were moved to a single location
1365 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1366 and 3072 keys only).
1368 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1369 gnutls_x509_privkey_import_pkcs8() without a password, if it
1370 is unable to decode the key.
1372 ** libgnutls: HMAC-MD5 no longer used by default.
1374 ** API and ABI modifications:
1375 gnutls_openpgp_privkey_sec_param: ADDED
1376 gnutls_x509_privkey_sec_param: ADDED
1378 * Version 2.11.0 (released 2010-07-22)
1380 ** libgnutls: support scattered write using writev(). This takes
1381 advantage of the new buffering layer and allows queuing of packets
1382 and flushing them. This is currently used for handshake messages
1385 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1386 alternative locking procedures. By default the system available
1387 locking is used. In *NIX pthreads are used and in windows the
1388 critical section API. This follows a different approach than the
1389 previous versions that depended on libgcrypt initialization. The
1390 locks are now set by default in systems that support it. Programs
1391 that used gcry_control() to set thread locks should insert it into
1393 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1397 ** libgnutls: Added support for reading DN from EV-certificates.
1399 jurisdictionOfIncorporationLocalityName,
1400 jurisdictionOfIncorporationStateOrProvinceName,
1401 jurisdictionOfIncorporationCountryName
1403 ** libgnutls: Added support for DSA signing/verifying with bit
1406 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1407 has to be called to register any required md5 handlers.
1409 ** libgnutls: Internal buffering code was replaced by simpler
1410 code contributed by Jonathan Bastien-Filiatrault.
1412 ** libgnutls: Internal API for extensions augmented to allow
1413 safe storing and loading of data on resumption. This allows writing
1414 self-contained extensions (when possible). As a side effect
1415 the OPRFI extension was removed.
1417 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1419 ** libgnutls: Added PKCS #11 support and an API to access objects in
1420 gnutls/pkcs11.h. Currently certificates and public keys can be
1421 imported from tokens, and operations can be performed on private keys.
1423 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1425 ** libgnutls: Added initial support for the nettle library. It uses
1426 the system's random generator for seeding. That is /dev/urandom in Linux,
1427 system calls in Win32 and EGD on other systems.
1429 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1430 works even when resuming a session.
1432 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1433 similar gnutls_certificate_set_server_retrieve_function() and
1434 gnutls_certificate_set_client_retrieve_function(). In addition it support
1435 PKCS #11 private keys.
1437 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1438 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1440 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1441 sizes for private keys using a human understandable scale.
1443 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1444 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1445 --pkcs11-delete-url, --pkcs11-write
1447 certtool: The --pkcs-cipher is taken into account when generating a
1448 private key. The default cipher used now is aes-128. The old behavior can
1449 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1451 certtool: Added --certificate-pubkey to print the public key of the
1454 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1455 can now accept a PKCS #11 URL in addition to a file. This will allow for
1456 example to use the Gnome-keyring trusted certificate list to verify
1457 connections using a url such as:
1458 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1539 * Version 2.10.1 (released 2010-07-25)
1541 ** libgnutls: Added support for broken certificates that indicate RSA
1544 ** gnutls-cli: Allow verification using V1 CAs.
1546 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1547 gnutls_x509_privkey_import_pkcs8() without a password, if it
1548 is unable to decode the key.
1550 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1551 a memory leak. Reported by Mads Kiilerich.
1553 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1554 issue a warning, that the output key might not be working everywhere.
1556 ** certtool: The --pkcs-cipher is taken into account when generating a
1557 private key. The default cipher used now is aes-128. The old behavior
1558 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1560 ** API and ABI modifications:
1561 No changes since last version.
1563 * Version 2.10.0 (released 2010-06-25)
1565 ** API and ABI modifications:
1566 No changes since last version.
1568 * Version 2.9.12 (released 2010-06-17)
1570 ** gnutls-cli: Make --starttls work again.
1571 Problem introduced in patch to use read() instead of fgets() committed
1574 ** API and ABI modifications:
1575 No changes since last version.
1577 * Version 2.9.11 (released 2010-06-07)
1579 ** libgnutls: Removed two APIs related to safe renegotiation.
1580 Use priority strings instead. The APIs were
1581 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1582 (Remember that we don't promise ABI stability during development
1583 series, so this doesn't cause an shared library ABI increment.)
1585 ** tests: More self testing of safe renegotiation extension.
1586 See tests/safe-renegotiation/README for more information.
1588 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1590 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1592 ** API and ABI modifications:
1593 gnutls_safe_negotiation_set_initial: REMOVED.
1594 gnutls_safe_renegotiation_set: REMOVED.
1596 * Version 2.9.10 (released 2010-04-22)
1598 ** libgnutls: Time verification extended to trusted certificate list.
1599 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1602 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1603 Based on patch by Pavan Konjarla. Adds new constant
1604 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1606 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1607 Solves the issue discussed in:
1608 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1609 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1610 Note that to allow connecting to unpatched servers the full protection
1611 is only enabled if the priority string %SAFE_RENEGOTIATION is
1612 specified. You can check whether protection is in place by querying
1613 gnutls_safe_renegotiation_status(). New error codes
1614 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1615 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1617 ** libgnutls: When checking openpgp self signature also check the signatures
1619 Ilari Liusvaara noticed and reported the issue and provided test
1622 ** libgnutls: Added cryptodev support (/dev/crypto).
1623 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1624 benchmark utility for AES. Adds new error codes
1625 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1627 ** libgnutls: Exported API to access encryption and hash algorithms.
1628 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1629 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1630 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1631 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1632 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1633 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1634 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1636 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1637 verification of certificate upon receipt rather than waiting until the
1638 end of the handshake.
1640 ** libgnutls: Don't send alerts during handshake.
1641 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1643 ** certtool: Corrected two issues that affected certificate request generation.
1644 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1645 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1646 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1647 those parameters there since other implementations don't do either and having
1648 them does not seem to offer anything (anyway you need the signer's certificate
1649 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1650 This however has the side-effect that public key IDs shown by certtool are
1651 now different than previous gnutls releases.
1652 (3) the option --pgp-certificate-info will verify self signatures
1654 ** certtool: Allow exporting of Certificate requests on DER format.
1656 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1658 ** gnutls-cli: Handle reading binary data from server.

1726 Reported by Tang Tong.
1728 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1729 ** extension and certificate verify field.
1730 This requires changes for TLS 1.2 servers and clients that use
1731 callbacks for certificate retrieval. They are now required to check
1732 with gnutls_sign_algorithm_get_requested() whether the certificate
1733 they send complies with the peer's preferences in signature

1819 Reported by Howard Chu <hyc@symas.com> in
1820 <https://savannah.gnu.org/support/?106975>.
1822 ** Fix use of deprecated types internally.
1823 Use of deprecated types in GnuTLS from now on will lead to a compile
1824 error, to prevent this from happening again.

1827 No changes since last version.
1829 * Version 2.9.3 (released 2009-08-19)
1831 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1832 The new APIs are gnutls_session_ticket_enable_client,
1833 gnutls_session_ticket_enable_server, and
1834 gnutls_session_ticket_key_generate.

1843 * Version 2.9.2 (released 2009-08-14)
1845 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1846 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1847 into 1) not printing the entire CN/SAN field value when printing a
1848 certificate and 2) cause incorrect positive matches when matching a
1849 hostname against a certificate. Some CAs apparently have poor
1850 checking of CN/SAN values and issue these (arguable invalid)
1851 certificates. Combined, this can be used by attackers to become a
1852 MITM on server-authenticated TLS sessions. The problem is mitigated
1853 since attackers needs to get one certificate per site they want to
1854 attack, and the attacker reveals his tracks by applying for a
1855 certificate at the CA. It does not apply to client authenticated TLS
1856 sessions. Research presented independently by Dan Kaminsky and Moxie
1857 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1858 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1860 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1861 The function may fail incorrectly when an earlier certificate was
1862 imported to the same gnutls_x509_crt_t structure.
1864 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1866 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.

1877 ** libgnutls: Fix PKCS#12 decryption from password.
1878 The encryption key derived from the password was incorrect for (on
1879 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1880 Tomas" <tomas.kukosa@siemens-enterprise.com> in

1884 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1885 gnutls_dh_get_peers_public_bits. Before the reported value was
1886 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in

1895 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1896 Before we required that the runtime library used the same (or more
1897 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1898 that the runtime usage is above the minimum required. Reported by
1899 Marco d'Itri <md@linux.it> via Andreas Metzler

1938 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1939 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1941 Note: As a side effect of this change, the "public key identifier"
1942 value computed for a certificate using this version of GnuTLS will be
1943 different from values computed using earlier versions of GnuTLS.
1945 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1946 ** optional SignatureAlgorithm parameter field.
1947 VeriSign rejected these CSRs. They are stricly speaking not needed
1948 since you need the signer's certificate to verify the certificate
1949 signature anyway. Reported by Wilankar Trupti

2209 No offically supported interfaces have been modified or removed. The
2210 library should be completely backwards compatible on both the source
2213 The shared library no longer exports some symbols that have never been
2214 officially supported, i.e., not mentioned in any of the header files.
2220 Normally when symbols are removed, the shared library version has to
2221 be incremented. This leads to a significant cost for everyone using
2222 the library. Because none of the above symbols have ever been
2223 intended for use by well-behaved applications, we decided that the it
2224 would be better for those applications to pay the price rather than
2225 incurring problems on the majority of applications.
2227 If it turns out that applications have been using unofficial
2228 interfaces, we will need to release a follow-on release on the v2.8
2229 branch to exports additional interfaces. However, initial testing
2230 suggests that few if any applications have been using any of the
2233 Although not a new change compared to 2.6.x, we'd like to remind you
2234 interfaces have been modified so that X.509 chain verification now
2235 also checks activation/expiration times on certificates. The affected

2243 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2245 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2246 we gave our rationale for it in earlier release notes.
2248 The following symbols have been added to the library:

2406 ** libgnutls: Fix DSA key generation.
2407 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2409 ** libgnutls: Check expiration/activation time on untrusted certificates.
2410 Merged from stable branch. Reported by Romain Francoise
2411 <romain@orebokech.com>. This changes the semantics of
2412 gnutls_x509_crt_list_verify, which in turn is used by
2413 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2414 We add two new gnutls_certificate_status_t codes for reporting the new
2415 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2416 We also add a new gnutls_certificate_verify_flags flag,
2417 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2418 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2420 ** lib: Linker version scripts reduces number of exported symbols.
2421 The linker version script now lists all exported ABIs explicitly, to
2422 avoid accidentally exporting unintended functions. Compared to
2423 before, most symbols beginning with _gnutls* are no longer exported.
2424 These functions have never been intended for use by applications, and
2425 there were no prototypes for these function in the public header
2426 files. Thus we believe it is possible to do this without incrementing
2427 the library ABI version which normally has to be done when removing an
2430 ** lib: Limit exported symbols on systems without LD linker scripts.
2431 Before all symbols were exported. Now we limit the exported symbols
2432 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2433 _gnutls*. This is a superset of the actual supported ABI, but still
2434 an improvement compared to before. This is implemented using Libtool
2435 -export-symbols-regex. It is more portable than linker version
2438 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2439 This should have been done in the last release.
2441 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2442 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2443 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2445 ** doc: Improved sections for the info manual.
2446 We now follow the advice given by the texinfo manual on which
2447 directory categories to use. In particular, libgnutls moved from the
2448 'GNU Libraries' section to the 'Software libraries' and the command
2449 line tools moved from 'Network Applications' to 'System

2460 * Version 2.7.7 (released 2009-04-20)
2462 ** libgnutls: Applied patch by Cedric Bail to add functions
2463 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2465 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

2476 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2477 It is currently only used by the core library. This will enable a new
2478 domain 'gnutls' for translations of the command line tools.
2480 ** Corrected possible memory corruption on signature verification failure.
2481 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2483 ** API and ABI modifications:
2484 gnutls_x509_crt_verify_hash: ADDED
2485 gnutls_x509_crt_get_verify_algorithm: ADDED
2487 * Version 2.7.6 (released 2009-02-27)
2489 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2490 This applies both to generating certificates and certificate requests.
2492 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2494 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2495 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2496 be used for chain verification.
2498 ** gnutls-serv: No longer disable MAC padding by default.
2499 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2501 ** gnutls-cli: Certificate information output format changed.
2502 The tool now uses libgnutls' functions to print certificate
2503 information. This avoids code duplication.
2505 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2506 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2507 They can be used to override the default certificate chain validation
2510 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2511 specify the client hello message record version. Used to overcome buggy
2512 TLS servers. Report by Martin von Gagern.
2514 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2516 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2518 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2520 ** API and ABI modifications:
2521 No changes since last version.
2523 * Version 2.7.5 (released 2009-02-06)
2525 ** libgnutls: Accept chains where intermediary certs are trusted.
2526 Before GnuTLS needed to validate the entire chain back to a
2527 self-signed certificate. GnuTLS will now stop looking when it has
2528 found an intermediary trusted certificate. The new behaviour is
2529 useful when chains, for example, contains a top-level CA, an
2530 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2531 To avoid chain validation errors due to the RSA-MD5 cert, you can
2532 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2533 The signature on trusted certificates are not checked, so the chain
2534 has a chance to validate correctly. Reported by "Douglas E. Engert"
2535 <deengert@anl.gov> in
2536 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2538 ** libgnutls: result_size in gnutls_hex_encode now holds
2539 the size of the result. Report by John Brooks <special@dereferenced.net>.
2541 ** libgnutls: gnutls_handshake when sending client hello during a
2542 rehandshake, will not offer a version number larger than the current.
2543 Reported by Tristan Hill <stan@saticed.me.uk>.
2545 ** libgnutls: Permit V1 Certificate Authorities properly.
2546 Before they were mistakenly rejected even though
2547 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2548 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2549 "Douglas E. Engert" <deengert@anl.gov> in
2550 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2552 ** API and ABI modifications:
2553 No changes since last version.
2555 * Version 2.7.4 (released 2009-01-07)
2557 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2558 This is a bugfix -- the previous attempt to do this from internal x509
2559 certificate verification procedures did not return the correct value
2560 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2561 <dkg@fifthhorseman.net> in
2562 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2563 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2564 Gillmor <dkg@fifthhorseman.net>.
2566 ** libgnutls: New interface to get key id for certificate requests.
2567 Patch from David Marín Carreño <davefx@gmail.com> in
2568 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2570 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2572 ** certtool: --verify-chain now prints results of using library verification.
2573 Earlier, certtool --verify-chain used its own validation algorithm
2574 which wasn't guaranteed to give the same result as the libgnutls
2575 internal validation algorithm. Now this command print a new final
2576 line with header 'Chain verification output:' that contains the result
2577 from using the internal verification algorithm on the same chain.
2579 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2581 ** API and ABI modifications:
2582 gnutls_x509_crq_get_key_id: ADDED.
2584 * Version 2.7.3 (released 2008-12-10)
2586 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2587 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
2588 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
2589 Andreas Metzler <ametzler@downhill.at.eu.org> in
2590 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2592 ** libgnutls: Libgcrypt initialization changed.
2593 If libgcrypt has not already been initialized, GnuTLS will now
2594 initialize libgcrypt with disabled secure memory. Initialize
2595 libgcrypt explicitly in your application if you want to enable secure
2596 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2597 allocation functions, which doesn't use secure memory, so there is no
2598 real change in behaviour.
2600 ** libgnutls: Fix memory leak in PSK authentication.
2601 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2602 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.

2755 ** libgnutls: Corrected double free on signature verification failure.
2756 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2757 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2759 ** libgnutls: Fix DSA key generation.
2760 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2761 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2762 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2764 ** libgnutls: Check expiration/activation time on untrusted certificates.
2765 Reported by Romain Francoise <romain@orebokech.com>. Before the
2766 library did not check activation/expiration times on certificates, and
2767 was documented as not doing so. We have realized that many
2768 applications that use libgnutls, including gnutls-cli, fail to perform
2769 proper checks. Implementing similar logic in all applications leads
2770 to code duplication. Hence, we decided to check whether the current
2771 time (as reported by the time function) is within the
2772 activation/expiration period of certificates when verifying untrusted
2775 This changes the semantics of gnutls_x509_crt_list_verify, which in
2776 turn is used by gnutls_certificate_verify_peers and
2777 gnutls_certificate_verify_peers2. We add two new
2778 gnutls_certificate_status_t codes for reporting the new error
2779 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2780 add a new gnutls_certificate_verify_flags flag,
2781 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2784 More details about the vulnerabilities will be posted at
2785 <http://www.gnu.org/software/gnutls/security.html>.
2787 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2788 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2789 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2791 ** tests: Fix linking of tests/openpgp/keyring self-test.
2792 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2794 ** API and ABI modifications:
2795 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2796 gnutls_certificate_verify_peers: Likewise.
2797 gnutls_certificate_verify_peers2: Likewise.
2798 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2799 GNUTLS_CERT_EXPIRED: ADDED.
2800 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2802 * Version 2.6.5 (released 2009-04-11)
2804 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2805 specify the client hello message record version. Used to overcome buggy
2806 TLS servers. Report by Martin von Gagern.
2808 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2809 Libtasn1 0.3.4 or later is required. This is to align with the
2810 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2812 ** API and ABI modifications:
2813 No changes since last version.
2815 * Version 2.6.4 (released 2009-02-06)
2817 ** libgnutls: Accept chains where intermediary certs are trusted.
2818 Before GnuTLS needed to validate the entire chain back to a
2819 self-signed certificate. GnuTLS will now stop looking when it has
2820 found an intermediary trusted certificate. The new behaviour is
2821 useful when chains, for example, contains a top-level CA, an
2822 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2823 To avoid chain validation errors due to the RSA-MD5 cert, you can
2824 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2825 The signature on trusted certificates are not checked, so the chain
2826 has a chance to validate correctly. Reported by "Douglas E. Engert"
2827 <deengert@anl.gov> in
2828 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2830 ** libgnutls: result_size in gnutls_hex_encode now holds
2831 the size of the result. Report by John Brooks <special@dereferenced.net>.
2833 ** libgnutls: gnutls_handshake when sending client hello during a
2834 rehandshake, will not offer a version number larger than the current.
2835 Reported by Tristan Hill <stan@saticed.me.uk>.
2837 ** libgnutls: Permit V1 Certificate Authorities properly.
2838 Before they were mistakenly rejected even though
2839 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2840 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2841 "Douglas E. Engert" <deengert@anl.gov> in
2842 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2844 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2845 This is a bugfix -- the previous attempt to do this from internal x509
2846 certificate verification procedures did not return the correct value
2847 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2848 <dkg@fifthhorseman.net> in
2849 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2850 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn

2872 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2873 It needs to be invoked before libgcrypt is initialized.

2884 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2885 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2886 problem for certificate chains that contained just one self-signed
2887 certificate. Reported by Michael Meskes <meskes@debian.org> in

2928 ** libgnutls-openssl: fix out of bounds access.
2929 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2930 from Thomas Viehmann <tv@beamnet.de>.
2932 ** certtool: Use inet_pton for parsing IPv6 addresses.
2934 ** Major changes compared to the v2.4 branch:
2936 *** Added API to replace and update the crypto backend.
2938 *** certtool: can add several subject alternative names via template file.
2940 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2942 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2943 either set or append alternative names. It can also handle binary structures
2944 such as IP addresses.
2946 *** libgnutls: New function to set minimum acceptable SRP bits.
2947 The function is gnutls_srp_set_prime_bits.
2949 *** libgnutls: Add interface to deal with public key and signature algorithms.
2950 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2951 gnutls_sign_list, and gnutls_sign_get_id.
2953 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2954 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2956 *** libgnutls: New API to get a string corresponding to a error symbol.
2957 The function is gnutls_strerror_name.
2959 *** libgnutls: New API to set the public parameters in a certificate request
2960 *** from a private key.
2961 The function is gnutls_x509_crq_set_key_rsa_raw.
2963 *** libgnutls: New API to set a callback to extract TLS Finished data.
2964 The function to register is gnutls_session_set_finished_function and
2965 it takes a callback of the gnutls_finished_callback_func type.
2967 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2969 *** libgnutls: New interface to register a new TLS extension handler.
2970 The new function gnutls_ext_register can be used to register handlers
2971 for specific TLS extension types. The callback functions have the new
2972 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2973 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2976 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2977 The function is gnutls_register_md5_handler. When libgcrypt is in
2978 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2981 *** API/ABI changes in GnuTLS 2.6
2982 No functions have been removed or modified. The library should be
2983 fully backwards compatible on both the source and binary level.
2985 A new header file <gnutls/crypto.h> have been added. It contains
2986 definitions related to replacing the internal crypto functionality.
2987 All definitions and the header itself is experimental but supported.
2989 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2990 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2991 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2993 The following functions have been added to libgnutls:

3109 ** libgnutls: Add interface to deal with public key and signature algorithms.
3110 The functions are called gnutls_pk_list, gnutls_pk_get_id,
3111 gnutls_sign_list, and gnutls_sign_get_id. Suggested by Sam

3146 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
3147 The code has not worked since v0.9.0 and apparently nobody has missed
3148 it, so we decided to remove the code rather than fix it. If you have
3149 old certificate chains stored in PKCS#7 format, you can convert them
3150 to a list of PEM certificates by using 'certtool --p7-info'. Reported
3151 by Christian Grothoff <christian@grothoff.org>.

3172 Reference to NIST SP 800-57 in the manual on key size recommendations.
3173 Added 'Since:' tags to new APIs for gtk-doc.
3175 ** API and ABI modifications:
3176 No changes since last version.
3178 * Version 2.5.3 (released 2008-08-14)
3180 ** libgnutls: New API to set the public parameters in a certificate request
3181 ** from a private key.
3182 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
3183 discussion with "Zach C." <fxchip@gmail.com>.
3185 ** libgnutls: New API to set a callback to extract TLS Finished data.
3186 The function to register is gnutls_session_set_finished_function and
3187 it takes a callback of the gnutls_finished_callback_func type.
3189 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
3190 Reported in <https://savannah.gnu.org/support/?106453>.
3192 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3193 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3194 names are mapped to the new names in compat.h. These mappings will
3195 likely be removed more quickly than other mappings in that file due to
3196 the namespace violation.
3198 ** libgnutlsxx: Make it build when SRP is disabled.
3200 ** doc: Add doxygen files in doc/doxygen/.
3202 ** API and ABI modifications:
3203 gnutls_x509_crq_set_key_rsa_raw: ADDED
3204 gnutls_session_set_finished_function: ADDED
3205 gnutls_finished_callback_func: ADDED

3207 GNUTLS_RANDOM_SIZE: ADDED
3208 TLS_MASTER_SIZE: DEPRECATED
3209 TLS_RANDOM_SIZE: DEPRECATED
3211 * Version 2.5.2 (released 2008-07-08)
3213 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3214 The prime and generator was swapped.
3216 ** libgnutls: New interface to register a new TLS extension handler.
3217 The new function gnutls_ext_register can be used to register handlers
3218 for specific TLS extension types. The callback functions have the new
3219 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3220 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3223 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3224 This was made possible by using the new gnutls_ext_register interface.
3225 The TLS/IA functionality has only been supported through the
3226 libgnutls-extra library, so it makes sense for the code to belong
3229 ** API and ABI modifications:
3230 gnutls_ext_recv_func: ADDED
3231 gnutls_ext_send_func: ADDED
3232 gnutls_ext_parse_type_t: ADDED
3233 gnutls_ext_register: ADDED
3235 * Version 2.5.1 (released 2008-07-02)
3239 ** API and ABI modifications:
3240 No changes since last version.
3242 * Version 2.5.0 (released 2008-07-02)
3244 ** Port fixes from v2.4.1 release, see below.
3246 ** Added API to replace and update the crypto backend.
3247 The header gnutls/crypto.h is now officially supported, and declares
3250 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3252 ** Update gnulib and translations.
3253 The gnulib gc crypto code has been removed since it was never finished
3254 and is no longer even used. An internal non-libgcrypt crypto
3255 implementation may be added in the future, but we'll decide that later
3258 ** API and ABI modifications:
3259 gnutls_crypto_bigint_register2: ADDED.
3260 gnutls_crypto_cipher_register2: ADDED.
3261 gnutls_crypto_digest_register2: ADDED.
3262 gnutls_crypto_mac_register2: ADDED.
3263 gnutls_crypto_pk_register2: ADDED.
3264 gnutls_crypto_rnd_register2: ADDED.
3265 gnutls_crypto_single_cipher_register2: ADDED.
3266 gnutls_crypto_single_digest_register2: ADDED.
3267 gnutls_crypto_single_mac_register2: ADDED.
3269 * Version 2.4.3 (released 2009-02-06)
3271 ** libgnutls: Accept chains where intermediary certs are trusted.
3272 Before GnuTLS needed to validate the entire chain back to a
3273 self-signed certificate. GnuTLS will now stop looking when it has
3274 found an intermediary trusted certificate. The new behaviour is
3275 useful when chains, for example, contains a top-level CA, an
3276 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3277 To avoid chain validation errors due to the RSA-MD5 cert, you can
3278 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3279 The signature on trusted certificates are not checked, so the chain
3280 has a chance to validate correctly. Reported by "Douglas E. Engert"
3281 <deengert@anl.gov> in
3282 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3284 ** libgnutls: Permit V1 Certificate Authorities properly.
3285 Before they were mistakenly rejected even though
3286 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3287 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3288 "Douglas E. Engert" <deengert@anl.gov> in
3289 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3291 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3292 This is a bugfix -- the previous attempt to do this from internal x509
3293 certificate verification procedures did not return the correct value
3294 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3295 <dkg@fifthhorseman.net> in
3296 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

3306 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
3307 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
3308 problem for certificate chains that contained just one self-signed
3309 certificate. Reported by Michael Meskes <meskes@debian.org> in

3378 ** API and ABI modifications:
3379 No changes since last version.
3381 * Version 2.4.0 (released 2008-06-19)
3383 ** Major changes compared to the v2.2 branch:
3385 *** The OpenPGP sub-system has been improved and now supports subkeys.
3387 *** The PSK sub-system has been improved and now supports password
3388 *** derivation and PSK identity hints.
3389 The password derivation algorithms support is documented in
3390 draft-ietf-netconf-tls-02.txt.
3392 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3393 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3394 The old parameters will continue to work for some time.
3396 *** Certtool now confirm passwords and changes permissions of private key files.
3398 *** The default handshake size limit has been increased to 48kb.
3399 It appears as if some valid handshakes are large due to sending many
3400 CA certificates. (The earlier limit was 16kb.)
3402 *** LZO compression is now disabled by default.
3403 The main reason is that LZO compression in TLS is not standardized,
3404 but license compatiblity issues with minilzo triggered us to make this
3407 *** Improvements for cross-compilation to Windows and OpenWRT.
3409 *** The look of the GTK-DOC manual has been improved.
3410 Major developer visible changes compared to the v2.2 branch:
3412 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3414 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3415 *** elements from the certificate credentials structure.
3416 Thanks to Joe Orton.
3418 *** New APIs to improve working with username/passwords and PSK.
3420 *** Names of constants to affect certificate printing changed.
3421 The constants are used for OpenPGP too, which the names didn't
3422 reflect, so the following name change has been made:
3425 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3426 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3427 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3429 The old names will be mapped to the new names for some time.
3431 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3432 *** gnutls_openpgp_privkey_get_key_id.
3433 A compatibility mapping exists to avoid breaking API backwards
3436 *** Replaced all uses of alloca with malloc and free.
3438 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3439 We have been unable to find a documented rationale for this practice.
3441 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3443 *** API/ABI changes in GnuTLS 2.4
3444 All OpenPGP related functions have been moved from libgnutls-extra to
3445 libgnutls, and several new functions have been added (see below).
3446 Before making the release, we discussed whether moving functions from
3447 libgnutls-extra to libgnutls would require us to increment the ABI
3448 version, but the general opinion was that this would not be required.
3449 All older functions continue to work the same. We are open to the
3450 possibility that this decision will lead to problem on some platform,
3451 and if it turns out that the Right Thing should have been to increment
3452 the shared library version, we would need to release an update within
3453 the 2.4.x branch that increments the shared library version.
3455 This release adds the following functions:
3457 gnutls_psk_client_get_hint
3458 gnutls_psk_set_server_credentials_hint
3459 gnutls_psk_netconf_derive_key
3461 Used to get/set the PSK identity hint, and derive PSK keys from
3462 passwords a'la netconf.
3464 gnutls_x509_dn_deinit
3465 gnutls_x509_dn_export
3466 gnutls_x509_dn_import
3469 Used to handle X.509 Certificate DN's directly.
3473 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3476 gnutls_certificate_get_x509_cas
3477 gnutls_certificate_get_x509_crls
3478 gnutls_certificate_get_openpgp_keyring
3480 Functions for direct access to credential elements.
3482 gnutls_openpgp_crt_get_auth_subkey
3483 gnutls_openpgp_crt_get_key_id

3520 gnutls_openpgp_privkey_get_subkey_revoked_status
3521 gnutls_openpgp_privkey_set_preferred_key_id
3523 New OpenPGP related functions.
3525 The function gnutls_openpgp_crt_get_key_id is the same as the old
3526 from gnutls_openpgp_crt_get_id, see above.
3528 The release also adds a new header file 'gnutls/crypto.h', however it
3529 is currently not used.

3563 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3565 ** doc/: Add psktool to info index. Some minor cleanups.
3567 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3569 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3570 The file suppresses the known libgcrypt memory leaks, so they aren't
3571 printed when you run valgrind on the gnutls self-tests. Use it as
3572 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add

3590 ** Merge gnutls_with_netconf branch.
3592 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
3593 The function is gnutls_psk_client_get_hint.

3596 The function is gnutls_psk_set_server_credentials_hint.
3598 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3599 In the client, the message is parsed and the application can use
3600 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3601 message is sent if the application has specified a PSK identity hint
3602 using gnutls_psk_set_server_credentials_hint.
3604 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3605 The function gnutls_psk_netconf_derive_key supports the PSK key
3606 derivation as specified in draft-ietf-netconf-tls-02.txt. New self

3612 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3614 *** gnutls-cli: Always support PSK modes, through a callback.
3615 The callback will derive a PSK key using Netconf algorithm. It will
3616 print the PSK identity hint to help the user.
3618 *** New PSK example client and server.
3619 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3621 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3622 The code didn't work properly on platforms where 'char' is unsigned,
3623 when you set version 0. Reported by Laurence Withers
3624 <l@lwithers.me.uk> in
3625 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
3627 ** libgnutls-openssl: added RAND_pseudo_bytes API.
3628 Patch from Robert Millan <rmh@aybabtu.com>.
3630 ** API and ABI modifications:
3631 RAND_pseudo_bytes: ADDED to libgnutls-openssl.

3634 gnutls_psk_netconf_derive_key: ADDED
3636 * Version 2.3.11 (released 2008-05-20)
3638 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3639 The flaw would result in incorrectly terminated sessions with the
3640 error "Decryption has failed" when the server sends a small packet
3641 (typically when the session is closed). Reported by Andreas Metzler
3642 <ametzler@downhill.at.eu.org> in
3643 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3645 ** Don't use gnulib headers when building C++ library.
3646 Fixes builds under Windows.
3648 ** Make umask a requirement.
3649 We don't know of any system that lacks it, even GNU CoreUtils use it
3652 ** Update gnulib files.
3653 Fixes a problem where it pulled in a replacement for memcmp under
3654 MinGW, which caused the C++ example to fail to build.
3656 ** API and ABI modifications:
3657 No changes since last version.
3659 * Version 2.3.10 (released 2008-05-19)
3661 ** Added wide wildcard hostname matching.
3662 Tiny patch by Jean-Philippe Garcia Ballester.
3664 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3665 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3666 which allowed the bugs to be reproduced and fixed easily. Patches
3667 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3668 with more details about these vulnerabilities will be added to

3671 *** [GNUTLS-SA-2008-1-1]
3672 *** libgnutls: Fix crash when sending invalid server name.
3673 The crash can be triggered remotely before authentication, which can
3674 lead to a Daniel of Service attack to disable the server. The bug
3675 cause gnutls to store more session resumption data than what was
3676 allocated for, thus overwriting unallocated memory.
3678 *** [GNUTLS-SA-2008-1-2]
3679 *** libgnutls: Fix crash when sending repeated client hellos.
3680 The crash can be triggered remotely before authentication, which can
3681 lead to a Daniel of Service attack to disable the server. The bug
3682 triggers a null-pointer dereference.
3684 *** [GNUTLS-SA-2008-1-3]
3685 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3686 The crash can be triggered remotely before authentication, which can
3687 lead to a Daniel of Service attack to disable the server. The bug
3688 cause gnutls to read memory beyond the end of the received record.
3690 ** libgnutlsxx: Updated API according to patches from Eduardo
3691 Villanueva Che (discussion at
3692 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3694 ** Use umask to restrict permissions to owner before creating a file.
3696 ** API and ABI modifications:
3697 No changes since last version.
3699 * Version 2.3.9 (released 2008-05-16)
3701 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3702 Based on report and tiny patches from
3703 <jared.jennings.ctr@eglin.af.mil>, see
3704 <https://savannah.gnu.org/support/index.php?106342>.
3706 ** libgnutls: Translation fixes.
3708 ** gnutls-cli: Fix so that PSK authentication works.
3709 Also improve manual to give example for gnutls-cli PSK authentication.
3711 ** certtool: Encrypting a private key now require a confirmed password.
3712 Before './certtool -k -8' would merely ask for a password once.
3713 Reported by Daniel 'NebuchadnezzaR' Dehennin
3714 <nebuchadnezzar@asgardr.info> see
3715 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3717 ** certtool: When writing private keys to files, change permissions of file.
3718 Now the file which the private key is saved to is chmod'ed 0600.
3719 Reported by martin f krafft <madduck@debian.org> see
3720 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3722 ** guile: Fix -fgnu89-inline test.
3724 ** Removed --enable-profile-mode.
3725 The code linked gnutls with the libfc project (Function Check) which
3726 appears to have been stalled since around 2002.
3728 ** Clean up header file checks by ./configure.
3730 ** Update of gnulib files.
3732 ** API and ABI modifications:
3733 No changes since last version.
3735 * Version 2.3.8 (released 2008-04-29)
3737 ** libgnutls: Increase default handshake packet size limit to 48kb.
3738 The old limit was 16kb and some servers send huge list of trusted CAs,
3739 thus running into the limit. FYI, applications can further increase
3740 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3741 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3742 <marc@mclemente.net> for reporting and providing test servers.
3744 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3745 Returned when the handshake data size is too large. Before
3746 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3749 ** libgnutls: Hide definitions in crypto.h.
3750 We have decided that the APIs defined in crypto.h are not stable
3751 enough for v2.4, so don't use any of those functions.
3753 ** gnutls-cli: exit when hostname doesn't match certificate.
3754 Use --insecure to avoid hostname comparison.
3756 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3757 The reason is to align terminology with OpenPGP, which doesn't use
3758 DER. The old parameters will continue to work for some time.
3760 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3762 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3764 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3765 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3766 vasprintf symbol from the libgcrypt library which caused problems.
3768 ** Update of gnulib files.
3770 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3772 ** API and ABI modifications:
3773 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3775 * Version 2.3.7 (released 2008-04-21)
3777 ** opencdk now properly sets the key usage bits into openpgp keys.
3779 ** gnutls-cli: Fix crash on TLS handshake failures.
3780 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3781 This is similar to <http://bugs.debian.org/429183>.
3783 ** certtool: with --generate-request and newly generated keys, print the key.
3785 ** Build fixes for MinGW.
3786 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3787 with -lws2_32 when needed. Use ASCII only isprint() when printing
3788 X.509 certificate information, to avoid non-ASCII but printable
3789 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3792 ** Update internal copy of libtasn1 to version 1.4.
3794 ** API and ABI modifications:
3795 No changes since last version.
3797 * Version 2.3.6 (released 2008-04-17)
3799 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3800 ** Improve documentation for gnutls_x509_crq_sign2.
3801 Based on report from "John Brooks" <aspecialj@gmail.com> in
3802 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3804 ** tests/pathlen: run diff without parameters to improve portability.
3805 Based on HPUX build hints in
3806 <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>.
3808 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3809 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3810 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3812 ** Remove all uses of gnutls_alloca/gnutls_afree.
3813 Use normal gnutls_malloc instead. One reason is increased portability
3814 to Windows, the other is that several of the uses may be unsafe
3815 because the size of data allocated could be large. Reported by
3816 Massimo Gaspari <massimo.gaspari@alice.it> in
3817 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3819 ** Build Guile code with -fgnu89-inline only when supported.
3820 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3821 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3823 ** Several GTK-DOC related fixes.
3825 ** Clean up OpenCDK related code.
3826 GnuTLS now requires its internal OpenCDK code rather than the external
3827 GPL library OpenCDK. Unfortunately, we don't have resources to
3828 maintain an external library (help welcome).
3830 ** API and ABI modifications:
3831 No changes since last version.
3833 * Version 2.3.5 (released 2008-04-14)
3835 ** Build fix for MinGW and --disable-shared.
3836 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3837 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3839 ** Document how to generate CRLs.
3840 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3842 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3844 ** Several minor fixes in the OpenPGP interface.
3845 Thanks to Daniel Kahn Gillmor.
3847 ** Fix fopen file descriptor leak in PSK server code.
3848 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3849 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3851 ** Translations files not stored directly in git to avoid merge conflicts.
3853 ** New APIs to let applications replace the RNG used.
3854 Update all RNG callers in the code to use the new interface.
3856 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3858 ** Update gnulib files.
3860 ** API and ABI modifications:
3861 gnutls_crypto_rnd_register: ADDED
3862 gnutls_rnd_level_t: ADDED
3863 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3864 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3865 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3866 gnutls_crypto_rnd_st: ADDED
3867 GNUTLS_DIG_SHA224: ADDED
3868 GNUTLS_SIGN_RSA_SHA224: ADDED
3869 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3871 * Version 2.3.4 (released 2008-03-19)
3873 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3874 They weren't renamed in the public header file.
3876 ** Added functions to register a cipher/mac/digest. This allows to
3877 override the included ones.
3879 ** Fix a bunch of compiler warnings.
3881 ** API and ABI modifications:
3882 gnutls_crypto_cipher_st: ADDED
3883 gnutls_crypto_mac_st: ADDED
3884 gnutls_crypto_digest_st: ADDED
3885 gnutls_crypto_cipher_register: ADDED
3886 gnutls_crypto_mac_register: ADDED
3887 gnutls_crypto_digest_register: ADDED
3888 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3890 * Version 2.3.3 (released 2008-03-10)
3892 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3893 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3895 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3896 We could not find any modern justification for enabling these flags by
3897 default. If you know of some platform that needs one of the flags to
3898 work properly, please let us know. (Actually introduced in v2.3.0 but
3899 not documented until now.)
3901 ** Importing many CA certificates are now considerably faster.
3902 This affect gnutls_certificate_set_x509_trust_mem,
3903 gnutls_certificate_set_x509_trust, and
3904 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3905 from O(2*n^2) to O(n). When adding 206 files containing 408
3906 certificates, using gnutls_certificate_set_x509_trust_file, the time
3907 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3908 to trigger the problem. See also
3909 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3911 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3912 ** to be explicit that it takes zero terminated data.
3914 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3916 ** Documentation fixes for the GTK-DOC manual.
3918 ** Fix compilation error related to __FUNCTION__ on some systems.
3919 Reported by Tim Mooney, see
3920 <https://savannah.gnu.org/support/?106267>.
3922 ** Updated translations.
3924 ** Update gnulib files.
3926 ** API and ABI modifications:
3927 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3928 and char* instead of void* for output buffer.
3930 * Version 2.3.2 (released 2008-02-26)
3932 ** Fix srcdir!=objdir failure in openpgpself test.
3934 ** Improved API documentation output from GTK-DOC.
3936 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3938 ** Renamed gnutls_certificate_export_x509_cas and friends.
3939 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3941 ** Internal header files cleanup.
3943 ** API and ABI modifications:
3944 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3945 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3946 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3947 gnutls_x509_dn_export: ADDED
3949 * Version 2.3.1 (released 2008-02-21)
3951 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3952 The included copy of OpenCDK has been stripped down and re-licensed
3955 ** Cipher priority string handling now handle strings that starts with NULL.
3956 Thanks to Laurence Withers <l@lwithers.me.uk>.
3958 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3960 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3963 ** Increased the default certificate verification chain limits and allowed
3964 for checks without limitation.
3966 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3967 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3968 strings and return the proper size.
3970 ** Add section 'On Record Padding' to the manual.
3971 This collects all problems related to record padding with
3972 Nokia/Sony-Ericsson phones that we know about.
3974 ** Several improvements in the OpenPGP authentication.
3975 Now subkeys can be used for authentication, according to
3976 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3978 ** certtool can print information on OpenPGP certificates and keys.
3980 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3983 ** Added gnutls_certificate_export_x509_cas and other functions to
3984 export elements from the certificate credentials structure. Based on
3985 suggestion from Joe Orton.
3988 Clarify that srp_base64 is not the same as normal base64.
3990 ** Fix non-portable use of brace expansion in makefiles.
3992 ** API and ABI modifications:
3993 gnutls_certificate_export_x509_cas: ADDED
3994 gnutls_certificate_export_x509_crls: ADDED
3995 gnutls_certificate_export_openpgp_keyring: ADDED
3996 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
3997 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
3998 gnutls_openpgp_crt_get_revoked_status: ADDED
3999 gnutls_openpgp_crt_get_subkey_count: ADDED
4000 gnutls_openpgp_crt_get_subkey_idx: ADDED
4001 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
4002 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
4003 gnutls_openpgp_crt_get_subkey_creation_time: ADDED

4036 old GNUTLS_X509_CRT_UNSIGNED_FULL.
4038 * Version 2.3.0 (released 2008-01-08)
4040 ** LZO compression is now disabled by default.
4041 The reason is that LZO compression is not standardized in TLS. If you
4042 wish to experiment with it, you will have to supply --with-lzo when
4043 invoking ./configure. The internal copy of minilzo is no longer
4044 included with GnuTLS, so you will need to install liblzo or liblzo2 on
4045 your system to have --with-lzo to be effective.
4047 ** More than one server name field is now sent to the server properly.
4048 Thanks to mark.phillips@virgin.net.
4050 ** Fixes the post_client_hello_function(). The extensions are now parsed
4051 in a callback friendly way.
4053 ** Fix for certificate selection in servers with certificate callbacks.
4055 ** Updated translations.
4057 ** Update gnulib files.
4059 ** API and ABI modifications:
4060 No changes since last version.

4064 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4065 The flaw would result in incorrectly terminated sessions with the
4066 error "Decryption has failed" when the server sends a small packet
4067 (typically when the session is closed). Reported by Andreas Metzler

4103 No changes since last version.
4105 * Version 2.2.3 (released 2008-05-06)
4107 ** Increase default handshake packet size limit to 48kb.
4108 The old limit was 16kb and some servers send huge list of trusted CAs,
4109 thus running into the limit. FYI, applications can further increase
4110 this limit using gnutls_handshake_set_max_packet_length. Thanks to
4111 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
4112 <marc@mclemente.net> for reporting and providing test servers.
4114 ** Fix compilation error related to __FUNCTION__ on some systems.
4115 Reported by Tim Mooney, see
4116 <https://savannah.gnu.org/support/?106267>.
4118 ** Documented the --priority option to gnutls-cli and gnutls-serv.
4120 ** Fix fopen file descriptor leak in PSK server code.
4121 Thanks to Laurence Withers <l@lwithers.me.uk>, see
4122 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
4124 ** Build Guile code with -fgnu89-inline only when supported.
4125 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
4126 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
4128 ** Make Camellia encryption work.
4129 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
4130 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
4132 ** API and ABI modifications:
4133 No changes since last version.
4135 * Version 2.2.2 (released 2008-02-21)
4137 ** Cipher priority string handling now handle strings that starts with NULL.
4138 Thanks to Laurence Withers <l@lwithers.me.uk>.
4140 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
4143 ** Increased the default certificate verification chain limits and allowed
4144 for checks without limitation.
4146 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
4147 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
4148 strings and return the proper size.
4150 ** API and ABI modifications:
4151 No changes since last version.
4153 * Version 2.2.1 (released 2008-01-17)
4155 ** Prevent linking libextra against previously installed libgnutls.
4156 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
4157 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
4159 ** Fixes the post_client_hello_function(). The extensions are now parsed
4160 in a callback friendly way.
4162 ** Fix for certificate selection in servers with certificate callbacks.
4164 ** API and ABI modifications:
4165 No changes since last version.
4167 * Version 2.2.0 (released 2007-12-14)
4169 ** Update internal copy of libtasn1 to version 1.2.
4171 ** Certtool --verify-chain now handle inputs larger than 64kb.
4172 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
4173 recent versions of libgcrypt. The problem was that Wine with the
4174 libgcrypt RNG generates huge amounts of debugging output.
4176 ** Translation updates.
4177 Added Dutch translation. Updated Polish and Swedish translation.
4179 ** Major changes compared to the v2.0 branch:
4181 *** SRP support aligned with newly published RFC 5054.
4183 *** OpenPGP support aligned with newly published RFC 5081.
4185 *** Support for DSA2 keys.
4187 *** Support for Camellia cipher.
4189 *** Support for Opaque PRF Input extension.
4191 *** PKCS#8 parser now handle DSA keys.
4193 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4194 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4195 versions, such as 2.01 which is included with GnuTLS, is available
4196 under GPLv2 or later. If this incompatibility causes problems, we
4197 recommend you to disable LZO using --without-lzo. LZO compression is
4198 not a standard TLS compression algorithm, so the impact should be
4201 *** Functions for disabling record protocol padding.
4202 Works around bugs on Nokia/Ericsson phones.
4204 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4205 Priorities like "COMPAT" also enables other work arounds, such as
4208 *** Other minor improvements and bug fixes.
4210 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4211 To adapt to changes in the TLS extension specifications for OpenPGP
4212 and SRP, the GnuTLS API had to be modified. This means breaking the
4213 API and ABI backwards compatibility. That is something we try to
4214 avoid unless it is necessary. We decided to also remove the already
4215 deprecated stub functions for X.509 to XML conversion and TLS
4216 authorization (see below) when we had the opportunity.
4218 Generally, most applications does not need to be modified. Just
4219 re-compile them against the latest GnuTLS release, and it should work
4222 Applications that use the OpenPGP or SRP features needs to be
4223 modified. Below is a list of the modified APIs and discussion of what
4224 the minimal things you need to modify in your application to make it
4225 work with GnuTLS 2.2.
4227 Note that GnuTLS 2.2 also introduces new APIs -- such as
4228 gnutls_set_priority() that is superior to
4229 gnutls_set_default_priority() -- that you may want to start using.
4230 However, using those new APIs is not required to use GnuTLS 2.2 since
4231 the old functions continue are still supported. This text only
4232 discuss what you minimally have to modify.
4234 *** XML related changes
4235 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4236 deprecated and only returned an error code since GnuTLS version
4237 1.2.11. Nobody has complained, so users doesn't seem to miss the
4238 functionality. We don't know of any other library to convert X.509
4239 certificates into XML format, but we decided (long ago) that GnuTLS
4240 isn't the right place for this kind of functionality. If you want
4241 help to find some other library to use here, please explain and
4242 discuss your use case on help-gnutls@gnu.org.
4244 *** TLS Authorization related changes
4245 Everything related to TLS authorizations have been removed, they were
4246 only stub functions that returned an error code:
4248 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4249 gnutls_authz_data_format_type_t
4250 gnutls_authz_recv_callback_func
4251 gnutls_authz_send_callback_func
4253 gnutls_authz_send_x509_attr_cert
4254 gnutls_authz_send_saml_assertion
4255 gnutls_authz_send_x509_attr_cert_url
4256 gnutls_authz_send_saml_assertion_url
4258 *** SRP related changes
4259 The callback gnutls_srp_client_credentials_function has a new
4260 prototype, and its semantic has changed. You need to rewrite the
4261 callback, see the updated function documentation and SRP example code
4262 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4265 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4266 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4267 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4268 used. There are #define's to map the old names to the new. You may
4269 run into problems if you have a switch-case with cases for both SRP
4270 alerts, since they are now mapped to the same value. The solution is
4271 to drop the SRP alerts from such switch cases, as they are now
4272 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4274 *** OpenPGP related changes
4275 The function `gnutls_certificate_set_openpgp_keyserver' have been
4276 removed. There is no replacement functionality inside GnuTLS. If you
4277 need keyserver functionality, consider using the GnuPG tools.
4279 All functions, types, and error codes related to OpenPGP trustdb
4280 format have been removed. The trustdb format is a non-standard
4281 GnuPG-specific format, and we recommend you to use key rings instead.
4282 The following have been removed:
4284 gnutls_certificate_set_openpgp_trustdb
4285 gnutls_openpgp_trustdb_init
4286 gnutls_openpgp_trustdb_deinit
4287 gnutls_openpgp_trustdb_import
4288 gnutls_openpgp_key_verify_trustdb
4289 gnutls_openpgp_trustdb_t
4290 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
4292 The following functions has an added parameter of the (new) type
4293 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4294 (binary or base64). The functions are:
4295 gnutls_certificate_set_openpgp_key_file
4296 gnutls_certificate_set_openpgp_key_mem
4297 gnutls_certificate_set_openpgp_keyring_mem
4298 gnutls_certificate_set_openpgp_keyring_file
4300 To improve terminology and align with the X.509 interface, some
4301 functions have been renamed. Compatibility mappings exists. The old
4302 and new names of the affected functions and types are:
4305 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4306 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
4307 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
4308 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
4309 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
4310 gnutls_openpgp_key_init gnutls_openpgp_crt_init
4311 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
4312 gnutls_openpgp_key_import gnutls_openpgp_crt_import
4313 gnutls_openpgp_key_export gnutls_openpgp_crt_export
4314 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
4315 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
4316 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
4317 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
4318 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
4319 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
4320 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
4321 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
4322 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
4323 gnutls_openpgp_send_key gnutls_openpgp_send_cert
4325 ** API and ABI modifications:
4326 No changes since last version.
4328 * Version 2.1.8 (released 2007-12-10)
4330 ** The GPL version has been changed from version 2 to version 3.
4331 This affects the self-tests, command-line tools, the libgnutls-extra
4332 library, the relevant guile parts, and the build environment.
4334 ** Added gnutls_x509_crt_get_subject_alt_name2().
4336 ** Corrected a segfault when setting an empty gnutls_priority_t
4337 at gnutls_priority_set().
4339 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
4340 Fixes a problem with spurious -L/usr/lib additions.
4342 ** API and ABI modifications:
4343 gnutls_x509_crt_get_subject_alt_name2: ADD.
4345 * Version 2.1.7 (released 2007-11-29)
4347 ** PKCS #8 parser can now encode/decode DSA keys.
4349 ** Updated gnutls_set_default_priority2() now renamed to
4350 gnutls_priority_set() and gnutls_priority_set_direct() which
4351 accept a string to indicate preferences of ciphersuite parameters.
4353 ** gnutls-cli and gnutls-serv now have a --priority option to set
4354 the priority string.
4356 ** The gnutls_*_convert_priority() functions were deprecated by
4357 the gnutls_priority_set() and gnutls_priority_set_direct().
4359 ** Internal copy of OpenCDK upgraded to version 0.6.6.

4392 * Version 2.1.6 (released 2007-11-15)
4394 ** Corrected bug in decompression of expanded compression data.
4396 ** Added the --to-p8 option to certtool to convert private keys
4399 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4401 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4404 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4405 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4406 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4407 documented. This caused some problems (e.g., debian #450854). To
4408 avoid backwards compatibility problems, this release revert this
4409 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4410 done in GnuTLS 2.0.x and earlier, and add a new error code
4411 GNUTLS_E_UNKNOWN_ALGORITHM.
4413 ** Fixes several gtk-doc warnings.
4415 ** API and ABI modifications:
4416 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4417 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4418 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4420 * Version 2.1.5 (released 2007-11-01)
4422 ** Fix PKCS#3 parameter export problem.
4424 ** Improve certtool queries, they now print the default value.
4428 ** Update gnulib files.
4430 ** API and ABI modifications:
4431 No changes since last version.
4433 * Version 2.1.4 (released 2007-10-27)
4435 ** Added the --v1 option to certtool, to allow generating X.509
4436 version 1 certificates.
4438 ** certtool: Add option --disable-quick-random to enable the old behaviour
4439 of using /dev/random to generate keys.
4441 ** Added priority functions that accept strings.
4443 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4444 priorities preferences.
4446 ** Added gnutls_record_disable_padding() to allow servers talking to
4447 buggy clients that complain if the TLS 1.0 record protocol padding is
4450 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4451 all supported compatibility options (like disabling padding).
4453 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4454 the format. This makes the interface consistent with the x509 functions.
4456 ** Internal copy of OpenCDK upgraded to version 0.6.5.

4498 This technique may be patented in the future, and it is not of crucial
4499 importance for the Internet community. After deliberation we have
4500 concluded that the best thing we can do in this situation is to
4501 encourage society not to adopt this technique. We have decided to
4502 lead the way with our own actions.

4522 * Version 2.1.2 (released 2007-10-14)
4524 ** Removed all the trustdb code from openpgp authentication.
4525 We now use only the well-specified keyrings.
4527 ** The 256 bit ciphers are not enabled in the default priorities.
4529 ** Added support for DSA2 using libgcrypt 1.3.0.

4566 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4567 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4568 compiled with Camellia support. See the libgcrypt documentation on
4569 how to enable it. Unconditionally disable it using the configure

4599 * Version 2.0.3 (released 2007-11-10)
4601 ** This version backports several fixes from the 2.1.x branch.
4603 ** Fixed PKCS #3 parameter export.
4605 ** Added gnutls_record_disable_padding() to allow servers talking to
4606 buggy clients that complain if the TLS 1.0 record protocol padding is
4609 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4610 all supported compatibility options (like disabling padding).
4612 ** Corrected bug which did not allow a server to run without supporting
4615 ** API and ABI modifications:
4616 gnutls_session_enable_compatibility_mode: ADDED
4617 gnutls_record_disable_padding: ADDED
4619 * Version 2.0.2 (released 2007-10-17)
4621 ** TLS authorization support removed.
4622 This technique may be patented in the future, and it is not of crucial
4623 importance for the Internet community. After deliberation we have
4624 concluded that the best thing we can do in this situation is to
4625 encourage society not to adopt this technique. We have decided to
4626 lead the way with our own actions.
4628 ** certtool: Fixed data corruption when using --outder.
4630 ** Fix configure-time Guile detection.
4632 ** API and ABI modifications:
4633 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4634 gnutls_supplemental_data_format_type_t enum type becomes empty.
4636 * Version 2.0.1 (released 2007-09-20)
4638 ** New directory doc/credentials/ with test credentials.
4639 This collects the test credentials from the web page and from src/.
4640 The script gnutls-http-serv has also been moved to that directory.
4642 ** Update SRP extension type and cipher suite with official IANA values.
4643 This breaks backwards compatibility with SRP in older versions of
4644 GnuTLS, but this is intentional to speed up the adoption of the
4645 official values. The old values we used were incorrect.
4647 ** Guile: Fix `x509-certificate-dn-oid'
4649 ** API and ABI modifications:
4650 No changes since last version.
4652 * Version 2.0.0 (released 2007-09-04)
4654 ** Included copy of Libtasn1 upgraded to version 1.1.
4656 ** Disable building of some examples if anonymous ciphers are disabled.
4658 ** Don't build examples for disabled features.
4660 ** API and ABI modifications:
4661 No changes since last version.
4663 * Version 1.7.19 (released 2007-08-27)
4665 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4666 This solves connection problems in mutt, see
4667 <http://bugs.debian.org/439640>.
4669 ** Update gnulib files.
4670 In particular, the getpass module -- with its dependencies on getline,
4671 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4672 library) directory to the gl/ directory (only used by the command line
4673 tools). The reason is that getpass is now only used by the
4674 command-line tools, and reducing the number of gnulib modules linked
4675 to the core library helps portability and reduces size.
4679 ** Disable building of PGP examples if PGP is disabled.
4681 ** Included copy of OpenCDK upgraded to version 0.6.4.
4683 ** API and ABI modifications:
4684 No changes since last version.
4686 * Version 1.7.18 (released 2007-08-16)
4688 ** Install images for the info manual.
4689 This has a side effect of renaming the images. See
4690 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4691 discussions on the approach chosen.
4693 ** Fix pointer mix to variables of different size.
4694 Patch extracted from
4695 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4697 ** Fix warnings during build.
4698 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4700 ** API and ABI modifications:
4701 No changes since last version.
4703 * Version 1.7.17 (released 2007-08-15)
4705 ** New functions to perform external signing.
4706 Set the signing callback function (of the gnutls_sign_func prototype)
4707 using the gnutls_sign_callback_set function. In the callback, you may
4708 find the new functions gnutls_x509_privkey_sign_hash and
4709 gnutls_openpgp_privkey_sign_hash useful. A new function
4710 gnutls_sign_callback_get is also added, to retrieve the function
4711 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4712 comments and testing.
4714 ** New self test of client and server authenticated X.509 TLS sessions.
4715 See tests/x509self.c and tests/x509signself.c. The latter also tests
4716 the new external signing callback interface.
4718 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4719 These two actually describe the outer limits of a range of error codes
4720 reserved to the application. All of the errors are treated as fatal
4721 by the library (it has to since it doesn't know the semantics of the
4722 error codes). This can be useful in callbacks, to signal some
4723 application-specific error condition, which will usually eventually
4724 cause some gnutls API to return the same error code as the callback,
4725 which then can be inspected by the application. Note that error codes
4728 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4729 The RFC is not released yet, and we're approaching a major release so
4730 let's not enable it just yet.
4732 ** Fix namespace so that gnutls_*_t is used consistently.
4733 Before, many places in the GnuTLS code used the old deprecated type
4734 names without the '_t' suffix.
4736 ** Build fixes for Guile code.
4737 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4739 ** More documentation fixes.
4740 In particular, the section headings were modified for casing. By
4741 Ludovic Courtes <ludovic.courtes@laas.fr>.
4743 ** Updated Polish and Swedish translations.
4744 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4745 <po@danielnylander.se>.
4747 ** API and ABI modifications:
4748 gnutls_sign_func: ADD, new type for sign callback.
4749 gnutls_sign_callback_set: ADD, new function to set sign callback.
4750 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4751 gnutls_x509_privkey_sign_hash,
4752 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4753 GNUTLS_E_APPLICATION_ERROR_MIN,
4754 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4756 * Version 1.7.16 (released 2007-08-07)
4758 ** Fix sanity checks and return values in certificate selection.
4759 In some cases, GnuTLS omitted to report suitable error codes when no
4760 suitable certificate was found.
4762 ** Fix gnutls-cli starttls EOF on Mac OS X.
4763 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4765 ** Documentation fixes.
4766 In particular, the section headings were modified for casing. By
4767 Ludovic Courtes <ludovic.courtes@laas.fr>.
4769 ** Update gnulib files.
4771 ** API and ABI modifications:
4772 No changes since last version.
4774 * Version 1.7.15 (released 2007-07-02)
4776 ** Fix self-tests key-id under mingw32.
4778 ** Test that the Guile header files are recent enough to work.
4779 Before we just tested that the command line tool 'guile' was recent
4780 enough, which may not be sufficient if you still have an old
4781 libguile.h header installed.
4783 ** Guile bindings are now installed under $prefix by default.
4784 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4785 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4786 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4787 The default, --with-guile-site-dir, will install the Guile bindings
4788 under $datadir/guile/site. There is a new section 'Guile
4789 Preparations' in the manual that discuss these issues.
4791 ** Fix run-time library path ordering in linking the Guile bindings.
4793 ** Improved manual on downloading, installing, getting help, bug reports etc.
4794 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4796 ** Add Malay message translations.
4797 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
4799 ** API and ABI modifications:
4800 No changes since last version.
4802 * Version 1.7.14 (released 2007-06-26)
4804 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
4805 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4807 ** Fix memory leak during DSA signature verification.
4808 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4810 ** Fix crash in gnutls-cli when TLS handshake fails.
4811 Reported by Marc Haber <mh+debian-bugs@zugschlus.de> and Andreas
4812 Metzler <ametzler@downhill.at.eu.org> via Debian BTS #429183, see

4816 Patch from Timo Schulz <twoaday@freakmail.de> and Ludovic Courtès
4817 <ludovic.courtes@laas.fr>.
4819 ** Fix off-by-one in TLS 1.2 handshake.
4820 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4822 ** Minor Guile binding self-test cleanup.
4823 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4825 ** Update gnulib files.
4827 ** API and ABI modifications:
4828 No changes since last version.
4830 * Version 1.7.13 (released 2007-06-11)
4832 ** OpenCDK copy updated to version 0.6.3.
4834 ** Build fixes for GnuTLS Guile bindings.
4835 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4837 ** Build fix for GTK-DOC manual.
4839 ** Update gnulib files.
4841 ** API and ABI modifications:
4842 No changes since last version.
4844 * Version 1.7.12 (released 2007-06-08)
4846 ** Guile bindings for GnuTLS have been included.
4847 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
4848 new chapter 'Guile Bindings' in the manual.
4850 ** Have PKCS8 parser return better error codes.
4851 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4852 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4853 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4855 ** Fix mem leak for sessions with client authentication via certificates.
4856 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4857 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4860 Reported by Dennis Vshivkov <walrus@amur.ru>, see
4861 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
4862 self-test tests/parse_ca.c to test regressions.
4864 ** Fix build failures related to missing images in manual.
4865 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4867 ** Update gnulib files.
4869 ** API and ABI modifications:
4870 No changes since last version.
4872 * Version 1.7.11 (released 2007-05-26)
4874 ** Include opencdk.h in the release.
4875 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4877 ** API and ABI modifications:
4878 No changes since last version.
4880 * Version 1.7.10 (released 2007-05-25)
4882 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4883 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4885 ** Update of gnulib files.
4887 ** GnuTLS is now developed in GIT instead of CVS.
4888 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4890 ** API and ABI modifications:
4891 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4892 gnutls_x509_crt_get_raw_dn: ADD.
4894 * Version 1.7.9 (released 2007-05-12)
4896 ** X.509 certificates are preferred over OpenPGP keys.
4897 This is a change in the semantics of gnutls_set_default_priority.
4899 ** The included copy of OpenCDK has been updated to 0.6.1.
4900 There has been some API changes in OpenCDK, and the GnuTLS layer have
4901 been modified as well. Note that while there are API/ABI incompatible
4902 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4903 its API/ABI have not changed. From this version on, GnuTLS requires
4904 OpenCDK 0.6.0 or later.
4906 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4908 ** Change certtool's default serial number from 0 to a time-based value.
4910 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4911 Before, we remove the parameters field, which resulted in a slightly
4912 different DER encoding which in turn caused signature verification
4913 failures of GnuTLS-generated RSA certificates in some other
4914 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4915 you read, this may or may not be correct, but our new behaviour appear
4916 to be consistent with other widely used implementations.
4918 ** Fix mem leaks in gnutls_x509_crt_print.
4920 ** API and ABI modifications:
4921 No changes since last version.
4923 * Version 1.7.8 (released 2007-04-16)
4925 ** Added examples for the authorization extension.
4926 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4928 ** The examples only use gnutls_set_default_priority().
4929 The exception is when DH_ANON is needed.
4931 ** Improve gnutls_set_default_priority() priorities.
4932 The new approach is for it to try and negotiate all secure and
4933 standard mechanisms available. Currently, DH_ANON ciphersuites and
4934 LZO compressions are not enabled by default, because they are,
4935 respectively, insecure and non-standardized. Note that TLS 1.2 will
4936 not be enabled by default in non-experimental release until it has
4937 been approved by the IETF.
4939 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4940 This means that to get DH_ANON and LZO compression, you'll need to
4941 specify that manually using '--kx anon' or '--comp lzo'.
4943 ** Minor fixes to the human display format of X.509 certificates.
4945 ** New APIs to extract Distinguished Name's from X.509 certificates.
4946 Based on patch from Howard Chu <hyc@symas.com>.
4948 ** Improved library searching for opencdk.
4949 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4950 The deprecated opencdk.m4 is no longer used.
4952 ** New APIs to list supported algorithms in the library.
4953 The APIs are gnutls_cipher_list, gnutls_mac_list,
4954 gnutls_compression_list, gnutls_protocol_list,
4955 gnutls_certificate_type_list, gnutls_kx_list, and
4956 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4958 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4960 ** New configure option --disable-tls-authorization to disable tls-authz.
4962 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4963 The last parameter was renamed from 'flags' to 'format' and the type
4964 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4965 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4968 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4969 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4971 ** API and ABI modifications:
4972 gnutls_x509_dn_t: ADD.
4973 gnutls_x509_ava_st: ADD.
4974 gnutls_x509_crt_get_subject,
4975 gnutls_x509_crt_get_issuer: ADD.
4976 gnutls_x509_dn_get_rdn_ava: ADD.
4977 gnutls_cipher_list: ADD.
4978 gnutls_mac_list: ADD.
4979 gnutls_compression_list: ADD.
4980 gnutls_protocol_list: ADD.
4981 gnutls_certificate_type_list: ADD.
4982 gnutls_kx_list: ADD.
4983 gnutls_cipher_suite_info: ADD.
4985 * Version 1.7.7 (released 2007-02-22)
4987 ** Support for supplemental handshake messages and authorization data.
4988 Supplemental data is described in RFC 4680 and the authorization
4989 extensions in draft-housley-tls-authz-extns-07.
4991 ** Support for authorization data in gnutls-cli and gnutls-serv.
4992 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4994 ** Fix for gnutls_x509_crt_check_hostname.
4995 Before it would have reported that the certificate matched a hostname
4996 when it did not have any dNSName or any CN field. Report and tiny
4997 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4999 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
5000 Tests regressions of the bug, and several other features.
5002 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
5003 Before there were no support for iPAddress SAN's during comparison.
5005 ** New API to print information about CRL's.
5006 The function is gnutls_x509_crl_print.
5008 ** New API to extract signature value from CRL's.
5009 The function is gnutls_x509_crl_get_signature.
5011 ** Support for directoryName Subject Alternative Name's.
5012 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
5013 string in the provided buffer.
5015 ** Internal improvements to certtool.
5016 It uses gnutls_x509_crl_print to print CRL information. It uses some
5017 more gnulib modules to simplify error handling.
5019 ** API and ABI modifications:
5020 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
5021 gnutls_supplemental_data_format_type_t: ADD.
5022 gnutls_authz_data_format_type_t: ADD.
5023 gnutls_supplemental_get_name: ADD.
5024 gnutls_authz_recv_callback_func,
5025 gnutls_authz_send_callback_func: ADD, callback prototypes.
5026 gnutls_authz_enable: ADD.
5027 gnutls_authz_send_x509_attr_cert,
5028 gnutls_authz_send_saml_assertion,
5029 gnutls_authz_send_x509_attr_cert_url,
5030 gnutls_authz_send_saml_assertion_url: ADD.
5031 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
5032 gnutls_x509_crl_print: ADD.
5033 gnutls_x509_crl_get_signature: ADD.
5035 * Version 1.7.6 (released 2007-02-12)
5037 ** Support for 'otherName' Subject Alternative Names.
5038 The existing API gnutls_x509_crt_get_subject_alt_name may now return
5039 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
5040 To find out the otherName OID (necessary for proper parsing of the
5041 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
5042 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
5043 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
5044 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
5046 ** Certtool can print otherName SAN values for certificates.
5047 For known otherName OIDs (currently only id-on-xmppAddr as defined by
5048 RFC 3920), it will also print the name.
5050 ** Fix TLS 1.2 RSA signing in servers.
5051 Before it used the old-style MD5+SHA1 signature, but the TLS
5052 signatures should be normal PKCS#1 signatures. FYI, we use and
5053 require that DigestInfo parameters are present and NULL for TLS 1.2.
5055 ** Add APIs to access X.509 extensions sequentially.
5056 The existing APIs gnutls_x509_crt_get_extension_oid() and
5057 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
5058 inspect the extensions in the order defined by the certificate.
5060 ** Add API to extract signature value from X.509 certificates.
5061 The function is gnutls_x509_crt_get_signature.
5063 ** Fix crash when generating proxy certificates in batch mode.
5064 If you don't specify a proxy policy in batch mode, it will use
5067 ** Add API to print information about X.509 certificates.
5068 The function is gnutls_x509_crt_print.
5070 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
5071 One consequence of this is that the output syntax has changed
5072 slightly. Some more fields are printed.
5076 ** API and ABI modifications:
5077 gnutls_x509_crt_print: ADD
5078 gnutls_certificate_print_formats_t: ADD, new enum.
5079 gnutls_x509_crt_get_signature: ADD.
5080 gnutls_x509_crt_get_extension_data: ADD.
5081 gnutls_x509_crt_get_extension_info: ADD.
5082 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
5083 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
5084 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
5086 * Version 1.7.5 (released 2007-02-06)
5088 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
5091 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
5093 ** Fix --list output for gnutls-cli and gnutls-serv.
5094 Mention TLS1.2, SHA512 etc.
5096 ** Manual contains new section on setting up a test HTTP server.
5097 A server set up following those descriptions are available online via
5098 <http://www.gnutls.org/server.html>.
5100 ** Update of gnulib files.
5102 ** API and ABI modifications:
5103 No changes since last version.
5105 * Version 1.7.4 (released 2007-02-05)
5107 ** Support for RSA signing using SHA-256/384/512.
5108 A new self test "sha2" tries to build a long X.509 certificate chain
5109 testing all new hashes.
5111 ** The gnutls-serv tool now use static DH parameters if none are supplied.
5113 ** Discuss proxy certificates in the manual.
5115 ** Improve bibliographical citations in the manual.
5117 ** Update of gnulib files.
5119 ** Fix certtool template handling of pathLenConstraints.
5120 It now defaults to -1 instead of 0, which causes the field to be
5121 missing unless the template specify it.
5123 ** API and ABI modifications:
5126 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
5129 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
5130 GNUTLS_SIGN_RSA_SHA256,
5131 GNUTLS_SIGN_RSA_SHA384,
5132 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
5134 * Version 1.7.3 (released 2007-02-01)
5136 ** New option to certtool: --generate-proxy.
5137 This will generate a Proxy Certificate from an end entity certificate.
5138 Proxy Certificates are documented in RFC 3820. You will need to
5139 specify the proxy certificate's private key with --load-privkey, the
5140 user certificate with --load-certificate and the private key used to
5141 sign the new proxy certificate with --load-ca-privkey. Certtool will
5142 query for proxy path length and the policy language OID. Currently
5143 only OIDs that have an empty policy are supported (which includes the
5144 two OIDs defined by RFC 3820).
5146 ** Certtool --certificate-info now prints information for Proxy Certificates.
5147 Before the proxy extension was just printed as DER encoded data.
5149 ** New APIs to set proxy subject names and get/set proxy cert extension.
5151 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
5153 ** Added self-test to test for regressions of pathLenConstraint bug.
5154 Incidentally, this also test (some) other regressions or changes in
5155 the output from certtool --certificate-info.
5157 ** When certtool generates CA certificates, pressing enter on the path
5158 ** length constraint query will now remove the field.
5159 Before it set the path length constraint to 0, which is a rather poor
5162 ** Certtool now print times in UTC when printing certificate/CRL info.
5164 ** Add better fix to work around C++ compiler bug on Mac OS X.
5165 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
5167 ** Fix import of ASCII armored OpenPGP keys.
5168 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
5170 ** Update of gnulib files.
5172 ** API and ABI modifications:
5173 gnutls_x509_crt_set_proxy_dn: ADD.
5174 gnutls_x509_crt_set_proxy: ADD.
5175 gnutls_x509_crt_get_proxy: ADD.
5177 * Version 1.7.2 (released 2007-01-14)
5179 ** Certtool now print the value of the pathLenConstraints field for certs.
5181 ** Certtool now query for path length constraints when generating CA certs.
5182 For batch uses, the certtool configuration name is "path_len".
5183 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5185 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
5186 The new functions gnutls_x509_crt_get_basic_constraints and
5187 gnutls_x509_crt_set_basic_constraints provide a superset of the
5188 functionality in the old gnutls_x509_crt_get_ca_status and
5189 gnutls_x509_crt_set_ca_status (respectively), but the old functions
5190 will continue to be supported.
5192 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5193 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5194 OpenCDK release with this patch will be made soon, which should bump
5195 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5197 ** Certtool --to-p12 can now store more than one certificate in the blob.
5198 Before it could only store one certificate, but now it will read and
5199 store as many certificate there are from the --load-certificate file.
5200 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5202 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5203 In particular, the OpenPGP function variables are no longer part of
5204 the exported libgnutls interface, and no header files from
5205 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5206 were never intended for non-internal purposes, and thus this does not
5207 imply a change in the external API/ABI.
5209 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5210 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5212 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5213 Before these parameters were set to make GnuTLS build under mingw32,
5214 however, they appear to no longer be necessary.
5216 ** A minor fix to the C++ library to make it build.
5217 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5219 ** Update of gnulib files.
5221 ** API and ABI modifications:
5222 gnutls_x509_crt_get_basic_constraints: ADD.
5223 gnutls_x509_crt_set_basic_constraints: ADD.
5224 cdk_pubkey_to_sexp: ADD (in opencdk).
5225 cdk_seckey_to_sexp: ADD (in opencdk).
5227 * Version 1.7.1 (released 2006-12-28)
5229 ** TLS 1.2 server side fix.
5230 The Certificate Request sent did not contain the list of supported
5231 hashes field, thus violating the protocol. It will now contain an
5232 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5234 ** TLS 1.2 DSA signature verification fix.
5235 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5237 ** Fix the list of trusted CAs that server's send to clients.
5238 Before, the list contained issuer DN's instead of subject DN's of the
5239 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5241 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5242 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5243 function. Reported by Max Kellermann <max@duempel.org>.
5245 ** Encode UID fields in DN's as DirectoryString.
5246 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5247 incorrect, it should have used DirectoryString. Now it will use
5248 DirectoryString for the UID field, but for backwards compatibility it
5249 will also accept IA5String UID's. Reported by Max Kellermann
5252 ** Improve out-of-sourcedir builds from CVS.
5253 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5255 ** Bootstrap tools changed.
5256 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5257 building GnuTLS from CVS. Libtool 1.5.22 is used.
5259 ** Fixed a syntax error in lib/gnutls.asn.
5260 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5262 ** Added German translation of GnuTLS messages.
5264 ** Update of gnulib files.
5266 ** API and ABI modifications:
5267 No changes since last version.
5269 * Version 1.7.0 (released 2006-11-29)
5271 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5272 The details is that the protocol priority set by
5273 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5274 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5276 ** Preliminary support for TLS 1.2.
5277 The client has been successfully tested against
5278 https://www.mikestoolbox.org:4433/.
5280 ** Anonself test now print a lot of debugging info, including TLS version.
5282 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5284 ** Update of gnulib files.
5286 ** API and ABI modifications:
5287 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5289 *** Pulled up from stable 1.6.x branch:
5291 ** Fix ./configure failure with non-GCC compilers.
5292 This fixes the following error message:
5293 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5294 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5296 * Version 1.6.3 (released 2007-05-26)
5298 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5299 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5300 from the 1.7.x branch, see
5301 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5303 ** Have PKCS8 parser return better error codes.
5304 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
5305 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
5306 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5308 ** Fix mem leak for sessions with client authentication via certificates.
5309 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5310 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5312 ** Fix building of 'tlsia' self test.
5313 Earlier some gcc are known to build tlsia linking to
5314 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5315 the build directory, even though command line parameters look OK.
5316 Changing order of some parameters fixes it.
5318 ** API and ABI modifications:
5319 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5320 gnutls_x509_crt_get_raw_dn: ADD.
5322 * Version 1.6.2 (released 2007-04-18)
5324 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5325 Before, we remove the parameters field, which resulted in a slightly
5326 different DER encoding which in turn caused signature verification
5327 failures of GnuTLS-generated RSA certificates in some other
5328 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5329 you read, this may or may not be correct, but our new behaviour appear
5330 to be consistent with other widely used implementations.
5332 ** Regenerate the PKIX ASN.1 syntax tree.
5333 For some reason, after changing the ASN.1 type of ldap-UID in the last
5334 release, the generated C file built from the ASN.1 schema was not
5335 refreshed. This can cause problems when reading/writing UID
5336 components inside X.500 Distinguished Names. Reported by devel
5337 <dev001@pas-world.com>.
5339 ** Updated translations.
5341 ** API and ABI modifications:
5342 No changes since last version.
5344 * Version 1.6.1 (released 2006-12-28)
5346 ** Fix the list of trusted CAs that server's send to clients.
5347 Before, the list contained issuer DN's instead of subject DN's of the
5348 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5350 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5351 Reported by Max Kellermann <max@duempel.org>.
5353 ** Encode UID fields in DN's as DirectoryString.
5354 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5355 incorrect, it should have used DirectoryString. Now it will use
5356 DirectoryString for the UID field, but for backwards compatibility it
5357 will also accept IA5String UID's. Reported by Max Kellermann
5360 ** Fix ./configure failure with non-GCC compilers.
5361 This fixes the following error message:
5362 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5363 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5365 ** API and ABI modifications:
5366 No changes since last version.
5368 * Version 1.6.0 (released 2006-11-17)
5370 ** No changes since 1.5.5.
5371 The major changes compared to the 1.4.x branch are:
5373 *** A GnuTLS C++ library is part of the official distribution.
5374 Currently there are no examples or documentation, but hopefully this
5375 will change. See gnutlsxx.h for the API.
5377 *** Windows is a supported platform.
5378 There are, however, two know bugs. One is related to select() in
5379 command line tools (not, nota bene, in the library), the other is a
5380 problem with libgcrypt that causes delays. Help is needed to resolve
5381 those issues, so we feel we can't delay the release because of this.
5383 *** New APIs for custom push/pull function error reporting.
5384 The new APIs are gnutls_transport_set_errno and
5385 gnutls_transport_set_global_errno. See the release notes for version
5386 1.5.4 for more information.
5388 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5390 * Version 1.5.5 (released 2006-11-16)
5392 ** Correctly bump shared library version after adding new APIs.
5393 This was forgotten in the last release.
5395 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5396 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5398 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5400 ** Update of gnulib files.
5402 ** API and ABI modifications:
5403 No changes since last version.
5405 * Version 1.5.4 (released 2006-11-07)
5407 ** New API functions to set errno in push/pull functions.
5408 Under Windows, setting the errno variable in a push/pull replacement
5409 may end up setting the wrong errno variable, and GnuTLS send/recv
5410 functions become confused about the real errno returned from a failed
5411 push/pull function. Therefor, we have added two APIs to set the errno
5412 variable used by GnuTLS. The APIs can also help to keep things
5413 thread-safe, by avoiding potentially global variables. Typically,
5414 instead of setting errno in your push/pull function, you will call one
5415 of these functions. It is recommended to use
5416 gnutls_transport_set_errno, but if you don't have the session variable
5417 easily accessible in the push/pull replacement function, you can use
5418 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5419 <tim.kosse@filezilla-project.org>.
5421 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5422 void gnutls_transport_set_global_errno (int err);
5424 ** When calling `recv' or `send' Windows errors are handled properly.
5425 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5426 WSAGetLastError to access the error condition instead.
5428 ** Several OpenPGP API fixes.
5429 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5430 important fix is to change the return value of
5431 gnutls_openpgp_privkey_get_pk_algorithm and
5432 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5433 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5434 compatible with 'int').
5436 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5437 ** version, try to negotiate the highest version support by the GnuTLS server,
5438 ** instead of the lowest.
5439 Reported by <Pasi.Eronen@nokia.com>.
5441 ** Replace old constructs with use of gnulib modules.
5442 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5443 the code. If the headers doesn't exist on the target system, gnulib
5444 will make sure its replacement header files are used instead.
5446 ** Fix SOVERSION computation for *.def files.
5447 This fixes build errors similar to "No rule to make target
5448 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5450 ** gnutls_check-version uses strverscmp from gnulib.
5452 ** Update of gnulib files.
5454 ** API and ABI modifications:
5455 gnutls_transport_set_errno: ADD
5456 gnutls_transport_set_global_errno: ADD
5458 * Version 1.5.3 (released 2006-10-26)
5460 ** Add new self-test of RSA-MD5 signature chains.
5461 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5462 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5463 and is based on the work by Marc Stevens et al, see
5464 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5466 ** Re-factor self tests.
5468 ** The include copy of Libtasn1 is updated to version 0.3.7.
5470 ** The included copy of OpenCDK is updated to version 0.5.11.
5472 ** Fix the filename of the *.def file on Windows after library version bump.
5474 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5475 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5476 gnulib modules. Earlier we could only use the LGPL'ed module from
5477 gnulib, because two gnulib directories in the same project didn't
5480 ** API and ABI modifications:
5481 No changes since last version.
5483 * Version 1.5.2 (released 2006-10-03)
5485 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5486 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5487 shared library version than this version, so you'll have to remove
5488 them and possibly relink your applications. The reason for this is
5489 that no API/ABI changes have been made since the 1.4.x branch, and
5490 that incrementing the shared library version was a mistake. Reported
5491 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5493 ** Fix off-by-one error when computing length to malloc.
5494 The code is used by gnutls_openpgp_add_keyring_file and
5495 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5496 <agl@imperialviolet.org>.
5498 ** Add version script for the GnuTLS C++ library.
5499 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5501 ** Fix the C++ compiler detection logic.
5502 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5504 ** Update of gnulib files.
5506 ** API and ABI modifications:
5507 No changes since last version.
5509 * Version 1.5.1 (released 2006-09-21)
5511 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5512 ** Crypto 06 rump session attack.
5513 In particular, we check that the digestAlgorithm.parameters field is
5514 missing or empty, to avoid that it can contain "garbage" that may be
5515 used to alter the numeric properties of the signature. See
5516 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5517 not exactly the same as the problem we fix here). Reported by Yutaka
5518 OIWA <y.oiwa@aist.go.jp>.
5520 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5521 up to date information.
5523 ** Add self test to test for above flaw.
5525 ** Fix gnutls-cli-debug regarding resume support detection.
5526 Earlier, if the session-id from the server had a length of 0, it would
5527 indicate that the server supports resumption, which isn't the case.
5528 Reported by Kataja Kai <kai.kataja@op.fi>.
5530 ** Fix building of examples on FreeBSD by including netinet/in.h.
5531 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5533 ** Fix certtool bug that caused the private key to not be loaded when
5534 generating a certificate with --load-request, which in turn triggered
5535 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5536 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5538 ** gnutls-cli and gnutls-serv works on Windows.
5539 The problem was the select() call that doesn't work on file
5540 descriptors (stdin) on Windows. We borrowed some code from plibc to
5541 solve this. It appears to be somewhat unreliable though.
5543 ** Autoconf 2.60 is now used.
5545 ** API and ABI modifications:
5546 No changes since last version.
5548 * Version 1.5.0 (released 2006-08-13)
5550 ** Change SRP and Cert-Type extensions to match IANA registry.
5552 ** Fixed bug in OpenPGP authentication handshake.
5554 ** Improvements for building under MinGW.
5555 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5556 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5557 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5558 at run-time from ws2_32.dll, and falls back on a simple replacement if
5559 it is not available. Builds the library with -mms-bitfields
5560 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5561 create *.def files, which are installed.
5563 ** The examples now (conditionally) include config.h and link to gnulib.
5564 No other source changes were necessary, so the examples should
5565 continue to be possible to use stand-alone without any autoconf or
5568 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5569 You may unconditionally disable it with --disable-cxx. See
5570 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5573 ** Made command line tool '--version' behave according to GNU Standards.
5574 This enables 'make distcheck' to succeed.
5576 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5578 ** Make --without-included-libtasn1 work.
5579 Reported by Daniel Black <dragonheart@gentoo.org>.
5581 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5582 See http://www.gnu.org/software/gnutls/security.html regardging
5583 GNUTLS-SA-2006-2 for more up to date information. Reported by
5584 satyakumar <satyam_kkd@hyd.hellosoft.com>.
5586 ** API and ABI modifications:
5587 No changes since last version.
5589 * Version 1.4.5 (released 2006-11-06)
5591 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5592 ** version, try to negotiate the highest version support by the GnuTLS server,
5593 ** instead of the lowest.
5594 Reported by <Pasi.Eronen@nokia.com>.
5596 ** Fix typo in doc/examples/ex-serv-pgp.c.
5597 Reported by Adam Langley" <agl@imperialviolet.org>.
5599 ** API and ABI modifications:
5600 No changes since last version.
5602 * Version 1.4.4 (released 2006-09-12)
5604 ** Relax the test that caught signatures that exploit the variant of
5605 ** Bleichenbacher's Crypto 06 rump session attack on our
5606 ** verification logic flaw.
5607 In particular, we now permit the digestAlgorithm.parameters field to
5608 be present but empty, whereas in 1.4.3 we actually checked that the
5611 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5612 The messages are only printed in debug mode, which is not recommended
5613 for normal use, and thus logging this situation cannot be abused as an
5614 oracle in typical recommended situations.
5616 ** API and ABI modifications:
5617 No changes since last version.
5619 * Version 1.4.3 (released 2006-09-08)
5621 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5622 ** Crypto 06 rump session attack.
5623 In particular, we check that the digestAlgorithm.parameters field is
5624 empty, to avoid that it can contain "garbage" that may be used to
5625 alter the numeric properties of the signature. See
5626 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

5640 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
5642 ** API and ABI modifications:
5643 No changes since last version.
5645 * Version 1.4.2 (released 2006-08-12)
5647 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5648 This can happen if you call gnutls_certificate_verify_peers2 and have
5649 a certain mix of local CA certificates and the peer send special
5650 certificates, that together trigger certain behaviour. It is not
5651 known at this point whether the crash can be triggered without the
5652 special local CA certificate, and thus turn this into a remote crash
5653 of clients that verify server certificates when they talk to a server
5654 with the special server certificate. See GNUTLS-SA-2006-2 on
5655 http://www.gnu.org/software/gnutls/security.html for more up to date
5656 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5658 ** Change SRP and Cert-Type extensions to match IANA registry.
5660 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5662 ** Make --without-included-libtasn1 work.
5663 Reported by Daniel Black <dragonheart@gentoo.org>.
5665 ** API and ABI modifications:
5666 No changes since last version.
5668 * Version 1.4.1 (released 2006-06-14)
5670 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5672 ** Fixed bug in OpenPGP authentication handshake.
5674 ** Fixed typographical in man pages.
5676 ** Build fixes of the manual.
5678 ** Added Swedish translation.
5680 ** API and ABI modifications:
5681 No changes since last version.
5683 * Version 1.4.0 (released 2006-05-15)
5685 ** Remove GnuTLS 0.8.x compatibility functions.
5687 ** The libgcrypt RNG is initialized in gnutls_global_init().
5689 ** TLS/IA API changes from Emile van Bergen.
5690 A dummy credential structure is not needed now, if you wish to use the
5691 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5694 ** The self-tests are now run under valgrind, if it is installed.
5696 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5698 ** The command line tools now use getaddrinfo and support IPv6.
5700 ** API and ABI modifications:
5701 _gnutls_x509_get_raw_crt_activation_time,
5702 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5703 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5704 gnutls_ia_enable: Added.
5706 * Version 1.3.5 (released 2006-03-08)
5708 ** Error messages are now translated using GNU Gettext.
5710 ** The function gnutls_x509_crt_to_xml now return an internal error.
5711 This means that the code to convert X.509 certificates to XML format
5712 does not work any more. The reason is that the function called
5713 libtasn1 internal functions. It seems unclean for libtasn1 to export
5714 the APIs needed here. Instead it would be better to implement XML
5715 support inside libtasn1 properly. If you need this functionality
5716 strongly, please consider looking into implementing this suggested
5717 approach instead. As a workaround, you may also modify lib/x509/xml.c
5718 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5720 ** Libraries are now built with libtool's -no-undefined.
5721 This helps producing libraries for Windows using mingw32.
5723 ** Doc fixes to explain that gnutls_record_send can block.
5725 ** Libtasn1 0.3.1 or later is now required.
5726 The include copy has been updated too.
5728 ** gnutls-cli can now recognize services and port numbers with the -p option.
5730 ** API and ABI modifications:
5731 No changes since last version.
5733 * Version 1.3.4 (released 2006-02-09)
5735 ** Fix read of out bounds bug in DER parser.
5736 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5737 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5738 previous bug fix. The included libtasn1 version in GnuTLS has been
5741 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5742 longer invalidate a session if the underlying send fails, but it will
5743 prevent future writes. That is to allow reading the already received data.
5744 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5746 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5747 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5748 more than one certificates were added. Report and patch by Max Kellermann.
5750 ** Fix build problems of OpenCDK on AIX.
5751 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5753 ** API and ABI modifications:
5754 No changes since last version.
5756 * Version 1.3.3 (released 2006-01-12)
5758 ** New API to access the TLS master secret.
5759 When possible, you should use the TLS PRF functions instead.
5760 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5762 ** Improved handling when multiple libraries use GnuTLS at the same time.
5763 Now gnutls_global_init() can be called multiple times, and
5764 gnutls_global_deinit() will only deallocate the structure when it has
5765 been called as many times as gnutls_global_init() was called.
5767 ** Added a self test of TLS resume functionality.
5769 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5771 ** Documentation fixes about thread unsafety, prompted by
5772 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5773 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5774 thread safe. Careful callers may want to protect the call using a
5775 mutex. The problem could also be ignored, which would cause a memory
5776 leak under rare conditions when two threads invoke the function
5777 roughly at the same time.
5779 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5781 ** The code was indented again, including the external header files.
5783 ** API and ABI modifications:
5784 New functions to retrieve the master secret value:
5785 gnutls_session_get_master_secret
5787 Add a 'const' keyword to existing API:
5788 gnutls_x509_crq_get_challenge_password
5790 * Version 1.3.2 (released 2005-12-15)
5792 ** GnuTLS now support TLS Inner application (TLS/IA).
5793 This is per draft-funk-tls-inner-application-extension-01. This
5794 functionality is added to libgnutls-extra, so it is licensed under the
5795 GNU General Public License.
5797 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5798 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5799 and EAP-TTLS. One function to access the raw PRF and one to access
5800 the PRF seeded with the client/server random fields are provided.
5801 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5803 ** New APIs to acceess the client and server random fields in a session.
5804 These fields can be useful by protocols using TLS. Note that these
5805 fields are typically used as input to the TLS PRF, and if this is your
5806 intended use, you should use the TLS PRF API that use the
5807 client/server random field directly. Suggested by Jouni Malinen
5808 <jkmaline@cc.hut.fi>.
5810 ** Internal type cleanups.
5811 The uint8, uint16, uint32 types have been replaced by uint8_t,
5812 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5813 correct types on platforms that lack them. The uint type have been
5814 replaced by unsigned.
5816 ** API and ABI modifications:
5817 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5821 New functions to retrieve the session's client and server random values:
5822 gnutls_session_get_server_random
5823 gnutls_session_get_client_random
5825 New function, to perform TLS/IA handshake:
5828 New function to decide whether to do a TLS/IA handshake:
5829 gnutls_ia_handshake_p
5831 New functions to allocate a TLS/IA credential:
5832 gnutls_ia_allocate_client_credentials
5833 gnutls_ia_free_client_credentials
5834 gnutls_ia_allocate_server_credentials
5835 gnutls_ia_free_server_credentials
5837 New functions to handle the AVP callback:
5838 gnutls_ia_set_client_avp_function
5839 gnutls_ia_set_client_avp_ptr
5840 gnutls_ia_get_client_avp_ptr
5841 gnutls_ia_set_server_avp_function
5842 gnutls_ia_set_server_avp_ptr
5843 gnutls_ia_get_server_avp_ptr
5845 New functions, to toggle TLS/IA application phases:
5846 gnutls_ia_require_inner_phase
5848 New function to mix session keys with inner secret:
5849 gnutls_ia_permute_inner_secret
5851 Low-level API (used internally by gnutls_ia_handshake):
5852 gnutls_ia_endphase_send
5856 New functions that can be used after successful TLS/IA negotiation:
5857 gnutls_ia_generate_challenge
5858 gnutls_ia_extract_inner_secret
5860 Enum type with TLS/IA modes:
5863 Enum type with TLS/IA packet types:
5866 Enum values for TLS/IA alerts:
5867 GNUTLS_A_INNER_APPLICATION_FAILURE
5868 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5870 New error codes, to signal when an application phase has finished:
5871 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5872 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5874 New error code to signal TLS/IA verify failure:
5875 GNUTLS_E_IA_VERIFY_FAILED
5877 * Version 1.3.1 (released 2005-12-08)
5879 ** Support for DHE-PSK cipher suites has been added.
5880 This method offers perfect forward secrecy.
5882 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5883 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5885 ** Corrected a bug in certtool for 64 bit machines. Reported
5886 by Max Kellermann <max@duempel.org>.
5888 ** New function to set a X.509 private key and certificate pairs, and/or
5889 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5890 <emile@e-advies.nl>.
5892 The integrity of the PKCS#12 file is protected through a password
5893 based MAC; public-key based signatures for integrity protection are
5894 not supported. PKCS#12 bags may be encrypted using password derived
5895 symmetric keys, public-key based encryption is not supported. The
5896 PKCS#8 keys may be encrypted using passwords. The API use the same
5897 password for all operations. We believe that any more flexibility
5898 create too much complexity that would hurt overall security, but may
5899 add more PKCS#12 related APIs if real-world experience indicate
5902 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5903 reported by Emile van Bergen <emile@e-advies.nl>.
5904 This will enable "certtool -k -8" to parse those keys.
5906 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5907 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5908 certtool would have encrypted the key using an empty password.
5910 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5911 Earlier it would have prompted the user for it, even if --password was
5914 ** Added self test of PKCS#8 parsing.
5915 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5916 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5919 ** API and ABI modifications:
5920 New function to set X.509 credentials from a PKCS#12 file:
5921 gnutls_certificate_set_x509_simple_pkcs12_file
5923 New gnutls_kx_algorithm_t enum type:
5926 New API to return session data (basically same as gnutls_session_get_data):
5927 gnutls_session_get_data2
5929 New API to set PSK Diffie-Hellman parameters:
5930 gnutls_psk_set_server_dh_params
5932 * Version 1.3.0 (2005-11-15)
5934 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5935 This add several new APIs, see below. Read the updated manual for
5936 more information. A new self test "pskself" has been added, that will
5937 test this functionality.
5939 ** The session resumption data are now system independent.
5941 ** The code has been re-indented to conform to the GNU coding style.
5943 ** Removed the RIPEMD ciphersuites.
5945 ** Added a discussion of the internals of gnutls in manual.
5947 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5949 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5951 ** Make sure config.h is included first in a few files, from Albert Chin.
5953 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
5955 ** Don't install SRP programs and man pages if --disable-srp-authentication,
5958 ** API and ABI modifications:
5959 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
5961 New gnutls_credentials_type_t credential type:
5964 New credential types:
5965 gnutls_psk_server_credentials_t
5966 gnutls_psk_client_credentials_t
5968 New functions to allocate PSK credentials:

5970 gnutls_psk_free_client_credentials
5971 gnutls_psk_free_server_credentials
5972 gnutls_psk_allocate_server_credentials
5974 New enum type for PSK key flags:
5975 gnutls_psk_key_flags
5977 New function prototypes for credential callback:
5978 gnutls_psk_client_credentials_function
5979 gnutls_psk_server_credentials_function
5981 New function to set PSK username and key:
5982 gnutls_psk_set_client_credentials
5984 New function to set PSK passwd file:
5985 gnutls_psk_set_server_credentials_file
5987 New function to extract PSK user in server:
5988 gnutls_psk_server_get_username
5990 New functions to set PSK callback:
5991 gnutls_psk_set_server_credentials_function
5992 gnutls_psk_set_client_credentials_function
5994 Use size_t instead of int for output size parameter:
5995 gnutls_srp_base64_encode
5996 gnutls_srp_base64_decode
5998 * Version 1.2.11 (2006-05-11)
5999 - The function gnutls_x509_crt_to_xml is not supported any more, and
6000 return an internal error. The reason is that the function called
6001 internal libtasn1 functions which are no longer exported from
6003 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
6004 - Updated gnulib compatibility files.
6005 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
6006 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
6007 - API and ABI modifications:
6008 No changes since last version.
6010 * Version 1.2.10 (2006-02-09)
6011 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
6012 <admin@gleg.net>, and debugging help from Protover SSL.
6013 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
6014 The included version has been updated too.
6015 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
6016 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
6017 - Corrected a bug in certtool for 64 bit machines. Reported
6018 by Max Kellermann <max@duempel.org>.
6019 - Corrected bugs in gnutls_certificate_set_x509_crl() and
6020 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6021 more than one certificates were added. Report and patch by Max Kellermann.
6022 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6023 longer invalidate a session if the underlying send fails, but it will
6024 prevent future writes. That is to allow reading the already received data.
6025 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6027 * Version 1.2.9 (2005-11-07)
6028 - Documentation was updated and improved.
6029 - RSA-MD2 is now supported for verifying digital signatures.
6030 - Due to cryptographic advances, verifying untrusted X.509
6031 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
6032 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
6033 applications that must remain interoperable, you can use the
6034 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
6035 flags when verifying certificates. Naturally, this is not
6036 recommended default behaviour for applications. To enable the
6037 broken algorithms, call gnutls_certificate_set_verify_flags with the
6038 proper flag, to change the verification mode used by
6039 gnutls_certificate_verify_peers2.
6040 - Make it possible to send empty data through gnutls_record_send,
6041 to align with the send(2) API.
6042 - Some changes in the certificate receiving part of handshake to prevent
6043 some possible errors with non-blocking servers.
6044 - Added numeric version symbols to permit simple CPP-based feature
6045 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
6046 - The (experimental) low-level crypto alternative to libgcrypt used
6047 earlier (Nettle) has been replaced with crypto code from gnulib.
6048 This leads to easier re-use of these components in other projects,
6049 leading to more review and simpler maintenance. The new configure
6050 parameter --with-builtin-crypto replace the old --with-nettle, and
6051 must be used if you wish to enable this functionality. See README
6052 under "Experimental" for more information. Internally, GnuTLS has
6053 been updated to use the new "Generic Crypto" API in gl/gc.h. The
6054 API is similar to the old crypto/gc.h, because the gnulib code were
6055 based on GnuTLS's gc.h.
6056 - Fix compiler warning in the "anonself" self test.
6057 - API and ABI modifications:
6058 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
6059 This doesn't reflect a change in behaviour,
6060 so we don't break backwards compatibility.
6061 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
6062 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
6063 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
6064 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
6066 gnutls_x509_crt_list_verify,
6067 gnutls_x509_crt_verify, or
6068 gnutls_certificate_set_verify_flags.
6069 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
6070 used when broken signature algorithms
6071 is used (currently RSA-MD2/MD5).
6072 LIBGNUTLS_VERSION_MAJOR,
6073 LIBGNUTLS_VERSION_MINOR,
6074 LIBGNUTLS_VERSION_PATCH,
6075 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
6076 version number, can be used for feature existence
6079 * Version 1.2.8 (2005-10-07)
6080 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
6081 - Don't install the auxilliary libexamples library used by the
6082 examples in doc/examples/ on "make install", report and tiny patch
6083 from Thomas Klausner <tk@giga.or.at>.
6084 - If you pass a X.509 CA or PGP trust database to the command line
6085 tool, it will now abort the connection if the server certificate
6086 validation fails. Use the parameter --insecure to continue even
6087 after certificate validation failures. Inspired from discussion
6088 with Alexander Kotelnikov <sacha@myxomop.com>.
6089 - The test for socklen_t has been moved to gnulib.
6090 - Link failures for duplicate or missing "program_name" symbol has been fixed,
6091 patch from Martin Lambers <marlam@marlam.de>.
6092 - The command line tool and the examples no longer uses mmap or bzero,
6093 to make them more portable, patch from Martin Lambers
6095 - Made the PKCS #12 API handle null passwords. Based on patch by
6096 Anton Altaparmakov <aia21@cam.ac.uk>.
6097 - The GTK-DOC manual should build with current released tools.
6098 (But a copy of the output is included, so the tools are not required.)
6099 - The inet_ntop function is now used through gnulib.
6100 - API and ABI modifications:
6101 No changes since last version.
6103 * Version 1.2.7 (2005-09-09)
6104 - The GnuTLS and GnuTLS-extra libraries are now built with versioned symbols.
6105 - Certtool now complains when reading out-of-range X.509 serial
6106 numbers, suggested by Fran <e_agf@yahoo.es>.
6107 - Certtool now uses the readline library (when available) when reading
6108 X.509 serial numbers.
6109 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
6110 - Fixed compile warning regarding socklen_t on Mingw32, reported by
6111 Martin Lambers <marlam@marlam.de>.
6112 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
6113 - Gnulib is now used for the core library, enabling future code cleanups.
6114 - The gnutls-cli tool now use gnutls_certificate_verify_peers2,
6115 suggested by Daniel Stenberg <daniel@haxx.se>.
6116 - Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.
6117 - Minilibtasn1 is now 0.2.17 (removed optional use of C99 macros).
6118 - Disable zlib support if zlib.h is not present.
6119 - A number of internal cleanups.
6120 - API and ABI modifications:
6121 No changes since last version.
6123 * Version 1.2.6 (2005-07-16)
6124 - MiniLZO updated to version 2.01 and moved to separate directory.
6125 - Collision between system LZO header files and MiniLZO header file
6126 fixed, reported by Matthias Urlichs <smurf@smurf.noris.de>.
6127 - Will now test for liblzo functionality in liblzo2 too, reported by
6128 Thomas Klausner <tk@giga.or.at>.
6129 - Minilibtasn1 is now 0.2.14 (no code changes).
6130 - Some code changes to avoid GTK-DOC warnings.
6131 - API and ABI modifications:
6132 No changes since last version.
6134 * Version 1.2.5 (2005-07-03)
6135 - More builddir != srcdir fixes, reported by Mike Castle
6136 <dalgoda@ix.netcom.com>.
6137 - Fixed off-by-one bug in the size parameter of gnutls_x509_crt_get*_dn,
6138 reported by Adam Langley <alangley@gmail.com>.
6139 - Corrected some stuff in minilzo detection. Pointed out by
6141 - MiniLZO updated to version 2.00.
6142 - gnutls_x509_crt_list_import now accept a DER formatted CRL.
6143 - API and ABI modifications:
6144 No changes since last version.

6177 function prototypes during compile time.
6178 - API and ABI modifications:
6179 No changes since last version. At least not intentional, but due
6180 to the include header changes, there may be inadvertant changes,
6181 please let us know if you find any.
