124 under the gnutls_ocsp namespace. Currently the functionality provided
125 is to parse and extract information from OCSP requests/responses, to
126 generate OCSP requests and to verify OCSP responses. See the manual
127 for more information. Run ./configure with --disable-ocsp to build
128 GnuTLS without OCSP support.

617 That might be useful to block DoS or other attacker from specific IPs.
619 ** libgnutls: gnutls_pkcs11_privkey_import_url() will now correctly read
620 the public key algorithm of the key.
622 ** libgnutls: Added gnutls_certificate_get_issuer() and
623 gnutls_x509_trust_list_get_issuer() to compensate for the
624 missing gnutls_certificate_get_x509_cas().
626 ** libgnutls: Added gnutls_x509_crq_verify() to allow
627 verification of the self signature in a certificate request.
628 This allows verifying whether the owner of the private key
629 is the generator of the request.
631 ** libgnutls: gnutls_x509_crt_set_crq() implicitly verifies
632 the self signature of the request.
634 ** API and ABI modifications:
635 gnutls_certificate_get_issuer: ADDED
636 gnutls_x509_trust_list_get_issuer: ADDED

643 gnutls_global_set_time_function: ADDED
645 GNUTLS_E_ECC_NO_SUPPORTED_CURVES: New error code
646 GNUTLS_E_ECC_UNSUPPORTED_CURVE: New error code
647 GNUTLS_KX_ECDHE_RSA: New key exchange method
648 GNUTLS_KX_ECDHE_ECDSA: New key exchange method

663 * Version 2.99.1 (released 2011-04-23)
665 ** libgnutls: LZO support was removed.
667 ** libgnutls: Corrections in SSLv2 client hello parsing.
669 ** libgnutls: Added support for AES-NI if detected. Uses
670 Andy Polyakov's AES-NI code.
672 ** libgnutls: Restored HMAC-MD5 for compatibility. Although considered
673 weak, several sites require it for connection. It is enabled for
674 "NORMAL" and "PERFORMANCE" priority strings.
676 ** libgnutls: depend on libdl.
678 ** libgnutls-extra: Dropped support of LZO compression via liblzo.
680 ** libgnutls: gnutls_transport_set_global_errno() was removed. This
681 function required GnuTLS to access system specific data, for no reason.
682 Use gnutls_transport_set_errno(), or your system's errno fascility
685 ** libgnutls: Added gnutls_certificate_set_retrieve_function2()
686 to set a callback to retrieve a certificate. The certificate is
687 received in a format that requires no processing from gnutls thus
688 it is suitable when performance is required.
690 ** API and ABI modifications:
691 gnutls_transport_set_global_errno: REMOVED
692 gnutls_certificate_set_retrieve_function2: ADDED
694 * Version 2.99.0 (released 2011-04-09)
696 ** libgnutls: Added Datagram TLS support.
698 ** libgnutls: Uses a single configure file and a single
699 gnulib library to save space.
701 ** libgnutls: Several bug fixes.
703 ** libgnutls: gnutls_transport_set_lowat() is no more.
705 ** libgnutls-openssl: modified to use modern gnutls' functions.
706 This introduces an ABI incompatibility with previous versions.
708 ** libgnutls: Corrected signature generation and verification
709 in the Certificate Verify message when in TLS 1.2. Reported
712 ** libgnutlsxx: The C++ interface returns exception on
713 every error and not only on fatal ones. This allows easier
716 ** libgnutls: Corrected issue in DHE-PSK ciphersuites that ignored
719 ** libgnutls: SRP and PSK are no longer set on the default priorities.
720 They have to be explicitly set.
722 ** libgnutls: During handshake message verification using DSS
723 use the hash algorithm required by it.
725 ** libgnutls: gnutls_recv() return GNUTLS_E_PREMATURE_TERMINATION
726 on unexpected EOF, instead of GNUTLS_E_UNEXPECTED_PACKET_LENGTH.
728 ** libgnutls: Added GCM mode (interoperates with tls.secg.org)
730 ** libgnutls-extra: Inner application extension was removed.
731 It was never standardized nor published as an RFC.
733 ** libgnutls: Added new certificate verification functions, that
734 can provide more details and are more efficient. Check
735 gnutls_x509_trust_list_*.
737 ** certtool: Uses the new certificate verification functions for
740 ** certtool: Added new certificate verification functionality
741 using the --verify option. Combined with --load-ca-certificate
742 it can verify a certificate chain against a list of certificates.
744 ** Several files unnecessarily included <gcrypt.h>; this has been fixed.
746 ** API and ABI modifications:
747 gnutls_dtls_set_timeouts: ADDED

822 ** API and ABI modifications:
823 No changes since last version.
828 * Version 2.12.0 (released 2011-03-24)
830 ** certtool: Warns on generation of DSA keys of over 1024 bits, about
831 the incompatibility with TLS other than 1.2.
833 ** libgnutls: Modified signature algorithm selection in client
834 certificate request, to avoid failures in DSA certificates.
836 ** libgnutls: Instead of failing with internal error, return
837 GNUTLS_E_INCOMPAT_DSA_KEY_WITH_TLS_PROTOCOL if an incompatible DSA
838 key with the negotiated protocol is encountered.
840 ** libgnutls: Bug fixes in the RSA ciphersuite behavior with openpgp keys.
842 ** libgnutls: Force state update when fork is detected in the nettle
845 ** libgnutls: modified gnutls_pubkey_import_openpgp() to use the preferred
846 subkey instead of setting explicitly one.
848 ** libgnutls: Corrected default behavior in record version of Client Hellos.
850 ** libgnutls-openssl: modified to use modern gnutls' functions.
851 This introduces an ABI incompatibility with previous versions.
853 ** API and ABI modifications:
854 gnutls_pubkey_import_openpgp: MODIFIED
859 ** libgnutls: The deprecated gnutls_x509_privkey_sign_hash() was
860 replaced by gnutls_privkey_sign_hash2().
862 ** libgnutls: gnutls_pubkey_verify_data, gnutls_pubkey_verify_hash,
863 gnutls_x509_privkey_verify_data, gnutls_x509_crt_verify_data,
864 gnutls_x509_crt_verify_hash return the negative error code
865 GNUTLS_E_PK_SIG_VERIFY_FAILED if verification fails to simplify error
868 ** libgnutls: Added helper functions for signature verification:
869 gnutls_pubkey_verify_data() and gnutls_pubkey_import_privkey().
871 ** libgnutls: Modified gnutls_privkey_sign_data().
873 ** gnutls_x509_crl_privkey_sign2(), gnutls_x509_crq_sign2()
874 gnutls_x509_privkey_sign_hash(), gnutls_x509_privkey_sign_data(),
875 gnutls_x509_crt_verify_hash(), gnutls_x509_crt_verify_data(), were
876 deprecated for gnutls_x509_crl_privkey_sign(),
877 gnutls_x509_crq_privkey_sign(), gnutls_privkey_sign_hash(),
878 gnutls_privkey_sign_data(), gnutls_pubkey_verify_hash()
879 gnutls_pubkey_verify_data() respectively.
881 ** libgnutls: gnutls_*_export_raw() functions now add leading zero in
884 ** libgnutls: Added convenience functions gnutls_x509_crl_list_import2()
885 and gnutls_x509_crt_list_import2().
887 ** crypto.h: Fix use with C++.
888 Reported by "Brendan Doherty" <brendand@gentrack.com>.
890 ** API and ABI modifications:
891 gnutls_x509_crl_list_import: ADDED

917 * Version 2.11.6 (released 2010-12-06)
919 ** libgnutls: Record version of Client Hellos is now set by default to
920 SSL 3.0. To restore the previous default behavior use %LATEST_RECORD_VERSION
923 ** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
924 This makes us comply with RFC3279. Reported by Michael Rommel.
926 ** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.
928 ** API and ABI modifications:
929 No changes since last version.
931 * Version 2.11.5 (released 2010-12-01)
933 ** libgnutls: Reverted default behavior for verification and
934 introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
935 V1 trusted CAs are allowed, unless the new flag is specified.
937 ** libgnutls: Correctly add leading zero to PKCS #8 encoded DSA key.
938 Reported by Jeffrey Walton.
940 ** libgnutls: Added SIGN-ALL, CTYPE-ALL, COMP-ALL, and VERS-TLS-ALL
941 as priority strings. Those allow to set all the supported algorithms
944 ** p11tool: Introduced. It allows manipulating pkcs 11 tokens.
946 ** gnutls-cli: Print channel binding only in verbose mode.
947 Before it printed it after the 'Compression:' output, thus breaking
948 Emacs starttls.el string searches.
950 ** API and ABI modifications:
951 gnutls_pkcs11_token_init: New function
952 gnutls_pkcs11_token_set_pin: New function
954 * Version 2.11.4 (released 2010-10-15)
956 ** libgnutls: Add new API gnutls_session_channel_binding.
957 The function is used to get the channel binding data. Currently only
958 the "tls-unique" (RFC 5929) channel binding type is supported, through
959 the GNUTLS_CB_TLS_UNIQUE type. See new section "Channel Bindings" in
962 ** gnutls-cli, gnutls-serv: Print 'tls-unique' Channel Bindings.
964 ** doc: Added pkcs11.h header file to GTK-DOC manual.
966 ** build: Update gnulib files.
968 ** i18n: Update translations.
970 ** tests: Add self tests gendh.c. Speed up Guile self checks.
972 ** API and ABI modifications:
973 gnutls_session_channel_binding: New function.
974 gnutls_channel_binding_t: New enumeration.
975 GNUTLS_CB_TLS_UNIQUE: New gnutls_channel_binding_t enum member.
976 GNUTLS_E_CHANNEL_BINDING_NOT_AVAILABLE: New error code.
978 * Version 2.11.3 (released 2010-10-14)
980 ** Indent code to follow the GNU Coding Standard.
981 You should be able to unpack the 2.11.2 release and run 'make indent'
982 twice to get exactly the same content as 2.11.3 except for generated
983 files. Using GNU Indent 2.2.11.
985 ** API and ABI modifications:
986 No changes since last version.
988 * Version 2.11.2 (released 2010-10-08)
990 ** libgnutls: Several bug fixes on session resumption
991 and session tickets support.
993 ** libgnutls: Add new extended key usage ipsecIKE.
995 ** certtool: Renamed PKCS #11 options to: --p11-provider,
996 --p11-export-url, --p11-list-certs, --p11-list-certs,
997 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
998 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
999 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1002 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1003 introduced with the new nettle code.
1005 ** libgnutls: Corrected advertizing issue for session tickets.
1007 ** API and ABI modifications:
1008 gnutls_x509_crt_get_subject_unique_id: ADDED.
1009 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1011 * Version 2.11.1 (released 2010-09-14)
1013 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1014 to use the libgcrypt back end.
1016 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1017 backend crypto library.
1019 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1021 ** libgnutls: Several updates in the buffering internal interface.
1023 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1024 tabs are being skipped.
1026 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1028 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1031 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1032 system calls. Applications that depended on it being 1 should explicitly call
1033 gnutls_transport_set_lowat().
1035 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1036 to ECRYPT II recommendations. Mappings were moved to a single location
1037 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1038 and 3072 keys only).
1040 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1041 gnutls_x509_privkey_import_pkcs8() without a password, if it
1042 is unable to decode the key.
1044 ** libgnutls: HMAC-MD5 no longer used by default.
1046 ** API and ABI modifications:
1047 gnutls_openpgp_privkey_sec_param: ADDED
1048 gnutls_x509_privkey_sec_param: ADDED
1050 * Version 2.11.0 (released 2010-07-22)
1052 ** libgnutls: support scattered write using writev(). This takes
1053 advantage of the new buffering layer and allows queuing of packets
1054 and flushing them. This is currently used for handshake messages
1057 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1058 alternative locking procedures. By default the system available
1059 locking is used. In *NIX pthreads are used and in windows the
1060 critical section API. This follows a different approach than the
1061 previous versions that depended on libgcrypt initialization. The
1062 locks are now set by default in systems that support it. Programs
1063 that used gcry_control() to set thread locks should insert it into
1065 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1069 ** libgnutls: Added support for reading DN from EV-certificates.
1071 jurisdictionOfIncorporationLocalityName,
1072 jurisdictionOfIncorporationStateOrProvinceName,
1073 jurisdictionOfIncorporationCountryName
1075 ** libgnutls: Added support for DSA signing/verifying with bit
1078 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1079 has to be called to register any required md5 handlers.
1081 ** libgnutls: Internal buffering code was replaced by simpler
1082 code contributed by Jonathan Bastien-Filiatrault.
1084 ** libgnutls: Internal API for extensions augmented to allow
1085 safe storing and loading of data on resumption. This allows writing
1086 self-contained extensions (when possible). As a side effect
1087 the OPRFI extension was removed.
1089 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1091 ** libgnutls: Added PKCS #11 support and an API to access objects in
1092 gnutls/pkcs11.h. Currently certificates and public keys can be
1093 imported from tokens, and operations can be performed on private keys.
1095 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1097 ** libgnutls: Added initial support for the nettle library. It uses
1098 the system's random generator for seeding. That is /dev/urandom in Linux,
1099 system calls in Win32 and EGD on other systems.
1101 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1102 works even when resuming a session.
1104 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1105 similar gnutls_certificate_set_server_retrieve_function() and
1106 gnutls_certificate_set_client_retrieve_function(). In addition it support
1107 PKCS #11 private keys.
1109 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1110 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1112 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1113 sizes for private keys using a human understandable scale.
1115 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1116 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1117 --pkcs11-delete-url, --pkcs11-write
1119 certtool: The --pkcs-cipher is taken into account when generating a
1120 private key. The default cipher used now is aes-128. The old behavior can
1121 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1123 certtool: Added --certificate-pubkey to print the public key of the
1126 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1127 can now accept a PKCS #11 URL in addition to a file. This will allow for
1128 example to use the Gnome-keyring trusted certificate list to verify

1211 * Version 2.10.1 (released 2010-07-25)
1213 ** libgnutls: Added support for broken certificates that indicate RSA
1216 ** gnutls-cli: Allow verification using V1 CAs.
1218 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1219 gnutls_x509_privkey_import_pkcs8() without a password, if it
1220 is unable to decode the key.
1222 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1223 a memory leak. Reported by Mads Kiilerich.
1225 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1226 issue a warning, that the output key might not be working everywhere.
1228 ** certtool: The --pkcs-cipher is taken into account when generating a
1229 private key. The default cipher used now is aes-128. The old behavior
1230 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1232 ** API and ABI modifications:
1233 No changes since last version.
1235 * Version 2.10.0 (released 2010-06-25)
1237 ** API and ABI modifications:
1238 No changes since last version.
1240 * Version 2.9.12 (released 2010-06-17)
1242 ** gnutls-cli: Make --starttls work again.
1243 Problem introduced in patch to use read() instead of fgets() committed
1246 ** API and ABI modifications:
1247 No changes since last version.
1249 * Version 2.9.11 (released 2010-06-07)
1251 ** libgnutls: Removed two APIs related to safe renegotiation.
1252 Use priority strings instead. The APIs were
1253 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1254 (Remember that we don't promise ABI stability during development
1255 series, so this doesn't cause an shared library ABI increment.)
1257 ** tests: More self testing of safe renegotiation extension.
1258 See tests/safe-renegotiation/README for more information.
1260 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1262 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1264 ** API and ABI modifications:
1265 gnutls_safe_negotiation_set_initial: REMOVED.
1266 gnutls_safe_renegotiation_set: REMOVED.
1268 * Version 2.9.10 (released 2010-04-22)
1270 ** libgnutls: Time verification extended to trusted certificate list.
1271 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1274 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1275 Based on patch by Pavan Konjarla. Adds new constant
1276 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1278 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1279 Solves the issue discussed in:
1280 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1281 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1282 Note that to allow connecting to unpatched servers the full protection
1283 is only enabled if the priority string %SAFE_RENEGOTIATION is
1284 specified. You can check whether protection is in place by querying
1285 gnutls_safe_renegotiation_status(). New error codes
1286 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1287 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1289 ** libgnutls: When checking openpgp self signature also check the signatures
1291 Ilari Liusvaara noticed and reported the issue and provided test
1294 ** libgnutls: Added cryptodev support (/dev/crypto).
1295 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1296 benchmark utility for AES. Adds new error codes
1297 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1299 ** libgnutls: Exported API to access encryption and hash algorithms.
1300 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1301 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1302 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1303 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1304 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1305 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1306 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1308 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1309 verification of certificate upon receipt rather than waiting until the
1310 end of the handshake.
1312 ** libgnutls: Don't send alerts during handshake.
1313 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1315 ** certtool: Corrected two issues that affected certificate request generation.
1316 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1317 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1318 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1319 those parameters there since other implementations don't do either and having
1320 them does not seem to offer anything (anyway you need the signer's certificate
1321 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1322 This however has the side-effect that public key IDs shown by certtool are
1323 now different than previous gnutls releases.
1324 (3) the option --pgp-certificate-info will verify self signatures
1326 ** certtool: Allow exporting of Certificate requests on DER format.
1328 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1330 ** gnutls-cli: Handle reading binary data from server.

1397 ** libgnutls: Fix for memory leaks on interrupted handshake.
1398 Reported by Tang Tong.
1400 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1401 ** extension and certificate verify field.
1402 This requires changes for TLS 1.2 servers and clients that use
1403 callbacks for certificate retrieval. They are now required to check
1404 with gnutls_sign_algorithm_get_requested() whether the certificate
1405 they send complies with the peer's preferences in signature
1408 ** libgnutls: In server side when resuming a session do not overwrite the
1409 ** initial session data with the resumed session data.
1411 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
1413 This affects also PKCS #12 encoded files. This adds the following new
1414 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
1415 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
1417 ** libgnutls: Fix PKCS#12 encoding.
1418 The error you would get was "The OID is not supported.". Problem
1419 introduced for the v2.8.x branch in 2.7.6.
1421 ** certtool: Added the --pkcs-cipher option.
1422 To explicitely specify the encryption algorithm to use.
1424 ** tests: Added "pkcs12_encode" self-test to check PKCS#12 functions.
1426 ** tests: Fix time bomb in chainverify self-test.
1427 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in

1465 * Version 2.9.5 (released 2009-09-10)
1467 ** libgnutls: Add new functions to extract X.509 Issuer Alternative Names.
1468 The new functions are gnutls_x509_crt_get_issuer_alt_name2,
1469 gnutls_x509_crt_get_issuer_alt_name, and
1470 gnutls_x509_crt_get_issuer_alt_othername_oid. Contributed by Brad

1482 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1483 SHA-256 is now the preferred default MAC (however it is only used with
1486 ** libgnutls: Make OpenPGP hostname checking work again.
1487 The patch to resolve the X.509 CN/SAN issue accidentally broken
1488 OpenPGP hostname comparison.
1490 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1491 Reported by Howard Chu <hyc@symas.com> in
1492 <https://savannah.gnu.org/support/?106975>.
1494 ** Fix use of deprecated types internally.
1495 Use of deprecated types in GnuTLS from now on will lead to a compile
1496 error, to prevent this from happening again.
1498 ** API and ABI modifications:
1499 No changes since last version.
1501 * Version 2.9.3 (released 2009-08-19)
1503 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1504 The new APIs are gnutls_session_ticket_enable_client,
1505 gnutls_session_ticket_enable_server, and
1506 gnutls_session_ticket_key_generate.
1508 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

1513 gnutls_session_ticket_enable_server: ADDED.
1515 * Version 2.9.2 (released 2009-08-14)
1517 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1518 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1519 into 1) not printing the entire CN/SAN field value when printing a
1520 certificate and 2) cause incorrect positive matches when matching a
1521 hostname against a certificate. Some CAs apparently have poor
1522 checking of CN/SAN values and issue these (arguable invalid)
1523 certificates. Combined, this can be used by attackers to become a
1524 MITM on server-authenticated TLS sessions. The problem is mitigated
1525 since attackers needs to get one certificate per site they want to
1526 attack, and the attacker reveals his tracks by applying for a
1527 certificate at the CA. It does not apply to client authenticated TLS
1528 sessions. Research presented independently by Dan Kaminsky and Moxie
1529 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1530 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1532 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1533 The function may fail incorrectly when an earlier certificate was
1534 imported to the same gnutls_x509_crt_t structure.
1536 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1538 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1539 Before it always returned false. Reported by Peter Hendrickson
1540 <pdh@wiredyne.com> in
1541 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
1543 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
1544 The error resulted in truncated strings when printing unknown OIDs in
1545 X.509 certificate DNs. Reported by Tim Kosse
1546 <tim.kosse@filezilla-project.org> in
1547 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
1549 ** libgnutls: Fix PKCS#12 decryption from password.
1550 The encryption key derived from the password was incorrect for (on
1551 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1552 Tomas" <tomas.kukosa@siemens-enterprise.com> in
1553 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.
1555 ** libgnutls: Return correct bit lengths of some MPIs.
1556 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1557 gnutls_dh_get_peers_public_bits. Before the reported value was
1558 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
1559 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
1561 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.
1562 Report and patch by Tim Kosse <tim.kosse@filezilla-project.org> in
1563 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3671>
1565 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
1567 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1568 Before we required that the runtime library used the same (or more
1569 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1570 that the runtime usage is above the minimum required. Reported by
1571 Marco d'Itri <md@linux.it> via Andreas Metzler
1572 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
1574 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
1576 ** tests: Improved test vectors in self-test pkcs12_s2k.
1578 ** tests: Added new self-test dn2 to detect off-by-one size error.
1580 ** tests: Fix failure in "chainverify" because a certificate have expired.
1582 ** API and ABI modifications:
1583 No changes since last version.
1585 * Version 2.9.1 (released 2009-06-08)
1587 ** libgnutls: Fix crash in gnutls_global_init after earlier init/deinit cycle.
1588 Forwarded by Martin von Gagern <Martin.vGagern@gmx.net> from
1589 <http://bugs.gentoo.org/272388>.
1591 ** tests: Added new self-tests init_roundtrip.c to detect previous problem.
1593 ** Reduce stack usage for some CRQ functions.
1595 ** Doc fixes for CRQ functions.
1597 ** API and ABI modifications:
1598 No changes since last version.
1600 * Version 2.9.0 (released 2009-05-28)
1604 ** API and ABI modifications:
1605 No changes since last version.
1607 * Version 2.8.6 (released 2010-03-15)
1609 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
1610 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1611 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1613 Note: As a side effect of this change, the "public key identifier"
1614 value computed for a certificate using this version of GnuTLS will be
1615 different from values computed using earlier versions of GnuTLS.
1617 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1618 ** optional SignatureAlgorithm parameter field.
1619 VeriSign rejected these CSRs. They are stricly speaking not needed
1620 since you need the signer's certificate to verify the certificate
1621 signature anyway. Reported by Wilankar Trupti
1622 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1624 ** libgnutls: When checking openpgp self signature also check the signatures
1626 Ilari Liusvaara noticed and reported the issue and provided test
1629 ** libgnutls: Cleanups and several bug fixes.
1630 Found by Steve Grubb and Tomas Mraz.
1632 ** Link libgcrypt explicitly to certtool, gnutls-cli, gnutls-serv.
1634 ** Fix --disable-valgrind-tests.
1635 Reported by Ingmar Vanhassel in
1636 <https://savannah.gnu.org/support/?107029>.
1638 ** examples: Use the new APIs for printing X.509 certificate information.
1640 ** Fix build failures on Solaris.
1641 Thanks to Dagobert Michelsen <dam@opencsw.org>.
1643 ** i18n: Updated Czech, Dutch, French, Polish, Swedish and Vietnamese
1644 ** translations. Added Simplified Chinese translation.

1675 The patch to resolve the X.509 CN/SAN issue accidentally broken
1676 OpenPGP hostname comparison.
1678 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1679 Reported by Howard Chu <hyc@symas.com> in
1680 <https://savannah.gnu.org/support/?106975>.
1682 ** API and ABI modifications:
1683 No changes since last version.
1685 * Version 2.8.3 (released 2009-08-13)
1687 ** libgnutls: Fix patch for NUL in CN/SAN in last release.
1688 Code intended to be removed would lead to an read-out-bound error in
1689 some situations. Reported by Tomas Hoger <thoger@redhat.com>. A CVE
1690 code have been allocated for the vulnerability: [CVE-2009-2730].
1692 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1693 The function may fail incorrectly when an earlier certificate was
1694 imported to the same gnutls_x509_crt_t structure.
1696 ** libgnutls-extra, libgnutls-openssl: Fix MinGW cross-compiling build error.
1698 ** tests: Made self-test mini-eagain take less time.
1702 ** API and ABI modifications:
1703 No changes since last version.
1705 * Version 2.8.2 (released 2009-08-10)
1707 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1708 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1709 into 1) not printing the entire CN/SAN field value when printing a
1710 certificate and 2) cause incorrect positive matches when matching a
1711 hostname against a certificate. Some CAs apparently have poor
1712 checking of CN/SAN values and issue these (arguable invalid)
1713 certificates. Combined, this can be used by attackers to become a
1714 MITM on server-authenticated TLS sessions. The problem is mitigated
1715 since attackers needs to get one certificate per site they want to
1716 attack, and the attacker reveals his tracks by applying for a
1717 certificate at the CA. It does not apply to client authenticated TLS
1718 sessions. Research presented independently by Dan Kaminsky and Moxie
1719 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1720 for providing one part of the patch. [GNUTLS-SA-2009-4].
1722 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1723 Before it always returned false. Reported by Peter Hendrickson
1724 <pdh@wiredyne.com> in
1725 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3668>.
1727 ** libgnutls: Fix off-by-one size computation error in unknown DN printing.
1728 The error resulted in truncated strings when printing unknown OIDs in
1729 X.509 certificate DNs. Reported by Tim Kosse
1730 <tim.kosse@filezilla-project.org> in
1731 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3651>.
1733 ** libgnutls: Return correct bit lengths of some MPIs.
1734 gnutls_dh_get_prime_bits, gnutls_rsa_export_get_modulus_bits, and
1735 gnutls_dh_get_peers_public_bits. Before the reported value was
1736 overestimated. Reported by Peter Hendrickson <pdh@wiredyne.com> in
1737 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3607>.
1739 ** libgnutls: Avoid internal error when invoked after GNUTLS_E_AGAIN.

1741 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3671>
1743 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3670>.
1745 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1746 Before we required that the runtime library used the same (or more
1747 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1748 that the runtime usage is above the minimum required. Reported by
1749 Marco d'Itri <md@linux.it> via Andreas Metzler
1750 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.

1765 ** libgnutls: Fix PKCS#12 decryption from password.
1766 The encryption key derived from the password was incorrect for (on
1767 average) 1 in every 128 input for random inputs. Reported by "Kukosa,
1768 Tomas" <tomas.kukosa@siemens-enterprise.com> in
1769 <http://permalink.gmane.org/gmane.network.gnutls.general/1663>.

1881 No offically supported interfaces have been modified or removed. The
1882 library should be completely backwards compatible on both the source
1885 The shared library no longer exports some symbols that have never been
1886 officially supported, i.e., not mentioned in any of the header files.
1892 Normally when symbols are removed, the shared library version has to
1893 be incremented. This leads to a significant cost for everyone using
1894 the library. Because none of the above symbols have ever been
1895 intended for use by well-behaved applications, we decided that the it
1896 would be better for those applications to pay the price rather than
1897 incurring problems on the majority of applications.
1899 If it turns out that applications have been using unofficial
1900 interfaces, we will need to release a follow-on release on the v2.8
1901 branch to exports additional interfaces. However, initial testing
1902 suggests that few if any applications have been using any of the
1905 Although not a new change compared to 2.6.x, we'd like to remind you
1906 interfaces have been modified so that X.509 chain verification now
1907 also checks activation/expiration times on certificates. The affected
1910 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
1911 gnutls_certificate_verify_peers: Likewise.
1912 gnutls_certificate_verify_peers2: Likewise.
1913 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
1914 GNUTLS_CERT_EXPIRED: ADDED.
1915 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
1917 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
1918 we gave our rationale for it in earlier release notes.
1920 The following symbols have been added to the library:
1922 gnutls_certificate_set_x509_simple_pkcs12_mem: ADDED
1923 gnutls_x509_crl_get_authority_key_id: ADDED

2087 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2088 We also add a new gnutls_certificate_verify_flags flag,

2090 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2092 ** lib: Linker version scripts reduces number of exported symbols.
2093 The linker version script now lists all exported ABIs explicitly, to
2094 avoid accidentally exporting unintended functions. Compared to
2095 before, most symbols beginning with _gnutls* are no longer exported.
2096 These functions have never been intended for use by applications, and
2097 there were no prototypes for these function in the public header
2098 files. Thus we believe it is possible to do this without incrementing
2099 the library ABI version which normally has to be done when removing an
2102 ** lib: Limit exported symbols on systems without LD linker scripts.
2103 Before all symbols were exported. Now we limit the exported symbols
2104 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2105 _gnutls*. This is a superset of the actual supported ABI, but still
2106 an improvement compared to before. This is implemented using Libtool
2107 -export-symbols-regex. It is more portable than linker version
2110 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2111 This should have been done in the last release.

2118 We now follow the advice given by the texinfo manual on which
2119 directory categories to use. In particular, libgnutls moved from the
2120 'GNU Libraries' section to the 'Software libraries' and the command

2134 ** libgnutls: Applied patch by Cedric Bail to add functions
2135 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2137 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.

2142 GnuTLS is also internally ready to be used with libtasn1 v2.0.
2144 ** doc: Fix build failure of errcodes/printlist.
2145 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
2146 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
2148 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2149 It is currently only used by the core library. This will enable a new
2150 domain 'gnutls' for translations of the command line tools.
2152 ** Corrected possible memory corruption on signature verification failure.

2161 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2162 This applies both to generating certificates and certificate requests.
2164 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2166 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2167 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2168 be used for chain verification.
2170 ** gnutls-serv: No longer disable MAC padding by default.
2171 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2173 ** gnutls-cli: Certificate information output format changed.
2174 The tool now uses libgnutls' functions to print certificate
2175 information. This avoids code duplication.
2177 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2178 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2179 They can be used to override the default certificate chain validation
2182 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2183 specify the client hello message record version. Used to overcome buggy
2184 TLS servers. Report by Martin von Gagern.
2186 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2188 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.

2192 ** API and ABI modifications:
2193 No changes since last version.
2195 * Version 2.7.5 (released 2009-02-06)
2197 ** libgnutls: Accept chains where intermediary certs are trusted.
2198 Before GnuTLS needed to validate the entire chain back to a
2199 self-signed certificate. GnuTLS will now stop looking when it has
2200 found an intermediary trusted certificate. The new behaviour is
2201 useful when chains, for example, contains a top-level CA, an
2202 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2203 To avoid chain validation errors due to the RSA-MD5 cert, you can
2204 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2205 The signature on trusted certificates are not checked, so the chain
2206 has a chance to validate correctly. Reported by "Douglas E. Engert"

2210 ** libgnutls: result_size in gnutls_hex_encode now holds
2211 the size of the result. Report by John Brooks <special@dereferenced.net>.
2213 ** libgnutls: gnutls_handshake when sending client hello during a
2214 rehandshake, will not offer a version number larger than the current.
2215 Reported by Tristan Hill <stan@saticed.me.uk>.
2217 ** libgnutls: Permit V1 Certificate Authorities properly.
2218 Before they were mistakenly rejected even though
2219 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2220 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by

2225 No changes since last version.
2227 * Version 2.7.4 (released 2009-01-07)
2229 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2230 This is a bugfix -- the previous attempt to do this from internal x509
2231 certificate verification procedures did not return the correct value
2232 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2233 <dkg@fifthhorseman.net> in

2239 Patch from David MarÃn Carreño <davefx@gmail.com> in
2240 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2242 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2244 ** certtool: --verify-chain now prints results of using library verification.
2245 Earlier, certtool --verify-chain used its own validation algorithm
2246 which wasn't guaranteed to give the same result as the libgnutls
2247 internal validation algorithm. Now this command print a new final
2248 line with header 'Chain verification output:' that contains the result
2249 from using the internal verification algorithm on the same chain.

2264 ** libgnutls: Libgcrypt initialization changed.
2265 If libgcrypt has not already been initialized, GnuTLS will now
2266 initialize libgcrypt with disabled secure memory. Initialize
2267 libgcrypt explicitly in your application if you want to enable secure
2268 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2269 allocation functions, which doesn't use secure memory, so there is no
2270 real change in behaviour.
2272 ** libgnutls: Fix memory leak in PSK authentication.
2273 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2274 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2276 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2278 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2279 It needs to be invoked before libgcrypt is initialized.
2281 ** gnutls-cli: Return non-zero exit code on error conditions.
2283 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2285 ** tests: Added chainverify self-test that tests X.509 chain verifications.

2292 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2293 The flaw makes it possible for man in the middle attackers (i.e.,
2294 active attackers) to assume any name and trick GnuTLS clients into
2295 trusting that name. Thanks for report and analysis from Martin von

2302 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
2303 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2304 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2305 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2306 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to

2393 Patch by ludo@gnu.org (Ludovic Courtès).
2395 ** Changed detection of libtasn1 and libgcrypt to avoid depending on *-config.

2432 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2433 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2434 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2436 ** libgnutls: Check expiration/activation time on untrusted certificates.
2437 Reported by Romain Francoise <romain@orebokech.com>. Before the
2438 library did not check activation/expiration times on certificates, and
2439 was documented as not doing so. We have realized that many
2440 applications that use libgnutls, including gnutls-cli, fail to perform
2441 proper checks. Implementing similar logic in all applications leads
2442 to code duplication. Hence, we decided to check whether the current
2443 time (as reported by the time function) is within the
2444 activation/expiration period of certificates when verifying untrusted
2447 This changes the semantics of gnutls_x509_crt_list_verify, which in
2448 turn is used by gnutls_certificate_verify_peers and
2449 gnutls_certificate_verify_peers2. We add two new
2450 gnutls_certificate_status_t codes for reporting the new error
2451 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2452 add a new gnutls_certificate_verify_flags flag,

2601 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2602 from Thomas Viehmann <tv@beamnet.de>.
2604 ** certtool: Use inet_pton for parsing IPv6 addresses.
2606 ** Major changes compared to the v2.4 branch:
2608 *** Added API to replace and update the crypto backend.
2610 *** certtool: can add several subject alternative names via template file.
2612 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2614 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2615 either set or append alternative names. It can also handle binary structures
2616 such as IP addresses.
2618 *** libgnutls: New function to set minimum acceptable SRP bits.
2619 The function is gnutls_srp_set_prime_bits.
2621 *** libgnutls: Add interface to deal with public key and signature algorithms.
2622 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2623 gnutls_sign_list, and gnutls_sign_get_id.
2625 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2626 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2628 *** libgnutls: New API to get a string corresponding to a error symbol.
2629 The function is gnutls_strerror_name.
2631 *** libgnutls: New API to set the public parameters in a certificate request
2632 *** from a private key.
2633 The function is gnutls_x509_crq_set_key_rsa_raw.
2635 *** libgnutls: New API to set a callback to extract TLS Finished data.
2636 The function to register is gnutls_session_set_finished_function and
2637 it takes a callback of the gnutls_finished_callback_func type.
2639 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2641 *** libgnutls: New interface to register a new TLS extension handler.
2642 The new function gnutls_ext_register can be used to register handlers
2643 for specific TLS extension types. The callback functions have the new
2644 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2645 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2648 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2649 The function is gnutls_register_md5_handler. When libgcrypt is in
2650 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2653 *** API/ABI changes in GnuTLS 2.6
2654 No functions have been removed or modified. The library should be
2655 fully backwards compatible on both the source and binary level.
2657 A new header file <gnutls/crypto.h> have been added. It contains
2658 definitions related to replacing the internal crypto functionality.
2659 All definitions and the header itself is experimental but supported.
2661 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2662 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2663 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2665 The following functions have been added to libgnutls:
2669 gnutls_crypto_bigint_register2

2708 The parameters are now allocated in the structure itself.
2710 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
2712 ** tests: Scripts now use EXEEXT properly.
2713 Modern libtool doesn't create wrapper script, so the self tests need
2714 to invoke certtool.exe under MinGW32+Wine.
2716 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
2717 Automake warnings are now also enabled.
2719 ** API and ABI modifications:
2720 gnutls_pk_params_st: MODIFIED
2722 * Version 2.5.8 (released 2008-09-21)
2724 ** certtool: updated so it can add several subject alternative names using
2727 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2728 either set or append alternative names. It can also handle binary structures
2729 such as IP addresses.
2731 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
2733 ** libgnutls: New function to set minimum acceptable SRP bits.
2734 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick
2735 <quick@sparq.org> in <https://savannah.gnu.org/support/index.php?106454>.
2737 ** libgnutls: Check for overflows in gnutls_calloc and gnutls_secure_calloc.

2815 ** libgnutls: Fix segmentation fault when generating private keys.
2816 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2818 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
2819 The code has not worked since v0.9.0 and apparently nobody has missed
2820 it, so we decided to remove the code rather than fix it. If you have
2821 old certificate chains stored in PKCS#7 format, you can convert them
2822 to a list of PEM certificates by using 'certtool --p7-info'. Reported
2823 by Christian Grothoff <christian@grothoff.org>.
2825 ** opencdk: Parse (but not decrypt) encrypted secret keys.
2826 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.

2848 No changes since last version.
2850 * Version 2.5.3 (released 2008-08-14)
2852 ** libgnutls: New API to set the public parameters in a certificate request
2853 ** from a private key.
2854 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
2855 discussion with "Zach C." <fxchip@gmail.com>.
2857 ** libgnutls: New API to set a callback to extract TLS Finished data.
2858 The function to register is gnutls_session_set_finished_function and
2859 it takes a callback of the gnutls_finished_callback_func type.
2861 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
2862 Reported in <https://savannah.gnu.org/support/?106453>.
2864 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2865 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
2866 names are mapped to the new names in compat.h. These mappings will
2867 likely be removed more quickly than other mappings in that file due to
2868 the namespace violation.
2870 ** libgnutlsxx: Make it build when SRP is disabled.
2872 ** doc: Add doxygen files in doc/doxygen/.
2874 ** API and ABI modifications:

2880 TLS_MASTER_SIZE: DEPRECATED
2881 TLS_RANDOM_SIZE: DEPRECATED
2883 * Version 2.5.2 (released 2008-07-08)
2885 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
2886 The prime and generator was swapped.
2888 ** libgnutls: New interface to register a new TLS extension handler.
2889 The new function gnutls_ext_register can be used to register handlers
2890 for specific TLS extension types. The callback functions have the new
2891 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2892 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2895 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
2896 This was made possible by using the new gnutls_ext_register interface.
2897 The TLS/IA functionality has only been supported through the
2898 libgnutls-extra library, so it makes sense for the code to belong
2901 ** API and ABI modifications:

2911 ** API and ABI modifications:
2912 No changes since last version.
2914 * Version 2.5.0 (released 2008-07-02)
2916 ** Port fixes from v2.4.1 release, see below.
2918 ** Added API to replace and update the crypto backend.
2919 The header gnutls/crypto.h is now officially supported, and declares
2922 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
2924 ** Update gnulib and translations.
2925 The gnulib gc crypto code has been removed since it was never finished
2926 and is no longer even used. An internal non-libgcrypt crypto
2927 implementation may be added in the future, but we'll decide that later

2939 gnutls_crypto_single_mac_register2: ADDED.
2941 * Version 2.4.3 (released 2009-02-06)
2943 ** libgnutls: Accept chains where intermediary certs are trusted.
2944 Before GnuTLS needed to validate the entire chain back to a
2945 self-signed certificate. GnuTLS will now stop looking when it has
2946 found an intermediary trusted certificate. The new behaviour is
2947 useful when chains, for example, contains a top-level CA, an
2948 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2949 To avoid chain validation errors due to the RSA-MD5 cert, you can
2950 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2951 The signature on trusted certificates are not checked, so the chain
2952 has a chance to validate correctly. Reported by "Douglas E. Engert"
2953 <deengert@anl.gov> in
2954 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2956 ** libgnutls: Permit V1 Certificate Authorities properly.
2957 Before they were mistakenly rejected even though
2958 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2959 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2960 "Douglas E. Engert" <deengert@anl.gov> in
2961 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2963 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2964 This is a bugfix -- the previous attempt to do this from internal x509
2965 certificate verification procedures did not return the correct value
2966 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2967 <dkg@fifthhorseman.net> in
2968 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,

3064 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3065 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3066 The old parameters will continue to work for some time.
3068 *** Certtool now confirm passwords and changes permissions of private key files.
3070 *** The default handshake size limit has been increased to 48kb.
3071 It appears as if some valid handshakes are large due to sending many
3072 CA certificates. (The earlier limit was 16kb.)
3074 *** LZO compression is now disabled by default.
3075 The main reason is that LZO compression in TLS is not standardized,
3076 but license compatiblity issues with minilzo triggered us to make this
3079 *** Improvements for cross-compilation to Windows and OpenWRT.
3081 *** The look of the GTK-DOC manual has been improved.
3082 Major developer visible changes compared to the v2.2 branch:
3084 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3086 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3087 *** elements from the certificate credentials structure.
3088 Thanks to Joe Orton.
3090 *** New APIs to improve working with username/passwords and PSK.
3092 *** Names of constants to affect certificate printing changed.
3093 The constants are used for OpenPGP too, which the names didn't
3094 reflect, so the following name change has been made:
3097 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3098 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3099 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3101 The old names will be mapped to the new names for some time.
3103 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3104 *** gnutls_openpgp_privkey_get_key_id.
3105 A compatibility mapping exists to avoid breaking API backwards
3108 *** Replaced all uses of alloca with malloc and free.
3110 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3111 We have been unable to find a documented rationale for this practice.
3113 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3115 *** API/ABI changes in GnuTLS 2.4
3116 All OpenPGP related functions have been moved from libgnutls-extra to
3117 libgnutls, and several new functions have been added (see below).
3118 Before making the release, we discussed whether moving functions from
3119 libgnutls-extra to libgnutls would require us to increment the ABI
3120 version, but the general opinion was that this would not be required.
3121 All older functions continue to work the same. We are open to the
3122 possibility that this decision will lead to problem on some platform,
3123 and if it turns out that the Right Thing should have been to increment
3124 the shared library version, we would need to release an update within
3125 the 2.4.x branch that increments the shared library version.
3127 This release adds the following functions:
3129 gnutls_psk_client_get_hint
3130 gnutls_psk_set_server_credentials_hint
3131 gnutls_psk_netconf_derive_key
3133 Used to get/set the PSK identity hint, and derive PSK keys from
3134 passwords a'la netconf.
3136 gnutls_x509_dn_deinit
3137 gnutls_x509_dn_export
3138 gnutls_x509_dn_import
3141 Used to handle X.509 Certificate DN's directly.
3145 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3148 gnutls_certificate_get_x509_cas
3149 gnutls_certificate_get_x509_crls
3150 gnutls_certificate_get_openpgp_keyring
3152 Functions for direct access to credential elements.

3192 gnutls_openpgp_privkey_get_subkey_revoked_status
3193 gnutls_openpgp_privkey_set_preferred_key_id
3195 New OpenPGP related functions.
3197 The function gnutls_openpgp_crt_get_key_id is the same as the old
3198 from gnutls_openpgp_crt_get_id, see above.
3200 The release also adds a new header file 'gnutls/crypto.h', however it
3201 is currently not used.
3203 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
3204 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3206 ** API and ABI modifications:
3207 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.
3208 gnutls_openpgp_privkey_get_subkey_fingerprint: ADDED.
3210 * Version 2.3.15 (released 2008-06-15)
3212 ** Disable the openpgp-certs self-tests.
3213 It results in failure under Wine and doesn't work on Debian buildds.
3215 ** API and ABI modifications:
3216 No changes since last version.
3218 * Version 2.3.14 (released 2008-06-11)
3220 ** libgnutls [OpenPGP]: Changed OpenPGP verification behaviour.
3221 An OpenPGP certificate is now only considered verified if all the user
3224 ** Examples: Make C++ example compile.
3225 Earlier it may have failed with an unresolved reference to strlen.
3227 ** Documentation: Doc fix for gnutls_x509_crt_get_extension_oid.
3228 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
3230 ** API and ABI modifications:
3231 No changes since last version.
3233 * Version 2.3.13 (released 2008-06-07)
3235 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3237 ** doc/: Add psktool to info index. Some minor cleanups.
3239 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3241 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3242 The file suppresses the known libgcrypt memory leaks, so they aren't
3243 printed when you run valgrind on the gnutls self-tests. Use it as
3244 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
3245 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
3248 ** tests/: Reduce amount of debugging output by default.
3249 Use --verbose for each test to get the full output.
3251 ** tests/: Fix memory leaks in several self-tests.
3252 None of the self tests should be leaking memory when running valgrind
3253 or similar tools. (Known exceptions are dhepskself, pskself, and
3254 set_pkcs12_cred, which appear likely to be due to memory leaks in the
3257 ** API and ABI modifications:
3258 No changes since last version.
3260 * Version 2.3.12 (released 2008-06-04)
3262 ** Merge gnutls_with_netconf branch.
3264 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
3265 The function is gnutls_psk_client_get_hint.
3267 *** libgnutls [PSK]: New API to set PSK identity hint in server.
3268 The function is gnutls_psk_set_server_credentials_hint.
3270 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3271 In the client, the message is parsed and the application can use
3272 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3273 message is sent if the application has specified a PSK identity hint
3274 using gnutls_psk_set_server_credentials_hint.
3276 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3277 The function gnutls_psk_netconf_derive_key supports the PSK key
3278 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3281 *** psktool: Support new --netconf-hint to generate PSK key from password.
3282 Uses the Netconf algorithm to derive PSK key from password.
3284 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3286 *** gnutls-cli: Always support PSK modes, through a callback.
3287 The callback will derive a PSK key using Netconf algorithm. It will
3288 print the PSK identity hint to help the user.
3290 *** New PSK example client and server.
3291 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3293 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3294 The code didn't work properly on platforms where 'char' is unsigned,
3295 when you set version 0. Reported by Laurence Withers
3296 <l@lwithers.me.uk> in
3297 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2825>.
3299 ** libgnutls-openssl: added RAND_pseudo_bytes API.
3300 Patch from Robert Millan <rmh@aybabtu.com>.
3302 ** API and ABI modifications:
3303 RAND_pseudo_bytes: ADDED to libgnutls-openssl.
3304 gnutls_psk_client_get_hint: ADDED.
3305 gnutls_psk_set_server_credentials_hint: ADDED.
3306 gnutls_psk_netconf_derive_key: ADDED
3308 * Version 2.3.11 (released 2008-05-20)
3310 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3311 The flaw would result in incorrectly terminated sessions with the
3312 error "Decryption has failed" when the server sends a small packet
3313 (typically when the session is closed). Reported by Andreas Metzler
3314 <ametzler@downhill.at.eu.org> in
3315 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3317 ** Don't use gnulib headers when building C++ library.
3318 Fixes builds under Windows.
3320 ** Make umask a requirement.
3321 We don't know of any system that lacks it, even GNU CoreUtils use it
3324 ** Update gnulib files.
3325 Fixes a problem where it pulled in a replacement for memcmp under
3326 MinGW, which caused the C++ example to fail to build.
3328 ** API and ABI modifications:
3329 No changes since last version.
3331 * Version 2.3.10 (released 2008-05-19)
3333 ** Added wide wildcard hostname matching.
3334 Tiny patch by Jean-Philippe Garcia Ballester.
3336 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3337 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3338 which allowed the bugs to be reproduced and fixed easily. Patches
3339 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3340 with more details about these vulnerabilities will be added to
3341 <http://www.gnu.org/software/gnutls/security.html>
3343 *** [GNUTLS-SA-2008-1-1]
3344 *** libgnutls: Fix crash when sending invalid server name.
3345 The crash can be triggered remotely before authentication, which can
3346 lead to a Daniel of Service attack to disable the server. The bug
3347 cause gnutls to store more session resumption data than what was
3348 allocated for, thus overwriting unallocated memory.
3350 *** [GNUTLS-SA-2008-1-2]
3351 *** libgnutls: Fix crash when sending repeated client hellos.
3352 The crash can be triggered remotely before authentication, which can
3353 lead to a Daniel of Service attack to disable the server. The bug
3354 triggers a null-pointer dereference.
3356 *** [GNUTLS-SA-2008-1-3]
3357 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3358 The crash can be triggered remotely before authentication, which can
3359 lead to a Daniel of Service attack to disable the server. The bug
3360 cause gnutls to read memory beyond the end of the received record.
3362 ** libgnutlsxx: Updated API according to patches from Eduardo
3363 Villanueva Che (discussion at
3364 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3366 ** Use umask to restrict permissions to owner before creating a file.
3368 ** API and ABI modifications:
3369 No changes since last version.
3371 * Version 2.3.9 (released 2008-05-16)
3373 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3374 Based on report and tiny patches from
3375 <jared.jennings.ctr@eglin.af.mil>, see
3376 <https://savannah.gnu.org/support/index.php?106342>.
3378 ** libgnutls: Translation fixes.
3380 ** gnutls-cli: Fix so that PSK authentication works.
3381 Also improve manual to give example for gnutls-cli PSK authentication.
3383 ** certtool: Encrypting a private key now require a confirmed password.
3384 Before './certtool -k -8' would merely ask for a password once.
3385 Reported by Daniel 'NebuchadnezzaR' Dehennin
3386 <nebuchadnezzar@asgardr.info> see
3387 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3389 ** certtool: When writing private keys to files, change permissions of file.
3390 Now the file which the private key is saved to is chmod'ed 0600.
3391 Reported by martin f krafft <madduck@debian.org> see
3392 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3394 ** guile: Fix -fgnu89-inline test.
3396 ** Removed --enable-profile-mode.
3397 The code linked gnutls with the libfc project (Function Check) which
3398 appears to have been stalled since around 2002.
3400 ** Clean up header file checks by ./configure.
3402 ** Update of gnulib files.
3404 ** API and ABI modifications:
3405 No changes since last version.
3407 * Version 2.3.8 (released 2008-04-29)
3409 ** libgnutls: Increase default handshake packet size limit to 48kb.
3410 The old limit was 16kb and some servers send huge list of trusted CAs,
3411 thus running into the limit. FYI, applications can further increase
3412 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3413 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3414 <marc@mclemente.net> for reporting and providing test servers.
3416 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3417 Returned when the handshake data size is too large. Before
3418 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3421 ** libgnutls: Hide definitions in crypto.h.
3422 We have decided that the APIs defined in crypto.h are not stable
3423 enough for v2.4, so don't use any of those functions.
3425 ** gnutls-cli: exit when hostname doesn't match certificate.
3426 Use --insecure to avoid hostname comparison.
3428 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3429 The reason is to align terminology with OpenPGP, which doesn't use
3430 DER. The old parameters will continue to work for some time.
3432 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3434 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3436 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3437 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3438 vasprintf symbol from the libgcrypt library which caused problems.
3440 ** Update of gnulib files.
3442 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3444 ** API and ABI modifications:
3445 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3447 * Version 2.3.7 (released 2008-04-21)
3449 ** opencdk now properly sets the key usage bits into openpgp keys.
3451 ** gnutls-cli: Fix crash on TLS handshake failures.
3452 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3453 This is similar to <http://bugs.debian.org/429183>.
3455 ** certtool: with --generate-request and newly generated keys, print the key.
3457 ** Build fixes for MinGW.
3458 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3459 with -lws2_32 when needed. Use ASCII only isprint() when printing
3460 X.509 certificate information, to avoid non-ASCII but printable
3461 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3464 ** Update internal copy of libtasn1 to version 1.4.
3466 ** API and ABI modifications:
3467 No changes since last version.
3469 * Version 2.3.6 (released 2008-04-17)
3471 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3472 ** Improve documentation for gnutls_x509_crq_sign2.
3473 Based on report from "John Brooks" <aspecialj@gmail.com> in
3474 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3476 ** tests/pathlen: run diff without parameters to improve portability.
3477 Based on HPUX build hints in
3478 <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>.

3481 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3482 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3484 ** Remove all uses of gnutls_alloca/gnutls_afree.
3485 Use normal gnutls_malloc instead. One reason is increased portability
3486 to Windows, the other is that several of the uses may be unsafe
3487 because the size of data allocated could be large. Reported by
3488 Massimo Gaspari <massimo.gaspari@alice.it> in
3489 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3491 ** Build Guile code with -fgnu89-inline only when supported.
3492 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3493 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3495 ** Several GTK-DOC related fixes.
3497 ** Clean up OpenCDK related code.
3498 GnuTLS now requires its internal OpenCDK code rather than the external
3499 GPL library OpenCDK. Unfortunately, we don't have resources to
3500 maintain an external library (help welcome).
3502 ** API and ABI modifications:
3503 No changes since last version.
3505 * Version 2.3.5 (released 2008-04-14)
3507 ** Build fix for MinGW and --disable-shared.
3508 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in

3511 ** Document how to generate CRLs.
3512 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3514 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3516 ** Several minor fixes in the OpenPGP interface.
3517 Thanks to Daniel Kahn Gillmor.
3519 ** Fix fopen file descriptor leak in PSK server code.
3520 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3521 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3523 ** Translations files not stored directly in git to avoid merge conflicts.
3525 ** New APIs to let applications replace the RNG used.
3526 Update all RNG callers in the code to use the new interface.
3528 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3530 ** Update gnulib files.
3532 ** API and ABI modifications:
3533 gnutls_crypto_rnd_register: ADDED
3534 gnutls_rnd_level_t: ADDED
3535 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3536 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3537 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3538 gnutls_crypto_rnd_st: ADDED
3539 GNUTLS_DIG_SHA224: ADDED
3540 GNUTLS_SIGN_RSA_SHA224: ADDED
3541 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3543 * Version 2.3.4 (released 2008-03-19)
3545 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3546 They weren't renamed in the public header file.
3548 ** Added functions to register a cipher/mac/digest. This allows to
3549 override the included ones.
3551 ** Fix a bunch of compiler warnings.
3553 ** API and ABI modifications:
3554 gnutls_crypto_cipher_st: ADDED
3555 gnutls_crypto_mac_st: ADDED
3556 gnutls_crypto_digest_st: ADDED
3557 gnutls_crypto_cipher_register: ADDED
3558 gnutls_crypto_mac_register: ADDED
3559 gnutls_crypto_digest_register: ADDED
3560 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3562 * Version 2.3.3 (released 2008-03-10)
3564 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3565 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3567 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3568 We could not find any modern justification for enabling these flags by
3569 default. If you know of some platform that needs one of the flags to
3570 work properly, please let us know. (Actually introduced in v2.3.0 but
3571 not documented until now.)
3573 ** Importing many CA certificates are now considerably faster.
3574 This affect gnutls_certificate_set_x509_trust_mem,
3575 gnutls_certificate_set_x509_trust, and
3576 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3577 from O(2*n^2) to O(n). When adding 206 files containing 408
3578 certificates, using gnutls_certificate_set_x509_trust_file, the time
3579 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3580 to trigger the problem. See also

3604 ** Fix srcdir!=objdir failure in openpgpself test.
3606 ** Improved API documentation output from GTK-DOC.
3608 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3610 ** Renamed gnutls_certificate_export_x509_cas and friends.
3611 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.

3707 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
3708 old GNUTLS_X509_CRT_UNSIGNED_FULL.
3710 * Version 2.3.0 (released 2008-01-08)
3712 ** LZO compression is now disabled by default.
3713 The reason is that LZO compression is not standardized in TLS. If you
3714 wish to experiment with it, you will have to supply --with-lzo when
3715 invoking ./configure. The internal copy of minilzo is no longer
3716 included with GnuTLS, so you will need to install liblzo or liblzo2 on
3717 your system to have --with-lzo to be effective.
3719 ** More than one server name field is now sent to the server properly.
3720 Thanks to mark.phillips@virgin.net.
3722 ** Fixes the post_client_hello_function(). The extensions are now parsed
3723 in a callback friendly way.
3725 ** Fix for certificate selection in servers with certificate callbacks.
3727 ** Updated translations.
3729 ** Update gnulib files.
3731 ** API and ABI modifications:
3732 No changes since last version.
3734 * Version 2.2.5 (released 2008-05-19)
3736 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3737 The flaw would result in incorrectly terminated sessions with the
3738 error "Decryption has failed" when the server sends a small packet
3739 (typically when the session is closed). Reported by Andreas Metzler
3740 <ametzler@downhill.at.eu.org> in
3741 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3743 ** API and ABI modifications:
3744 No changes since last version.
3746 * Version 2.2.4 (released 2008-05-19)
3748 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3749 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3750 which allowed the bugs to be reproduced and fixed easily. Patches
3751 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3752 with more details about these vulnerabilities will be added to
3753 <http://www.gnu.org/software/gnutls/security.html>
3755 *** [GNUTLS-SA-2008-1-1]
3756 *** libgnutls: Fix crash when sending invalid server name.
3757 The crash can be triggered remotely before authentication, which can
3758 lead to a Daniel of Service attack to disable the server. The bug
3759 cause gnutls to store more session resumption data than what was
3760 allocated for, thus overwriting unallocated memory.
3762 *** [GNUTLS-SA-2008-1-2]
3763 *** libgnutls: Fix crash when sending repeated client hellos.
3764 The crash can be triggered remotely before authentication, which can
3765 lead to a Daniel of Service attack to disable the server. The bug
3766 triggers a null-pointer dereference.
3768 *** [GNUTLS-SA-2008-1-3]
3769 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3770 The crash can be triggered remotely before authentication, which can
3771 lead to a Daniel of Service attack to disable the server. The bug
3772 cause gnutls to read memory beyond the end of the received record.
3774 ** API and ABI modifications:
3775 No changes since last version.
3777 * Version 2.2.3 (released 2008-05-06)
3779 ** Increase default handshake packet size limit to 48kb.
3780 The old limit was 16kb and some servers send huge list of trusted CAs,
3781 thus running into the limit. FYI, applications can further increase
3782 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3783 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3784 <marc@mclemente.net> for reporting and providing test servers.
3786 ** Fix compilation error related to __FUNCTION__ on some systems.
3787 Reported by Tim Mooney, see
3788 <https://savannah.gnu.org/support/?106267>.
3790 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3792 ** Fix fopen file descriptor leak in PSK server code.

3802 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
3804 ** API and ABI modifications:
3805 No changes since last version.
3807 * Version 2.2.2 (released 2008-02-21)
3809 ** Cipher priority string handling now handle strings that starts with NULL.
3810 Thanks to Laurence Withers <l@lwithers.me.uk>.
3812 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3815 ** Increased the default certificate verification chain limits and allowed
3816 for checks without limitation.
3818 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3819 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3820 strings and return the proper size.
3822 ** API and ABI modifications:
3823 No changes since last version.
3825 * Version 2.2.1 (released 2008-01-17)
3827 ** Prevent linking libextra against previously installed libgnutls.
3828 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
3829 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
3831 ** Fixes the post_client_hello_function(). The extensions are now parsed
3832 in a callback friendly way.
3834 ** Fix for certificate selection in servers with certificate callbacks.
3836 ** API and ABI modifications:
3837 No changes since last version.
3839 * Version 2.2.0 (released 2007-12-14)
3841 ** Update internal copy of libtasn1 to version 1.2.
3843 ** Certtool --verify-chain now handle inputs larger than 64kb.
3844 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
3845 recent versions of libgcrypt. The problem was that Wine with the
3846 libgcrypt RNG generates huge amounts of debugging output.
3848 ** Translation updates.
3849 Added Dutch translation. Updated Polish and Swedish translation.
3851 ** Major changes compared to the v2.0 branch:
3853 *** SRP support aligned with newly published RFC 5054.
3855 *** OpenPGP support aligned with newly published RFC 5081.
3857 *** Support for DSA2 keys.
3859 *** Support for Camellia cipher.
3861 *** Support for Opaque PRF Input extension.
3863 *** PKCS#8 parser now handle DSA keys.
3865 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
3866 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
3867 versions, such as 2.01 which is included with GnuTLS, is available
3868 under GPLv2 or later. If this incompatibility causes problems, we
3869 recommend you to disable LZO using --without-lzo. LZO compression is
3870 not a standard TLS compression algorithm, so the impact should be
3873 *** Functions for disabling record protocol padding.
3874 Works around bugs on Nokia/Ericsson phones.
3876 *** New functions gnutls_priority_set() for setting cipher priorities easily.
3877 Priorities like "COMPAT" also enables other work arounds, such as
3880 *** Other minor improvements and bug fixes.
3882 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
3883 To adapt to changes in the TLS extension specifications for OpenPGP
3884 and SRP, the GnuTLS API had to be modified. This means breaking the
3885 API and ABI backwards compatibility. That is something we try to
3886 avoid unless it is necessary. We decided to also remove the already
3887 deprecated stub functions for X.509 to XML conversion and TLS
3888 authorization (see below) when we had the opportunity.
3890 Generally, most applications does not need to be modified. Just
3891 re-compile them against the latest GnuTLS release, and it should work
3894 Applications that use the OpenPGP or SRP features needs to be
3895 modified. Below is a list of the modified APIs and discussion of what
3896 the minimal things you need to modify in your application to make it
3897 work with GnuTLS 2.2.
3899 Note that GnuTLS 2.2 also introduces new APIs -- such as
3900 gnutls_set_priority() that is superior to
3901 gnutls_set_default_priority() -- that you may want to start using.
3902 However, using those new APIs is not required to use GnuTLS 2.2 since
3903 the old functions continue are still supported. This text only
3904 discuss what you minimally have to modify.
3906 *** XML related changes
3907 The function `gnutls_x509_crt_to_xml' has been removed. It has been
3908 deprecated and only returned an error code since GnuTLS version
3909 1.2.11. Nobody has complained, so users doesn't seem to miss the
3910 functionality. We don't know of any other library to convert X.509
3911 certificates into XML format, but we decided (long ago) that GnuTLS
3912 isn't the right place for this kind of functionality. If you want
3913 help to find some other library to use here, please explain and
3914 discuss your use case on help-gnutls@gnu.org.
3916 *** TLS Authorization related changes
3917 Everything related to TLS authorizations have been removed, they were
3918 only stub functions that returned an error code:
3920 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
3921 gnutls_authz_data_format_type_t
3922 gnutls_authz_recv_callback_func
3923 gnutls_authz_send_callback_func
3925 gnutls_authz_send_x509_attr_cert
3926 gnutls_authz_send_saml_assertion
3927 gnutls_authz_send_x509_attr_cert_url
3928 gnutls_authz_send_saml_assertion_url
3930 *** SRP related changes
3931 The callback gnutls_srp_client_credentials_function has a new
3932 prototype, and its semantic has changed. You need to rewrite the
3933 callback, see the updated function documentation and SRP example code
3934 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
3937 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
3938 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
3939 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
3940 used. There are #define's to map the old names to the new. You may
3941 run into problems if you have a switch-case with cases for both SRP
3942 alerts, since they are now mapped to the same value. The solution is
3943 to drop the SRP alerts from such switch cases, as they are now
3944 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
3946 *** OpenPGP related changes
3947 The function `gnutls_certificate_set_openpgp_keyserver' have been
3948 removed. There is no replacement functionality inside GnuTLS. If you
3949 need keyserver functionality, consider using the GnuPG tools.
3951 All functions, types, and error codes related to OpenPGP trustdb
3952 format have been removed. The trustdb format is a non-standard
3953 GnuPG-specific format, and we recommend you to use key rings instead.
3954 The following have been removed:
3956 gnutls_certificate_set_openpgp_trustdb
3957 gnutls_openpgp_trustdb_init
3958 gnutls_openpgp_trustdb_deinit
3959 gnutls_openpgp_trustdb_import
3960 gnutls_openpgp_key_verify_trustdb
3961 gnutls_openpgp_trustdb_t
3962 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
3964 The following functions has an added parameter of the (new) type
3965 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
3966 (binary or base64). The functions are:
3967 gnutls_certificate_set_openpgp_key_file
3968 gnutls_certificate_set_openpgp_key_mem
3969 gnutls_certificate_set_openpgp_keyring_mem
3970 gnutls_certificate_set_openpgp_keyring_file
3972 To improve terminology and align with the X.509 interface, some
3973 functions have been renamed. Compatibility mappings exists. The old
3974 and new names of the affected functions and types are:
3977 gnutls_openpgp_key_t gnutls_openpgp_crt_t
3978 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
3979 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
3980 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
3981 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
3982 gnutls_openpgp_key_init gnutls_openpgp_crt_init

4064 * Version 2.1.6 (released 2007-11-15)
4066 ** Corrected bug in decompression of expanded compression data.
4068 ** Added the --to-p8 option to certtool to convert private keys
4071 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4073 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4076 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4077 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4078 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4079 documented. This caused some problems (e.g., debian #450854). To
4080 avoid backwards compatibility problems, this release revert this
4081 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4082 done in GnuTLS 2.0.x and earlier, and add a new error code
4083 GNUTLS_E_UNKNOWN_ALGORITHM.
4085 ** Fixes several gtk-doc warnings.
4087 ** API and ABI modifications:
4088 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4089 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4090 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4092 * Version 2.1.5 (released 2007-11-01)
4094 ** Fix PKCS#3 parameter export problem.
4096 ** Improve certtool queries, they now print the default value.
4100 ** Update gnulib files.
4102 ** API and ABI modifications:
4103 No changes since last version.
4105 * Version 2.1.4 (released 2007-10-27)
4107 ** Added the --v1 option to certtool, to allow generating X.509
4108 version 1 certificates.
4110 ** certtool: Add option --disable-quick-random to enable the old behaviour
4111 of using /dev/random to generate keys.
4113 ** Added priority functions that accept strings.
4115 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4116 priorities preferences.
4118 ** Added gnutls_record_disable_padding() to allow servers talking to
4119 buggy clients that complain if the TLS 1.0 record protocol padding is
4122 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4123 all supported compatibility options (like disabling padding).
4125 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4126 the format. This makes the interface consistent with the x509 functions.
4128 ** Internal copy of OpenCDK upgraded to version 0.6.5.

4167 * Version 2.1.3 (released 2007-10-17)
4169 ** TLS authorization support removed.
4170 This technique may be patented in the future, and it is not of crucial
4171 importance for the Internet community. After deliberation we have
4172 concluded that the best thing we can do in this situation is to
4173 encourage society not to adopt this technique. We have decided to
4174 lead the way with our own actions.

4191 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4192 gnutls_supplemental_data_format_type_t enum type becomes empty.
4194 * Version 2.1.2 (released 2007-10-14)
4196 ** Removed all the trustdb code from openpgp authentication.
4197 We now use only the well-specified keyrings.
4199 ** The 256 bit ciphers are not enabled in the default priorities.
4201 ** Added support for DSA2 using libgcrypt 1.3.0.

4236 * Version 2.1.1 (released 2007-09-24)
4238 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4239 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4240 compiled with Camellia support. See the libgcrypt documentation on
4241 how to enable it. Unconditionally disable it using the configure
4242 option --disable-camellia. Fixes #1.
4244 ** Properly document in the NEWS file the API change in the last release.
4246 ** API and ABI modifications:
4247 No changes since last version.
4249 * Version 2.1.0 (released 2007-09-20)
4251 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
4252 The support is disabled by default. Since no value has been allocated
4253 by the IANA for this extension yet, you will need to provide one
4254 yourself by invoking './configure --enable-opaque-prf-input=42'.
4257 ** Example code: Fix compilation flaw under MinGW.
4259 ** API and ABI modifications:
4260 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
4261 gnutls_oprfi_enable_client: ADD, new function.
4262 gnutls_oprfi_enable_server: ADD, new function.
4264 * Version 2.0.4 (released 2007-11-16)
4266 ** Corrected bug in decompression of expanded compression data.
4268 ** API and ABI modifications:
4269 No changes since last version.
4271 * Version 2.0.3 (released 2007-11-10)
4273 ** This version backports several fixes from the 2.1.x branch.
4275 ** Fixed PKCS #3 parameter export.
4277 ** Added gnutls_record_disable_padding() to allow servers talking to

4291 * Version 2.0.2 (released 2007-10-17)
4293 ** TLS authorization support removed.
4294 This technique may be patented in the future, and it is not of crucial
4295 importance for the Internet community. After deliberation we have
4296 concluded that the best thing we can do in this situation is to
4297 encourage society not to adopt this technique. We have decided to
4298 lead the way with our own actions.
4300 ** certtool: Fixed data corruption when using --outder.
4302 ** Fix configure-time Guile detection.
4304 ** API and ABI modifications:
4305 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4306 gnutls_supplemental_data_format_type_t enum type becomes empty.
4308 * Version 2.0.1 (released 2007-09-20)
4310 ** New directory doc/credentials/ with test credentials.
4311 This collects the test credentials from the web page and from src/.
4312 The script gnutls-http-serv has also been moved to that directory.
4314 ** Update SRP extension type and cipher suite with official IANA values.
4315 This breaks backwards compatibility with SRP in older versions of
4316 GnuTLS, but this is intentional to speed up the adoption of the
4317 official values. The old values we used were incorrect.
4319 ** Guile: Fix `x509-certificate-dn-oid'
4321 ** API and ABI modifications:
4322 No changes since last version.
4324 * Version 2.0.0 (released 2007-09-04)
4326 ** Included copy of Libtasn1 upgraded to version 1.1.
4328 ** Disable building of some examples if anonymous ciphers are disabled.
4330 ** Don't build examples for disabled features.
4332 ** API and ABI modifications:
4333 No changes since last version.
4335 * Version 1.7.19 (released 2007-08-27)
4337 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4338 This solves connection problems in mutt, see
4339 <http://bugs.debian.org/439640>.
4341 ** Update gnulib files.
4342 In particular, the getpass module -- with its dependencies on getline,
4343 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4344 library) directory to the gl/ directory (only used by the command line
4345 tools). The reason is that getpass is now only used by the
4346 command-line tools, and reducing the number of gnulib modules linked
4347 to the core library helps portability and reduces size.
4351 ** Disable building of PGP examples if PGP is disabled.
4353 ** Included copy of OpenCDK upgraded to version 0.6.4.
4355 ** API and ABI modifications:
4356 No changes since last version.
4358 * Version 1.7.18 (released 2007-08-16)
4360 ** Install images for the info manual.
4361 This has a side effect of renaming the images. See
4362 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4363 discussions on the approach chosen.
4365 ** Fix pointer mix to variables of different size.
4366 Patch extracted from
4367 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4369 ** Fix warnings during build.
4370 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4372 ** API and ABI modifications:
4373 No changes since last version.
4375 * Version 1.7.17 (released 2007-08-15)
4377 ** New functions to perform external signing.
4378 Set the signing callback function (of the gnutls_sign_func prototype)
4379 using the gnutls_sign_callback_set function. In the callback, you may
4380 find the new functions gnutls_x509_privkey_sign_hash and
4381 gnutls_openpgp_privkey_sign_hash useful. A new function
4382 gnutls_sign_callback_get is also added, to retrieve the function
4383 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4384 comments and testing.
4386 ** New self test of client and server authenticated X.509 TLS sessions.
4387 See tests/x509self.c and tests/x509signself.c. The latter also tests
4388 the new external signing callback interface.
4390 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4391 These two actually describe the outer limits of a range of error codes
4392 reserved to the application. All of the errors are treated as fatal
4393 by the library (it has to since it doesn't know the semantics of the
4394 error codes). This can be useful in callbacks, to signal some
4395 application-specific error condition, which will usually eventually
4396 cause some gnutls API to return the same error code as the callback,
4397 which then can be inspected by the application. Note that error codes
4400 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4401 The RFC is not released yet, and we're approaching a major release so
4402 let's not enable it just yet.
4404 ** Fix namespace so that gnutls_*_t is used consistently.
4405 Before, many places in the GnuTLS code used the old deprecated type
4406 names without the '_t' suffix.
4408 ** Build fixes for Guile code.
4409 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4411 ** More documentation fixes.
4412 In particular, the section headings were modified for casing. By
4413 Ludovic Courtes <ludovic.courtes@laas.fr>.
4415 ** Updated Polish and Swedish translations.
4416 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4417 <po@danielnylander.se>.
4419 ** API and ABI modifications:
4420 gnutls_sign_func: ADD, new type for sign callback.
4421 gnutls_sign_callback_set: ADD, new function to set sign callback.
4422 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4423 gnutls_x509_privkey_sign_hash,
4424 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4425 GNUTLS_E_APPLICATION_ERROR_MIN,
4426 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4428 * Version 1.7.16 (released 2007-08-07)
4430 ** Fix sanity checks and return values in certificate selection.
4431 In some cases, GnuTLS omitted to report suitable error codes when no
4432 suitable certificate was found.
4434 ** Fix gnutls-cli starttls EOF on Mac OS X.
4435 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4437 ** Documentation fixes.
4438 In particular, the section headings were modified for casing. By
4439 Ludovic Courtes <ludovic.courtes@laas.fr>.

4443 ** API and ABI modifications:
4444 No changes since last version.
4446 * Version 1.7.15 (released 2007-07-02)
4448 ** Fix self-tests key-id under mingw32.
4450 ** Test that the Guile header files are recent enough to work.
4451 Before we just tested that the command line tool 'guile' was recent
4452 enough, which may not be sufficient if you still have an old
4453 libguile.h header installed.
4455 ** Guile bindings are now installed under $prefix by default.
4456 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4457 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4458 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4459 The default, --with-guile-site-dir, will install the Guile bindings
4460 under $datadir/guile/site. There is a new section 'Guile
4461 Preparations' in the manual that discuss these issues.
4463 ** Fix run-time library path ordering in linking the Guile bindings.
4465 ** Improved manual on downloading, installing, getting help, bug reports etc.
4466 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4468 ** Add Malay message translations.

4516 * Version 1.7.12 (released 2007-06-08)
4518 ** Guile bindings for GnuTLS have been included.
4519 Contributed by Ludovic Courtès <ludovic.courtes@laas.fr>. There is a
4520 new chapter 'Guile Bindings' in the manual.
4522 ** Have PKCS8 parser return better error codes.

4528 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4529 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4532 Reported by Dennis Vshivkov <walrus@amur.ru>, see
4533 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=333050>. Added
4534 self-test tests/parse_ca.c to test regressions.
4536 ** Fix build failures related to missing images in manual.
4537 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.

4546 ** Include opencdk.h in the release.
4547 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4549 ** API and ABI modifications:
4550 No changes since last version.
4552 * Version 1.7.10 (released 2007-05-25)
4554 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4555 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4557 ** Update of gnulib files.
4559 ** GnuTLS is now developed in GIT instead of CVS.
4560 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4562 ** API and ABI modifications:
4563 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4564 gnutls_x509_crt_get_raw_dn: ADD.
4566 * Version 1.7.9 (released 2007-05-12)
4568 ** X.509 certificates are preferred over OpenPGP keys.
4569 This is a change in the semantics of gnutls_set_default_priority.
4571 ** The included copy of OpenCDK has been updated to 0.6.1.
4572 There has been some API changes in OpenCDK, and the GnuTLS layer have
4573 been modified as well. Note that while there are API/ABI incompatible
4574 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4575 its API/ABI have not changed. From this version on, GnuTLS requires
4576 OpenCDK 0.6.0 or later.
4578 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4580 ** Change certtool's default serial number from 0 to a time-based value.
4582 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4583 Before, we remove the parameters field, which resulted in a slightly
4584 different DER encoding which in turn caused signature verification
4585 failures of GnuTLS-generated RSA certificates in some other
4586 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4587 you read, this may or may not be correct, but our new behaviour appear
4588 to be consistent with other widely used implementations.
4590 ** Fix mem leaks in gnutls_x509_crt_print.
4592 ** API and ABI modifications:
4593 No changes since last version.
4595 * Version 1.7.8 (released 2007-04-16)
4597 ** Added examples for the authorization extension.
4598 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4600 ** The examples only use gnutls_set_default_priority().
4601 The exception is when DH_ANON is needed.
4603 ** Improve gnutls_set_default_priority() priorities.
4604 The new approach is for it to try and negotiate all secure and
4605 standard mechanisms available. Currently, DH_ANON ciphersuites and
4606 LZO compressions are not enabled by default, because they are,
4607 respectively, insecure and non-standardized. Note that TLS 1.2 will
4608 not be enabled by default in non-experimental release until it has
4609 been approved by the IETF.
4611 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4612 This means that to get DH_ANON and LZO compression, you'll need to
4613 specify that manually using '--kx anon' or '--comp lzo'.
4615 ** Minor fixes to the human display format of X.509 certificates.
4617 ** New APIs to extract Distinguished Name's from X.509 certificates.
4618 Based on patch from Howard Chu <hyc@symas.com>.
4620 ** Improved library searching for opencdk.
4621 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4622 The deprecated opencdk.m4 is no longer used.
4624 ** New APIs to list supported algorithms in the library.
4625 The APIs are gnutls_cipher_list, gnutls_mac_list,
4626 gnutls_compression_list, gnutls_protocol_list,
4627 gnutls_certificate_type_list, gnutls_kx_list, and
4628 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4630 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4632 ** New configure option --disable-tls-authorization to disable tls-authz.
4634 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4635 The last parameter was renamed from 'flags' to 'format' and the type
4636 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4637 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4640 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4641 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4643 ** API and ABI modifications:
4644 gnutls_x509_dn_t: ADD.
4645 gnutls_x509_ava_st: ADD.
4646 gnutls_x509_crt_get_subject,
4647 gnutls_x509_crt_get_issuer: ADD.
4648 gnutls_x509_dn_get_rdn_ava: ADD.
4649 gnutls_cipher_list: ADD.
4650 gnutls_mac_list: ADD.
4651 gnutls_compression_list: ADD.
4652 gnutls_protocol_list: ADD.
4653 gnutls_certificate_type_list: ADD.
4654 gnutls_kx_list: ADD.
4655 gnutls_cipher_suite_info: ADD.
4657 * Version 1.7.7 (released 2007-02-22)
4659 ** Support for supplemental handshake messages and authorization data.
4660 Supplemental data is described in RFC 4680 and the authorization
4661 extensions in draft-housley-tls-authz-extns-07.
4663 ** Support for authorization data in gnutls-cli and gnutls-serv.
4664 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4666 ** Fix for gnutls_x509_crt_check_hostname.
4667 Before it would have reported that the certificate matched a hostname
4668 when it did not have any dNSName or any CN field. Report and tiny
4669 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4671 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
4672 Tests regressions of the bug, and several other features.
4674 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
4675 Before there were no support for iPAddress SAN's during comparison.
4677 ** New API to print information about CRL's.
4678 The function is gnutls_x509_crl_print.
4680 ** New API to extract signature value from CRL's.
4681 The function is gnutls_x509_crl_get_signature.
4683 ** Support for directoryName Subject Alternative Name's.
4684 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
4685 string in the provided buffer.
4687 ** Internal improvements to certtool.
4688 It uses gnutls_x509_crl_print to print CRL information. It uses some
4689 more gnulib modules to simplify error handling.
4691 ** API and ABI modifications:
4692 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
4693 gnutls_supplemental_data_format_type_t: ADD.
4694 gnutls_authz_data_format_type_t: ADD.
4695 gnutls_supplemental_get_name: ADD.
4696 gnutls_authz_recv_callback_func,
4697 gnutls_authz_send_callback_func: ADD, callback prototypes.
4698 gnutls_authz_enable: ADD.
4699 gnutls_authz_send_x509_attr_cert,
4700 gnutls_authz_send_saml_assertion,
4701 gnutls_authz_send_x509_attr_cert_url,
4702 gnutls_authz_send_saml_assertion_url: ADD.
4703 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
4704 gnutls_x509_crl_print: ADD.
4705 gnutls_x509_crl_get_signature: ADD.
4707 * Version 1.7.6 (released 2007-02-12)
4709 ** Support for 'otherName' Subject Alternative Names.
4710 The existing API gnutls_x509_crt_get_subject_alt_name may now return
4711 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
4712 To find out the otherName OID (necessary for proper parsing of the
4713 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
4714 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
4715 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
4716 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
4718 ** Certtool can print otherName SAN values for certificates.
4719 For known otherName OIDs (currently only id-on-xmppAddr as defined by
4720 RFC 3920), it will also print the name.
4722 ** Fix TLS 1.2 RSA signing in servers.
4723 Before it used the old-style MD5+SHA1 signature, but the TLS
4724 signatures should be normal PKCS#1 signatures. FYI, we use and
4725 require that DigestInfo parameters are present and NULL for TLS 1.2.
4727 ** Add APIs to access X.509 extensions sequentially.
4728 The existing APIs gnutls_x509_crt_get_extension_oid() and
4729 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
4730 inspect the extensions in the order defined by the certificate.
4732 ** Add API to extract signature value from X.509 certificates.
4733 The function is gnutls_x509_crt_get_signature.
4735 ** Fix crash when generating proxy certificates in batch mode.
4736 If you don't specify a proxy policy in batch mode, it will use
4739 ** Add API to print information about X.509 certificates.
4740 The function is gnutls_x509_crt_print.
4742 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
4743 One consequence of this is that the output syntax has changed
4744 slightly. Some more fields are printed.
4748 ** API and ABI modifications:
4749 gnutls_x509_crt_print: ADD
4750 gnutls_certificate_print_formats_t: ADD, new enum.
4751 gnutls_x509_crt_get_signature: ADD.
4752 gnutls_x509_crt_get_extension_data: ADD.
4753 gnutls_x509_crt_get_extension_info: ADD.
4754 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
4755 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
4756 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
4758 * Version 1.7.5 (released 2007-02-06)
4760 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
4763 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
4765 ** Fix --list output for gnutls-cli and gnutls-serv.
4766 Mention TLS1.2, SHA512 etc.
4768 ** Manual contains new section on setting up a test HTTP server.
4769 A server set up following those descriptions are available online via
4770 <http://www.gnutls.org/server.html>.
4772 ** Update of gnulib files.
4774 ** API and ABI modifications:
4775 No changes since last version.
4777 * Version 1.7.4 (released 2007-02-05)
4779 ** Support for RSA signing using SHA-256/384/512.
4780 A new self test "sha2" tries to build a long X.509 certificate chain
4781 testing all new hashes.
4783 ** The gnutls-serv tool now use static DH parameters if none are supplied.
4785 ** Discuss proxy certificates in the manual.
4787 ** Improve bibliographical citations in the manual.
4789 ** Update of gnulib files.
4791 ** Fix certtool template handling of pathLenConstraints.
4792 It now defaults to -1 instead of 0, which causes the field to be
4793 missing unless the template specify it.
4795 ** API and ABI modifications:
4798 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
4801 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
4802 GNUTLS_SIGN_RSA_SHA256,
4803 GNUTLS_SIGN_RSA_SHA384,
4804 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
4806 * Version 1.7.3 (released 2007-02-01)
4808 ** New option to certtool: --generate-proxy.
4809 This will generate a Proxy Certificate from an end entity certificate.
4810 Proxy Certificates are documented in RFC 3820. You will need to
4811 specify the proxy certificate's private key with --load-privkey, the
4812 user certificate with --load-certificate and the private key used to
4813 sign the new proxy certificate with --load-ca-privkey. Certtool will
4814 query for proxy path length and the policy language OID. Currently
4815 only OIDs that have an empty policy are supported (which includes the
4816 two OIDs defined by RFC 3820).
4818 ** Certtool --certificate-info now prints information for Proxy Certificates.
4819 Before the proxy extension was just printed as DER encoded data.
4821 ** New APIs to set proxy subject names and get/set proxy cert extension.
4823 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
4825 ** Added self-test to test for regressions of pathLenConstraint bug.
4826 Incidentally, this also test (some) other regressions or changes in
4827 the output from certtool --certificate-info.
4829 ** When certtool generates CA certificates, pressing enter on the path
4830 ** length constraint query will now remove the field.
4831 Before it set the path length constraint to 0, which is a rather poor
4834 ** Certtool now print times in UTC when printing certificate/CRL info.
4836 ** Add better fix to work around C++ compiler bug on Mac OS X.
4837 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
4839 ** Fix import of ASCII armored OpenPGP keys.
4840 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
4842 ** Update of gnulib files.
4844 ** API and ABI modifications:
4845 gnutls_x509_crt_set_proxy_dn: ADD.
4846 gnutls_x509_crt_set_proxy: ADD.
4847 gnutls_x509_crt_get_proxy: ADD.
4849 * Version 1.7.2 (released 2007-01-14)
4851 ** Certtool now print the value of the pathLenConstraints field for certs.
4853 ** Certtool now query for path length constraints when generating CA certs.
4854 For batch uses, the certtool configuration name is "path_len".
4855 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
4857 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
4858 The new functions gnutls_x509_crt_get_basic_constraints and
4859 gnutls_x509_crt_set_basic_constraints provide a superset of the
4860 functionality in the old gnutls_x509_crt_get_ca_status and
4861 gnutls_x509_crt_set_ca_status (respectively), but the old functions
4862 will continue to be supported.
4864 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
4865 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
4866 OpenCDK release with this patch will be made soon, which should bump
4867 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
4869 ** Certtool --to-p12 can now store more than one certificate in the blob.
4870 Before it could only store one certificate, but now it will read and
4871 store as many certificate there are from the --load-certificate file.
4872 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
4874 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
4875 In particular, the OpenPGP function variables are no longer part of
4876 the exported libgnutls interface, and no header files from
4877 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
4878 were never intended for non-internal purposes, and thus this does not
4879 imply a change in the external API/ABI.
4881 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
4882 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4884 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
4885 Before these parameters were set to make GnuTLS build under mingw32,
4886 however, they appear to no longer be necessary.
4888 ** A minor fix to the C++ library to make it build.
4889 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
4891 ** Update of gnulib files.
4893 ** API and ABI modifications:
4894 gnutls_x509_crt_get_basic_constraints: ADD.
4895 gnutls_x509_crt_set_basic_constraints: ADD.
4896 cdk_pubkey_to_sexp: ADD (in opencdk).
4897 cdk_seckey_to_sexp: ADD (in opencdk).
4899 * Version 1.7.1 (released 2006-12-28)
4901 ** TLS 1.2 server side fix.
4902 The Certificate Request sent did not contain the list of supported
4903 hashes field, thus violating the protocol. It will now contain an
4904 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4906 ** TLS 1.2 DSA signature verification fix.
4907 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4909 ** Fix the list of trusted CAs that server's send to clients.
4910 Before, the list contained issuer DN's instead of subject DN's of the
4911 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
4913 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
4914 Also added a self-test in tests/certificate_set_x509_crl.c to test the
4915 function. Reported by Max Kellermann <max@duempel.org>.
4917 ** Encode UID fields in DN's as DirectoryString.
4918 Before GnuTLS encoded and parsed UID fields as IA5String. This was
4919 incorrect, it should have used DirectoryString. Now it will use
4920 DirectoryString for the UID field, but for backwards compatibility it
4921 will also accept IA5String UID's. Reported by Max Kellermann
4924 ** Improve out-of-sourcedir builds from CVS.
4925 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
4927 ** Bootstrap tools changed.
4928 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
4929 building GnuTLS from CVS. Libtool 1.5.22 is used.
4931 ** Fixed a syntax error in lib/gnutls.asn.
4932 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
4934 ** Added German translation of GnuTLS messages.
4936 ** Update of gnulib files.
4938 ** API and ABI modifications:
4939 No changes since last version.
4941 * Version 1.7.0 (released 2006-11-29)
4943 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
4944 The details is that the protocol priority set by
4945 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
4946 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
4948 ** Preliminary support for TLS 1.2.
4949 The client has been successfully tested against
4950 https://www.mikestoolbox.org:4433/.
4952 ** Anonself test now print a lot of debugging info, including TLS version.
4954 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
4956 ** Update of gnulib files.
4958 ** API and ABI modifications:
4959 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
4961 *** Pulled up from stable 1.6.x branch:
4963 ** Fix ./configure failure with non-GCC compilers.
4964 This fixes the following error message:
4965 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
4966 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
4968 * Version 1.6.3 (released 2007-05-26)
4970 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4971 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
4972 from the 1.7.x branch, see
4973 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
4975 ** Have PKCS8 parser return better error codes.
4976 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
4977 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
4978 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
4980 ** Fix mem leak for sessions with client authentication via certificates.
4981 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
4982 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
4984 ** Fix building of 'tlsia' self test.
4985 Earlier some gcc are known to build tlsia linking to
4986 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
4987 the build directory, even though command line parameters look OK.
4988 Changing order of some parameters fixes it.
4990 ** API and ABI modifications:
4991 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4992 gnutls_x509_crt_get_raw_dn: ADD.
4994 * Version 1.6.2 (released 2007-04-18)
4996 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4997 Before, we remove the parameters field, which resulted in a slightly
4998 different DER encoding which in turn caused signature verification
4999 failures of GnuTLS-generated RSA certificates in some other
5000 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5001 you read, this may or may not be correct, but our new behaviour appear
5002 to be consistent with other widely used implementations.
5004 ** Regenerate the PKIX ASN.1 syntax tree.
5005 For some reason, after changing the ASN.1 type of ldap-UID in the last
5006 release, the generated C file built from the ASN.1 schema was not
5007 refreshed. This can cause problems when reading/writing UID
5008 components inside X.500 Distinguished Names. Reported by devel
5009 <dev001@pas-world.com>.
5011 ** Updated translations.
5013 ** API and ABI modifications:
5014 No changes since last version.
5016 * Version 1.6.1 (released 2006-12-28)
5018 ** Fix the list of trusted CAs that server's send to clients.
5019 Before, the list contained issuer DN's instead of subject DN's of the
5020 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5022 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5023 Reported by Max Kellermann <max@duempel.org>.
5025 ** Encode UID fields in DN's as DirectoryString.
5026 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5027 incorrect, it should have used DirectoryString. Now it will use
5028 DirectoryString for the UID field, but for backwards compatibility it
5029 will also accept IA5String UID's. Reported by Max Kellermann
5032 ** Fix ./configure failure with non-GCC compilers.
5033 This fixes the following error message:
5034 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5035 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5037 ** API and ABI modifications:
5038 No changes since last version.
5040 * Version 1.6.0 (released 2006-11-17)
5042 ** No changes since 1.5.5.
5043 The major changes compared to the 1.4.x branch are:
5045 *** A GnuTLS C++ library is part of the official distribution.
5046 Currently there are no examples or documentation, but hopefully this
5047 will change. See gnutlsxx.h for the API.
5049 *** Windows is a supported platform.
5050 There are, however, two know bugs. One is related to select() in
5051 command line tools (not, nota bene, in the library), the other is a
5052 problem with libgcrypt that causes delays. Help is needed to resolve
5053 those issues, so we feel we can't delay the release because of this.
5055 *** New APIs for custom push/pull function error reporting.
5056 The new APIs are gnutls_transport_set_errno and
5057 gnutls_transport_set_global_errno. See the release notes for version
5058 1.5.4 for more information.
5060 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5062 * Version 1.5.5 (released 2006-11-16)
5064 ** Correctly bump shared library version after adding new APIs.
5065 This was forgotten in the last release.
5067 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5068 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5070 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5072 ** Update of gnulib files.
5074 ** API and ABI modifications:
5075 No changes since last version.
5077 * Version 1.5.4 (released 2006-11-07)
5079 ** New API functions to set errno in push/pull functions.
5080 Under Windows, setting the errno variable in a push/pull replacement
5081 may end up setting the wrong errno variable, and GnuTLS send/recv
5082 functions become confused about the real errno returned from a failed
5083 push/pull function. Therefor, we have added two APIs to set the errno
5084 variable used by GnuTLS. The APIs can also help to keep things
5085 thread-safe, by avoiding potentially global variables. Typically,
5086 instead of setting errno in your push/pull function, you will call one
5087 of these functions. It is recommended to use
5088 gnutls_transport_set_errno, but if you don't have the session variable
5089 easily accessible in the push/pull replacement function, you can use
5090 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5091 <tim.kosse@filezilla-project.org>.
5093 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5094 void gnutls_transport_set_global_errno (int err);
5096 ** When calling `recv' or `send' Windows errors are handled properly.
5097 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5098 WSAGetLastError to access the error condition instead.
5100 ** Several OpenPGP API fixes.
5101 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5102 important fix is to change the return value of
5103 gnutls_openpgp_privkey_get_pk_algorithm and
5104 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5105 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5106 compatible with 'int').
5108 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5109 ** version, try to negotiate the highest version support by the GnuTLS server,
5110 ** instead of the lowest.
5111 Reported by <Pasi.Eronen@nokia.com>.
5113 ** Replace old constructs with use of gnulib modules.
5114 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5115 the code. If the headers doesn't exist on the target system, gnulib
5116 will make sure its replacement header files are used instead.
5118 ** Fix SOVERSION computation for *.def files.
5119 This fixes build errors similar to "No rule to make target
5120 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5122 ** gnutls_check-version uses strverscmp from gnulib.
5124 ** Update of gnulib files.
5126 ** API and ABI modifications:
5127 gnutls_transport_set_errno: ADD
5128 gnutls_transport_set_global_errno: ADD
5130 * Version 1.5.3 (released 2006-10-26)
5132 ** Add new self-test of RSA-MD5 signature chains.
5133 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5134 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5135 and is based on the work by Marc Stevens et al, see
5136 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5138 ** Re-factor self tests.
5140 ** The include copy of Libtasn1 is updated to version 0.3.7.
5142 ** The included copy of OpenCDK is updated to version 0.5.11.
5144 ** Fix the filename of the *.def file on Windows after library version bump.
5146 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5147 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5148 gnulib modules. Earlier we could only use the LGPL'ed module from
5149 gnulib, because two gnulib directories in the same project didn't
5152 ** API and ABI modifications:
5153 No changes since last version.
5155 * Version 1.5.2 (released 2006-10-03)
5157 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5158 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5159 shared library version than this version, so you'll have to remove
5160 them and possibly relink your applications. The reason for this is
5161 that no API/ABI changes have been made since the 1.4.x branch, and
5162 that incrementing the shared library version was a mistake. Reported
5163 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5165 ** Fix off-by-one error when computing length to malloc.
5166 The code is used by gnutls_openpgp_add_keyring_file and
5167 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5168 <agl@imperialviolet.org>.
5170 ** Add version script for the GnuTLS C++ library.
5171 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5173 ** Fix the C++ compiler detection logic.
5174 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5176 ** Update of gnulib files.
5178 ** API and ABI modifications:
5179 No changes since last version.
5181 * Version 1.5.1 (released 2006-09-21)
5183 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5184 ** Crypto 06 rump session attack.
5185 In particular, we check that the digestAlgorithm.parameters field is
5186 missing or empty, to avoid that it can contain "garbage" that may be
5187 used to alter the numeric properties of the signature. See
5188 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5189 not exactly the same as the problem we fix here). Reported by Yutaka
5190 OIWA <y.oiwa@aist.go.jp>.
5192 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5193 up to date information.
5195 ** Add self test to test for above flaw.
5197 ** Fix gnutls-cli-debug regarding resume support detection.
5198 Earlier, if the session-id from the server had a length of 0, it would
5199 indicate that the server supports resumption, which isn't the case.
5200 Reported by Kataja Kai <kai.kataja@op.fi>.
5202 ** Fix building of examples on FreeBSD by including netinet/in.h.
5203 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5205 ** Fix certtool bug that caused the private key to not be loaded when
5206 generating a certificate with --load-request, which in turn triggered
5207 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5208 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5210 ** gnutls-cli and gnutls-serv works on Windows.
5211 The problem was the select() call that doesn't work on file
5212 descriptors (stdin) on Windows. We borrowed some code from plibc to
5213 solve this. It appears to be somewhat unreliable though.
5215 ** Autoconf 2.60 is now used.
5217 ** API and ABI modifications:
5218 No changes since last version.
5220 * Version 1.5.0 (released 2006-08-13)
5222 ** Change SRP and Cert-Type extensions to match IANA registry.
5224 ** Fixed bug in OpenPGP authentication handshake.
5226 ** Improvements for building under MinGW.
5227 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5228 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5229 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5230 at run-time from ws2_32.dll, and falls back on a simple replacement if
5231 it is not available. Builds the library with -mms-bitfields
5232 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5233 create *.def files, which are installed.
5235 ** The examples now (conditionally) include config.h and link to gnulib.
5236 No other source changes were necessary, so the examples should
5237 continue to be possible to use stand-alone without any autoconf or
5240 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5241 You may unconditionally disable it with --disable-cxx. See
5242 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5245 ** Made command line tool '--version' behave according to GNU Standards.
5246 This enables 'make distcheck' to succeed.
5248 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5250 ** Make --without-included-libtasn1 work.
5251 Reported by Daniel Black <dragonheart@gentoo.org>.
5253 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.

5276 ** Relax the test that caught signatures that exploit the variant of
5277 ** Bleichenbacher's Crypto 06 rump session attack on our
5278 ** verification logic flaw.
5279 In particular, we now permit the digestAlgorithm.parameters field to
5280 be present but empty, whereas in 1.4.3 we actually checked that the
5283 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5284 The messages are only printed in debug mode, which is not recommended
5285 for normal use, and thus logging this situation cannot be abused as an
5286 oracle in typical recommended situations.
5288 ** API and ABI modifications:
5289 No changes since last version.
5291 * Version 1.4.3 (released 2006-09-08)
5293 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5294 ** Crypto 06 rump session attack.
5295 In particular, we check that the digestAlgorithm.parameters field is
5296 empty, to avoid that it can contain "garbage" that may be used to

5317 * Version 1.4.2 (released 2006-08-12)
5319 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5320 This can happen if you call gnutls_certificate_verify_peers2 and have
5321 a certain mix of local CA certificates and the peer send special
5322 certificates, that together trigger certain behaviour. It is not
5323 known at this point whether the crash can be triggered without the
5324 special local CA certificate, and thus turn this into a remote crash
5325 of clients that verify server certificates when they talk to a server
5326 with the special server certificate. See GNUTLS-SA-2006-2 on
5327 http://www.gnu.org/software/gnutls/security.html for more up to date
5328 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5330 ** Change SRP and Cert-Type extensions to match IANA registry.
5332 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5334 ** Make --without-included-libtasn1 work.
5335 Reported by Daniel Black <dragonheart@gentoo.org>.
5337 ** API and ABI modifications:
5338 No changes since last version.
5340 * Version 1.4.1 (released 2006-06-14)
5342 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5344 ** Fixed bug in OpenPGP authentication handshake.
5346 ** Fixed typographical in man pages.
5348 ** Build fixes of the manual.
5350 ** Added Swedish translation.
5352 ** API and ABI modifications:
5353 No changes since last version.
5355 * Version 1.4.0 (released 2006-05-15)
5357 ** Remove GnuTLS 0.8.x compatibility functions.
5359 ** The libgcrypt RNG is initialized in gnutls_global_init().
5361 ** TLS/IA API changes from Emile van Bergen.
5362 A dummy credential structure is not needed now, if you wish to use the
5363 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5366 ** The self-tests are now run under valgrind, if it is installed.
5368 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5370 ** The command line tools now use getaddrinfo and support IPv6.
5372 ** API and ABI modifications:
5373 _gnutls_x509_get_raw_crt_activation_time,
5374 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5375 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5376 gnutls_ia_enable: Added.
5378 * Version 1.3.5 (released 2006-03-08)
5380 ** Error messages are now translated using GNU Gettext.
5382 ** The function gnutls_x509_crt_to_xml now return an internal error.
5383 This means that the code to convert X.509 certificates to XML format
5384 does not work any more. The reason is that the function called
5385 libtasn1 internal functions. It seems unclean for libtasn1 to export
5386 the APIs needed here. Instead it would be better to implement XML
5387 support inside libtasn1 properly. If you need this functionality
5388 strongly, please consider looking into implementing this suggested
5389 approach instead. As a workaround, you may also modify lib/x509/xml.c
5390 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5392 ** Libraries are now built with libtool's -no-undefined.
5393 This helps producing libraries for Windows using mingw32.
5395 ** Doc fixes to explain that gnutls_record_send can block.
5397 ** Libtasn1 0.3.1 or later is now required.
5398 The include copy has been updated too.
5400 ** gnutls-cli can now recognize services and port numbers with the -p option.
5402 ** API and ABI modifications:
5403 No changes since last version.
5405 * Version 1.3.4 (released 2006-02-09)
5407 ** Fix read of out bounds bug in DER parser.
5408 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5409 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5410 previous bug fix. The included libtasn1 version in GnuTLS has been
5413 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5414 longer invalidate a session if the underlying send fails, but it will
5415 prevent future writes. That is to allow reading the already received data.
5416 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5418 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5419 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5420 more than one certificates were added. Report and patch by Max Kellermann.
5422 ** Fix build problems of OpenCDK on AIX.
5423 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5425 ** API and ABI modifications:
5426 No changes since last version.
5428 * Version 1.3.3 (released 2006-01-12)
5430 ** New API to access the TLS master secret.
5431 When possible, you should use the TLS PRF functions instead.
5432 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5434 ** Improved handling when multiple libraries use GnuTLS at the same time.
5435 Now gnutls_global_init() can be called multiple times, and
5436 gnutls_global_deinit() will only deallocate the structure when it has
5437 been called as many times as gnutls_global_init() was called.
5439 ** Added a self test of TLS resume functionality.
5441 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5443 ** Documentation fixes about thread unsafety, prompted by
5444 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5445 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5446 thread safe. Careful callers may want to protect the call using a
5447 mutex. The problem could also be ignored, which would cause a memory
5448 leak under rare conditions when two threads invoke the function
5449 roughly at the same time.
5451 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5453 ** The code was indented again, including the external header files.
5455 ** API and ABI modifications:
5456 New functions to retrieve the master secret value:
5457 gnutls_session_get_master_secret
5459 Add a 'const' keyword to existing API:
5460 gnutls_x509_crq_get_challenge_password
5462 * Version 1.3.2 (released 2005-12-15)
5464 ** GnuTLS now support TLS Inner application (TLS/IA).
5465 This is per draft-funk-tls-inner-application-extension-01. This
5466 functionality is added to libgnutls-extra, so it is licensed under the
5467 GNU General Public License.
5469 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5470 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5471 and EAP-TTLS. One function to access the raw PRF and one to access
5472 the PRF seeded with the client/server random fields are provided.
5473 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5475 ** New APIs to acceess the client and server random fields in a session.
5476 These fields can be useful by protocols using TLS. Note that these
5477 fields are typically used as input to the TLS PRF, and if this is your
5478 intended use, you should use the TLS PRF API that use the
5479 client/server random field directly. Suggested by Jouni Malinen
5480 <jkmaline@cc.hut.fi>.
5482 ** Internal type cleanups.
5483 The uint8, uint16, uint32 types have been replaced by uint8_t,
5484 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5485 correct types on platforms that lack them. The uint type have been
5486 replaced by unsigned.
5488 ** API and ABI modifications:
5489 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5493 New functions to retrieve the session's client and server random values:
5494 gnutls_session_get_server_random
5495 gnutls_session_get_client_random
5497 New function, to perform TLS/IA handshake:
5500 New function to decide whether to do a TLS/IA handshake:

5503 New functions to allocate a TLS/IA credential:
5504 gnutls_ia_allocate_client_credentials
5505 gnutls_ia_free_client_credentials
5506 gnutls_ia_allocate_server_credentials
5507 gnutls_ia_free_server_credentials

5514 gnutls_ia_set_server_avp_ptr
5515 gnutls_ia_get_server_avp_ptr
5517 New functions, to toggle TLS/IA application phases:
5518 gnutls_ia_require_inner_phase
5520 New function to mix session keys with inner secret:
5521 gnutls_ia_permute_inner_secret
5523 Low-level API (used internally by gnutls_ia_handshake):
5524 gnutls_ia_endphase_send
5528 New functions that can be used after successful TLS/IA negotiation:
5529 gnutls_ia_generate_challenge
5530 gnutls_ia_extract_inner_secret
5532 Enum type with TLS/IA modes:
5535 Enum type with TLS/IA packet types:
5538 Enum values for TLS/IA alerts:
5539 GNUTLS_A_INNER_APPLICATION_FAILURE
5540 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5542 New error codes, to signal when an application phase has finished:
5543 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5544 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5546 New error code to signal TLS/IA verify failure:
5547 GNUTLS_E_IA_VERIFY_FAILED
5549 * Version 1.3.1 (released 2005-12-08)
5551 ** Support for DHE-PSK cipher suites has been added.
5552 This method offers perfect forward secrecy.
5554 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5555 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5557 ** Corrected a bug in certtool for 64 bit machines. Reported
5558 by Max Kellermann <max@duempel.org>.
5560 ** New function to set a X.509 private key and certificate pairs, and/or
5561 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5562 <emile@e-advies.nl>.
5564 The integrity of the PKCS#12 file is protected through a password
5565 based MAC; public-key based signatures for integrity protection are
5566 not supported. PKCS#12 bags may be encrypted using password derived
5567 symmetric keys, public-key based encryption is not supported. The
5568 PKCS#8 keys may be encrypted using passwords. The API use the same
5569 password for all operations. We believe that any more flexibility
5570 create too much complexity that would hurt overall security, but may
5571 add more PKCS#12 related APIs if real-world experience indicate
5574 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5575 reported by Emile van Bergen <emile@e-advies.nl>.
5576 This will enable "certtool -k -8" to parse those keys.
5578 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5579 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5580 certtool would have encrypted the key using an empty password.
5582 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5583 Earlier it would have prompted the user for it, even if --password was
5586 ** Added self test of PKCS#8 parsing.
5587 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5588 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5591 ** API and ABI modifications:
5592 New function to set X.509 credentials from a PKCS#12 file:
5593 gnutls_certificate_set_x509_simple_pkcs12_file
5595 New gnutls_kx_algorithm_t enum type:
5598 New API to return session data (basically same as gnutls_session_get_data):
5599 gnutls_session_get_data2
5601 New API to set PSK Diffie-Hellman parameters:
5602 gnutls_psk_set_server_dh_params
5604 * Version 1.3.0 (2005-11-15)
5606 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5607 This add several new APIs, see below. Read the updated manual for
5608 more information. A new self test "pskself" has been added, that will
5609 test this functionality.
5611 ** The session resumption data are now system independent.
5613 ** The code has been re-indented to conform to the GNU coding style.
5615 ** Removed the RIPEMD ciphersuites.
5617 ** Added a discussion of the internals of gnutls in manual.
5619 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5621 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5623 ** Make sure config.h is included first in a few files, from Albert Chin.

5633 New gnutls_credentials_type_t credential type:
5636 New credential types:
5637 gnutls_psk_server_credentials_t

5670 * Version 1.2.11 (2006-05-11)
5671 - The function gnutls_x509_crt_to_xml is not supported any more, and
5672 return an internal error. The reason is that the function called
5673 internal libtasn1 functions which are no longer exported from
5675 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
5676 - Updated gnulib compatibility files.
5677 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
5678 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
5679 - API and ABI modifications:
5680 No changes since last version.
5682 * Version 1.2.10 (2006-02-09)
5683 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
5684 <admin@gleg.net>, and debugging help from Protover SSL.
5685 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
5686 The included version has been updated too.
5687 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5688 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5689 - Corrected a bug in certtool for 64 bit machines. Reported
5690 by Max Kellermann <max@duempel.org>.
5691 - Corrected bugs in gnutls_certificate_set_x509_crl() and
5692 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5693 more than one certificates were added. Report and patch by Max Kellermann.
5694 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5695 longer invalidate a session if the underlying send fails, but it will
5696 prevent future writes. That is to allow reading the already received data.
5697 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5699 * Version 1.2.9 (2005-11-07)
5700 - Documentation was updated and improved.
5701 - RSA-MD2 is now supported for verifying digital signatures.
5702 - Due to cryptographic advances, verifying untrusted X.509
5703 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
5704 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
5705 applications that must remain interoperable, you can use the
5706 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
5707 flags when verifying certificates. Naturally, this is not
5708 recommended default behaviour for applications. To enable the
5709 broken algorithms, call gnutls_certificate_set_verify_flags with the
5710 proper flag, to change the verification mode used by
5711 gnutls_certificate_verify_peers2.
5712 - Make it possible to send empty data through gnutls_record_send,
5713 to align with the send(2) API.
5714 - Some changes in the certificate receiving part of handshake to prevent
5715 some possible errors with non-blocking servers.
5716 - Added numeric version symbols to permit simple CPP-based feature
5717 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
5718 - The (experimental) low-level crypto alternative to libgcrypt used
5719 earlier (Nettle) has been replaced with crypto code from gnulib.
5720 This leads to easier re-use of these components in other projects,
5721 leading to more review and simpler maintenance. The new configure
5722 parameter --with-builtin-crypto replace the old --with-nettle, and
5723 must be used if you wish to enable this functionality. See README
5724 under "Experimental" for more information. Internally, GnuTLS has
5725 been updated to use the new "Generic Crypto" API in gl/gc.h. The
5726 API is similar to the old crypto/gc.h, because the gnulib code were
5727 based on GnuTLS's gc.h.
5728 - Fix compiler warning in the "anonself" self test.
5729 - API and ABI modifications:
5730 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
5731 This doesn't reflect a change in behaviour,
5732 so we don't break backwards compatibility.
5733 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
5734 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
5735 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
5736 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
5738 gnutls_x509_crt_list_verify,
5739 gnutls_x509_crt_verify, or
5740 gnutls_certificate_set_verify_flags.
5741 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
5742 used when broken signature algorithms
5743 is used (currently RSA-MD2/MD5).
5744 LIBGNUTLS_VERSION_MAJOR,
5745 LIBGNUTLS_VERSION_MINOR,
5746 LIBGNUTLS_VERSION_PATCH,
5747 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
5748 version number, can be used for feature existence
5751 * Version 1.2.8 (2005-10-07)
5752 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
5753 - Don't install the auxilliary libexamples library used by the
5754 examples in doc/examples/ on "make install", report and tiny patch
5755 from Thomas Klausner <tk@giga.or.at>.
5756 - If you pass a X.509 CA or PGP trust database to the command line
5757 tool, it will now abort the connection if the server certificate
5758 validation fails. Use the parameter --insecure to continue even
5759 after certificate validation failures. Inspired from discussion
5760 with Alexander Kotelnikov <sacha@myxomop.com>.
5761 - The test for socklen_t has been moved to gnulib.

5849 function prototypes during compile time.
5850 - API and ABI modifications:
5851 No changes since last version. At least not intentional, but due
5852 to the include header changes, there may be inadvertant changes,
5853 please let us know if you find any.

5860 - Added warning to certtool when MD5 is being used for digital
5862 - Optimizations ("-O2 -finline-functions") are not enabled by default,
5863 instead the standard autoconf defaults are used. Use `./configure
5864 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
5865 - Added the option --get-dh-params to certtool, in order to get the
5866 parameters included in the library primes and generators.

5902 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
5903 required, instead of the string length. That is, the value has been
5904 incremented by 1 to account for the terminating zero. Reported by
5905 Martin Lambers <marlam@web.de>.
5906 - Debug output shouldn't crash on platforms that doesn't handle NULL
