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

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

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

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

413 ** libgnutls: SUITEB128 and SUITEB192 priority strings account
414 for the RFC6460 requirements.
416 ** libgnutls: Added new security parameter GNUTLS_SEC_PARAM_LEGACY
417 to account for security level of 96-bits.
419 ** libgnutls: In client side if server does not advertise any
420 known CAs and only a single certificate is set in the credentials,
423 ** libgnutls: Added functions to parse authority key identifiers
424 when stored as a 'general name' and serial combo.
426 ** libgnutls: Added function to force explicit reinitialization
427 of PKCS #11 modules. This is required on the child process after
428 a fork (if PKCS #11 functionality is desirable).

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

540 ** gnutls-cli/serv: Set don't fragment bit in DTLS sessions
541 in Linux as well as in BSD.
543 ** gnutls-cli: Fixed reading from windows terminals.
545 ** libgnutls: When GNUTLS_OPENPGP_FMT_BASE64 is specified
546 the stream is assumed to be base64 encoded (previously
547 the encoding was auto-detected). This avoids a decoding
548 issue in windows systems.
550 ** libgnutls: Corrected ciphersuite GNUTLS_ECDHE_PSK_AES_256_CBC_SHA384
552 ** libgnutls: Added ciphersuites: GNUTLS_PSK_WITH_AES_256_GCM_SHA384

570 it will only list the ciphersuites that are enabled by the given
573 ** libgnutls: Added new priority string %SERVER_PRECEDENCE, which
574 changes the ciphersuite selection procedure. If specified the server
575 priorities will be used for selection instead of the client's.
577 ** libgnutls: Optimizations in Diffie-Hellman parameters generation
580 ** libgnutls: When session tickets are negotiated and used in a
581 session, a server will not store that session data into its cache.
583 ** libgnutls: Added the SECP192R1 curve.
585 ** libgnutls: Added gnutls_priority_get_cipher_suite_index() to
586 allow listing the ciphersuites enabled in a priority structure.

1179 subkey instead of setting explicitly one.
1181 ** libgnutls: Corrected default behavior in record version of Client Hellos.
1183 ** libgnutls-openssl: modified to use modern gnutls' functions.
1184 This introduces an ABI incompatibility with previous versions.
1186 ** API and ABI modifications:
1187 gnutls_pubkey_import_openpgp: MODIFIED
1192 ** libgnutls: The deprecated gnutls_x509_privkey_sign_hash() was
1193 replaced by gnutls_privkey_sign_hash2().
1195 ** libgnutls: gnutls_pubkey_verify_data, gnutls_pubkey_verify_hash,
1196 gnutls_x509_privkey_verify_data, gnutls_x509_crt_verify_data,
1197 gnutls_x509_crt_verify_hash return the negative error code
1198 GNUTLS_E_PK_SIG_VERIFY_FAILED if verification fails to simplify error
1201 ** libgnutls: Added helper functions for signature verification:
1202 gnutls_pubkey_verify_data() and gnutls_pubkey_import_privkey().
1204 ** libgnutls: Modified gnutls_privkey_sign_data().
1206 ** gnutls_x509_crl_privkey_sign2(), gnutls_x509_crq_sign2()
1207 gnutls_x509_privkey_sign_hash(), gnutls_x509_privkey_sign_data(),
1208 gnutls_x509_crt_verify_hash(), gnutls_x509_crt_verify_data(), were
1209 deprecated for gnutls_x509_crl_privkey_sign(),
1210 gnutls_x509_crq_privkey_sign(), gnutls_privkey_sign_hash(),
1211 gnutls_privkey_sign_data(), gnutls_pubkey_verify_hash()
1212 gnutls_pubkey_verify_data() respectively.
1214 ** libgnutls: gnutls_*_export_raw() functions now add leading zero in
1217 ** libgnutls: Added convenience functions gnutls_x509_crl_list_import2()
1218 and gnutls_x509_crt_list_import2().
1220 ** crypto.h: Fix use with C++.
1221 Reported by "Brendan Doherty" <brendand@gentrack.com>.

1250 * Version 2.11.6 (released 2010-12-06)
1252 ** libgnutls: Record version of Client Hellos is now set by default to
1253 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
1256 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
1257 This makes us comply with RFC3279. Reported by Michael Rommel.
1259 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
1261 ** API and ABI modifications:
1262 No changes since last version.
1264 * Version 2.11.5 (released 2010-12-01)
1266 ** libgnutls: Reverted default behavior for verification and
1267 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
1268 V1 trusted CAs are allowed, unless the new flag is specified.
1270 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
1271 Reported by Jeffrey Walton.
1273 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
1274 as priority strings. Those allow to set all the supported algorithms
1277 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
1279 ** gnutls-cli: Print channel binding only in verbose mode.
1280 Before it printed it after the 'Compression:' output, thus breaking
1281 Emacs starttls.el string searches.
1283 ** API and ABI modifications:
1284 gnutls_pkcs11_token_init: New function
1285 gnutls_pkcs11_token_set_pin: New function
1287 * Version 2.11.4 (released 2010-10-15)
1289 ** libgnutls: Add new API gnutls_session_channel_binding.
1290 The function is used to get the channel binding data. Currently only
1291 the "tls-unique" (RFC 5929) channel binding type is supported, through
1292 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
1295 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
1297 ** doc: Added pkcs11.h header file to GTK-DOC manual.
1299 ** build: Update gnulib files.
1301 ** i18n: Update translations.
1303 ** tests: Add self tests gendh.c. Speed up Guile self checks.
1305 ** API and ABI modifications:
1306 gnutls_session_channel_binding: New function.
1307 gnutls_channel_binding_t: New enumeration.
1308 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
1309 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
1311 * Version 2.11.3 (released 2010-10-14)
1313 ** Indent code to follow the GNU Coding Standard.
1314 You should be able to unpack the 2.11.2 release and run 'make indent'
1315 twice to get exactly the same content as 2.11.3 except for generated
1316 files. Using GNU Indent 2.2.11.
1318 ** API and ABI modifications:
1319 No changes since last version.
1321 * Version 2.11.2 (released 2010-10-08)
1323 ** libgnutls: Several bug fixes on session resumption
1324 and session tickets support.
1326 ** libgnutls: Add new extended key usage ipsecIKE.
1328 ** certtool: Renamed PKCS #11 options to: --p11-provider,
1329 --p11-export-url, --p11-list-certs, --p11-list-certs,
1330 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
1331 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
1332 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1335 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1336 introduced with the new nettle code.
1338 ** libgnutls: Corrected advertizing issue for session tickets.
1340 ** API and ABI modifications:
1341 gnutls_x509_crt_get_subject_unique_id: ADDED.
1342 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1344 * Version 2.11.1 (released 2010-09-14)
1346 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1347 to use the libgcrypt back end.
1349 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1350 backend crypto library.
1352 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1354 ** libgnutls: Several updates in the buffering internal interface.
1356 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1357 tabs are being skipped.
1359 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1361 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1364 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1365 system calls. Applications that depended on it being 1 should explicitly call
1366 gnutls_transport_set_lowat().
1368 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1369 to ECRYPT II recommendations. Mappings were moved to a single location
1370 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1371 and 3072 keys only).
1373 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1374 gnutls_x509_privkey_import_pkcs8() without a password, if it
1375 is unable to decode the key.
1377 ** libgnutls: HMAC-MD5 no longer used by default.
1379 ** API and ABI modifications:
1380 gnutls_openpgp_privkey_sec_param: ADDED
1381 gnutls_x509_privkey_sec_param: ADDED
1383 * Version 2.11.0 (released 2010-07-22)
1385 ** libgnutls: support scattered write using writev(). This takes
1386 advantage of the new buffering layer and allows queuing of packets
1387 and flushing them. This is currently used for handshake messages
1390 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1391 alternative locking procedures. By default the system available
1392 locking is used. In *NIX pthreads are used and in windows the
1393 critical section API. This follows a different approach than the
1394 previous versions that depended on libgcrypt initialization. The
1395 locks are now set by default in systems that support it. Programs
1396 that used gcry_control() to set thread locks should insert it into
1398 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1402 ** libgnutls: Added support for reading DN from EV-certificates.
1404 jurisdictionOfIncorporationLocalityName,
1405 jurisdictionOfIncorporationStateOrProvinceName,
1406 jurisdictionOfIncorporationCountryName
1408 ** libgnutls: Added support for DSA signing/verifying with bit
1411 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1412 has to be called to register any required md5 handlers.
1414 ** libgnutls: Internal buffering code was replaced by simpler
1415 code contributed by Jonathan Bastien-Filiatrault.
1417 ** libgnutls: Internal API for extensions augmented to allow
1418 safe storing and loading of data on resumption. This allows writing
1419 self-contained extensions (when possible). As a side effect
1420 the OPRFI extension was removed.
1422 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1424 ** libgnutls: Added PKCS #11 support and an API to access objects in
1425 gnutls/pkcs11.h. Currently certificates and public keys can be
1426 imported from tokens, and operations can be performed on private keys.
1428 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1430 ** libgnutls: Added initial support for the nettle library. It uses
1431 the system's random generator for seeding. That is /dev/urandom in Linux,
1432 system calls in Win32 and EGD on other systems.
1434 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1435 works even when resuming a session.
1437 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1438 similar gnutls_certificate_set_server_retrieve_function() and
1439 gnutls_certificate_set_client_retrieve_function(). In addition it support
1440 PKCS #11 private keys.
1442 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1443 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1445 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1446 sizes for private keys using a human understandable scale.
1448 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1449 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1450 --pkcs11-delete-url, --pkcs11-write
1452 certtool: The --pkcs-cipher is taken into account when generating a
1453 private key. The default cipher used now is aes-128. The old behavior can
1454 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1456 certtool: Added --certificate-pubkey to print the public key of the
1459 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1460 can now accept a PKCS #11 URL in addition to a file. This will allow for
1461 example to use the Gnome-keyring trusted certificate list to verify
1462 connections using a url such as:
1463 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1544 * Version 2.10.1 (released 2010-07-25)
1546 ** libgnutls: Added support for broken certificates that indicate RSA
1549 ** gnutls-cli: Allow verification using V1 CAs.
1551 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1552 gnutls_x509_privkey_import_pkcs8() without a password, if it
1553 is unable to decode the key.
1555 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1556 a memory leak. Reported by Mads Kiilerich.
1558 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1559 issue a warning, that the output key might not be working everywhere.
1561 ** certtool: The --pkcs-cipher is taken into account when generating a
1562 private key. The default cipher used now is aes-128. The old behavior
1563 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1565 ** API and ABI modifications:
1566 No changes since last version.
1568 * Version 2.10.0 (released 2010-06-25)
1570 ** API and ABI modifications:
1571 No changes since last version.
1573 * Version 2.9.12 (released 2010-06-17)
1575 ** gnutls-cli: Make --starttls work again.
1576 Problem introduced in patch to use read() instead of fgets() committed
1579 ** API and ABI modifications:
1580 No changes since last version.
1582 * Version 2.9.11 (released 2010-06-07)
1584 ** libgnutls: Removed two APIs related to safe renegotiation.
1585 Use priority strings instead. The APIs were
1586 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1587 (Remember that we don't promise ABI stability during development
1588 series, so this doesn't cause an shared library ABI increment.)
1590 ** tests: More self testing of safe renegotiation extension.
1591 See tests/safe-renegotiation/README for more information.
1593 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1595 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1597 ** API and ABI modifications:
1598 gnutls_safe_negotiation_set_initial: REMOVED.
1599 gnutls_safe_renegotiation_set: REMOVED.
1601 * Version 2.9.10 (released 2010-04-22)
1603 ** libgnutls: Time verification extended to trusted certificate list.
1604 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1607 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1608 Based on patch by Pavan Konjarla. Adds new constant
1609 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1611 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1612 Solves the issue discussed in:
1613 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1614 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1615 Note that to allow connecting to unpatched servers the full protection
1616 is only enabled if the priority string %SAFE_RENEGOTIATION is
1617 specified. You can check whether protection is in place by querying
1618 gnutls_safe_renegotiation_status(). New error codes
1619 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1620 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1622 ** libgnutls: When checking openpgp self signature also check the signatures
1624 Ilari Liusvaara noticed and reported the issue and provided test
1627 ** libgnutls: Added cryptodev support (/dev/crypto).
1628 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1629 benchmark utility for AES. Adds new error codes
1630 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1632 ** libgnutls: Exported API to access encryption and hash algorithms.
1633 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1634 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1635 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1636 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1637 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1638 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1639 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1641 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1642 verification of certificate upon receipt rather than waiting until the
1643 end of the handshake.
1645 ** libgnutls: Don't send alerts during handshake.
1646 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1648 ** certtool: Corrected two issues that affected certificate request generation.
1649 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1650 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1651 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1652 those parameters there since other implementations don't do either and having
1653 them does not seem to offer anything (anyway you need the signer's certificate
1654 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1655 This however has the side-effect that public key IDs shown by certtool are
1656 now different than previous gnutls releases.
1657 (3) the option --pgp-certificate-info will verify self signatures
1659 ** certtool: Allow exporting of Certificate requests on DER format.
1661 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1663 ** gnutls-cli: Handle reading binary data from server.

1731 Reported by Tang Tong.
1733 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1734 ** extension and certificate verify field.
1735 This requires changes for TLS 1.2 servers and clients that use
1736 callbacks for certificate retrieval. They are now required to check
1737 with gnutls_sign_algorithm_get_requested() whether the certificate
1738 they send complies with the peer's preferences in signature

1824 Reported by Howard Chu <hyc@symas.com> in
1825 <https://savannah.gnu.org/support/?106975>.
1827 ** Fix use of deprecated types internally.
1828 Use of deprecated types in GnuTLS from now on will lead to a compile
1829 error, to prevent this from happening again.

1832 No changes since last version.
1834 * Version 2.9.3 (released 2009-08-19)
1836 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.

1838 gnutls_session_ticket_enable_server, and
1839 gnutls_session_ticket_key_generate.

1848 * Version 2.9.2 (released 2009-08-14)
1850 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1851 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1852 into 1) not printing the entire CN/SAN field value when printing a
1853 certificate and 2) cause incorrect positive matches when matching a
1854 hostname against a certificate. Some CAs apparently have poor
1855 checking of CN/SAN values and issue these (arguable invalid)
1856 certificates. Combined, this can be used by attackers to become a
1857 MITM on server-authenticated TLS sessions. The problem is mitigated
1858 since attackers needs to get one certificate per site they want to
1859 attack, and the attacker reveals his tracks by applying for a
1860 certificate at the CA. It does not apply to client authenticated TLS
1861 sessions. Research presented independently by Dan Kaminsky and Moxie
1862 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1863 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1865 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1866 The function may fail incorrectly when an earlier certificate was
1867 imported to the same gnutls_x509_crt_t structure.
1869 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1871 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1872 Before it always returned false. Reported by Peter Hendrickson
1873 <pdh@wiredyne.com> in

1883 The encryption key derived from the password was incorrect for (on
1884 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1885 Tomas" <tomas.kukosa@siemens-enterprise.com> in

1889 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1890 gnutls_dh_get_peers_public_bits. Before the reported value was
1891 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
1892 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.

1900 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1901 Before we required that the runtime library used the same (or more
1902 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1903 that the runtime usage is above the minimum required. Reported by
1904 Marco d'Itri <md@linux.it> via Andreas Metzler

1943 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1944 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1946 Note: As a side effect of this change, the "public key identifier"
1947 value computed for a certificate using this version of GnuTLS will be
1948 different from values computed using earlier versions of GnuTLS.
1950 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1951 ** optional SignatureAlgorithm parameter field.
1952 VeriSign rejected these CSRs. They are stricly speaking not needed
1953 since you need the signer's certificate to verify the certificate
1954 signature anyway. Reported by Wilankar Trupti

2214 No offically supported interfaces have been modified or removed. The
2215 library should be completely backwards compatible on both the source
2218 The shared library no longer exports some symbols that have never been
2219 officially supported, i.e., not mentioned in any of the header files.
2225 Normally when symbols are removed, the shared library version has to
2226 be incremented. This leads to a significant cost for everyone using
2227 the library. Because none of the above symbols have ever been
2228 intended for use by well-behaved applications, we decided that the it
2229 would be better for those applications to pay the price rather than
2230 incurring problems on the majority of applications.
2232 If it turns out that applications have been using unofficial
2233 interfaces, we will need to release a follow-on release on the v2.8
2234 branch to exports additional interfaces. However, initial testing
2235 suggests that few if any applications have been using any of the
2238 Although not a new change compared to 2.6.x, we'd like to remind you
2239 interfaces have been modified so that X.509 chain verification now
2240 also checks activation/expiration times on certificates. The affected

2250 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2251 we gave our rationale for it in earlier release notes.
2253 The following symbols have been added to the library:

2411 ** libgnutls: Fix DSA key generation.
2412 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2414 ** libgnutls: Check expiration/activation time on untrusted certificates.
2415 Merged from stable branch. Reported by Romain Francoise
2416 <romain@orebokech.com>. This changes the semantics of
2417 gnutls_x509_crt_list_verify, which in turn is used by
2418 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2419 We add two new gnutls_certificate_status_t codes for reporting the new
2420 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2421 We also add a new gnutls_certificate_verify_flags flag,
2422 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2423 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2425 ** lib: Linker version scripts reduces number of exported symbols.
2426 The linker version script now lists all exported ABIs explicitly, to
2427 avoid accidentally exporting unintended functions. Compared to
2428 before, most symbols beginning with _gnutls* are no longer exported.
2429 These functions have never been intended for use by applications, and
2430 there were no prototypes for these function in the public header
2431 files. Thus we believe it is possible to do this without incrementing
2432 the library ABI version which normally has to be done when removing an
2435 ** lib: Limit exported symbols on systems without LD linker scripts.
2436 Before all symbols were exported. Now we limit the exported symbols
2437 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2438 _gnutls*. This is a superset of the actual supported ABI, but still
2439 an improvement compared to before. This is implemented using Libtool
2440 -export-symbols-regex. It is more portable than linker version
2443 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2444 This should have been done in the last release.
2446 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2447 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2448 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2450 ** doc: Improved sections for the info manual.
2451 We now follow the advice given by the texinfo manual on which
2452 directory categories to use. In particular, libgnutls moved from the
2453 'GNU Libraries' section to the 'Software libraries' and the command
2454 line tools moved from 'Network Applications' to 'System

2467 ** libgnutls: Applied patch by Cedric Bail to add functions
2468 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2470 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

2482 It is currently only used by the core library. This will enable a new
2483 domain 'gnutls' for translations of the command line tools.
2485 ** Corrected possible memory corruption on signature verification failure.
2486 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2488 ** API and ABI modifications:
2489 gnutls_x509_crt_verify_hash: ADDED
2490 gnutls_x509_crt_get_verify_algorithm: ADDED
2492 * Version 2.7.6 (released 2009-02-27)
2494 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2495 This applies both to generating certificates and certificate requests.
2497 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2499 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2500 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2501 be used for chain verification.
2503 ** gnutls-serv: No longer disable MAC padding by default.
2504 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2506 ** gnutls-cli: Certificate information output format changed.
2507 The tool now uses libgnutls' functions to print certificate
2508 information. This avoids code duplication.
2510 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2511 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2512 They can be used to override the default certificate chain validation
2515 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2516 specify the client hello message record version. Used to overcome buggy
2517 TLS servers. Report by Martin von Gagern.
2519 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2521 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2523 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2525 ** API and ABI modifications:
2526 No changes since last version.
2528 * Version 2.7.5 (released 2009-02-06)
2530 ** libgnutls: Accept chains where intermediary certs are trusted.
2531 Before GnuTLS needed to validate the entire chain back to a
2532 self-signed certificate. GnuTLS will now stop looking when it has
2533 found an intermediary trusted certificate. The new behaviour is
2534 useful when chains, for example, contains a top-level CA, an
2535 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2536 To avoid chain validation errors due to the RSA-MD5 cert, you can
2537 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2538 The signature on trusted certificates are not checked, so the chain
2539 has a chance to validate correctly. Reported by "Douglas E. Engert"
2540 <deengert@anl.gov> in
2541 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2543 ** libgnutls: result_size in gnutls_hex_encode now holds
2544 the size of the result. Report by John Brooks <special@dereferenced.net>.
2546 ** libgnutls: gnutls_handshake when sending client hello during a
2547 rehandshake, will not offer a version number larger than the current.
2548 Reported by Tristan Hill <stan@saticed.me.uk>.
2550 ** libgnutls: Permit V1 Certificate Authorities properly.
2551 Before they were mistakenly rejected even though
2552 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2553 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2554 "Douglas E. Engert" <deengert@anl.gov> in
2555 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2557 ** API and ABI modifications:
2558 No changes since last version.
2560 * Version 2.7.4 (released 2009-01-07)
2562 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2563 This is a bugfix -- the previous attempt to do this from internal x509
2564 certificate verification procedures did not return the correct value
2565 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2566 <dkg@fifthhorseman.net> in
2567 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2568 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2569 Gillmor <dkg@fifthhorseman.net>.
2571 ** libgnutls: New interface to get key id for certificate requests.
2572 Patch from David Marín Carreño <davefx@gmail.com> in
2573 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2575 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2577 ** certtool: --verify-chain now prints results of using library verification.
2578 Earlier, certtool --verify-chain used its own validation algorithm
2579 which wasn't guaranteed to give the same result as the libgnutls
2580 internal validation algorithm. Now this command print a new final
2581 line with header 'Chain verification output:' that contains the result
2582 from using the internal verification algorithm on the same chain.
2584 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2586 ** API and ABI modifications:
2587 gnutls_x509_crq_get_key_id: ADDED.
2589 * Version 2.7.3 (released 2008-12-10)
2591 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.

2597 ** libgnutls: Libgcrypt initialization changed.
2598 If libgcrypt has not already been initialized, GnuTLS will now
2599 initialize libgcrypt with disabled secure memory. Initialize
2600 libgcrypt explicitly in your application if you want to enable secure
2601 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2602 allocation functions, which doesn't use secure memory, so there is no
2603 real change in behaviour.
2605 ** libgnutls: Fix memory leak in PSK authentication.
2606 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2607 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2609 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2611 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2612 It needs to be invoked before libgcrypt is initialized.
2614 ** gnutls-cli: Return non-zero exit code on error conditions.
2616 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2618 ** tests: Added chainverify self-test that tests X.509 chain verifications.
2620 ** API and ABI modifications:
2621 No changes since last version.

2625 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2626 The flaw makes it possible for man in the middle attackers (i.e.,
2627 active attackers) to assume any name and trick GnuTLS clients into
2628 trusting that name. Thanks for report and analysis from Martin von
2629 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]

2636 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2637 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2638 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2639 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
2640 work but are deprecated.

2760 ** libgnutls: Corrected double free on signature verification failure.
2761 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2762 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2764 ** libgnutls: Fix DSA key generation.
2765 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2766 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2767 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2769 ** libgnutls: Check expiration/activation time on untrusted certificates.
2770 Reported by Romain Francoise <romain@orebokech.com>. Before the
2771 library did not check activation/expiration times on certificates, and
2772 was documented as not doing so. We have realized that many
2773 applications that use libgnutls, including gnutls-cli, fail to perform
2774 proper checks. Implementing similar logic in all applications leads
2775 to code duplication. Hence, we decided to check whether the current
2776 time (as reported by the time function) is within the
2777 activation/expiration period of certificates when verifying untrusted
2780 This changes the semantics of gnutls_x509_crt_list_verify, which in
2781 turn is used by gnutls_certificate_verify_peers and
2782 gnutls_certificate_verify_peers2. We add two new
2783 gnutls_certificate_status_t codes for reporting the new error
2784 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2785 add a new gnutls_certificate_verify_flags flag,
2786 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2789 More details about the vulnerabilities will be posted at
2790 <http://www.gnu.org/software/gnutls/security.html>.
2792 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2793 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2794 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2796 ** tests: Fix linking of tests/openpgp/keyring self-test.
2797 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2799 ** API and ABI modifications:
2800 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2801 gnutls_certificate_verify_peers: Likewise.
2802 gnutls_certificate_verify_peers2: Likewise.
2803 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2804 GNUTLS_CERT_EXPIRED: ADDED.
2805 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2807 * Version 2.6.5 (released 2009-04-11)
2809 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2810 specify the client hello message record version. Used to overcome buggy
2811 TLS servers. Report by Martin von Gagern.
2813 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2814 Libtasn1 0.3.4 or later is required. This is to align with the
2815 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2817 ** API and ABI modifications:
2818 No changes since last version.
2820 * Version 2.6.4 (released 2009-02-06)
2822 ** libgnutls: Accept chains where intermediary certs are trusted.
2823 Before GnuTLS needed to validate the entire chain back to a
2824 self-signed certificate. GnuTLS will now stop looking when it has
2825 found an intermediary trusted certificate. The new behaviour is
2826 useful when chains, for example, contains a top-level CA, an
2827 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2828 To avoid chain validation errors due to the RSA-MD5 cert, you can
2829 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2830 The signature on trusted certificates are not checked, so the chain
2831 has a chance to validate correctly. Reported by "Douglas E. Engert"
2832 <deengert@anl.gov> in
2833 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2835 ** libgnutls: result_size in gnutls_hex_encode now holds
2836 the size of the result. Report by John Brooks <special@dereferenced.net>.
2838 ** libgnutls: gnutls_handshake when sending client hello during a
2839 rehandshake, will not offer a version number larger than the current.
2840 Reported by Tristan Hill <stan@saticed.me.uk>.
2842 ** libgnutls: Permit V1 Certificate Authorities properly.
2843 Before they were mistakenly rejected even though
2844 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2845 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2846 "Douglas E. Engert" <deengert@anl.gov> in
2847 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2849 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2850 This is a bugfix -- the previous attempt to do this from internal x509
2851 certificate verification procedures did not return the correct value
2852 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2853 <dkg@fifthhorseman.net> in
2854 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2855 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn

2889 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2890 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2891 problem for certificate chains that contained just one self-signed
2892 certificate. Reported by Michael Meskes <meskes@debian.org> in

2933 ** libgnutls-openssl: fix out of bounds access.
2934 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2935 from Thomas Viehmann <tv@beamnet.de>.
2937 ** certtool: Use inet_pton for parsing IPv6 addresses.
2939 ** Major changes compared to the v2.4 branch:
2941 *** Added API to replace and update the crypto backend.
2943 *** certtool: can add several subject alternative names via template file.
2945 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2947 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2948 either set or append alternative names. It can also handle binary structures
2949 such as IP addresses.
2951 *** libgnutls: New function to set minimum acceptable SRP bits.
2952 The function is gnutls_srp_set_prime_bits.
2954 *** libgnutls: Add interface to deal with public key and signature algorithms.
2955 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2956 gnutls_sign_list, and gnutls_sign_get_id.
2958 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2959 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2961 *** libgnutls: New API to get a string corresponding to a error symbol.
2962 The function is gnutls_strerror_name.
2964 *** libgnutls: New API to set the public parameters in a certificate request
2965 *** from a private key.
2966 The function is gnutls_x509_crq_set_key_rsa_raw.
2968 *** libgnutls: New API to set a callback to extract TLS Finished data.
2969 The function to register is gnutls_session_set_finished_function and
2970 it takes a callback of the gnutls_finished_callback_func type.
2972 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2974 *** libgnutls: New interface to register a new TLS extension handler.
2975 The new function gnutls_ext_register can be used to register handlers
2976 for specific TLS extension types. The callback functions have the new
2977 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2978 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2981 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2982 The function is gnutls_register_md5_handler. When libgcrypt is in
2983 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2986 *** API/ABI changes in GnuTLS 2.6
2987 No functions have been removed or modified. The library should be
2988 fully backwards compatible on both the source and binary level.
2990 A new header file <gnutls/crypto.h> have been added. It contains
2991 definitions related to replacing the internal crypto functionality.
2992 All definitions and the header itself is experimental but supported.
2994 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2995 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2996 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2998 The following functions have been added to libgnutls:

3109 gnutls_sign_get_name: ADDED
3110 gnutls_pk_get_name: ADDED
3112 * Version 2.5.6 (released 2008-09-08)
3114 ** libgnutls: Add interface to deal with public key and signature algorithms.
3115 The functions are called gnutls_pk_list, gnutls_pk_get_id,
3116 gnutls_sign_list, and gnutls_sign_get_id. Suggested by Sam
3117 Varshavchik <mrsam@courier-mta.com>.
3119 ** libgnutls: Refactor and clean up some code.
3121 ** libgnutls: Fix compile error with Sun CC.
3123 ** gnutls-cli: Improve --list output to include public key and signature algs.
3125 ** gnutls-cli, gnutls-serv: Remove --copyright parameter.
3126 Use standard --version to get license info.
3128 ** gnutls-cli.1: Document all new parameters.
3129 Thanks to James Westby <jw+debian@jameswestby.net>.

3137 gnutls_sign_list: ADDED
3138 gnutls_sign_get_id: ADDED
3140 * Version 2.5.5 (released 2008-08-29)
3142 ** libgnutls: New API to get a string corresponding to a error symbol.
3143 The function is gnutls_strerror_name.
3145 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
3146 Reported by "jth.net ApS" <info@jth.net>.
3148 ** libgnutls: Fix segmentation fault when generating private keys.
3149 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3151 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
3152 The code has not worked since v0.9.0 and apparently nobody has missed
3153 it, so we decided to remove the code rather than fix it. If you have
3154 old certificate chains stored in PKCS#7 format, you can convert them
3155 to a list of PEM certificates by using 'certtool --p7-info'. Reported
3156 by Christian Grothoff <christian@grothoff.org>.
3158 ** opencdk: Parse (but not decrypt) encrypted secret keys.
3159 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3161 ** libgnutls: Fix many warnings.
3163 ** Included copy of libtasn1 is upgraded to version 1.5.

3172 ** Fix secure memory initialization of libgcrypt.
3173 Reported by Joe Orton <joe@manyfish.co.uk> in
3174 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
3177 Reference to NIST SP 800-57 in the manual on key size recommendations.
3178 Added 'Since:' tags to new APIs for gtk-doc.
3180 ** API and ABI modifications:
3181 No changes since last version.
3183 * Version 2.5.3 (released 2008-08-14)
3185 ** libgnutls: New API to set the public parameters in a certificate request
3186 ** from a private key.
3187 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
3188 discussion with "Zach C." <fxchip@gmail.com>.
3190 ** libgnutls: New API to set a callback to extract TLS Finished data.
3191 The function to register is gnutls_session_set_finished_function and
3192 it takes a callback of the gnutls_finished_callback_func type.
3194 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
3195 Reported in <https://savannah.gnu.org/support/?106453>.
3197 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3198 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3199 names are mapped to the new names in compat.h. These mappings will
3200 likely be removed more quickly than other mappings in that file due to
3201 the namespace violation.
3203 ** libgnutlsxx: Make it build when SRP is disabled.
3205 ** doc: Add doxygen files in doc/doxygen/.
3207 ** API and ABI modifications:
3208 gnutls_x509_crq_set_key_rsa_raw: ADDED
3209 gnutls_session_set_finished_function: ADDED
3210 gnutls_finished_callback_func: ADDED
3211 GNUTLS_MASTER_SIZE: ADDED
3212 GNUTLS_RANDOM_SIZE: ADDED
3213 TLS_MASTER_SIZE: DEPRECATED
3214 TLS_RANDOM_SIZE: DEPRECATED
3216 * Version 2.5.2 (released 2008-07-08)
3218 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3219 The prime and generator was swapped.
3221 ** libgnutls: New interface to register a new TLS extension handler.
3222 The new function gnutls_ext_register can be used to register handlers
3223 for specific TLS extension types. The callback functions have the new
3224 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3225 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3228 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3229 This was made possible by using the new gnutls_ext_register interface.
3230 The TLS/IA functionality has only been supported through the
3231 libgnutls-extra library, so it makes sense for the code to belong
3234 ** API and ABI modifications:
3235 gnutls_ext_recv_func: ADDED
3236 gnutls_ext_send_func: ADDED
3237 gnutls_ext_parse_type_t: ADDED
3238 gnutls_ext_register: ADDED
3240 * Version 2.5.1 (released 2008-07-02)
3244 ** API and ABI modifications:
3245 No changes since last version.
3247 * Version 2.5.0 (released 2008-07-02)
3249 ** Port fixes from v2.4.1 release, see below.
3251 ** Added API to replace and update the crypto backend.
3252 The header gnutls/crypto.h is now officially supported, and declares
3255 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3257 ** Update gnulib and translations.
3258 The gnulib gc crypto code has been removed since it was never finished
3259 and is no longer even used. An internal non-libgcrypt crypto
3260 implementation may be added in the future, but we'll decide that later
3263 ** API and ABI modifications:
3264 gnutls_crypto_bigint_register2: ADDED.
3265 gnutls_crypto_cipher_register2: ADDED.
3266 gnutls_crypto_digest_register2: ADDED.
3267 gnutls_crypto_mac_register2: ADDED.
3268 gnutls_crypto_pk_register2: ADDED.
3269 gnutls_crypto_rnd_register2: ADDED.
3270 gnutls_crypto_single_cipher_register2: ADDED.
3271 gnutls_crypto_single_digest_register2: ADDED.
3272 gnutls_crypto_single_mac_register2: ADDED.
3274 * Version 2.4.3 (released 2009-02-06)
3276 ** libgnutls: Accept chains where intermediary certs are trusted.
3277 Before GnuTLS needed to validate the entire chain back to a
3278 self-signed certificate. GnuTLS will now stop looking when it has
3279 found an intermediary trusted certificate. The new behaviour is
3280 useful when chains, for example, contains a top-level CA, an
3281 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3282 To avoid chain validation errors due to the RSA-MD5 cert, you can
3283 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3284 The signature on trusted certificates are not checked, so the chain
3285 has a chance to validate correctly. Reported by "Douglas E. Engert"
3286 <deengert@anl.gov> in
3287 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3289 ** libgnutls: Permit V1 Certificate Authorities properly.
3290 Before they were mistakenly rejected even though
3291 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3292 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
3293 "Douglas E. Engert" <deengert@anl.gov> in
3294 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3296 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3297 This is a bugfix -- the previous attempt to do this from internal x509
3298 certificate verification procedures did not return the correct value
3299 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
3300 <dkg@fifthhorseman.net> in
3301 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

3311 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
3312 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
3313 problem for certificate chains that contained just one self-signed
3314 certificate. Reported by Michael Meskes <meskes@debian.org> in

3317 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
3318 The flaw makes it possible for man in the middle attackers (i.e.,
3319 active attackers) to assume any name and trick GnuTLS clients into
3320 trusting that name. Thanks for report and analysis from Martin von

3362 to hash some data using a libgcrypt handle that had been deallocated.

3383 ** API and ABI modifications:
3384 No changes since last version.
3386 * Version 2.4.0 (released 2008-06-19)
3388 ** Major changes compared to the v2.2 branch:
3390 *** The OpenPGP sub-system has been improved and now supports subkeys.
3392 *** The PSK sub-system has been improved and now supports password
3393 *** derivation and PSK identity hints.
3394 The password derivation algorithms support is documented in
3395 draft-ietf-netconf-tls-02.txt.
3397 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3398 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3399 The old parameters will continue to work for some time.
3401 *** Certtool now confirm passwords and changes permissions of private key files.
3403 *** The default handshake size limit has been increased to 48kb.
3404 It appears as if some valid handshakes are large due to sending many
3405 CA certificates. (The earlier limit was 16kb.)
3407 *** LZO compression is now disabled by default.
3408 The main reason is that LZO compression in TLS is not standardized,
3409 but license compatiblity issues with minilzo triggered us to make this
3412 *** Improvements for cross-compilation to Windows and OpenWRT.
3414 *** The look of the GTK-DOC manual has been improved.
3415 Major developer visible changes compared to the v2.2 branch:
3417 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3419 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3420 *** elements from the certificate credentials structure.
3421 Thanks to Joe Orton.
3423 *** New APIs to improve working with username/passwords and PSK.
3425 *** Names of constants to affect certificate printing changed.
3426 The constants are used for OpenPGP too, which the names didn't
3427 reflect, so the following name change has been made:
3430 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3431 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3432 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3434 The old names will be mapped to the new names for some time.
3436 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3437 *** gnutls_openpgp_privkey_get_key_id.
3438 A compatibility mapping exists to avoid breaking API backwards
3441 *** Replaced all uses of alloca with malloc and free.
3443 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3444 We have been unable to find a documented rationale for this practice.
3446 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3448 *** API/ABI changes in GnuTLS 2.4
3449 All OpenPGP related functions have been moved from libgnutls-extra to
3450 libgnutls, and several new functions have been added (see below).
3451 Before making the release, we discussed whether moving functions from
3452 libgnutls-extra to libgnutls would require us to increment the ABI
3453 version, but the general opinion was that this would not be required.
3454 All older functions continue to work the same. We are open to the
3455 possibility that this decision will lead to problem on some platform,
3456 and if it turns out that the Right Thing should have been to increment
3457 the shared library version, we would need to release an update within
3458 the 2.4.x branch that increments the shared library version.
3460 This release adds the following functions:
3462 gnutls_psk_client_get_hint
3463 gnutls_psk_set_server_credentials_hint
3464 gnutls_psk_netconf_derive_key
3466 Used to get/set the PSK identity hint, and derive PSK keys from
3467 passwords a'la netconf.
3469 gnutls_x509_dn_deinit
3470 gnutls_x509_dn_export
3471 gnutls_x509_dn_import
3474 Used to handle X.509 Certificate DN's directly.
3478 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3481 gnutls_certificate_get_x509_cas
3482 gnutls_certificate_get_x509_crls
3483 gnutls_certificate_get_openpgp_keyring
3485 Functions for direct access to credential elements.
3487 gnutls_openpgp_crt_get_auth_subkey

3525 gnutls_openpgp_privkey_get_subkey_revoked_status
3526 gnutls_openpgp_privkey_set_preferred_key_id
3528 New OpenPGP related functions.
3530 The function gnutls_openpgp_crt_get_key_id is the same as the old
3531 from gnutls_openpgp_crt_get_id, see above.
3533 The release also adds a new header file 'gnutls/crypto.h', however it
3534 is currently not used.

3570 ** doc/: Add psktool to info index. Some minor cleanups.
3572 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3574 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3575 The file suppresses the known libgcrypt memory leaks, so they aren't

3606 message is sent if the application has specified a PSK identity hint
3607 using gnutls_psk_set_server_credentials_hint.
3609 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3610 The function gnutls_psk_netconf_derive_key supports the PSK key
3611 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3614 *** psktool: Support new --netconf-hint to generate PSK key from password.
3615 Uses the Netconf algorithm to derive PSK key from password.
3617 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3619 *** gnutls-cli: Always support PSK modes, through a callback.
3620 The callback will derive a PSK key using Netconf algorithm. It will
3621 print the PSK identity hint to help the user.
3623 *** New PSK example client and server.
3624 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3626 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3627 The code didn't work properly on platforms where 'char' is unsigned,
3628 when you set version 0. Reported by Laurence Withers
3629 <l@lwithers.me.uk> in
3630 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
3632 ** libgnutls-openssl: added RAND_pseudo_bytes API.
3633 Patch from Robert Millan <rmh@aybabtu.com>.
3635 ** API and ABI modifications:
3636 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
3637 gnutls_psk_client_get_hint: ADDED.
3638 gnutls_psk_set_server_credentials_hint: ADDED.
3639 gnutls_psk_netconf_derive_key: ADDED
3641 * Version 2.3.11 (released 2008-05-20)
3643 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3644 The flaw would result in incorrectly terminated sessions with the
3645 error "Decryption has failed" when the server sends a small packet
3646 (typically when the session is closed). Reported by Andreas Metzler
3647 <ametzler@downhill.at.eu.org> in
3648 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3650 ** Don't use gnulib headers when building C++ library.
3651 Fixes builds under Windows.
3653 ** Make umask a requirement.
3654 We don't know of any system that lacks it, even GNU CoreUtils use it
3657 ** Update gnulib files.
3658 Fixes a problem where it pulled in a replacement for memcmp under
3659 MinGW, which caused the C++ example to fail to build.
3661 ** API and ABI modifications:
3662 No changes since last version.
3664 * Version 2.3.10 (released 2008-05-19)
3666 ** Added wide wildcard hostname matching.
3667 Tiny patch by Jean-Philippe Garcia Ballester.
3669 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3670 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3671 which allowed the bugs to be reproduced and fixed easily. Patches
3672 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3673 with more details about these vulnerabilities will be added to
3674 <http://www.gnu.org/software/gnutls/security.html>
3676 *** [GNUTLS-SA-2008-1-1]
3677 *** libgnutls: Fix crash when sending invalid server name.
3678 The crash can be triggered remotely before authentication, which can
3679 lead to a Daniel of Service attack to disable the server. The bug
3680 cause gnutls to store more session resumption data than what was
3681 allocated for, thus overwriting unallocated memory.
3683 *** [GNUTLS-SA-2008-1-2]
3684 *** libgnutls: Fix crash when sending repeated client hellos.
3685 The crash can be triggered remotely before authentication, which can
3686 lead to a Daniel of Service attack to disable the server. The bug
3687 triggers a null-pointer dereference.
3689 *** [GNUTLS-SA-2008-1-3]
3690 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3691 The crash can be triggered remotely before authentication, which can
3692 lead to a Daniel of Service attack to disable the server. The bug
3693 cause gnutls to read memory beyond the end of the received record.
3695 ** libgnutlsxx: Updated API according to patches from Eduardo
3696 Villanueva Che (discussion at
3697 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3699 ** Use umask to restrict permissions to owner before creating a file.
3701 ** API and ABI modifications:
3702 No changes since last version.
3704 * Version 2.3.9 (released 2008-05-16)
3706 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3707 Based on report and tiny patches from
3708 <jared.jennings.ctr@eglin.af.mil>, see
3709 <https://savannah.gnu.org/support/index.php?106342>.
3711 ** libgnutls: Translation fixes.
3713 ** gnutls-cli: Fix so that PSK authentication works.
3714 Also improve manual to give example for gnutls-cli PSK authentication.
3716 ** certtool: Encrypting a private key now require a confirmed password.
3717 Before './certtool -k -8' would merely ask for a password once.
3718 Reported by Daniel 'NebuchadnezzaR' Dehennin
3719 <nebuchadnezzar@asgardr.info> see
3720 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3722 ** certtool: When writing private keys to files, change permissions of file.
3723 Now the file which the private key is saved to is chmod'ed 0600.
3724 Reported by martin f krafft <madduck@debian.org> see
3725 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3727 ** guile: Fix -fgnu89-inline test.
3729 ** Removed --enable-profile-mode.
3730 The code linked gnutls with the libfc project (Function Check) which
3731 appears to have been stalled since around 2002.
3733 ** Clean up header file checks by ./configure.
3735 ** Update of gnulib files.
3737 ** API and ABI modifications:
3738 No changes since last version.
3740 * Version 2.3.8 (released 2008-04-29)
3742 ** libgnutls: Increase default handshake packet size limit to 48kb.
3743 The old limit was 16kb and some servers send huge list of trusted CAs,
3744 thus running into the limit. FYI, applications can further increase
3745 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3746 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3747 <marc@mclemente.net> for reporting and providing test servers.
3749 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3750 Returned when the handshake data size is too large. Before
3751 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3754 ** libgnutls: Hide definitions in crypto.h.
3755 We have decided that the APIs defined in crypto.h are not stable
3756 enough for v2.4, so don't use any of those functions.
3758 ** gnutls-cli: exit when hostname doesn't match certificate.
3759 Use --insecure to avoid hostname comparison.
3761 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3762 The reason is to align terminology with OpenPGP, which doesn't use
3763 DER. The old parameters will continue to work for some time.
3765 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3767 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3769 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3770 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3771 vasprintf symbol from the libgcrypt library which caused problems.
3773 ** Update of gnulib files.
3775 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3777 ** API and ABI modifications:
3778 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3780 * Version 2.3.7 (released 2008-04-21)
3782 ** opencdk now properly sets the key usage bits into openpgp keys.
3784 ** gnutls-cli: Fix crash on TLS handshake failures.
3785 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3786 This is similar to <http://bugs.debian.org/429183>.
3788 ** certtool: with --generate-request and newly generated keys, print the key.
3790 ** Build fixes for MinGW.
3791 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3792 with -lws2_32 when needed. Use ASCII only isprint() when printing
3793 X.509 certificate information, to avoid non-ASCII but printable
3794 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3797 ** Update internal copy of libtasn1 to version 1.4.
3799 ** API and ABI modifications:
3800 No changes since last version.
3802 * Version 2.3.6 (released 2008-04-17)
3804 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3805 ** Improve documentation for gnutls_x509_crq_sign2.
3806 Based on report from "John Brooks" <aspecialj@gmail.com> in
3807 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3809 ** tests/pathlen: run diff without parameters to improve portability.
3810 Based on HPUX build hints in
3811 <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>.
3813 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3814 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3815 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3817 ** Remove all uses of gnutls_alloca/gnutls_afree.
3818 Use normal gnutls_malloc instead. One reason is increased portability
3819 to Windows, the other is that several of the uses may be unsafe
3820 because the size of data allocated could be large. Reported by
3821 Massimo Gaspari <massimo.gaspari@alice.it> in
3822 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3824 ** Build Guile code with -fgnu89-inline only when supported.
3825 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3826 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3828 ** Several GTK-DOC related fixes.
3830 ** Clean up OpenCDK related code.
3831 GnuTLS now requires its internal OpenCDK code rather than the external
3832 GPL library OpenCDK. Unfortunately, we don't have resources to
3833 maintain an external library (help welcome).
3835 ** API and ABI modifications:
3836 No changes since last version.
3838 * Version 2.3.5 (released 2008-04-14)
3840 ** Build fix for MinGW and --disable-shared.
3841 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3842 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3844 ** Document how to generate CRLs.
3845 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3847 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3849 ** Several minor fixes in the OpenPGP interface.
3850 Thanks to Daniel Kahn Gillmor.
3852 ** Fix fopen file descriptor leak in PSK server code.
3853 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3854 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3856 ** Translations files not stored directly in git to avoid merge conflicts.
3858 ** New APIs to let applications replace the RNG used.
3859 Update all RNG callers in the code to use the new interface.
3861 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3863 ** Update gnulib files.
3865 ** API and ABI modifications:
3866 gnutls_crypto_rnd_register: ADDED
3867 gnutls_rnd_level_t: ADDED
3868 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3869 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3870 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3871 gnutls_crypto_rnd_st: ADDED
3872 GNUTLS_DIG_SHA224: ADDED
3873 GNUTLS_SIGN_RSA_SHA224: ADDED
3874 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3876 * Version 2.3.4 (released 2008-03-19)
3878 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3879 They weren't renamed in the public header file.
3881 ** Added functions to register a cipher/mac/digest. This allows to
3882 override the included ones.
3884 ** Fix a bunch of compiler warnings.
3886 ** API and ABI modifications:
3887 gnutls_crypto_cipher_st: ADDED
3888 gnutls_crypto_mac_st: ADDED
3889 gnutls_crypto_digest_st: ADDED
3890 gnutls_crypto_cipher_register: ADDED
3891 gnutls_crypto_mac_register: ADDED
3892 gnutls_crypto_digest_register: ADDED
3893 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3895 * Version 2.3.3 (released 2008-03-10)
3897 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3898 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3900 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3901 We could not find any modern justification for enabling these flags by
3902 default. If you know of some platform that needs one of the flags to
3903 work properly, please let us know. (Actually introduced in v2.3.0 but
3904 not documented until now.)
3906 ** Importing many CA certificates are now considerably faster.
3907 This affect gnutls_certificate_set_x509_trust_mem,
3908 gnutls_certificate_set_x509_trust, and
3909 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3910 from O(2*n^2) to O(n). When adding 206 files containing 408
3911 certificates, using gnutls_certificate_set_x509_trust_file, the time
3912 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3913 to trigger the problem. See also
3914 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3916 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3917 ** to be explicit that it takes zero terminated data.
3919 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3921 ** Documentation fixes for the GTK-DOC manual.
3923 ** Fix compilation error related to __FUNCTION__ on some systems.
3924 Reported by Tim Mooney, see
3925 <https://savannah.gnu.org/support/?106267>.
3927 ** Updated translations.
3929 ** Update gnulib files.
3931 ** API and ABI modifications:
3932 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3933 and char* instead of void* for output buffer.
3935 * Version 2.3.2 (released 2008-02-26)
3937 ** Fix srcdir!=objdir failure in openpgpself test.
3939 ** Improved API documentation output from GTK-DOC.
3941 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3943 ** Renamed gnutls_certificate_export_x509_cas and friends.
3944 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3946 ** Internal header files cleanup.
3948 ** API and ABI modifications:
3949 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3950 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3951 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3952 gnutls_x509_dn_export: ADDED
3954 * Version 2.3.1 (released 2008-02-21)
3956 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3957 The included copy of OpenCDK has been stripped down and re-licensed
3960 ** Cipher priority string handling now handle strings that starts with NULL.
3961 Thanks to Laurence Withers <l@lwithers.me.uk>.
3963 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3965 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3968 ** Increased the default certificate verification chain limits and allowed
3969 for checks without limitation.
3971 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3972 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3973 strings and return the proper size.
3975 ** Add section 'On Record Padding' to the manual.
3976 This collects all problems related to record padding with
3977 Nokia/Sony-Ericsson phones that we know about.
3979 ** Several improvements in the OpenPGP authentication.
3980 Now subkeys can be used for authentication, according to
3981 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3983 ** certtool can print information on OpenPGP certificates and keys.
3985 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3988 ** Added gnutls_certificate_export_x509_cas and other functions to
3989 export elements from the certificate credentials structure. Based on
3990 suggestion from Joe Orton.
3993 Clarify that srp_base64 is not the same as normal base64.
3995 ** Fix non-portable use of brace expansion in makefiles.
3997 ** API and ABI modifications:
3998 gnutls_certificate_export_x509_cas: ADDED
3999 gnutls_certificate_export_x509_crls: ADDED
4000 gnutls_certificate_export_openpgp_keyring: ADDED
4001 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
4002 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
4003 gnutls_openpgp_crt_get_revoked_status: ADDED
4004 gnutls_openpgp_crt_get_subkey_count: ADDED
4005 gnutls_openpgp_crt_get_subkey_idx: ADDED
4006 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
4007 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
4008 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
4009 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED

4039 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
4040 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
4041 old GNUTLS_X509_CRT_UNSIGNED_FULL.
4043 * Version 2.3.0 (released 2008-01-08)
4045 ** LZO compression is now disabled by default.
4046 The reason is that LZO compression is not standardized in TLS. If you
4047 wish to experiment with it, you will have to supply --with-lzo when
4048 invoking ./configure. The internal copy of minilzo is no longer
4049 included with GnuTLS, so you will need to install liblzo or liblzo2 on
4050 your system to have --with-lzo to be effective.
4052 ** More than one server name field is now sent to the server properly.
4053 Thanks to mark.phillips@virgin.net.
4055 ** Fixes the post_client_hello_function(). The extensions are now parsed
4056 in a callback friendly way.
4058 ** Fix for certificate selection in servers with certificate callbacks.
4060 ** Updated translations.
4062 ** Update gnulib files.
4064 ** API and ABI modifications:
4065 No changes since last version.
4067 * Version 2.2.5 (released 2008-05-19)
4069 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
4070 The flaw would result in incorrectly terminated sessions with the
4071 error "Decryption has failed" when the server sends a small packet
4072 (typically when the session is closed). Reported by Andreas Metzler

4097 The crash can be triggered remotely before authentication, which can
4098 lead to a Daniel of Service attack to disable the server. The bug
4099 triggers a null-pointer dereference.
4101 *** [GNUTLS-SA-2008-1-3]
4102 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
4103 The crash can be triggered remotely before authentication, which can
4104 lead to a Daniel of Service attack to disable the server. The bug
4105 cause gnutls to read memory beyond the end of the received record.
4107 ** API and ABI modifications:
4108 No changes since last version.
4110 * Version 2.2.3 (released 2008-05-06)
4112 ** Increase default handshake packet size limit to 48kb.
4113 The old limit was 16kb and some servers send huge list of trusted CAs,
4114 thus running into the limit. FYI, applications can further increase
4115 this limit using gnutls_handshake_set_max_packet_length. Thanks to
4116 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
4117 <marc@mclemente.net> for reporting and providing test servers.
4119 ** Fix compilation error related to __FUNCTION__ on some systems.
4120 Reported by Tim Mooney, see
4121 <https://savannah.gnu.org/support/?106267>.
4123 ** Documented the --priority option to gnutls-cli and gnutls-serv.
4125 ** Fix fopen file descriptor leak in PSK server code.
4126 Thanks to Laurence Withers <l@lwithers.me.uk>, see
4127 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
4129 ** Build Guile code with -fgnu89-inline only when supported.
4130 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
4131 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
4133 ** Make Camellia encryption work.
4134 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
4135 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
4137 ** API and ABI modifications:
4138 No changes since last version.
4140 * Version 2.2.2 (released 2008-02-21)
4142 ** Cipher priority string handling now handle strings that starts with NULL.
4143 Thanks to Laurence Withers <l@lwithers.me.uk>.
4145 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
4148 ** Increased the default certificate verification chain limits and allowed
4149 for checks without limitation.
4151 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
4152 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
4153 strings and return the proper size.
4155 ** API and ABI modifications:
4156 No changes since last version.
4158 * Version 2.2.1 (released 2008-01-17)
4160 ** Prevent linking libextra against previously installed libgnutls.
4161 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
4162 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
4164 ** Fixes the post_client_hello_function(). The extensions are now parsed
4165 in a callback friendly way.
4167 ** Fix for certificate selection in servers with certificate callbacks.
4169 ** API and ABI modifications:
4170 No changes since last version.
4172 * Version 2.2.0 (released 2007-12-14)
4174 ** Update internal copy of libtasn1 to version 1.2.
4176 ** Certtool --verify-chain now handle inputs larger than 64kb.
4177 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
4178 recent versions of libgcrypt. The problem was that Wine with the
4179 libgcrypt RNG generates huge amounts of debugging output.
4181 ** Translation updates.
4182 Added Dutch translation. Updated Polish and Swedish translation.
4184 ** Major changes compared to the v2.0 branch:
4186 *** SRP support aligned with newly published RFC 5054.
4188 *** OpenPGP support aligned with newly published RFC 5081.
4190 *** Support for DSA2 keys.
4192 *** Support for Camellia cipher.
4194 *** Support for Opaque PRF Input extension.
4196 *** PKCS#8 parser now handle DSA keys.
4198 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4199 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4200 versions, such as 2.01 which is included with GnuTLS, is available
4201 under GPLv2 or later. If this incompatibility causes problems, we
4202 recommend you to disable LZO using --without-lzo. LZO compression is
4203 not a standard TLS compression algorithm, so the impact should be
4206 *** Functions for disabling record protocol padding.
4207 Works around bugs on Nokia/Ericsson phones.
4209 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4210 Priorities like "COMPAT" also enables other work arounds, such as
4213 *** Other minor improvements and bug fixes.
4215 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4216 To adapt to changes in the TLS extension specifications for OpenPGP
4217 and SRP, the GnuTLS API had to be modified. This means breaking the
4218 API and ABI backwards compatibility. That is something we try to
4219 avoid unless it is necessary. We decided to also remove the already
4220 deprecated stub functions for X.509 to XML conversion and TLS
4221 authorization (see below) when we had the opportunity.
4223 Generally, most applications does not need to be modified. Just
4224 re-compile them against the latest GnuTLS release, and it should work
4227 Applications that use the OpenPGP or SRP features needs to be
4228 modified. Below is a list of the modified APIs and discussion of what
4229 the minimal things you need to modify in your application to make it
4230 work with GnuTLS 2.2.
4232 Note that GnuTLS 2.2 also introduces new APIs -- such as
4233 gnutls_set_priority() that is superior to
4234 gnutls_set_default_priority() -- that you may want to start using.
4235 However, using those new APIs is not required to use GnuTLS 2.2 since
4236 the old functions continue are still supported. This text only
4237 discuss what you minimally have to modify.
4239 *** XML related changes
4240 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4241 deprecated and only returned an error code since GnuTLS version
4242 1.2.11. Nobody has complained, so users doesn't seem to miss the
4243 functionality. We don't know of any other library to convert X.509
4244 certificates into XML format, but we decided (long ago) that GnuTLS
4245 isn't the right place for this kind of functionality. If you want
4246 help to find some other library to use here, please explain and
4247 discuss your use case on help-gnutls@gnu.org.
4249 *** TLS Authorization related changes
4250 Everything related to TLS authorizations have been removed, they were
4251 only stub functions that returned an error code:
4253 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4254 gnutls_authz_data_format_type_t
4255 gnutls_authz_recv_callback_func
4256 gnutls_authz_send_callback_func
4258 gnutls_authz_send_x509_attr_cert
4259 gnutls_authz_send_saml_assertion
4260 gnutls_authz_send_x509_attr_cert_url
4261 gnutls_authz_send_saml_assertion_url
4263 *** SRP related changes
4264 The callback gnutls_srp_client_credentials_function has a new
4265 prototype, and its semantic has changed. You need to rewrite the
4266 callback, see the updated function documentation and SRP example code
4267 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4270 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4271 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4272 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4273 used. There are #define's to map the old names to the new. You may
4274 run into problems if you have a switch-case with cases for both SRP
4275 alerts, since they are now mapped to the same value. The solution is
4276 to drop the SRP alerts from such switch cases, as they are now
4277 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4279 *** OpenPGP related changes
4280 The function `gnutls_certificate_set_openpgp_keyserver' have been
4281 removed. There is no replacement functionality inside GnuTLS. If you
4282 need keyserver functionality, consider using the GnuPG tools.
4284 All functions, types, and error codes related to OpenPGP trustdb
4285 format have been removed. The trustdb format is a non-standard
4286 GnuPG-specific format, and we recommend you to use key rings instead.
4287 The following have been removed:
4289 gnutls_certificate_set_openpgp_trustdb
4290 gnutls_openpgp_trustdb_init
4291 gnutls_openpgp_trustdb_deinit
4292 gnutls_openpgp_trustdb_import
4293 gnutls_openpgp_key_verify_trustdb
4294 gnutls_openpgp_trustdb_t
4295 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
4297 The following functions has an added parameter of the (new) type
4298 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4299 (binary or base64). The functions are:
4300 gnutls_certificate_set_openpgp_key_file
4301 gnutls_certificate_set_openpgp_key_mem
4302 gnutls_certificate_set_openpgp_keyring_mem
4303 gnutls_certificate_set_openpgp_keyring_file
4305 To improve terminology and align with the X.509 interface, some
4306 functions have been renamed. Compatibility mappings exists. The old
4307 and new names of the affected functions and types are:
4310 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4311 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
4312 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
4313 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
4314 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
4315 gnutls_openpgp_key_init gnutls_openpgp_crt_init
4316 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
4317 gnutls_openpgp_key_import gnutls_openpgp_crt_import
4318 gnutls_openpgp_key_export gnutls_openpgp_crt_export
4319 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
4320 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
4321 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
4322 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
4323 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
4324 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
4325 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
4326 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
4327 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
4328 gnutls_openpgp_send_key gnutls_openpgp_send_cert
4330 ** API and ABI modifications:
4331 No changes since last version.
4333 * Version 2.1.8 (released 2007-12-10)
4335 ** The GPL version has been changed from version 2 to version 3.
4336 This affects the self-tests, command-line tools, the libgnutls-extra
4337 library, the relevant guile parts, and the build environment.
4339 ** Added gnutls_x509_crt_get_subject_alt_name2().
4341 ** Corrected a segfault when setting an empty gnutls_priority_t
4342 at gnutls_priority_set().
4344 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
4345 Fixes a problem with spurious -L/usr/lib additions.
4347 ** API and ABI modifications:
4348 gnutls_x509_crt_get_subject_alt_name2: ADD.
4350 * Version 2.1.7 (released 2007-11-29)
4352 ** PKCS #8 parser can now encode/decode DSA keys.
4354 ** Updated gnutls_set_default_priority2() now renamed to
4355 gnutls_priority_set() and gnutls_priority_set_direct() which
4356 accept a string to indicate preferences of ciphersuite parameters.
4358 ** gnutls-cli and gnutls-serv now have a --priority option to set
4359 the priority string.
4361 ** The gnutls_*_convert_priority() functions were deprecated by
4362 the gnutls_priority_set() and gnutls_priority_set_direct().
4364 ** Internal copy of OpenCDK upgraded to version 0.6.6.

4381 ** Undocumented API and ABI modifications earlier in the 2.1.x series:
4382 GNUTLS_CIPHER_UNKNOWN: ADD.
4383 GNUTLS_CIPHER_CAMELLIA_128_CBC: ADD.

4397 * Version 2.1.6 (released 2007-11-15)
4399 ** Corrected bug in decompression of expanded compression data.
4401 ** Added the --to-p8 option to certtool to convert private keys
4404 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4406 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4409 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4410 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4411 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4412 documented. This caused some problems (e.g., debian #450854). To
4413 avoid backwards compatibility problems, this release revert this
4414 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4415 done in GnuTLS 2.0.x and earlier, and add a new error code
4416 GNUTLS_E_UNKNOWN_ALGORITHM.
4418 ** Fixes several gtk-doc warnings.
4420 ** API and ABI modifications:
4421 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4422 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4423 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4425 * Version 2.1.5 (released 2007-11-01)
4427 ** Fix PKCS#3 parameter export problem.
4429 ** Improve certtool queries, they now print the default value.
4433 ** Update gnulib files.
4435 ** API and ABI modifications:
4436 No changes since last version.
4438 * Version 2.1.4 (released 2007-10-27)
4440 ** Added the --v1 option to certtool, to allow generating X.509
4441 version 1 certificates.
4443 ** certtool: Add option --disable-quick-random to enable the old behaviour
4444 of using /dev/random to generate keys.
4446 ** Added priority functions that accept strings.
4448 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4449 priorities preferences.
4451 ** Added gnutls_record_disable_padding() to allow servers talking to
4452 buggy clients that complain if the TLS 1.0 record protocol padding is
4455 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4456 all supported compatibility options (like disabling padding).
4458 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4459 the format. This makes the interface consistent with the x509 functions.
4461 ** Internal copy of OpenCDK upgraded to version 0.6.5.

4503 This technique may be patented in the future, and it is not of crucial
4504 importance for the Internet community. After deliberation we have
4505 concluded that the best thing we can do in this situation is to
4506 encourage society not to adopt this technique. We have decided to
4507 lead the way with our own actions.

4527 * Version 2.1.2 (released 2007-10-14)
4529 ** Removed all the trustdb code from openpgp authentication.
4530 We now use only the well-specified keyrings.
4532 ** The 256 bit ciphers are not enabled in the default priorities.
4534 ** Added support for DSA2 using libgcrypt 1.3.0.

4571 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4572 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4573 compiled with Camellia support. See the libgcrypt documentation on
4574 how to enable it. Unconditionally disable it using the configure
4575 option --disable-camellia. Fixes #1.

4585 The support is disabled by default. Since no value has been allocated
4586 by the IANA for this extension yet, you will need to provide one
4587 yourself by invoking './configure --enable-opaque-prf-input=42'.
4590 ** Example code: Fix compilation flaw under MinGW.
4592 ** API and ABI modifications:
4593 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
4594 gnutls_oprfi_enable_client: ADD, new function.
4595 gnutls_oprfi_enable_server: ADD, new function.
4597 * Version 2.0.4 (released 2007-11-16)
4599 ** Corrected bug in decompression of expanded compression data.
4601 ** API and ABI modifications:
4602 No changes since last version.
4604 * Version 2.0.3 (released 2007-11-10)
4606 ** This version backports several fixes from the 2.1.x branch.
4608 ** Fixed PKCS #3 parameter export.
4610 ** Added gnutls_record_disable_padding() to allow servers talking to
4611 buggy clients that complain if the TLS 1.0 record protocol padding is
4614 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4615 all supported compatibility options (like disabling padding).
4617 ** Corrected bug which did not allow a server to run without supporting
4620 ** API and ABI modifications:
4621 gnutls_session_enable_compatibility_mode: ADDED
4622 gnutls_record_disable_padding: ADDED
4624 * Version 2.0.2 (released 2007-10-17)
4626 ** TLS authorization support removed.
4627 This technique may be patented in the future, and it is not of crucial
4628 importance for the Internet community. After deliberation we have
4629 concluded that the best thing we can do in this situation is to
4630 encourage society not to adopt this technique. We have decided to
4631 lead the way with our own actions.
4633 ** certtool: Fixed data corruption when using --outder.
4635 ** Fix configure-time Guile detection.
4637 ** API and ABI modifications:
4638 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4639 gnutls_supplemental_data_format_type_t enum type becomes empty.
4641 * Version 2.0.1 (released 2007-09-20)
4643 ** New directory doc/credentials/ with test credentials.
4644 This collects the test credentials from the web page and from src/.
4645 The script gnutls-http-serv has also been moved to that directory.
4647 ** Update SRP extension type and cipher suite with official IANA values.
4648 This breaks backwards compatibility with SRP in older versions of
4649 GnuTLS, but this is intentional to speed up the adoption of the
4650 official values. The old values we used were incorrect.
4652 ** Guile: Fix `x509-certificate-dn-oid'
4654 ** API and ABI modifications:
4655 No changes since last version.
4657 * Version 2.0.0 (released 2007-09-04)
4659 ** Included copy of Libtasn1 upgraded to version 1.1.
4661 ** Disable building of some examples if anonymous ciphers are disabled.
4663 ** Don't build examples for disabled features.
4665 ** API and ABI modifications:
4666 No changes since last version.
4668 * Version 1.7.19 (released 2007-08-27)
4670 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4671 This solves connection problems in mutt, see
4672 <http://bugs.debian.org/439640>.
4674 ** Update gnulib files.
4675 In particular, the getpass module -- with its dependencies on getline,
4676 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4677 library) directory to the gl/ directory (only used by the command line
4678 tools). The reason is that getpass is now only used by the
4679 command-line tools, and reducing the number of gnulib modules linked
4680 to the core library helps portability and reduces size.
4684 ** Disable building of PGP examples if PGP is disabled.
4686 ** Included copy of OpenCDK upgraded to version 0.6.4.
4688 ** API and ABI modifications:
4689 No changes since last version.
4691 * Version 1.7.18 (released 2007-08-16)
4693 ** Install images for the info manual.
4694 This has a side effect of renaming the images. See
4695 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4696 discussions on the approach chosen.
4698 ** Fix pointer mix to variables of different size.
4699 Patch extracted from
4700 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4702 ** Fix warnings during build.
4703 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4705 ** API and ABI modifications:
4706 No changes since last version.
4708 * Version 1.7.17 (released 2007-08-15)
4710 ** New functions to perform external signing.
4711 Set the signing callback function (of the gnutls_sign_func prototype)
4712 using the gnutls_sign_callback_set function. In the callback, you may
4713 find the new functions gnutls_x509_privkey_sign_hash and
4714 gnutls_openpgp_privkey_sign_hash useful. A new function
4715 gnutls_sign_callback_get is also added, to retrieve the function
4716 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4717 comments and testing.
4719 ** New self test of client and server authenticated X.509 TLS sessions.
4720 See tests/x509self.c and tests/x509signself.c. The latter also tests
4721 the new external signing callback interface.
4723 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4724 These two actually describe the outer limits of a range of error codes
4725 reserved to the application. All of the errors are treated as fatal
4726 by the library (it has to since it doesn't know the semantics of the
4727 error codes). This can be useful in callbacks, to signal some
4728 application-specific error condition, which will usually eventually
4729 cause some gnutls API to return the same error code as the callback,
4730 which then can be inspected by the application. Note that error codes
4733 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4734 The RFC is not released yet, and we're approaching a major release so
4735 let's not enable it just yet.
4737 ** Fix namespace so that gnutls_*_t is used consistently.
4738 Before, many places in the GnuTLS code used the old deprecated type
4739 names without the '_t' suffix.
4741 ** Build fixes for Guile code.
4742 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4744 ** More documentation fixes.
4745 In particular, the section headings were modified for casing. By
4746 Ludovic Courtes <ludovic.courtes@laas.fr>.
4748 ** Updated Polish and Swedish translations.
4749 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4750 <po@danielnylander.se>.
4752 ** API and ABI modifications:
4753 gnutls_sign_func: ADD, new type for sign callback.
4754 gnutls_sign_callback_set: ADD, new function to set sign callback.
4755 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4756 gnutls_x509_privkey_sign_hash,
4757 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4758 GNUTLS_E_APPLICATION_ERROR_MIN,
4759 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4761 * Version 1.7.16 (released 2007-08-07)
4763 ** Fix sanity checks and return values in certificate selection.
4764 In some cases, GnuTLS omitted to report suitable error codes when no
4765 suitable certificate was found.
4767 ** Fix gnutls-cli starttls EOF on Mac OS X.
4768 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4770 ** Documentation fixes.
4771 In particular, the section headings were modified for casing. By
4772 Ludovic Courtes <ludovic.courtes@laas.fr>.
4774 ** Update gnulib files.
4776 ** API and ABI modifications:
4777 No changes since last version.
4779 * Version 1.7.15 (released 2007-07-02)
4781 ** Fix self-tests key-id under mingw32.
4783 ** Test that the Guile header files are recent enough to work.
4784 Before we just tested that the command line tool 'guile' was recent
4785 enough, which may not be sufficient if you still have an old
4786 libguile.h header installed.
4788 ** Guile bindings are now installed under $prefix by default.
4789 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4790 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4791 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4792 The default, --with-guile-site-dir, will install the Guile bindings
4793 under $datadir/guile/site. There is a new section 'Guile
4794 Preparations' in the manual that discuss these issues.
4796 ** Fix run-time library path ordering in linking the Guile bindings.
4798 ** Improved manual on downloading, installing, getting help, bug reports etc.
4799 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4801 ** Add Malay message translations.
4802 Thanks to Sharuzzaman Ahmat Raslan <sharuzzaman@myrealbox.com>.
4804 ** API and ABI modifications:
4805 No changes since last version.
4807 * Version 1.7.14 (released 2007-06-26)
4809 ** Don't enable Guile bindings unless we have Guile 1.8 or later.
4810 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4812 ** Fix memory leak during DSA signature verification.
4813 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4815 ** Fix crash in gnutls-cli when TLS handshake fails.
4816 Reported by Marc Haber <mh+debian-bugs@zugschlus.de> and Andreas
4817 Metzler <ametzler@downhill.at.eu.org> via Debian BTS #429183, see

4821 Patch from Timo Schulz <twoaday@freakmail.de> and Ludovic Courtès
4822 <ludovic.courtes@laas.fr>.
4824 ** Fix off-by-one in TLS 1.2 handshake.
4825 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4827 ** Minor Guile binding self-test cleanup.
4828 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4830 ** Update gnulib files.
4832 ** API and ABI modifications:
4833 No changes since last version.
4835 * Version 1.7.13 (released 2007-06-11)
4837 ** OpenCDK copy updated to version 0.6.3.
4839 ** Build fixes for GnuTLS Guile bindings.
4840 Patch from Ludovic Courtès <ludovic.courtes@laas.fr>.
4842 ** Build fix for GTK-DOC manual.
4844 ** Update gnulib files.
4846 ** API and ABI modifications:
4847 No changes since last version.
4849 * Version 1.7.12 (released 2007-06-08)
4851 ** Guile bindings for GnuTLS have been included.
4852 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
4853 new chapter 'Guile Bindings' in the manual.
4855 ** Have PKCS8 parser return better error codes.
4856 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4857 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4858 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4860 ** Fix mem leak for sessions with client authentication via certificates.
4861 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4862 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4865 Reported by Dennis Vshivkov <walrus@amur.ru>, see
4866 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
4867 self-test tests/parse_ca.c to test regressions.
4869 ** Fix build failures related to missing images in manual.
4870 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
4872 ** Update gnulib files.
4874 ** API and ABI modifications:
4875 No changes since last version.
4877 * Version 1.7.11 (released 2007-05-26)
4879 ** Include opencdk.h in the release.
4880 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4882 ** API and ABI modifications:
4883 No changes since last version.
4885 * Version 1.7.10 (released 2007-05-25)
4887 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4888 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4890 ** Update of gnulib files.
4892 ** GnuTLS is now developed in GIT instead of CVS.
4893 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4895 ** API and ABI modifications:
4896 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4897 gnutls_x509_crt_get_raw_dn: ADD.
4899 * Version 1.7.9 (released 2007-05-12)
4901 ** X.509 certificates are preferred over OpenPGP keys.
4902 This is a change in the semantics of gnutls_set_default_priority.
4904 ** The included copy of OpenCDK has been updated to 0.6.1.
4905 There has been some API changes in OpenCDK, and the GnuTLS layer have
4906 been modified as well. Note that while there are API/ABI incompatible
4907 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4908 its API/ABI have not changed. From this version on, GnuTLS requires
4909 OpenCDK 0.6.0 or later.
4911 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4913 ** Change certtool's default serial number from 0 to a time-based value.
4915 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4916 Before, we remove the parameters field, which resulted in a slightly
4917 different DER encoding which in turn caused signature verification
4918 failures of GnuTLS-generated RSA certificates in some other
4919 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4920 you read, this may or may not be correct, but our new behaviour appear
4921 to be consistent with other widely used implementations.
4923 ** Fix mem leaks in gnutls_x509_crt_print.
4925 ** API and ABI modifications:
4926 No changes since last version.
4928 * Version 1.7.8 (released 2007-04-16)
4930 ** Added examples for the authorization extension.
4931 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4933 ** The examples only use gnutls_set_default_priority().
4934 The exception is when DH_ANON is needed.
4936 ** Improve gnutls_set_default_priority() priorities.
4937 The new approach is for it to try and negotiate all secure and
4938 standard mechanisms available. Currently, DH_ANON ciphersuites and
4939 LZO compressions are not enabled by default, because they are,
4940 respectively, insecure and non-standardized. Note that TLS 1.2 will
4941 not be enabled by default in non-experimental release until it has
4942 been approved by the IETF.
4944 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4945 This means that to get DH_ANON and LZO compression, you'll need to
4946 specify that manually using '--kx anon' or '--comp lzo'.
4948 ** Minor fixes to the human display format of X.509 certificates.
4950 ** New APIs to extract Distinguished Name's from X.509 certificates.
4951 Based on patch from Howard Chu <hyc@symas.com>.
4953 ** Improved library searching for opencdk.
4954 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4955 The deprecated opencdk.m4 is no longer used.
4957 ** New APIs to list supported algorithms in the library.
4958 The APIs are gnutls_cipher_list, gnutls_mac_list,
4959 gnutls_compression_list, gnutls_protocol_list,
4960 gnutls_certificate_type_list, gnutls_kx_list, and
4961 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4963 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4965 ** New configure option --disable-tls-authorization to disable tls-authz.
4967 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4968 The last parameter was renamed from 'flags' to 'format' and the type
4969 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4970 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4973 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4974 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4976 ** API and ABI modifications:
4977 gnutls_x509_dn_t: ADD.
4978 gnutls_x509_ava_st: ADD.
4979 gnutls_x509_crt_get_subject,
4980 gnutls_x509_crt_get_issuer: ADD.
4981 gnutls_x509_dn_get_rdn_ava: ADD.
4982 gnutls_cipher_list: ADD.
4983 gnutls_mac_list: ADD.
4984 gnutls_compression_list: ADD.
4985 gnutls_protocol_list: ADD.
4986 gnutls_certificate_type_list: ADD.
4987 gnutls_kx_list: ADD.
4988 gnutls_cipher_suite_info: ADD.
4990 * Version 1.7.7 (released 2007-02-22)
4992 ** Support for supplemental handshake messages and authorization data.
4993 Supplemental data is described in RFC 4680 and the authorization
4994 extensions in draft-housley-tls-authz-extns-07.
4996 ** Support for authorization data in gnutls-cli and gnutls-serv.
4997 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4999 ** Fix for gnutls_x509_crt_check_hostname.
5000 Before it would have reported that the certificate matched a hostname
5001 when it did not have any dNSName or any CN field. Report and tiny
5002 patch from "Richard W.M. Jones" <rjones@redhat.com>.
5004 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
5005 Tests regressions of the bug, and several other features.
5007 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
5008 Before there were no support for iPAddress SAN's during comparison.
5010 ** New API to print information about CRL's.
5011 The function is gnutls_x509_crl_print.
5013 ** New API to extract signature value from CRL's.
5014 The function is gnutls_x509_crl_get_signature.
5016 ** Support for directoryName Subject Alternative Name's.
5017 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
5018 string in the provided buffer.
5020 ** Internal improvements to certtool.
5021 It uses gnutls_x509_crl_print to print CRL information. It uses some
5022 more gnulib modules to simplify error handling.
5024 ** API and ABI modifications:
5025 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
5026 gnutls_supplemental_data_format_type_t: ADD.
5027 gnutls_authz_data_format_type_t: ADD.
5028 gnutls_supplemental_get_name: ADD.
5029 gnutls_authz_recv_callback_func,
5030 gnutls_authz_send_callback_func: ADD, callback prototypes.
5031 gnutls_authz_enable: ADD.
5032 gnutls_authz_send_x509_attr_cert,
5033 gnutls_authz_send_saml_assertion,
5034 gnutls_authz_send_x509_attr_cert_url,
5035 gnutls_authz_send_saml_assertion_url: ADD.
5036 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
5037 gnutls_x509_crl_print: ADD.
5038 gnutls_x509_crl_get_signature: ADD.
5040 * Version 1.7.6 (released 2007-02-12)
5042 ** Support for 'otherName' Subject Alternative Names.
5043 The existing API gnutls_x509_crt_get_subject_alt_name may now return
5044 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
5045 To find out the otherName OID (necessary for proper parsing of the
5046 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
5047 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
5048 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
5049 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
5051 ** Certtool can print otherName SAN values for certificates.
5052 For known otherName OIDs (currently only id-on-xmppAddr as defined by
5053 RFC 3920), it will also print the name.
5055 ** Fix TLS 1.2 RSA signing in servers.
5056 Before it used the old-style MD5+SHA1 signature, but the TLS
5057 signatures should be normal PKCS#1 signatures. FYI, we use and
5058 require that DigestInfo parameters are present and NULL for TLS 1.2.
5060 ** Add APIs to access X.509 extensions sequentially.
5061 The existing APIs gnutls_x509_crt_get_extension_oid() and
5062 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
5063 inspect the extensions in the order defined by the certificate.
5065 ** Add API to extract signature value from X.509 certificates.
5066 The function is gnutls_x509_crt_get_signature.
5068 ** Fix crash when generating proxy certificates in batch mode.
5069 If you don't specify a proxy policy in batch mode, it will use
5072 ** Add API to print information about X.509 certificates.
5073 The function is gnutls_x509_crt_print.
5075 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
5076 One consequence of this is that the output syntax has changed
5077 slightly. Some more fields are printed.
5081 ** API and ABI modifications:
5082 gnutls_x509_crt_print: ADD
5083 gnutls_certificate_print_formats_t: ADD, new enum.
5084 gnutls_x509_crt_get_signature: ADD.
5085 gnutls_x509_crt_get_extension_data: ADD.
5086 gnutls_x509_crt_get_extension_info: ADD.
5087 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
5088 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
5089 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
5091 * Version 1.7.5 (released 2007-02-06)
5093 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
5096 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
5098 ** Fix --list output for gnutls-cli and gnutls-serv.
5099 Mention TLS1.2, SHA512 etc.
5101 ** Manual contains new section on setting up a test HTTP server.
5102 A server set up following those descriptions are available online via
5103 <http://www.gnutls.org/server.html>.
5105 ** Update of gnulib files.
5107 ** API and ABI modifications:
5108 No changes since last version.
5110 * Version 1.7.4 (released 2007-02-05)
5112 ** Support for RSA signing using SHA-256/384/512.
5113 A new self test "sha2" tries to build a long X.509 certificate chain
5114 testing all new hashes.
5116 ** The gnutls-serv tool now use static DH parameters if none are supplied.
5118 ** Discuss proxy certificates in the manual.
5120 ** Improve bibliographical citations in the manual.
5122 ** Update of gnulib files.
5124 ** Fix certtool template handling of pathLenConstraints.
5125 It now defaults to -1 instead of 0, which causes the field to be
5126 missing unless the template specify it.
5128 ** API and ABI modifications:
5131 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
5134 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
5135 GNUTLS_SIGN_RSA_SHA256,
5136 GNUTLS_SIGN_RSA_SHA384,
5137 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
5139 * Version 1.7.3 (released 2007-02-01)
5141 ** New option to certtool: --generate-proxy.
5142 This will generate a Proxy Certificate from an end entity certificate.
5143 Proxy Certificates are documented in RFC 3820. You will need to
5144 specify the proxy certificate's private key with --load-privkey, the
5145 user certificate with --load-certificate and the private key used to
5146 sign the new proxy certificate with --load-ca-privkey. Certtool will
5147 query for proxy path length and the policy language OID. Currently
5148 only OIDs that have an empty policy are supported (which includes the
5149 two OIDs defined by RFC 3820).
5151 ** Certtool --certificate-info now prints information for Proxy Certificates.
5152 Before the proxy extension was just printed as DER encoded data.
5154 ** New APIs to set proxy subject names and get/set proxy cert extension.
5156 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
5158 ** Added self-test to test for regressions of pathLenConstraint bug.
5159 Incidentally, this also test (some) other regressions or changes in
5160 the output from certtool --certificate-info.
5162 ** When certtool generates CA certificates, pressing enter on the path
5163 ** length constraint query will now remove the field.
5164 Before it set the path length constraint to 0, which is a rather poor
5167 ** Certtool now print times in UTC when printing certificate/CRL info.
5169 ** Add better fix to work around C++ compiler bug on Mac OS X.
5170 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
5172 ** Fix import of ASCII armored OpenPGP keys.
5173 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
5175 ** Update of gnulib files.
5177 ** API and ABI modifications:
5178 gnutls_x509_crt_set_proxy_dn: ADD.
5179 gnutls_x509_crt_set_proxy: ADD.
5180 gnutls_x509_crt_get_proxy: ADD.
5182 * Version 1.7.2 (released 2007-01-14)
5184 ** Certtool now print the value of the pathLenConstraints field for certs.
5186 ** Certtool now query for path length constraints when generating CA certs.
5187 For batch uses, the certtool configuration name is "path_len".
5188 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5190 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
5191 The new functions gnutls_x509_crt_get_basic_constraints and
5192 gnutls_x509_crt_set_basic_constraints provide a superset of the
5193 functionality in the old gnutls_x509_crt_get_ca_status and
5194 gnutls_x509_crt_set_ca_status (respectively), but the old functions
5195 will continue to be supported.
5197 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5198 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5199 OpenCDK release with this patch will be made soon, which should bump
5200 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5202 ** Certtool --to-p12 can now store more than one certificate in the blob.
5203 Before it could only store one certificate, but now it will read and
5204 store as many certificate there are from the --load-certificate file.
5205 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5207 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5208 In particular, the OpenPGP function variables are no longer part of
5209 the exported libgnutls interface, and no header files from
5210 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5211 were never intended for non-internal purposes, and thus this does not
5212 imply a change in the external API/ABI.
5214 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5215 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5217 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5218 Before these parameters were set to make GnuTLS build under mingw32,
5219 however, they appear to no longer be necessary.
5221 ** A minor fix to the C++ library to make it build.
5222 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5224 ** Update of gnulib files.
5226 ** API and ABI modifications:
5227 gnutls_x509_crt_get_basic_constraints: ADD.
5228 gnutls_x509_crt_set_basic_constraints: ADD.
5229 cdk_pubkey_to_sexp: ADD (in opencdk).
5230 cdk_seckey_to_sexp: ADD (in opencdk).
5232 * Version 1.7.1 (released 2006-12-28)
5234 ** TLS 1.2 server side fix.
5235 The Certificate Request sent did not contain the list of supported
5236 hashes field, thus violating the protocol. It will now contain an
5237 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5239 ** TLS 1.2 DSA signature verification fix.
5240 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5242 ** Fix the list of trusted CAs that server's send to clients.
5243 Before, the list contained issuer DN's instead of subject DN's of the
5244 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5246 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5247 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5248 function. Reported by Max Kellermann <max@duempel.org>.
5250 ** Encode UID fields in DN's as DirectoryString.
5251 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5252 incorrect, it should have used DirectoryString. Now it will use
5253 DirectoryString for the UID field, but for backwards compatibility it
5254 will also accept IA5String UID's. Reported by Max Kellermann
5257 ** Improve out-of-sourcedir builds from CVS.
5258 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5260 ** Bootstrap tools changed.
5261 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5262 building GnuTLS from CVS. Libtool 1.5.22 is used.
5264 ** Fixed a syntax error in lib/gnutls.asn.
5265 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5267 ** Added German translation of GnuTLS messages.
5269 ** Update of gnulib files.
5271 ** API and ABI modifications:
5272 No changes since last version.
5274 * Version 1.7.0 (released 2006-11-29)
5276 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5277 The details is that the protocol priority set by
5278 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5279 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5281 ** Preliminary support for TLS 1.2.
5282 The client has been successfully tested against
5283 https://www.mikestoolbox.org:4433/.
5285 ** Anonself test now print a lot of debugging info, including TLS version.
5287 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5289 ** Update of gnulib files.
5291 ** API and ABI modifications:
5292 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5294 *** Pulled up from stable 1.6.x branch:
5296 ** Fix ./configure failure with non-GCC compilers.
5297 This fixes the following error message:
5298 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5299 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5301 * Version 1.6.3 (released 2007-05-26)
5303 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5304 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5305 from the 1.7.x branch, see
5306 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5308 ** Have PKCS8 parser return better error codes.
5309 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
5310 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
5311 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5313 ** Fix mem leak for sessions with client authentication via certificates.
5314 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5315 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5317 ** Fix building of 'tlsia' self test.
5318 Earlier some gcc are known to build tlsia linking to
5319 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5320 the build directory, even though command line parameters look OK.
5321 Changing order of some parameters fixes it.
5323 ** API and ABI modifications:
5324 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5325 gnutls_x509_crt_get_raw_dn: ADD.
5327 * Version 1.6.2 (released 2007-04-18)
5329 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5330 Before, we remove the parameters field, which resulted in a slightly
5331 different DER encoding which in turn caused signature verification
5332 failures of GnuTLS-generated RSA certificates in some other
5333 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5334 you read, this may or may not be correct, but our new behaviour appear
5335 to be consistent with other widely used implementations.
5337 ** Regenerate the PKIX ASN.1 syntax tree.
5338 For some reason, after changing the ASN.1 type of ldap-UID in the last
5339 release, the generated C file built from the ASN.1 schema was not
5340 refreshed. This can cause problems when reading/writing UID
5341 components inside X.500 Distinguished Names. Reported by devel
5342 <dev001@pas-world.com>.
5344 ** Updated translations.
5346 ** API and ABI modifications:
5347 No changes since last version.
5349 * Version 1.6.1 (released 2006-12-28)
5351 ** Fix the list of trusted CAs that server's send to clients.
5352 Before, the list contained issuer DN's instead of subject DN's of the
5353 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5355 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5356 Reported by Max Kellermann <max@duempel.org>.
5358 ** Encode UID fields in DN's as DirectoryString.
5359 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5360 incorrect, it should have used DirectoryString. Now it will use
5361 DirectoryString for the UID field, but for backwards compatibility it
5362 will also accept IA5String UID's. Reported by Max Kellermann
5365 ** Fix ./configure failure with non-GCC compilers.
5366 This fixes the following error message:
5367 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5368 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5370 ** API and ABI modifications:
5371 No changes since last version.
5373 * Version 1.6.0 (released 2006-11-17)
5375 ** No changes since 1.5.5.
5376 The major changes compared to the 1.4.x branch are:
5378 *** A GnuTLS C++ library is part of the official distribution.
5379 Currently there are no examples or documentation, but hopefully this
5380 will change. See gnutlsxx.h for the API.
5382 *** Windows is a supported platform.
5383 There are, however, two know bugs. One is related to select() in
5384 command line tools (not, nota bene, in the library), the other is a
5385 problem with libgcrypt that causes delays. Help is needed to resolve
5386 those issues, so we feel we can't delay the release because of this.
5388 *** New APIs for custom push/pull function error reporting.
5389 The new APIs are gnutls_transport_set_errno and
5390 gnutls_transport_set_global_errno. See the release notes for version
5391 1.5.4 for more information.
5393 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5395 * Version 1.5.5 (released 2006-11-16)
5397 ** Correctly bump shared library version after adding new APIs.
5398 This was forgotten in the last release.
5400 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5401 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5403 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5405 ** Update of gnulib files.
5407 ** API and ABI modifications:
5408 No changes since last version.
5410 * Version 1.5.4 (released 2006-11-07)
5412 ** New API functions to set errno in push/pull functions.
5413 Under Windows, setting the errno variable in a push/pull replacement
5414 may end up setting the wrong errno variable, and GnuTLS send/recv
5415 functions become confused about the real errno returned from a failed
5416 push/pull function. Therefor, we have added two APIs to set the errno
5417 variable used by GnuTLS. The APIs can also help to keep things
5418 thread-safe, by avoiding potentially global variables. Typically,
5419 instead of setting errno in your push/pull function, you will call one
5420 of these functions. It is recommended to use
5421 gnutls_transport_set_errno, but if you don't have the session variable
5422 easily accessible in the push/pull replacement function, you can use
5423 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5424 <tim.kosse@filezilla-project.org>.
5426 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5427 void gnutls_transport_set_global_errno (int err);
5429 ** When calling `recv' or `send' Windows errors are handled properly.
5430 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5431 WSAGetLastError to access the error condition instead.
5433 ** Several OpenPGP API fixes.
5434 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5435 important fix is to change the return value of
5436 gnutls_openpgp_privkey_get_pk_algorithm and
5437 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5438 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5439 compatible with 'int').
5441 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5442 ** version, try to negotiate the highest version support by the GnuTLS server,
5443 ** instead of the lowest.
5444 Reported by <Pasi.Eronen@nokia.com>.
5446 ** Replace old constructs with use of gnulib modules.
5447 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5448 the code. If the headers doesn't exist on the target system, gnulib
5449 will make sure its replacement header files are used instead.
5451 ** Fix SOVERSION computation for *.def files.
5452 This fixes build errors similar to "No rule to make target
5453 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5455 ** gnutls_check-version uses strverscmp from gnulib.
5457 ** Update of gnulib files.
5459 ** API and ABI modifications:
5460 gnutls_transport_set_errno: ADD
5461 gnutls_transport_set_global_errno: ADD
5463 * Version 1.5.3 (released 2006-10-26)
5465 ** Add new self-test of RSA-MD5 signature chains.
5466 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5467 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5468 and is based on the work by Marc Stevens et al, see
5469 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5471 ** Re-factor self tests.
5473 ** The include copy of Libtasn1 is updated to version 0.3.7.
5475 ** The included copy of OpenCDK is updated to version 0.5.11.
5477 ** Fix the filename of the *.def file on Windows after library version bump.
5479 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5480 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5481 gnulib modules. Earlier we could only use the LGPL'ed module from
5482 gnulib, because two gnulib directories in the same project didn't
5485 ** API and ABI modifications:
5486 No changes since last version.
5488 * Version 1.5.2 (released 2006-10-03)
5490 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5491 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5492 shared library version than this version, so you'll have to remove
5493 them and possibly relink your applications. The reason for this is
5494 that no API/ABI changes have been made since the 1.4.x branch, and
5495 that incrementing the shared library version was a mistake. Reported
5496 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5498 ** Fix off-by-one error when computing length to malloc.
5499 The code is used by gnutls_openpgp_add_keyring_file and
5500 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5501 <agl@imperialviolet.org>.
5503 ** Add version script for the GnuTLS C++ library.
5504 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5506 ** Fix the C++ compiler detection logic.
5507 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5509 ** Update of gnulib files.
5511 ** API and ABI modifications:
5512 No changes since last version.
5514 * Version 1.5.1 (released 2006-09-21)
5516 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5517 ** Crypto 06 rump session attack.
5518 In particular, we check that the digestAlgorithm.parameters field is
5519 missing or empty, to avoid that it can contain "garbage" that may be
5520 used to alter the numeric properties of the signature. See
5521 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5522 not exactly the same as the problem we fix here). Reported by Yutaka
5523 OIWA <y.oiwa@aist.go.jp>.
5525 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5526 up to date information.
5528 ** Add self test to test for above flaw.
5530 ** Fix gnutls-cli-debug regarding resume support detection.
5531 Earlier, if the session-id from the server had a length of 0, it would
5532 indicate that the server supports resumption, which isn't the case.
5533 Reported by Kataja Kai <kai.kataja@op.fi>.
5535 ** Fix building of examples on FreeBSD by including netinet/in.h.
5536 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5538 ** Fix certtool bug that caused the private key to not be loaded when
5539 generating a certificate with --load-request, which in turn triggered
5540 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5541 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5543 ** gnutls-cli and gnutls-serv works on Windows.
5544 The problem was the select() call that doesn't work on file
5545 descriptors (stdin) on Windows. We borrowed some code from plibc to
5546 solve this. It appears to be somewhat unreliable though.
5548 ** Autoconf 2.60 is now used.
5550 ** API and ABI modifications:
5551 No changes since last version.
5553 * Version 1.5.0 (released 2006-08-13)
5555 ** Change SRP and Cert-Type extensions to match IANA registry.
5557 ** Fixed bug in OpenPGP authentication handshake.
5559 ** Improvements for building under MinGW.
5560 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5561 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5562 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5563 at run-time from ws2_32.dll, and falls back on a simple replacement if
5564 it is not available. Builds the library with -mms-bitfields
5565 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5566 create *.def files, which are installed.
5568 ** The examples now (conditionally) include config.h and link to gnulib.
5569 No other source changes were necessary, so the examples should
5570 continue to be possible to use stand-alone without any autoconf or
5573 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5574 You may unconditionally disable it with --disable-cxx. See
5575 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5578 ** Made command line tool '--version' behave according to GNU Standards.
5579 This enables 'make distcheck' to succeed.
5581 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5583 ** Make --without-included-libtasn1 work.
5584 Reported by Daniel Black <dragonheart@gentoo.org>.
5586 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5587 See http://www.gnu.org/software/gnutls/security.html regardging
5588 GNUTLS-SA-2006-2 for more up to date information. Reported by
5589 satyakumar <satyam_kkd@hyd.hellosoft.com>.
5591 ** API and ABI modifications:
5592 No changes since last version.
5594 * Version 1.4.5 (released 2006-11-06)
5596 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5597 ** version, try to negotiate the highest version support by the GnuTLS server,
5598 ** instead of the lowest.
5599 Reported by <Pasi.Eronen@nokia.com>.
5601 ** Fix typo in doc/examples/ex-serv-pgp.c.
5602 Reported by Adam Langley" <agl@imperialviolet.org>.
5604 ** API and ABI modifications:
5605 No changes since last version.
5607 * Version 1.4.4 (released 2006-09-12)
5609 ** Relax the test that caught signatures that exploit the variant of
5610 ** Bleichenbacher's Crypto 06 rump session attack on our
5611 ** verification logic flaw.
5612 In particular, we now permit the digestAlgorithm.parameters field to
5613 be present but empty, whereas in 1.4.3 we actually checked that the
5616 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5617 The messages are only printed in debug mode, which is not recommended
5618 for normal use, and thus logging this situation cannot be abused as an
5619 oracle in typical recommended situations.
5621 ** API and ABI modifications:
5622 No changes since last version.
5624 * Version 1.4.3 (released 2006-09-08)
5626 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5627 ** Crypto 06 rump session attack.
5628 In particular, we check that the digestAlgorithm.parameters field is
5629 empty, to avoid that it can contain "garbage" that may be used to
5630 alter the numeric properties of the signature. See
5631 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5632 not exactly the same as the problem we fix here). Reported by Yutaka

5645 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
5647 ** API and ABI modifications:
5648 No changes since last version.
5650 * Version 1.4.2 (released 2006-08-12)
5652 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5653 This can happen if you call gnutls_certificate_verify_peers2 and have
5654 a certain mix of local CA certificates and the peer send special
5655 certificates, that together trigger certain behaviour. It is not
5656 known at this point whether the crash can be triggered without the
5657 special local CA certificate, and thus turn this into a remote crash
5658 of clients that verify server certificates when they talk to a server
5659 with the special server certificate. See GNUTLS-SA-2006-2 on
5660 http://www.gnu.org/software/gnutls/security.html for more up to date
5661 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5663 ** Change SRP and Cert-Type extensions to match IANA registry.
5665 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5667 ** Make --without-included-libtasn1 work.
5668 Reported by Daniel Black <dragonheart@gentoo.org>.
5670 ** API and ABI modifications:
5671 No changes since last version.
5673 * Version 1.4.1 (released 2006-06-14)
5675 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5677 ** Fixed bug in OpenPGP authentication handshake.
5679 ** Fixed typographical in man pages.
5681 ** Build fixes of the manual.
5683 ** Added Swedish translation.
5685 ** API and ABI modifications:
5686 No changes since last version.
5688 * Version 1.4.0 (released 2006-05-15)
5690 ** Remove GnuTLS 0.8.x compatibility functions.
5692 ** The libgcrypt RNG is initialized in gnutls_global_init().
5694 ** TLS/IA API changes from Emile van Bergen.
5695 A dummy credential structure is not needed now, if you wish to use the
5696 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5699 ** The self-tests are now run under valgrind, if it is installed.
5701 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5703 ** The command line tools now use getaddrinfo and support IPv6.
5705 ** API and ABI modifications:
5706 _gnutls_x509_get_raw_crt_activation_time,
5707 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5708 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5709 gnutls_ia_enable: Added.
5711 * Version 1.3.5 (released 2006-03-08)
5713 ** Error messages are now translated using GNU Gettext.
5715 ** The function gnutls_x509_crt_to_xml now return an internal error.
5716 This means that the code to convert X.509 certificates to XML format
5717 does not work any more. The reason is that the function called
5718 libtasn1 internal functions. It seems unclean for libtasn1 to export
5719 the APIs needed here. Instead it would be better to implement XML
5720 support inside libtasn1 properly. If you need this functionality
5721 strongly, please consider looking into implementing this suggested
5722 approach instead. As a workaround, you may also modify lib/x509/xml.c
5723 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5725 ** Libraries are now built with libtool's -no-undefined.
5726 This helps producing libraries for Windows using mingw32.
5728 ** Doc fixes to explain that gnutls_record_send can block.
5730 ** Libtasn1 0.3.1 or later is now required.
5731 The include copy has been updated too.
5733 ** gnutls-cli can now recognize services and port numbers with the -p option.
5735 ** API and ABI modifications:
5736 No changes since last version.
5738 * Version 1.3.4 (released 2006-02-09)
5740 ** Fix read of out bounds bug in DER parser.
5741 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5742 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5743 previous bug fix. The included libtasn1 version in GnuTLS has been
5746 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5747 longer invalidate a session if the underlying send fails, but it will
5748 prevent future writes. That is to allow reading the already received data.
5749 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5751 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5752 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5753 more than one certificates were added. Report and patch by Max Kellermann.
5755 ** Fix build problems of OpenCDK on AIX.
5756 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5758 ** API and ABI modifications:
5759 No changes since last version.
5761 * Version 1.3.3 (released 2006-01-12)
5763 ** New API to access the TLS master secret.
5764 When possible, you should use the TLS PRF functions instead.
5765 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5767 ** Improved handling when multiple libraries use GnuTLS at the same time.
5768 Now gnutls_global_init() can be called multiple times, and
5769 gnutls_global_deinit() will only deallocate the structure when it has
5770 been called as many times as gnutls_global_init() was called.
5772 ** Added a self test of TLS resume functionality.
5774 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5776 ** Documentation fixes about thread unsafety, prompted by
5777 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5778 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5779 thread safe. Careful callers may want to protect the call using a
5780 mutex. The problem could also be ignored, which would cause a memory
5781 leak under rare conditions when two threads invoke the function
5782 roughly at the same time.
5784 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5786 ** The code was indented again, including the external header files.
5788 ** API and ABI modifications:
5789 New functions to retrieve the master secret value:
5790 gnutls_session_get_master_secret
5792 Add a 'const' keyword to existing API:
5793 gnutls_x509_crq_get_challenge_password
5795 * Version 1.3.2 (released 2005-12-15)
5797 ** GnuTLS now support TLS Inner application (TLS/IA).
5798 This is per draft-funk-tls-inner-application-extension-01. This
5799 functionality is added to libgnutls-extra, so it is licensed under the
5800 GNU General Public License.
5802 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5803 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5804 and EAP-TTLS. One function to access the raw PRF and one to access
5805 the PRF seeded with the client/server random fields are provided.
5806 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5808 ** New APIs to acceess the client and server random fields in a session.
5809 These fields can be useful by protocols using TLS. Note that these
5810 fields are typically used as input to the TLS PRF, and if this is your
5811 intended use, you should use the TLS PRF API that use the
5812 client/server random field directly. Suggested by Jouni Malinen
5813 <jkmaline@cc.hut.fi>.
5815 ** Internal type cleanups.
5816 The uint8, uint16, uint32 types have been replaced by uint8_t,
5817 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5818 correct types on platforms that lack them. The uint type have been
5819 replaced by unsigned.
5821 ** API and ABI modifications:
5822 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5826 New functions to retrieve the session's client and server random values:
5827 gnutls_session_get_server_random
5828 gnutls_session_get_client_random
5830 New function, to perform TLS/IA handshake:
5833 New function to decide whether to do a TLS/IA handshake:
5834 gnutls_ia_handshake_p
5836 New functions to allocate a TLS/IA credential:
5837 gnutls_ia_allocate_client_credentials
5838 gnutls_ia_free_client_credentials
5839 gnutls_ia_allocate_server_credentials
5840 gnutls_ia_free_server_credentials
5842 New functions to handle the AVP callback:
5843 gnutls_ia_set_client_avp_function
5844 gnutls_ia_set_client_avp_ptr
5845 gnutls_ia_get_client_avp_ptr
5846 gnutls_ia_set_server_avp_function
5847 gnutls_ia_set_server_avp_ptr
5848 gnutls_ia_get_server_avp_ptr
5850 New functions, to toggle TLS/IA application phases:
5851 gnutls_ia_require_inner_phase
5853 New function to mix session keys with inner secret:
5854 gnutls_ia_permute_inner_secret
5856 Low-level API (used internally by gnutls_ia_handshake):
5857 gnutls_ia_endphase_send
5861 New functions that can be used after successful TLS/IA negotiation:
5862 gnutls_ia_generate_challenge
5863 gnutls_ia_extract_inner_secret
5865 Enum type with TLS/IA modes:
5868 Enum type with TLS/IA packet types:
5871 Enum values for TLS/IA alerts:
5872 GNUTLS_A_INNER_APPLICATION_FAILURE
5873 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5875 New error codes, to signal when an application phase has finished:
5876 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5877 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5879 New error code to signal TLS/IA verify failure:
5880 GNUTLS_E_IA_VERIFY_FAILED
5882 * Version 1.3.1 (released 2005-12-08)
5884 ** Support for DHE-PSK cipher suites has been added.
5885 This method offers perfect forward secrecy.
5887 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5888 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5890 ** Corrected a bug in certtool for 64 bit machines. Reported
5891 by Max Kellermann <max@duempel.org>.
5893 ** New function to set a X.509 private key and certificate pairs, and/or
5894 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5895 <emile@e-advies.nl>.
5897 The integrity of the PKCS#12 file is protected through a password
5898 based MAC; public-key based signatures for integrity protection are
5899 not supported. PKCS#12 bags may be encrypted using password derived
5900 symmetric keys, public-key based encryption is not supported. The
5901 PKCS#8 keys may be encrypted using passwords. The API use the same
5902 password for all operations. We believe that any more flexibility
5903 create too much complexity that would hurt overall security, but may
5904 add more PKCS#12 related APIs if real-world experience indicate
5907 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5908 reported by Emile van Bergen <emile@e-advies.nl>.
5909 This will enable "certtool -k -8" to parse those keys.
5911 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5912 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5913 certtool would have encrypted the key using an empty password.
5915 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5916 Earlier it would have prompted the user for it, even if --password was
5919 ** Added self test of PKCS#8 parsing.
5920 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5921 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5924 ** API and ABI modifications:
5925 New function to set X.509 credentials from a PKCS#12 file:
5926 gnutls_certificate_set_x509_simple_pkcs12_file
5928 New gnutls_kx_algorithm_t enum type:
5931 New API to return session data (basically same as gnutls_session_get_data):
5932 gnutls_session_get_data2
5934 New API to set PSK Diffie-Hellman parameters:
5935 gnutls_psk_set_server_dh_params
5937 * Version 1.3.0 (2005-11-15)
5939 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5940 This add several new APIs, see below. Read the updated manual for
5941 more information. A new self test "pskself" has been added, that will
5942 test this functionality.
5944 ** The session resumption data are now system independent.
5946 ** The code has been re-indented to conform to the GNU coding style.
5948 ** Removed the RIPEMD ciphersuites.
5950 ** Added a discussion of the internals of gnutls in manual.
5952 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5954 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5956 ** Make sure config.h is included first in a few files, from Albert Chin.
5958 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
5960 ** Don't install SRP programs and man pages if --disable-srp-authentication,
5963 ** API and ABI modifications:
5964 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
5966 New gnutls_credentials_type_t credential type:
5969 New credential types:
5970 gnutls_psk_server_credentials_t
5971 gnutls_psk_client_credentials_t
5973 New functions to allocate PSK credentials:
5974 gnutls_psk_allocate_client_credentials
5975 gnutls_psk_free_client_credentials
5976 gnutls_psk_free_server_credentials
5977 gnutls_psk_allocate_server_credentials
5979 New enum type for PSK key flags:
5980 gnutls_psk_key_flags
5982 New function prototypes for credential callback:
5983 gnutls_psk_client_credentials_function
5984 gnutls_psk_server_credentials_function
5986 New function to set PSK username and key:
5987 gnutls_psk_set_client_credentials
5989 New function to set PSK passwd file:
5990 gnutls_psk_set_server_credentials_file
5992 New function to extract PSK user in server:
5993 gnutls_psk_server_get_username
5995 New functions to set PSK callback:
5996 gnutls_psk_set_server_credentials_function
5997 gnutls_psk_set_client_credentials_function
5999 Use size_t instead of int for output size parameter:
6000 gnutls_srp_base64_encode
6001 gnutls_srp_base64_decode
6003 * Version 1.2.11 (2006-05-11)
6004 - The function gnutls_x509_crt_to_xml is not supported any more, and
6005 return an internal error. The reason is that the function called
6006 internal libtasn1 functions which are no longer exported from
6008 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
6009 - Updated gnulib compatibility files.
6010 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
6011 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
6012 - API and ABI modifications:
6013 No changes since last version.
6015 * Version 1.2.10 (2006-02-09)
6016 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
6017 <admin@gleg.net>, and debugging help from Protover SSL.
6018 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
6019 The included version has been updated too.
6020 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
6021 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
6022 - Corrected a bug in certtool for 64 bit machines. Reported
6023 by Max Kellermann <max@duempel.org>.
6024 - Corrected bugs in gnutls_certificate_set_x509_crl() and
6025 gnutls_certificate_set_x509_trust(), that caused memory corruption if
6026 more than one certificates were added. Report and patch by Max Kellermann.
6027 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
6028 longer invalidate a session if the underlying send fails, but it will
6029 prevent future writes. That is to allow reading the already received data.
6030 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
6032 * Version 1.2.9 (2005-11-07)
6033 - Documentation was updated and improved.
6034 - RSA-MD2 is now supported for verifying digital signatures.
6035 - Due to cryptographic advances, verifying untrusted X.509
6036 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
6037 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
6038 applications that must remain interoperable, you can use the
6039 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
6040 flags when verifying certificates. Naturally, this is not
6041 recommended default behaviour for applications. To enable the
6042 broken algorithms, call gnutls_certificate_set_verify_flags with the
6043 proper flag, to change the verification mode used by
6044 gnutls_certificate_verify_peers2.
6045 - Make it possible to send empty data through gnutls_record_send,
6046 to align with the send(2) API.
6047 - Some changes in the certificate receiving part of handshake to prevent
6048 some possible errors with non-blocking servers.
6049 - Added numeric version symbols to permit simple CPP-based feature
6050 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
6051 - The (experimental) low-level crypto alternative to libgcrypt used
6052 earlier (Nettle) has been replaced with crypto code from gnulib.
6053 This leads to easier re-use of these components in other projects,
6054 leading to more review and simpler maintenance. The new configure
6055 parameter --with-builtin-crypto replace the old --with-nettle, and
6056 must be used if you wish to enable this functionality. See README
6057 under "Experimental" for more information. Internally, GnuTLS has
6058 been updated to use the new "Generic Crypto" API in gl/gc.h. The
6059 API is similar to the old crypto/gc.h, because the gnulib code were
6060 based on GnuTLS's gc.h.
6061 - Fix compiler warning in the "anonself" self test.
6062 - API and ABI modifications:
6063 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
6064 This doesn't reflect a change in behaviour,
6065 so we don't break backwards compatibility.
6066 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
6067 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
6068 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
6069 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
6071 gnutls_x509_crt_list_verify,
6072 gnutls_x509_crt_verify, or
6073 gnutls_certificate_set_verify_flags.
6074 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
6075 used when broken signature algorithms
6076 is used (currently RSA-MD2/MD5).
6077 LIBGNUTLS_VERSION_MAJOR,
6078 LIBGNUTLS_VERSION_MINOR,
6079 LIBGNUTLS_VERSION_PATCH,
6080 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
6081 version number, can be used for feature existence
6084 * Version 1.2.8 (2005-10-07)
6085 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
6086 - Don't install the auxilliary libexamples library used by the
6087 examples in doc/examples/ on "make install", report and tiny patch
6088 from Thomas Klausner <tk@giga.or.at>.
6089 - If you pass a X.509 CA or PGP trust database to the command line
6090 tool, it will now abort the connection if the server certificate
6091 validation fails. Use the parameter --insecure to continue even
6092 after certificate validation failures. Inspired from discussion
6093 with Alexander Kotelnikov <sacha@myxomop.com>.
6094 - The test for socklen_t has been moved to gnulib.
6095 - Link failures for duplicate or missing "program_name" symbol has been fixed,
6096 patch from Martin Lambers <marlam@marlam.de>.
6097 - The command line tool and the examples no longer uses mmap or bzero,
6098 to make them more portable, patch from Martin Lambers
6100 - Made the PKCS #12 API handle null passwords. Based on patch by
6101 Anton Altaparmakov <aia21@cam.ac.uk>.
6102 - The GTK-DOC manual should build with current released tools.
6103 (But a copy of the output is included, so the tools are not required.)
6104 - The inet_ntop function is now used through gnulib.
6105 - API and ABI modifications:
6106 No changes since last version.
6108 * Version 1.2.7 (2005-09-09)
6109 - The GnuTLS and GnuTLS-extra libraries are now built with versioned symbols.
6110 - Certtool now complains when reading out-of-range X.509 serial
6111 numbers, suggested by Fran <e_agf@yahoo.es>.
6112 - Certtool now uses the readline library (when available) when reading
6113 X.509 serial numbers.
6114 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
6115 - Fixed compile warning regarding socklen_t on Mingw32, reported by
6116 Martin Lambers <marlam@marlam.de>.
6117 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
6118 - Gnulib is now used for the core library, enabling future code cleanups.
6119 - The gnutls-cli tool now use gnutls_certificate_verify_peers2,
6120 suggested by Daniel Stenberg <daniel@haxx.se>.
6121 - Doc fixes for gnutls_transport_set_push and gnutls_transport_set_pull.
6122 - Minilibtasn1 is now 0.2.17 (removed optional use of C99 macros).
6123 - Disable zlib support if zlib.h is not present.
6124 - A number of internal cleanups.
6125 - API and ABI modifications:
6126 No changes since last version.
6128 * Version 1.2.6 (2005-07-16)
6129 - MiniLZO updated to version 2.01 and moved to separate directory.
6130 - Collision between system LZO header files and MiniLZO header file
6131 fixed, reported by Matthias Urlichs <smurf@smurf.noris.de>.
6132 - Will now test for liblzo functionality in liblzo2 too, reported by
6133 Thomas Klausner <tk@giga.or.at>.
6134 - Minilibtasn1 is now 0.2.14 (no code changes).
6135 - Some code changes to avoid GTK-DOC warnings.
6136 - API and ABI modifications:
6137 No changes since last version.
6139 * Version 1.2.5 (2005-07-03)
