17 used by openconnect vpn client for compatibility with Cisco's AnyConnect
18 SSL VPN. It is marked as GNUTLS_DTLS0_9. Do not use it for newer protocols
19 as it has issues. Implemented by David Woodhouse.

270 under the gnutls_ocsp namespace. Currently the functionality provided
271 is to parse and extract information from OCSP requests/responses, to
272 generate OCSP requests and to verify OCSP responses. See the manual
273 for more information. Run ./configure with --disable-ocsp to build
274 GnuTLS without OCSP support.
276 This work was sponsored by Smoothwall <http://smoothwall.net/>.

399 allow listing the ciphersuites enabled in a priority structure.
400 It outputs an index to be used in gnutls_get_cipher_suite_info().
402 ** libgnutls: Optimizations in the elliptic curve code --timing
403 attacks resistant code is only used in ECDSA private key operations.
405 ** doc: man pages for API functions generation was fixed and are
406 now added again in the distribution.

621 ** libgnutls: gnutls_certificate_set_x509_key_file() and
622 friends support server name indication. If multiple
623 certificates are set using these functions the proper one
624 will be selected during a handshake.
626 ** libgnutls: Added AES-256-GCM which was left out from
627 the previous release. Reported by Benjamin Hof.
629 ** libgnutls: When asking for a PKCS# 11 PIN multiple
630 times, the flags in the callback were not being updated
631 to reflect for PIN low count or final try.
633 ** libgnutls: Do not allow second instances of PKCS #11
636 ** libgnutls: fixed alignment issue in AES-NI code.
638 ** libgnutls: The config file at gnutls_pkcs11_init()

697 not. (GNUTLS_PKCS11_OBJ_FLAG_MARK_PRIVATE and GNUTLS_PKCS11_OBJ_FLAG_MARK_NOT_PRIVATE)
699 ** libgnutls: Added SUITEB128 and SUITEB192 priority
700 strings to enable the NSA SuiteB cryptography ciphersuites.
702 ** libgnutls: Added gnutls_pubkey_verify_data2() that will
703 verify data provided the signature algorithm.
705 ** libgnutls: Simplified the handling of handshake messages to
706 be hashed. Instead of hashing during the handshake process we now
707 keep the data until handshake is over and hash them on request.
708 This uses more memory but eliminates issues with TLS 1.2 and
711 ** libgnutls: Added AES-GCM optimizations using the PCLMULQDQ
712 instruction. Uses Andy Polyakov's assembly code.
714 ** libgnutls: Added gnutls_x509_trust_list_add_named_crt() and
715 gnutls_x509_trust_list_verify_named_crt() that allow having a
716 list of certificates in the trusted list that will be associated
717 with a name (e.g. server name) and will not be used as CAs.
719 ** libgnutls: PKCS #11 back-end rewritten to use p11-kit
720 http://p11-glue.freedesktop.org/p11-kit.html. Rewrite by

1142 --p11-export-url, --p11-list-certs, --p11-list-certs,
1143 --p11-list-privkeys, --p11-list-trusted, --p11-list-all-certs,
1144 --p11-list-all, --p11-list-tokens, --p11-login, --p11-write,
1145 --p11-write-label, --p11-write-trusted, --p11-detailed-url,
1148 ** libgnutls: Corrected bug that caused importing DSA keys as RSA,
1149 introduced with the new nettle code.
1151 ** libgnutls: Corrected advertizing issue for session tickets.
1153 ** API and ABI modifications:
1154 gnutls_x509_crt_get_subject_unique_id: ADDED.
1155 gnutls_x509_crt_get_issuer_unique_id: ADDED.
1157 * Version 2.11.1 (released 2010-09-14)
1159 ** libgnutls: Nettle is the default crypto back end. Use --with-libgcrypt
1160 to use the libgcrypt back end.
1162 ** libgnutls: Depend on nettle 2.1. This makes nettle a fully working
1163 backend crypto library.
1165 ** libgnutls: Added RSA_NULL_SHA1 and SHA256 ciphersuites.
1167 ** libgnutls: Several updates in the buffering internal interface.
1169 ** libgnutls: Is now more liberal in the PEM decoding. That is spaces and
1170 tabs are being skipped.
1172 ** libgnutls: Added support for draft-pechanec-pkcs11uri-02.
1174 ** libgnutls: The %COMPAT flag now allows larger records that violate the
1177 ** libgnutls: by default lowat level has been set to zero to avoid unnecessary
1178 system calls. Applications that depended on it being 1 should explicitly call
1179 gnutls_transport_set_lowat().
1181 ** libgnutls: Updated documentation and gnutls_pk_params_t mappings
1182 to ECRYPT II recommendations. Mappings were moved to a single location
1183 and DSA keys are handled differently (since DSA2 allows for 1024,2048
1184 and 3072 keys only).
1186 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1187 gnutls_x509_privkey_import_pkcs8() without a password, if it
1188 is unable to decode the key.
1190 ** libgnutls: HMAC-MD5 no longer used by default.
1192 ** API and ABI modifications:
1193 gnutls_openpgp_privkey_sec_param: ADDED
1194 gnutls_x509_privkey_sec_param: ADDED
1196 * Version 2.11.0 (released 2010-07-22)
1198 ** libgnutls: support scattered write using writev(). This takes
1199 advantage of the new buffering layer and allows queuing of packets
1200 and flushing them. This is currently used for handshake messages
1203 ** libgnutls: Added gnutls_global_set_mutex() to allow setting
1204 alternative locking procedures. By default the system available
1205 locking is used. In *NIX pthreads are used and in windows the
1206 critical section API. This follows a different approach than the
1207 previous versions that depended on libgcrypt initialization. The
1208 locks are now set by default in systems that support it. Programs
1209 that used gcry_control() to set thread locks should insert it into
1211 #if GNUTLS_VERSION_NUMBER <= 0x020b00
1215 ** libgnutls: Added support for reading DN from EV-certificates.
1217 jurisdictionOfIncorporationLocalityName,
1218 jurisdictionOfIncorporationStateOrProvinceName,
1219 jurisdictionOfIncorporationCountryName
1221 ** libgnutls: Added support for DSA signing/verifying with bit
1224 ** libgnutls-extra: When in FIPS mode gnutls_global_init_extra()
1225 has to be called to register any required md5 handlers.
1227 ** libgnutls: Internal buffering code was replaced by simpler
1228 code contributed by Jonathan Bastien-Filiatrault.
1230 ** libgnutls: Internal API for extensions augmented to allow
1231 safe storing and loading of data on resumption. This allows writing
1232 self-contained extensions (when possible). As a side effect
1233 the OPRFI extension was removed.
1235 ** libgnutls: Added support for DSA-SHA256 and DSA-SHA224
1237 ** libgnutls: Added PKCS #11 support and an API to access objects in
1238 gnutls/pkcs11.h. Currently certificates and public keys can be
1239 imported from tokens, and operations can be performed on private keys.
1241 ** libgnutls: Added abstract gnutls_privkey_t and gnutls_pubkey_t
1243 ** libgnutls: Added initial support for the nettle library. It uses
1244 the system's random generator for seeding. That is /dev/urandom in Linux,
1245 system calls in Win32 and EGD on other systems.
1247 ** libgnutls: Corrected issue on the %SSL3_RECORD_VERSION priority string. It now
1248 works even when resuming a session.
1250 ** libgnutls: Added gnutls_certificate_set_retrieve_function() to replace the
1251 similar gnutls_certificate_set_server_retrieve_function() and
1252 gnutls_certificate_set_client_retrieve_function(). In addition it support
1253 PKCS #11 private keys.
1255 ** libgnutls: Added gnutls_pkcs11_copy_x509_crt(), gnutls_pkcs11_copy_x509_privkey(),
1256 and gnutls_pkcs11_delete_url() to allow copying and deleting data in tokens.
1258 ** libgnutls: Added gnutls_sec_param_to_pk_bits() et al. to allow select bit
1259 sizes for private keys using a human understandable scale.
1261 ** certtool: Added new options: --pkcs11-list-tokens, --pkcs11-list-all
1262 --pkcs11-list-all-certs, --pkcs11-list-trusted, --pkcs11-list-certs,
1263 --pkcs11-delete-url, --pkcs11-write
1265 certtool: The --pkcs-cipher is taken into account when generating a
1266 private key. The default cipher used now is aes-128. The old behavior can
1267 be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1269 certtool: Added --certificate-pubkey to print the public key of the
1272 ** gnutls-cli/gnutls-serv: --x509cafile, --x509certfile and --x509keyfile
1273 can now accept a PKCS #11 URL in addition to a file. This will allow for
1274 example to use the Gnome-keyring trusted certificate list to verify
1275 connections using a url such as:
1276 pkcs11:token=Root%20CA%20Certificates;serial=1%3AROOTS%3ADEFAULT;model=1%2E0;manufacturer=Gnome%20Keyring

1357 * Version 2.10.1 (released 2010-07-25)
1359 ** libgnutls: Added support for broken certificates that indicate RSA
1362 ** gnutls-cli: Allow verification using V1 CAs.
1364 ** libgnutls: gnutls_x509_privkey_import() will fallback to
1365 gnutls_x509_privkey_import_pkcs8() without a password, if it
1366 is unable to decode the key.
1368 ** libgnutls: Correctly deinitialize crypto API functions to prevent
1369 a memory leak. Reported by Mads Kiilerich.
1371 ** certtool: If asked to generate DSA keys of size more than 1024 bits,
1372 issue a warning, that the output key might not be working everywhere.
1374 ** certtool: The --pkcs-cipher is taken into account when generating a
1375 private key. The default cipher used now is aes-128. The old behavior
1376 can be simulated by specifying "--pkcs-cipher 3des-pkcs12".
1378 ** API and ABI modifications:
1379 No changes since last version.
1381 * Version 2.10.0 (released 2010-06-25)
1383 ** API and ABI modifications:
1384 No changes since last version.
1386 * Version 2.9.12 (released 2010-06-17)
1388 ** gnutls-cli: Make --starttls work again.
1389 Problem introduced in patch to use read() instead of fgets() committed
1392 ** API and ABI modifications:
1393 No changes since last version.
1395 * Version 2.9.11 (released 2010-06-07)
1397 ** libgnutls: Removed two APIs related to safe renegotiation.
1398 Use priority strings instead. The APIs were
1399 gnutls_safe_negotiation_set_initial and gnutls_safe_renegotiation_set.
1400 (Remember that we don't promise ABI stability during development
1401 series, so this doesn't cause an shared library ABI increment.)
1403 ** tests: More self testing of safe renegotiation extension.
1404 See tests/safe-renegotiation/README for more information.
1406 ** doc: a PDF version of the API reference manual (GTK-DOC) is now built.
1408 ** doc: Terms 'GNUTLS' and 'GNU TLS' were changed to 'GnuTLS' for consistency.
1410 ** API and ABI modifications:
1411 gnutls_safe_negotiation_set_initial: REMOVED.
1412 gnutls_safe_renegotiation_set: REMOVED.
1414 * Version 2.9.10 (released 2010-04-22)
1416 ** libgnutls: Time verification extended to trusted certificate list.
1417 Unless new constant GNUTLS_VERIFY_DISABLE_TRUSTED_TIME_CHECKS flag is
1420 ** certtool: Display postalCode and Name X.509 DN attributes correctly.
1421 Based on patch by Pavan Konjarla. Adds new constant
1422 GNUTLS_OID_X520_POSTALCODE and GNUTLS_OID_X520_NAME.
1424 ** libgnutls: Added Steve Dispensa's patch for safe renegotiation (RFC 5746)
1425 Solves the issue discussed in:
1426 <http://www.ietf.org/mail-archive/web/tls/current/msg03928.html> and
1427 <http://www.ietf.org/mail-archive/web/tls/current/msg03948.html>.
1428 Note that to allow connecting to unpatched servers the full protection
1429 is only enabled if the priority string %SAFE_RENEGOTIATION is
1430 specified. You can check whether protection is in place by querying
1431 gnutls_safe_renegotiation_status(). New error codes
1432 GNUTLS_E_SAFE_RENEGOTIATION_FAILED and
1433 GNUTLS_E_UNSAFE_RENEGOTIATION_DENIED added.
1435 ** libgnutls: When checking openpgp self signature also check the signatures
1437 Ilari Liusvaara noticed and reported the issue and provided test
1440 ** libgnutls: Added cryptodev support (/dev/crypto).
1441 Tested with http://www.logix.cz/michal/devel/cryptodev/. Added
1442 benchmark utility for AES. Adds new error codes
1443 GNUTLS_E_CRYPTODEV_IOCTL_ERROR and GNUTLS_E_CRYPTODEV_DEVICE_ERROR.
1445 ** libgnutls: Exported API to access encryption and hash algorithms.
1446 The new API functions are gnutls_cipher_decrypt, gnutls_cipher_deinit,
1447 gnutls_cipher_encrypt, gnutls_cipher_get_block_size,
1448 gnutls_cipher_init, gnutls_hash, gnutls_hash_deinit, gnutls_hash_fast,
1449 gnutls_hash_get_len, gnutls_hash_init, gnutls_hash_output,
1450 gnutls_hmac, gnutls_hmac_deinit, gnutls_hmac_fast,
1451 gnutls_hmac_get_len, gnutls_hmac_init, gnutls_hmac_output. New API
1452 constants are GNUTLS_MAC_SHA224 and GNUTLS_DIG_SHA224.
1454 ** libgnutls: Added gnutls_certificate_set_verify_function() to allow
1455 verification of certificate upon receipt rather than waiting until the
1456 end of the handshake.
1458 ** libgnutls: Don't send alerts during handshake.
1459 Instead new error code GNUTLS_E_UNKNOWN_SRP_USERNAME is added.
1461 ** certtool: Corrected two issues that affected certificate request generation.
1462 (1) Null padding is added on integers (found thanks to Wilankar Trupti),
1463 (2) In optional SignatureAlgorithm parameters field for DSA keys the DSA
1464 parameters were added. Those were rejected by Verisign. Gnutls no longer adds
1465 those parameters there since other implementations don't do either and having
1466 them does not seem to offer anything (anyway you need the signer's certificate
1467 to verify thus public key will be available). Found thanks to Boyan Kasarov.
1468 This however has the side-effect that public key IDs shown by certtool are
1469 now different than previous gnutls releases.
1470 (3) the option --pgp-certificate-info will verify self signatures
1472 ** certtool: Allow exporting of Certificate requests on DER format.
1474 ** certtool: New option --no-crq-extensions to avoid extensions in CSRs.
1476 ** gnutls-cli: Handle reading binary data from server.

1541 * Version 2.9.8 (released 2009-11-05)
1543 ** libgnutls: Fix for memory leaks on interrupted handshake.
1544 Reported by Tang Tong.
1546 ** libgnutls: Addition of support for TLS 1.2 signature algorithms
1547 ** extension and certificate verify field.
1548 This requires changes for TLS 1.2 servers and clients that use
1549 callbacks for certificate retrieval. They are now required to check
1550 with gnutls_sign_algorithm_get_requested() whether the certificate
1551 they send complies with the peer's preferences in signature
1554 ** libgnutls: In server side when resuming a session do not overwrite the
1555 ** initial session data with the resumed session data.
1557 ** libgnutls: Added support for AES-128, AES-192 and AES-256 in PKCS #8
1559 This affects also PKCS #12 encoded files. This adds the following new
1560 enums: GNUTLS_CIPHER_AES_192_CBC, GNUTLS_PKCS_USE_PBES2_AES_128,
1561 GNUTLS_PKCS_USE_PBES2_AES_192, GNUTLS_PKCS_USE_PBES2_AES_256.
1563 ** libgnutls: Fix PKCS#12 encoding.
1564 The error you would get was "The OID is not supported.". Problem
1565 introduced for the v2.8.x branch in 2.7.6.
1567 ** certtool: Added the --pkcs-cipher option.
1568 To explicitely specify the encryption algorithm to use.
1570 ** tests: Added "pkcs12_encode" self-test to check PKCS#12 functions.
1572 ** tests: Fix time bomb in chainverify self-test.
1573 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
1574 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3925>.
1576 ** tests: Fix expired cert in chainverify self-test.
1578 ** i18n: Vietnamese translation updated.

1626 ** libgnutls: Client-side TLS 1.2 and SHA-256 ciphersuites now works.
1627 The new supported ciphersuites are AES-128/256 in CBC mode with
1628 ANON-DH/RSA/DHE-DSS/DHE-RSA. Contributed by Daiki Ueno. Further,
1629 SHA-256 is now the preferred default MAC (however it is only used with
1632 ** libgnutls: Make OpenPGP hostname checking work again.
1633 The patch to resolve the X.509 CN/SAN issue accidentally broken
1634 OpenPGP hostname comparison.
1636 ** libgnutls: When printing X.509 certificates, handle XMPP SANs better.
1637 Reported by Howard Chu <hyc@symas.com> in
1638 <https://savannah.gnu.org/support/?106975>.
1640 ** Fix use of deprecated types internally.
1641 Use of deprecated types in GnuTLS from now on will lead to a compile
1642 error, to prevent this from happening again.
1644 ** API and ABI modifications:
1645 No changes since last version.
1647 * Version 2.9.3 (released 2009-08-19)
1649 ** libgnutls: Support for TLS tickets was contributed by Daiki Ueno.
1650 The new APIs are gnutls_session_ticket_enable_client,
1651 gnutls_session_ticket_enable_server, and
1652 gnutls_session_ticket_key_generate.
1654 ** gnutls-cli, gnutls-serv: New parameter --noticket to disable TLS tickets.

1661 * Version 2.9.2 (released 2009-08-14)
1663 ** libgnutls: Fix problem with NUL bytes in X.509 CN and SAN fields.
1664 By using a NUL byte in CN/SAN fields, it was possible to fool GnuTLS
1665 into 1) not printing the entire CN/SAN field value when printing a
1666 certificate and 2) cause incorrect positive matches when matching a
1667 hostname against a certificate. Some CAs apparently have poor
1668 checking of CN/SAN values and issue these (arguable invalid)
1669 certificates. Combined, this can be used by attackers to become a
1670 MITM on server-authenticated TLS sessions. The problem is mitigated
1671 since attackers needs to get one certificate per site they want to
1672 attack, and the attacker reveals his tracks by applying for a
1673 certificate at the CA. It does not apply to client authenticated TLS
1674 sessions. Research presented independently by Dan Kaminsky and Moxie
1675 Marlinspike at BlackHat09. Thanks to Tomas Hoger <thoger@redhat.com>
1676 for providing one part of the patch. [GNUTLS-SA-2009-4] [CVE-2009-2730].
1678 ** libgnutls: Fix rare failure in gnutls_x509_crt_import.
1679 The function may fail incorrectly when an earlier certificate was
1680 imported to the same gnutls_x509_crt_t structure.
1682 ** minitasn1: Internal copy updated to libtasn1 v2.3.
1684 ** libgnutls: Fix return value of gnutls_certificate_client_get_request_status.
1685 Before it always returned false. Reported by Peter Hendrickson

1695 ** libgnutls: Fix PKCS#12 decryption from password.
1696 The encryption key derived from the password was incorrect for (on
1697 average) 1 in every 128 input for random inputs. Reported by "Kukosa,

1713 ** libgnutls: Relax checking of required libtasn1/libgcrypt versions.
1714 Before we required that the runtime library used the same (or more
1715 recent) libgcrypt/libtasn1 as it was compiled with. Now we just check
1716 that the runtime usage is above the minimum required. Reported by
1717 Marco d'Itri <md@linux.it> via Andreas Metzler
1718 <ametzler@downhill.at.eu.org> in <http://bugs.debian.org/540449>.
1720 ** tests: Added new self-test pkcs12_s2k_pem to detect MPI bit length error.
1722 ** tests: Improved test vectors in self-test pkcs12_s2k.
1724 ** tests: Added new self-test dn2 to detect off-by-one size error.

1755 ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value.
1756 VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti
1757 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.
1759 Note: As a side effect of this change, the "public key identifier"
1760 value computed for a certificate using this version of GnuTLS will be
1761 different from values computed using earlier versions of GnuTLS.
1763 ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the
1764 ** optional SignatureAlgorithm parameter field.
1765 VeriSign rejected these CSRs. They are stricly speaking not needed
1766 since you need the signer's certificate to verify the certificate
1767 signature anyway. Reported by Wilankar Trupti
1768 <trupti.wilankar@hp.com> and Boyan Kasarov <bkasarov@gmail.com>.

2027 No offically supported interfaces have been modified or removed. The
2028 library should be completely backwards compatible on both the source
2031 The shared library no longer exports some symbols that have never been
2032 officially supported, i.e., not mentioned in any of the header files.
2038 Normally when symbols are removed, the shared library version has to
2039 be incremented. This leads to a significant cost for everyone using
2040 the library. Because none of the above symbols have ever been
2041 intended for use by well-behaved applications, we decided that the it
2042 would be better for those applications to pay the price rather than
2043 incurring problems on the majority of applications.
2045 If it turns out that applications have been using unofficial
2046 interfaces, we will need to release a follow-on release on the v2.8
2047 branch to exports additional interfaces. However, initial testing
2048 suggests that few if any applications have been using any of the
2051 Although not a new change compared to 2.6.x, we'd like to remind you
2052 interfaces have been modified so that X.509 chain verification now
2053 also checks activation/expiration times on certificates. The affected
2056 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2057 gnutls_certificate_verify_peers: Likewise.
2058 gnutls_certificate_verify_peers2: Likewise.
2059 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2060 GNUTLS_CERT_EXPIRED: ADDED.
2061 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2063 This change in behaviour was made during the GnuTLS 2.6.x cycle, and
2064 we gave our rationale for it in earlier release notes.
2066 The following symbols have been added to the library:

2222 * Version 2.7.8 (released 2009-05-03)
2224 ** libgnutls: Fix DSA key generation.
2225 Merged from stable branch. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2227 ** libgnutls: Check expiration/activation time on untrusted certificates.
2228 Merged from stable branch. Reported by Romain Francoise
2229 <romain@orebokech.com>. This changes the semantics of
2230 gnutls_x509_crt_list_verify, which in turn is used by
2231 gnutls_certificate_verify_peers and gnutls_certificate_verify_peers2.
2232 We add two new gnutls_certificate_status_t codes for reporting the new
2233 error condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED.
2234 We also add a new gnutls_certificate_verify_flags flag,
2235 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2236 behaviour. [GNUTLS-SA-2009-3] [CVE-2009-1417]
2238 ** lib: Linker version scripts reduces number of exported symbols.
2239 The linker version script now lists all exported ABIs explicitly, to
2240 avoid accidentally exporting unintended functions. Compared to
2241 before, most symbols beginning with _gnutls* are no longer exported.
2242 These functions have never been intended for use by applications, and
2243 there were no prototypes for these function in the public header
2244 files. Thus we believe it is possible to do this without incrementing
2245 the library ABI version which normally has to be done when removing an
2248 ** lib: Limit exported symbols on systems without LD linker scripts.
2249 Before all symbols were exported. Now we limit the exported symbols
2250 to (for libgnutls and libgnutls-extra) gnutls* and (for libgnutls)
2251 _gnutls*. This is a superset of the actual supported ABI, but still
2252 an improvement compared to before. This is implemented using Libtool
2253 -export-symbols-regex. It is more portable than linker version
2256 ** libgnutls: Incremented CURRENT/AGE libtool version to reflect new symbols.
2257 This should have been done in the last release.
2259 ** gnutls-serv: Listen on all interfaces, including both IPv4 and IPv6.
2260 Reported by Peter Hendrickson <pdh@wiredyne.com> in
2261 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3476>.
2263 ** doc: Improved sections for the info manual.
2264 We now follow the advice given by the texinfo manual on which
2265 directory categories to use. In particular, libgnutls moved from the
2266 'GNU Libraries' section to the 'Software libraries' and the command
2267 line tools moved from 'Network Applications' to 'System
2270 ** API and ABI modifications:
2271 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2272 gnutls_certificate_verify_peers: Likewise.
2273 gnutls_certificate_verify_peers2: Likewise.
2274 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2275 GNUTLS_CERT_EXPIRED: ADDED.
2276 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2278 * Version 2.7.7 (released 2009-04-20)
2280 ** libgnutls: Applied patch by Cedric Bail to add functions
2281 gnutls_x509_crt_verify_hash() and gnutls_x509_crt_get_verify_algorithm().
2283 ** gnutls.pc: Add -ltasn1 to 'pkg-config --libs --static gnutls' output.
2284 Reported by Andreas Metzler <ametzler@downhill.at.eu.org> in
2285 <http://article.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3467>.
2287 ** minitasn1: Internal copy updated to libtasn1 v1.8.
2288 GnuTLS is also internally ready to be used with libtasn1 v2.0.
2290 ** doc: Fix build failure of errcodes/printlist.
2291 Reported by Roman Bogorodskiy <novel@FreeBSD.org> in
2292 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3435>.
2294 ** i18n: The GnuTLS gettext domain is now 'libgnutls' instead of 'gnutls'.
2295 It is currently only used by the core library. This will enable a new
2296 domain 'gnutls' for translations of the command line tools.
2298 ** Corrected possible memory corruption on signature verification failure.
2299 Reported by Miroslav Kratochvil <exa.exa@gmail.com>
2301 ** API and ABI modifications:
2302 gnutls_x509_crt_verify_hash: ADDED
2303 gnutls_x509_crt_get_verify_algorithm: ADDED
2305 * Version 2.7.6 (released 2009-02-27)
2307 ** certtool: Query for multiple dnsName subjectAltName in interactive mode.
2308 This applies both to generating certificates and certificate requests.
2310 ** pkix.asn: Removed unneeded definitions to reduce memory usage.
2312 ** gnutls-cli: No longer accepts V1 CAs by default during X.509 chain verify.
2313 Use --priority NORMAL:%VERIFY_ALLOW_X509_V1_CA_CRT to permit V1 CAs to
2314 be used for chain verification.
2316 ** gnutls-serv: No longer disable MAC padding by default.
2317 Use --priority NORMAL:%COMPAT to disable MAC padding again.
2319 ** gnutls-cli: Certificate information output format changed.
2320 The tool now uses libgnutls' functions to print certificate
2321 information. This avoids code duplication.
2323 ** libgnutls: New priority strings %VERIFY_ALLOW_SIGN_RSA_MD5
2324 ** and %VERIFY_ALLOW_X509_V1_CA_CRT.
2325 They can be used to override the default certificate chain validation
2328 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2329 specify the client hello message record version. Used to overcome buggy
2330 TLS servers. Report by Martin von Gagern.
2332 ** libgnutls: gnutls_x509_crt_print prints signature algorithm in oneline mode.
2334 ** libgnutls: gnutls_openpgp_crt_print supports oneline mode.
2336 ** doc: Update gnutls-cli and gnutls-serv --help output descriptions.
2338 ** API and ABI modifications:
2339 No changes since last version.
2341 * Version 2.7.5 (released 2009-02-06)
2343 ** libgnutls: Accept chains where intermediary certs are trusted.
2344 Before GnuTLS needed to validate the entire chain back to a
2345 self-signed certificate. GnuTLS will now stop looking when it has
2346 found an intermediary trusted certificate. The new behaviour is
2347 useful when chains, for example, contains a top-level CA, an
2348 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2349 To avoid chain validation errors due to the RSA-MD5 cert, you can
2350 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2351 The signature on trusted certificates are not checked, so the chain
2352 has a chance to validate correctly. Reported by "Douglas E. Engert"
2353 <deengert@anl.gov> in
2354 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2356 ** libgnutls: result_size in gnutls_hex_encode now holds
2357 the size of the result. Report by John Brooks <special@dereferenced.net>.
2359 ** libgnutls: gnutls_handshake when sending client hello during a
2360 rehandshake, will not offer a version number larger than the current.
2361 Reported by Tristan Hill <stan@saticed.me.uk>.
2363 ** libgnutls: Permit V1 Certificate Authorities properly.
2364 Before they were mistakenly rejected even though
2365 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2366 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2367 "Douglas E. Engert" <deengert@anl.gov> in
2368 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2370 ** API and ABI modifications:
2371 No changes since last version.
2373 * Version 2.7.4 (released 2009-01-07)
2375 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2376 This is a bugfix -- the previous attempt to do this from internal x509
2377 certificate verification procedures did not return the correct value
2378 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2379 <dkg@fifthhorseman.net> in
2380 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2381 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2382 Gillmor <dkg@fifthhorseman.net>.
2384 ** libgnutls: New interface to get key id for certificate requests.
2385 Patch from David MarÃn Carreño <davefx@gmail.com> in
2386 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3321>.
2388 ** libgnutls: gnutls_x509_crq_print will now also print public key id.
2390 ** certtool: --verify-chain now prints results of using library verification.
2391 Earlier, certtool --verify-chain used its own validation algorithm
2392 which wasn't guaranteed to give the same result as the libgnutls
2393 internal validation algorithm. Now this command print a new final
2394 line with header 'Chain verification output:' that contains the result
2395 from using the internal verification algorithm on the same chain.
2397 ** tests: Add crq_key_id self-test of gnutls_x509_crq_get_key_id.
2399 ** API and ABI modifications:
2400 gnutls_x509_crq_get_key_id: ADDED.
2402 * Version 2.7.3 (released 2008-12-10)
2404 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2405 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
2406 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
2407 Andreas Metzler <ametzler@downhill.at.eu.org> in
2408 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2410 ** libgnutls: Libgcrypt initialization changed.
2411 If libgcrypt has not already been initialized, GnuTLS will now
2412 initialize libgcrypt with disabled secure memory. Initialize
2413 libgcrypt explicitly in your application if you want to enable secure
2414 memory. Before GnuTLS initialized libgcrypt to use GnuTLS's memory
2415 allocation functions, which doesn't use secure memory, so there is no
2416 real change in behaviour.
2418 ** libgnutls: Fix memory leak in PSK authentication.
2419 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2420 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2422 ** libgnutls: Small byte reads via gnutls_record_recv() optimized.
2424 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2425 It needs to be invoked before libgcrypt is initialized.
2427 ** gnutls-cli: Return non-zero exit code on error conditions.
2429 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2431 ** tests: Added chainverify self-test that tests X.509 chain verifications.
2433 ** API and ABI modifications:
2434 No changes since last version.
2436 * Version 2.7.2 (released 2008-11-18)
2438 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2439 The flaw makes it possible for man in the middle attackers (i.e.,
2440 active attackers) to assume any name and trick GnuTLS clients into
2441 trusting that name. Thanks for report and analysis from Martin von
2442 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2444 Any updates with more details about this vulnerability will be added
2445 to <http://www.gnu.org/software/gnutls/security.html>
2447 ** libgnutls: Fix namespace issue with version symbols.
2448 The symbols LIBGNUTLS_VERSION, LIBGNUTLS_VERSION_MAJOR,
2449 LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, and
2450 LIBGNUTLS_VERSION_NUMBER were renamed to GNUTLS_VERSION_NUMBER,
2451 GNUTLS_VERSION_MAJOR, GNUTLS_VERSION_MINOR, GNUTLS_VERSION_PATCH, and
2452 GNUTLS_VERSION_NUMBER respectively. The old symbols will continue to
2453 work but are deprecated.
2455 ** certtool: allow setting arbitrary key purpose object identifiers.
2457 ** libgnutls: Fix detection of C99 macros, to make debug logging work again.
2459 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2460 Reported by Kevin Quick <quick@sparq.org> in
2461 <https://savannah.gnu.org/support/index.php?106454>.
2463 ** libgnutls-extra: Make building with LZO compression work again.
2464 Build failure reported by Arfrever Frehtes Taifersar Arahesis
2465 <arfrever.fta@gmail.com> in
2466 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3194>.
2468 ** libgnutls: Change detection of when to use a linker version script.
2469 Use --enable-ld-version-script or --disable-ld-version-script to
2470 override auto-detection logic.
2472 ** doc: Change license on the manual to GFDLv1.3+.
2474 ** doc: GTK-DOC fixes for new splitted configuration system.

2479 Tests regressions of the GNUTLS-SA-2008-3 security problem, and the
2480 follow-on problem with crashes on length 1 certificate chains.
2482 ** gnulib: Deprecated modules removed.
2483 Modules include memchr and memcmp.
2485 ** Fix warnings and build GnuTLS with more warnings enabled.
2487 ** minitasn1: Internal copy updated to libtasn1 v1.7.

2502 * Version 2.7.1 (released 2008-10-31)
2504 ** certtool: print a PKCS #8 key even if it is not encrypted.
2506 ** Old libgnutls.m4 and libgnutls-config scripts removed.
2507 Please use pkg-config instead.
2509 ** Configuration system modified.
2510 There is now a configure script in lib/ and libextra/ as well, because
2511 gnulib works better with a config.h per gnulib directory.

2574 Reported by Miroslav Kratochvil <exa.exa@gmail.com>. See the advisory
2575 for more details. [GNUTLS-SA-2009-1] [CVE-2009-1415]
2577 ** libgnutls: Fix DSA key generation.
2578 Noticed when investigating the previous GNUTLS-SA-2009-1 problem. All
2579 DSA keys generated using GnuTLS 2.6.x are corrupt. See the advisory
2580 for more details. [GNUTLS-SA-2009-2] [CVE-2009-1416]
2582 ** libgnutls: Check expiration/activation time on untrusted certificates.
2583 Reported by Romain Francoise <romain@orebokech.com>. Before the
2584 library did not check activation/expiration times on certificates, and
2585 was documented as not doing so. We have realized that many
2586 applications that use libgnutls, including gnutls-cli, fail to perform
2587 proper checks. Implementing similar logic in all applications leads
2588 to code duplication. Hence, we decided to check whether the current
2589 time (as reported by the time function) is within the
2590 activation/expiration period of certificates when verifying untrusted
2593 This changes the semantics of gnutls_x509_crt_list_verify, which in
2594 turn is used by gnutls_certificate_verify_peers and
2595 gnutls_certificate_verify_peers2. We add two new
2596 gnutls_certificate_status_t codes for reporting the new error
2597 condition, GNUTLS_CERT_NOT_ACTIVATED and GNUTLS_CERT_EXPIRED. We also
2598 add a new gnutls_certificate_verify_flags flag,
2599 GNUTLS_VERIFY_DISABLE_TIME_CHECKS, that can be used to disable the new
2602 More details about the vulnerabilities will be posted at
2603 <http://www.gnu.org/software/gnutls/security.html>.
2605 ** gnutls-cli, gnutls-cli-debug: Fix AIX build problem.
2606 Reported by LAUPRETRE François (P) <francois.laupretre@ratp.fr> in
2607 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3468>.
2609 ** tests: Fix linking of tests/openpgp/keyring self-test.
2610 Reported by Daniel Black in <https://savannah.gnu.org/support/?106543>.
2612 ** API and ABI modifications:
2613 gnutls_x509_crt_list_verify: CHANGED, checks activation/expiration times.
2614 gnutls_certificate_verify_peers: Likewise.
2615 gnutls_certificate_verify_peers2: Likewise.
2616 GNUTLS_CERT_NOT_ACTIVATED: ADDED.
2617 GNUTLS_CERT_EXPIRED: ADDED.
2618 GNUTLS_VERIFY_DISABLE_TIME_CHECKS: ADDED.
2620 * Version 2.6.5 (released 2009-04-11)
2622 ** libgnutls: Added %SSL3_RECORD_VERSION priority string that allows to
2623 specify the client hello message record version. Used to overcome buggy
2624 TLS servers. Report by Martin von Gagern.
2626 ** GnuTLS no longer uses the libtasn1-config script to find libtasn1.
2627 Libtasn1 0.3.4 or later is required. This is to align with the
2628 upcoming libtasn1 v2.0 release that doesn't have a libtasn1-script.
2630 ** API and ABI modifications:
2631 No changes since last version.
2633 * Version 2.6.4 (released 2009-02-06)
2635 ** libgnutls: Accept chains where intermediary certs are trusted.
2636 Before GnuTLS needed to validate the entire chain back to a
2637 self-signed certificate. GnuTLS will now stop looking when it has
2638 found an intermediary trusted certificate. The new behaviour is
2639 useful when chains, for example, contains a top-level CA, an
2640 intermediary CA signed using RSA-MD5, and an end-entity certificate.
2641 To avoid chain validation errors due to the RSA-MD5 cert, you can
2642 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
2643 The signature on trusted certificates are not checked, so the chain
2644 has a chance to validate correctly. Reported by "Douglas E. Engert"
2645 <deengert@anl.gov> in
2646 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2648 ** libgnutls: result_size in gnutls_hex_encode now holds
2649 the size of the result. Report by John Brooks <special@dereferenced.net>.
2651 ** libgnutls: gnutls_handshake when sending client hello during a
2652 rehandshake, will not offer a version number larger than the current.
2653 Reported by Tristan Hill <stan@saticed.me.uk>.
2655 ** libgnutls: Permit V1 Certificate Authorities properly.
2656 Before they were mistakenly rejected even though
2657 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
2658 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by
2659 "Douglas E. Engert" <deengert@anl.gov> in
2660 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
2662 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
2663 This is a bugfix -- the previous attempt to do this from internal x509
2664 certificate verification procedures did not return the correct value
2665 for certificates using a weak hash. Reported by Daniel Kahn Gillmor
2666 <dkg@fifthhorseman.net> in
2667 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3332>,
2668 debugged and patch by Tomas Mraz <tmraz@redhat.com> and Daniel Kahn
2669 Gillmor <dkg@fifthhorseman.net>.
2671 ** libgnutls: Fix compile error with Sun CC.
2672 Reported by Jeff Cai <jeff.cai@sun.com> in
2673 <https://savannah.gnu.org/support/?106549>.
2675 ** API and ABI modifications:
2676 No changes since last version.
2678 * Version 2.6.3 (released 2008-12-12)
2680 ** libgnutls: Fix chain verification for chains that ends with RSA-MD2 CAs.
2681 Reported by Michael Kiefer <Michael-Kiefer@web.de> in
2682 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=507633> forwarded by
2683 Andreas Metzler <ametzler@downhill.at.eu.org> in
2684 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3309>.
2686 ** libgnutls: Fix memory leak in PSK authentication.
2687 Reported by Michael Weiser <michael@weiser.dinsnail.net> in
2688 <http://permalink.gmane.org/gmane.network.gnutls.general/1465>.
2690 ** certtool: Move gcry_control(GCRYCTL_ENABLE_QUICK_RANDOM, 0) call earlier.
2691 It needs to be invoked before libgcrypt is initialized.
2693 ** gnutls-cli: Return non-zero exit code on error conditions.
2695 ** gnutls-cli: Corrected bug which caused a rehandshake request to be ignored.
2697 ** API and ABI modifications:
2698 No changes since last version.
2700 * Version 2.6.2 (released 2008-11-12)
2702 ** libgnutls: Fix crash in X.509 validation code for self-signed certificates.
2703 The patch to fix the security problem GNUTLS-SA-2008-3 introduced a
2704 problem for certificate chains that contained just one self-signed
2705 certificate. Reported by Michael Meskes <meskes@debian.org> in
2706 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505279>.
2708 ** API and ABI modifications:
2709 No changes since last version.
2711 * Version 2.6.1 (released 2008-11-10)
2713 ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3]
2714 The flaw makes it possible for man in the middle attackers (i.e.,
2715 active attackers) to assume any name and trick GnuTLS clients into
2716 trusting that name. Thanks for report and analysis from Martin von
2717 Gagern <Martin.vGagern@gmx.net>. [CVE-2008-4989]
2719 Any updates with more details about this vulnerability will be added
2720 to <http://www.gnu.org/software/gnutls/security.html>
2722 ** libgnutls: Add missing prototype for gnutls_srp_set_prime_bits.
2723 Reported by Kevin Quick <quick@sparq.org> in
2724 <https://savannah.gnu.org/support/index.php?106454>.
2726 ** libgnutls-extra: Protect internal symbols with static.
2727 Fixes problem when linking certtool statically. Tiny patch from Aaron
2728 Ucko <ucko@ncbi.nlm.nih.gov>.
2730 ** libgnutls-openssl: Fix patch against X509_get_issuer_name.
2731 It incorrectly returned the subject DN instead of issuer DN in v2.6.0.
2732 Thanks to Thomas Viehmann <tv@beamnet.de> for report.
2734 ** certtool: Print a PKCS #8 key even if it is not encrypted.
2736 ** tests: Make tests compile when using internal libtasn1.
2737 Patch by ludo@gnu.org (Ludovic Courtès).
2739 ** API and ABI modifications:
2740 No changes since last version.
2742 * Version 2.6.0 (released 2008-10-06)
2744 ** libgnutls: Correct printing and parsing of IPv6 addresses.
2746 ** libgnutls-openssl: fix out of bounds access.
2747 Problem in X509_get_subject_name and X509_get_issuer_name. Tiny patch
2748 from Thomas Viehmann <tv@beamnet.de>.
2750 ** certtool: Use inet_pton for parsing IPv6 addresses.
2752 ** Major changes compared to the v2.4 branch:
2754 *** Added API to replace and update the crypto backend.
2756 *** certtool: can add several subject alternative names via template file.
2758 *** opencdk: Parse (but not decrypt) encrypted secret keys.
2760 *** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2761 either set or append alternative names. It can also handle binary structures
2762 such as IP addresses.
2764 *** libgnutls: New function to set minimum acceptable SRP bits.
2765 The function is gnutls_srp_set_prime_bits.
2767 *** libgnutls: Add interface to deal with public key and signature algorithms.
2768 The functions are called gnutls_pk_list, gnutls_pk_get_id,
2769 gnutls_sign_list, and gnutls_sign_get_id.
2771 *** libgnutls: New interfaces to get name of public key and signing algorithms.
2772 The functions are gnutls_sign_get_name and gnutls_pk_get_name.
2774 *** libgnutls: New API to get a string corresponding to a error symbol.
2775 The function is gnutls_strerror_name.
2777 *** libgnutls: New API to set the public parameters in a certificate request
2778 *** from a private key.
2779 The function is gnutls_x509_crq_set_key_rsa_raw.
2781 *** libgnutls: New API to set a callback to extract TLS Finished data.
2782 The function to register is gnutls_session_set_finished_function and
2783 it takes a callback of the gnutls_finished_callback_func type.
2785 *** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
2787 *** libgnutls: New interface to register a new TLS extension handler.
2788 The new function gnutls_ext_register can be used to register handlers
2789 for specific TLS extension types. The callback functions have the new
2790 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
2791 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
2794 *** libgnutls-extra: Add function to work with Libgcrypt in FIPS mode.
2795 The function is gnutls_register_md5_handler. When libgcrypt is in
2796 FIPS mode, MD5 is disabled, but TLS normally requires use of MD5 in
2799 *** API/ABI changes in GnuTLS 2.6
2800 No functions have been removed or modified. The library should be
2801 fully backwards compatible on both the source and binary level.
2803 A new header file <gnutls/crypto.h> have been added. It contains
2804 definitions related to replacing the internal crypto functionality.
2805 All definitions and the header itself is experimental but supported.
2807 We have realized that the symbols TLS_MASTER_SIZE and TLS_RANDOM_SIZE
2808 does not use the normal namespace. We have added GNUTLS_MASTER_SIZE
2809 and GNUTLS_RANDOM_SIZE, but the old symbols are still defined.
2811 The following functions have been added to libgnutls:
2815 gnutls_crypto_bigint_register2
2816 gnutls_crypto_cipher_register2
2817 gnutls_crypto_digest_register2
2818 gnutls_crypto_mac_register2

2851 Report and patch by Jonathan Manktelow.
2853 ** libgnutls: crypto.h gnutls_pk_params_st changes allocation strategy.
2854 The parameters are now allocated in the structure itself.
2856 ** doc: Texinfo HTML manual uses a stylesheet to improve readability.
2858 ** tests: Scripts now use EXEEXT properly.
2859 Modern libtool doesn't create wrapper script, so the self tests need
2860 to invoke certtool.exe under MinGW32+Wine.
2862 ** Uses autoconf 2.63, automake 1.10.1, libtool 2.2.6a.
2863 Automake warnings are now also enabled.
2865 ** API and ABI modifications:
2866 gnutls_pk_params_st: MODIFIED
2868 * Version 2.5.8 (released 2008-09-21)
2870 ** certtool: updated so it can add several subject alternative names using
2873 ** libgnutls: gnutls_x509_crt_set_subject_alt_name() was added that can
2874 either set or append alternative names. It can also handle binary structures
2875 such as IP addresses.
2877 ** libgnutls: Fix crash in hashing code when using non-libgcrypt handlers.
2879 ** libgnutls: New function to set minimum acceptable SRP bits.
2880 The function is gnutls_srp_set_prime_bits. Tiny patch by Kevin Quick

2953 * Version 2.5.5 (released 2008-08-29)
2955 ** libgnutls: New API to get a string corresponding to a error symbol.
2956 The function is gnutls_strerror_name.
2958 ** libgnutls: Fix include paths so that building with internal libtasn1 works.
2959 Reported by "jth.net ApS" <info@jth.net>.
2961 ** libgnutls: Fix segmentation fault when generating private keys.
2962 Reported by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2964 ** libgnutls: Remove code to import certificate chains in PKCS#7 format.
2965 The code has not worked since v0.9.0 and apparently nobody has missed
2966 it, so we decided to remove the code rather than fix it. If you have
2967 old certificate chains stored in PKCS#7 format, you can convert them
2968 to a list of PEM certificates by using 'certtool --p7-info'. Reported
2969 by Christian Grothoff <christian@grothoff.org>.
2971 ** opencdk: Parse (but not decrypt) encrypted secret keys.
2972 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
2974 ** libgnutls: Fix many warnings.
2976 ** Included copy of libtasn1 is upgraded to version 1.5.
2978 ** Add French translation, thanks to Nicolas Provost.
2980 ** API and ABI modifications:
2981 gnutls_strerror_name: ADDED
2983 * Version 2.5.4 (released 2008-08-19)
2985 ** Fix secure memory initialization of libgcrypt.
2986 Reported by Joe Orton <joe@manyfish.co.uk> in
2987 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2992>.
2990 Reference to NIST SP 800-57 in the manual on key size recommendations.
2991 Added 'Since:' tags to new APIs for gtk-doc.
2993 ** API and ABI modifications:
2994 No changes since last version.
2996 * Version 2.5.3 (released 2008-08-14)
2998 ** libgnutls: New API to set the public parameters in a certificate request
2999 ** from a private key.
3000 The function is gnutls_x509_crq_set_key_rsa_raw. Inspired by
3001 discussion with "Zach C." <fxchip@gmail.com>.
3003 ** libgnutls: New API to set a callback to extract TLS Finished data.
3004 The function to register is gnutls_session_set_finished_function and
3005 it takes a callback of the gnutls_finished_callback_func type.
3007 ** libgnutls: Drop final comma after GNUTLS_CRT_PRINT_UNSIGNED_FULL in enum.
3008 Reported in <https://savannah.gnu.org/support/?106453>.
3010 ** libgnutls: Fix namespace problem with TLS_MASTER_SIZE and TLS_RANDOM_SIZE.
3011 The new names are GNUTLS_MASTER_SIZE and GNUTLS_RANDOM_SIZE. The old
3012 names are mapped to the new names in compat.h. These mappings will
3013 likely be removed more quickly than other mappings in that file due to
3014 the namespace violation.
3016 ** libgnutlsxx: Make it build when SRP is disabled.
3018 ** doc: Add doxygen files in doc/doxygen/.
3020 ** API and ABI modifications:
3021 gnutls_x509_crq_set_key_rsa_raw: ADDED

3025 GNUTLS_RANDOM_SIZE: ADDED
3026 TLS_MASTER_SIZE: DEPRECATED
3027 TLS_RANDOM_SIZE: DEPRECATED
3029 * Version 2.5.2 (released 2008-07-08)
3031 ** libgnutls: Fix bug in gnutls_dh_params_generate2.
3032 The prime and generator was swapped.
3034 ** libgnutls: New interface to register a new TLS extension handler.
3035 The new function gnutls_ext_register can be used to register handlers
3036 for specific TLS extension types. The callback functions have the new
3037 types gnutls_ext_recv_func and gnutls_ext_send_func. A type to
3038 classify TLS extensions, gnutls_ext_parse_type_t, has been added as
3041 ** Move more code for TLS/IA extension from libgnutls to libgnutls-extra.
3042 This was made possible by using the new gnutls_ext_register interface.
3043 The TLS/IA functionality has only been supported through the
3044 libgnutls-extra library, so it makes sense for the code to belong
3047 ** API and ABI modifications:
3048 gnutls_ext_recv_func: ADDED
3049 gnutls_ext_send_func: ADDED
3050 gnutls_ext_parse_type_t: ADDED

3062 ** Port fixes from v2.4.1 release, see below.
3064 ** Added API to replace and update the crypto backend.
3065 The header gnutls/crypto.h is now officially supported, and declares
3068 ** Rewritten opencdk crypto backend, to use the gnutls internal one.
3070 ** Update gnulib and translations.
3071 The gnulib gc crypto code has been removed since it was never finished
3072 and is no longer even used. An internal non-libgcrypt crypto
3073 implementation may be added in the future, but we'll decide that later

3089 ** libgnutls: Accept chains where intermediary certs are trusted.
3090 Before GnuTLS needed to validate the entire chain back to a
3091 self-signed certificate. GnuTLS will now stop looking when it has
3092 found an intermediary trusted certificate. The new behaviour is
3093 useful when chains, for example, contains a top-level CA, an
3094 intermediary CA signed using RSA-MD5, and an end-entity certificate.
3095 To avoid chain validation errors due to the RSA-MD5 cert, you can
3096 explicitly add the intermediary RSA-MD5 cert to your trusted certs.
3097 The signature on trusted certificates are not checked, so the chain
3098 has a chance to validate correctly. Reported by "Douglas E. Engert"

3100 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/3351>.
3102 ** libgnutls: Permit V1 Certificate Authorities properly.
3103 Before they were mistakenly rejected even though
3104 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT and/or
3105 GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT were supplied. Reported by

3109 ** libgnutls: deprecate X.509 validation chains using MD5 and MD2 signatures.
3110 This is a bugfix -- the previous attempt to do this from internal x509
3111 certificate verification procedures did not return the correct value
3112 for certificates using a weak hash. Reported by Daniel Kahn Gillmor

3197 No changes since last version.
3199 * Version 2.4.0 (released 2008-06-19)
3201 ** Major changes compared to the v2.2 branch:
3203 *** The OpenPGP sub-system has been improved and now supports subkeys.
3205 *** The PSK sub-system has been improved and now supports password
3206 *** derivation and PSK identity hints.
3207 The password derivation algorithms support is documented in
3208 draft-ietf-netconf-tls-02.txt.
3210 *** The certtool --inder and --outder has been replaced by --inraw and --outraw.
3211 This aligns terminology with OpenPGP, which doesn't use DER encoding.
3212 The old parameters will continue to work for some time.
3214 *** Certtool now confirm passwords and changes permissions of private key files.
3216 *** The default handshake size limit has been increased to 48kb.
3217 It appears as if some valid handshakes are large due to sending many
3218 CA certificates. (The earlier limit was 16kb.)
3220 *** LZO compression is now disabled by default.
3221 The main reason is that LZO compression in TLS is not standardized,
3222 but license compatiblity issues with minilzo triggered us to make this
3225 *** Improvements for cross-compilation to Windows and OpenWRT.
3227 *** The look of the GTK-DOC manual has been improved.
3228 Major developer visible changes compared to the v2.2 branch:
3230 *** Full OpenPGP support is part of libgnutls, licensed under the LGPL.
3232 *** New APIs to access the raw X.509 Subject and Issuer DN's and
3233 *** elements from the certificate credentials structure.
3234 Thanks to Joe Orton.
3236 *** New APIs to improve working with username/passwords and PSK.
3238 *** Names of constants to affect certificate printing changed.
3239 The constants are used for OpenPGP too, which the names didn't
3240 reflect, so the following name change has been made:
3243 GNUTLS_X509_CRT_FULL GNUTLS_CRT_PRINT_FULL
3244 GNUTLS_X509_CRT_ONELINE GNUTLS_CRT_PRINT_ONELINE
3245 GNUTLS_X509_CRT_UNSIGNED_FULL GNUTLS_CRT_PRINT_UNSIGNED_FULL
3247 The old names will be mapped to the new names for some time.
3249 *** The function gnutls_openpgp_privkey_get_id has been renamed to
3250 *** gnutls_openpgp_privkey_get_key_id.
3251 A compatibility mapping exists to avoid breaking API backwards
3254 *** Replaced all uses of alloca with malloc and free.
3256 *** We no longer build with -D_REENTRANT -D_THREAD_SAFE.
3257 We have been unable to find a documented rationale for this practice.
3259 *** Of course, many smaller fixes have been made, see the ChangeLog file.
3261 *** API/ABI changes in GnuTLS 2.4
3262 All OpenPGP related functions have been moved from libgnutls-extra to
3263 libgnutls, and several new functions have been added (see below).
3264 Before making the release, we discussed whether moving functions from
3265 libgnutls-extra to libgnutls would require us to increment the ABI
3266 version, but the general opinion was that this would not be required.
3267 All older functions continue to work the same. We are open to the
3268 possibility that this decision will lead to problem on some platform,
3269 and if it turns out that the Right Thing should have been to increment
3270 the shared library version, we would need to release an update within
3271 the 2.4.x branch that increments the shared library version.
3273 This release adds the following functions:
3275 gnutls_psk_client_get_hint
3276 gnutls_psk_set_server_credentials_hint
3277 gnutls_psk_netconf_derive_key
3279 Used to get/set the PSK identity hint, and derive PSK keys from
3280 passwords a'la netconf.
3282 gnutls_x509_dn_deinit
3283 gnutls_x509_dn_export
3284 gnutls_x509_dn_import
3287 Used to handle X.509 Certificate DN's directly.
3291 Converts a data buffer to hex. Useful for handling PSK/SRP shared
3294 gnutls_certificate_get_x509_cas
3295 gnutls_certificate_get_x509_crls
3296 gnutls_certificate_get_openpgp_keyring
3298 Functions for direct access to credential elements.
3300 gnutls_openpgp_crt_get_auth_subkey

3338 gnutls_openpgp_privkey_get_subkey_revoked_status
3339 gnutls_openpgp_privkey_set_preferred_key_id
3341 New OpenPGP related functions.
3343 The function gnutls_openpgp_crt_get_key_id is the same as the old
3344 from gnutls_openpgp_crt_get_id, see above.
3346 The release also adds a new header file 'gnutls/crypto.h', however it
3347 is currently not used.
3349 ** libgnutls [OpenPGP]: New APIs to retrieve fingerprint from OpenPGP subkeys.
3350 Contributed by Daniel Kahn Gillmor <dkg-debian.org@fifthhorseman.net>.
3352 ** API and ABI modifications:
3353 gnutls_openpgp_crt_get_subkey_fingerprint: ADDED.

3374 Reported by Sam Varshavchik <mrsam@courier-mta.com>.
3376 ** API and ABI modifications:
3377 No changes since last version.
3379 * Version 2.3.13 (released 2008-06-07)
3381 ** libgnutls [OpenPGP]: Make OpenPGP handshakes work again.
3383 ** doc/: Add psktool to info index. Some minor cleanups.
3385 ** tests/: Added non-forking TLS handshake test, see tests/mini.c.
3387 ** tests/: Added libgcrypt.supp which can be used with valgrind.
3388 The file suppresses the known libgcrypt memory leaks, so they aren't
3389 printed when you run valgrind on the gnutls self-tests. Use it as
3390 follows: valgrind --suppressions=libgcrypt.supp ./x509self or add
3391 '--suppressions=/home/you/src/gnutls/tests/libgcrypt.supp' to your
3394 ** tests/: Reduce amount of debugging output by default.
3395 Use --verbose for each test to get the full output.
3397 ** tests/: Fix memory leaks in several self-tests.
3398 None of the self tests should be leaking memory when running valgrind
3399 or similar tools. (Known exceptions are dhepskself, pskself, and
3400 set_pkcs12_cred, which appear likely to be due to memory leaks in the

3406 * Version 2.3.12 (released 2008-06-04)
3408 ** Merge gnutls_with_netconf branch.
3410 *** libgnutls [PSK]: New API to retrieve PSK identity hint in client.
3411 The function is gnutls_psk_client_get_hint.
3413 *** libgnutls [PSK]: New API to set PSK identity hint in server.
3414 The function is gnutls_psk_set_server_credentials_hint.
3416 *** libgnutls [PSK]: Support server key exchange with PSK identity hint.
3417 In the client, the message is parsed and the application can use
3418 gnutls_psk_client_get_hint to retrieve the hint. In the server, the
3419 message is sent if the application has specified a PSK identity hint
3420 using gnutls_psk_set_server_credentials_hint.
3422 *** libgnutls [PSK]: Support Netconf PSK key derivation.
3423 The function gnutls_psk_netconf_derive_key supports the PSK key
3424 derivation as specified in draft-ietf-netconf-tls-02.txt. New self
3427 *** psktool: Support new --netconf-hint to generate PSK key from password.
3428 Uses the Netconf algorithm to derive PSK key from password.
3430 *** gnutls-serv: Support new --pskhint parameter to set PSK identity hint.
3432 *** gnutls-cli: Always support PSK modes, through a callback.
3433 The callback will derive a PSK key using Netconf algorithm. It will
3434 print the PSK identity hint to help the user.
3436 *** New PSK example client and server.
3437 See doc/examples/ex-client-psk.c and doc/examples/ex-serv-psk.c.
3439 ** libgnutls: Fix gnutls_x509_crl_set_version on arm platforms.
3440 The code didn't work properly on platforms where 'char' is unsigned,
3441 when you set version 0. Reported by Laurence Withers

3454 * Version 2.3.11 (released 2008-05-20)
3456 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3457 The flaw would result in incorrectly terminated sessions with the
3458 error "Decryption has failed" when the server sends a small packet
3459 (typically when the session is closed). Reported by Andreas Metzler

3463 ** Don't use gnulib headers when building C++ library.
3464 Fixes builds under Windows.
3466 ** Make umask a requirement.
3467 We don't know of any system that lacks it, even GNU CoreUtils use it
3470 ** Update gnulib files.

3479 ** Added wide wildcard hostname matching.
3480 Tiny patch by Jean-Philippe Garcia Ballester.
3482 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3483 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3484 which allowed the bugs to be reproduced and fixed easily. Patches
3485 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3486 with more details about these vulnerabilities will be added to

3489 *** [GNUTLS-SA-2008-1-1]
3490 *** libgnutls: Fix crash when sending invalid server name.
3491 The crash can be triggered remotely before authentication, which can
3492 lead to a Daniel of Service attack to disable the server. The bug
3493 cause gnutls to store more session resumption data than what was
3494 allocated for, thus overwriting unallocated memory.
3496 *** [GNUTLS-SA-2008-1-2]
3497 *** libgnutls: Fix crash when sending repeated client hellos.
3498 The crash can be triggered remotely before authentication, which can
3499 lead to a Daniel of Service attack to disable the server. The bug
3500 triggers a null-pointer dereference.
3502 *** [GNUTLS-SA-2008-1-3]
3503 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3504 The crash can be triggered remotely before authentication, which can
3505 lead to a Daniel of Service attack to disable the server. The bug
3506 cause gnutls to read memory beyond the end of the received record.
3508 ** libgnutlsxx: Updated API according to patches from Eduardo
3509 Villanueva Che (discussion at
3510 <http://lists.gnu.org/archive/html/gnutls-devel/2007-02/msg00017.html>)
3512 ** Use umask to restrict permissions to owner before creating a file.

3515 No changes since last version.
3517 * Version 2.3.9 (released 2008-05-16)
3519 ** libgnutls: Fix build failures if SRP/OpenPGP is disabled.
3520 Based on report and tiny patches from
3521 <jared.jennings.ctr@eglin.af.mil>, see
3522 <https://savannah.gnu.org/support/index.php?106342>.
3524 ** libgnutls: Translation fixes.
3526 ** gnutls-cli: Fix so that PSK authentication works.
3527 Also improve manual to give example for gnutls-cli PSK authentication.
3529 ** certtool: Encrypting a private key now require a confirmed password.
3530 Before './certtool -k -8' would merely ask for a password once.
3531 Reported by Daniel 'NebuchadnezzaR' Dehennin
3532 <nebuchadnezzar@asgardr.info> see
3533 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364287>.
3535 ** certtool: When writing private keys to files, change permissions of file.
3536 Now the file which the private key is saved to is chmod'ed 0600.
3537 Reported by martin f krafft <madduck@debian.org> see
3538 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=373169>.
3540 ** guile: Fix -fgnu89-inline test.
3542 ** Removed --enable-profile-mode.
3543 The code linked gnutls with the libfc project (Function Check) which
3544 appears to have been stalled since around 2002.
3546 ** Clean up header file checks by ./configure.
3548 ** Update of gnulib files.
3550 ** API and ABI modifications:
3551 No changes since last version.
3553 * Version 2.3.8 (released 2008-04-29)
3555 ** libgnutls: Increase default handshake packet size limit to 48kb.
3556 The old limit was 16kb and some servers send huge list of trusted CAs,
3557 thus running into the limit. FYI, applications can further increase
3558 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3559 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3560 <marc@mclemente.net> for reporting and providing test servers.
3562 ** libgnutls: Add new error code: GNUTLS_E_HANDSHAKE_TOO_LARGE
3563 Returned when the handshake data size is too large. Before
3564 GNUTLS_E_MEMORY_ERROR was used, which could be confused with other
3567 ** libgnutls: Hide definitions in crypto.h.
3568 We have decided that the APIs defined in crypto.h are not stable
3569 enough for v2.4, so don't use any of those functions.
3571 ** gnutls-cli: exit when hostname doesn't match certificate.
3572 Use --insecure to avoid hostname comparison.
3574 ** certtool: --inder and --outder replaced by --inraw and --outraw.
3575 The reason is to align terminology with OpenPGP, which doesn't use
3576 DER. The old parameters will continue to work for some time.
3578 ** doc: Add section 'Index of new symbols in 2.4.0' to the GTK-DOC manual.
3580 ** doc: Many cosmetic fixes, to silence (most) gtk-doc warnings.
3582 ** Mingw32: Revert libgcrypt vasprintf work-around added in last release.
3583 Use libgcrypt 1.4.1 or later when building on MinGW32, it removes the
3584 vasprintf symbol from the libgcrypt library which caused problems.
3586 ** Update of gnulib files.
3588 ** tests: New self-test of crypto.h RNG code tests/crypto_rng.
3590 ** API and ABI modifications:
3591 GNUTLS_E_HANDSHAKE_TOO_LARGE: ADDED.
3593 * Version 2.3.7 (released 2008-04-21)
3595 ** opencdk now properly sets the key usage bits into openpgp keys.
3597 ** gnutls-cli: Fix crash on TLS handshake failures.
3598 Reported by "Marc F. Clemente" <marc@mclemente.net> in Debian BTS #466477.
3599 This is similar to <http://bugs.debian.org/429183>.
3601 ** certtool: with --generate-request and newly generated keys, print the key.
3603 ** Build fixes for MinGW.
3604 Missing rpl_fseeko symbol in lib/opencdk/. Better checks for linking
3605 with -lws2_32 when needed. Use ASCII only isprint() when printing
3606 X.509 certificate information, to avoid non-ASCII but printable
3607 characters. Thanks to Massimo Gaspari <massimo.gaspari@alice.it> for
3610 ** Update internal copy of libtasn1 to version 1.4.
3612 ** API and ABI modifications:
3613 No changes since last version.
3615 * Version 2.3.6 (released 2008-04-17)
3617 ** Make gnutls_x509_crq_sign2 set certificate request version if not set.
3618 ** Improve documentation for gnutls_x509_crq_sign2.
3619 Based on report from "John Brooks" <aspecialj@gmail.com> in
3620 <http://permalink.gmane.org/gmane.network.gnutls.general/1154>.
3622 ** tests/pathlen: run diff without parameters to improve portability.
3623 Based on HPUX build hints in
3624 <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>.
3626 ** Don't use %e specifier with strftime, it doesn't work under Windows.
3627 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3628 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3630 ** Remove all uses of gnutls_alloca/gnutls_afree.
3631 Use normal gnutls_malloc instead. One reason is increased portability
3632 to Windows, the other is that several of the uses may be unsafe
3633 because the size of data allocated could be large. Reported by
3634 Massimo Gaspari <massimo.gaspari@alice.it> in
3635 <http://permalink.gmane.org/gmane.network.gnutls.general/1170>.
3637 ** Build Guile code with -fgnu89-inline only when supported.
3638 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3639 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3641 ** Several GTK-DOC related fixes.
3643 ** Clean up OpenCDK related code.
3644 GnuTLS now requires its internal OpenCDK code rather than the external
3645 GPL library OpenCDK. Unfortunately, we don't have resources to
3646 maintain an external library (help welcome).
3648 ** API and ABI modifications:
3649 No changes since last version.
3651 * Version 2.3.5 (released 2008-04-14)
3653 ** Build fix for MinGW and --disable-shared.
3654 Reported by Massimo Gaspari <massimo.gaspari@alice.it> in
3655 <http://permalink.gmane.org/gmane.network.gnutls.general/1145>.
3657 ** Document how to generate CRLs.
3658 Suggested by "Rainer Gerhards" <rgerhards@gmail.com>.
3660 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3662 ** Several minor fixes in the OpenPGP interface.
3663 Thanks to Daniel Kahn Gillmor.
3665 ** Fix fopen file descriptor leak in PSK server code.
3666 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3667 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3669 ** Translations files not stored directly in git to avoid merge conflicts.
3671 ** New APIs to let applications replace the RNG used.
3672 Update all RNG callers in the code to use the new interface.
3674 ** Guile code now built with -fgnu89-inline to fix inline semantic problem.
3676 ** Update gnulib files.
3678 ** API and ABI modifications:
3679 gnutls_crypto_rnd_register: ADDED
3680 gnutls_rnd_level_t: ADDED
3681 GNUTLS_RND_KEY: ADDED, gnutls_rnd_level_t member
3682 GNUTLS_RND_RANDOM: ADDED, gnutls_rnd_level_t member
3683 GNUTLS_RND_NONCE: ADDED, gnutls_rnd_level_t member
3684 gnutls_crypto_rnd_st: ADDED
3685 GNUTLS_DIG_SHA224: ADDED
3686 GNUTLS_SIGN_RSA_SHA224: ADDED
3687 gnutls_openpgp_crt_get_auth_subkey: MODIFIED
3689 * Version 2.3.4 (released 2008-03-19)
3691 ** Finish renaming of gnutls_certificate_export_x509_cas etc.
3692 They weren't renamed in the public header file.
3694 ** Added functions to register a cipher/mac/digest. This allows to
3695 override the included ones.
3697 ** Fix a bunch of compiler warnings.
3699 ** API and ABI modifications:
3700 gnutls_crypto_cipher_st: ADDED
3701 gnutls_crypto_mac_st: ADDED
3702 gnutls_crypto_digest_st: ADDED
3703 gnutls_crypto_cipher_register: ADDED
3704 gnutls_crypto_mac_register: ADDED
3705 gnutls_crypto_digest_register: ADDED
3706 GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED
3708 * Version 2.3.3 (released 2008-03-10)
3710 ** Fix build failure in libextra/gnutls_extra.c that needed opencdk.h.
3711 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
3713 ** No longer compiled using -D_REENTRANT -D_THREAD_SAFE.
3714 We could not find any modern justification for enabling these flags by
3715 default. If you know of some platform that needs one of the flags to
3716 work properly, please let us know. (Actually introduced in v2.3.0 but
3717 not documented until now.)
3719 ** Importing many CA certificates are now considerably faster.
3720 This affect gnutls_certificate_set_x509_trust_mem,
3721 gnutls_certificate_set_x509_trust, and
3722 gnutls_certificate_set_x509_trust_file. The complexity was reduced
3723 from O(2*n^2) to O(n). When adding 206 files containing 408
3724 certificates, using gnutls_certificate_set_x509_trust_file, the time
3725 dropped from 40 seconds to 0.3 seconds. Thanks to Edgar Fuß for code
3726 to trigger the problem. See also
3727 <http://blog.josefsson.org/2008/02/27/real-world-performance-tuning-with-callgrind/>.
3729 ** Clarify documentation for gnutls_x509_crt_set_subject_alternative_name
3730 ** to be explicit that it takes zero terminated data.
3732 ** gnutls-cli --print-cert now print PKCS#3 format Diffie-Hellman parameters.
3734 ** Documentation fixes for the GTK-DOC manual.
3736 ** Fix compilation error related to __FUNCTION__ on some systems.
3737 Reported by Tim Mooney, see
3738 <https://savannah.gnu.org/support/?106267>.
3740 ** Updated translations.
3742 ** Update gnulib files.
3744 ** API and ABI modifications:
3745 gnutls_hex2bin: MODIFIED, uses size_t instead of int for string length,
3746 and char* instead of void* for output buffer.
3748 * Version 2.3.2 (released 2008-02-26)
3750 ** Fix srcdir!=objdir failure in openpgpself test.
3752 ** Improved API documentation output from GTK-DOC.
3754 ** Added gnutls_x509_dn_export(). Patch by Joe Orton.
3756 ** Renamed gnutls_certificate_export_x509_cas and friends.
3757 See <http://lists.gnu.org/archive/html/gnutls-devel/2008-02/msg00043.html>.
3759 ** Internal header files cleanup.
3761 ** API and ABI modifications:
3762 gnutls_certificate_export_x509_cas: RENAMED to gnutls_certificate_get_x509_cas
3763 gnutls_certificate_export_x509_crls: RENAMED to gnutls_certificate_get_x509_crls
3764 gnutls_certificate_export_openpgp_keyring: RENAMED to gnutls_certificate_get_openpgp_keyring
3765 gnutls_x509_dn_export: ADDED
3767 * Version 2.3.1 (released 2008-02-21)
3769 ** OpenPGP support merged into libgnutls and is now licensed under LGPL.
3770 The included copy of OpenCDK has been stripped down and re-licensed
3773 ** Cipher priority string handling now handle strings that starts with NULL.
3774 Thanks to Laurence Withers <l@lwithers.me.uk>.
3776 ** gnutls-cli: When -d is used, also prints RNG information from libgcrypt.
3778 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3781 ** Increased the default certificate verification chain limits and allowed
3782 for checks without limitation.
3784 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3785 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3786 strings and return the proper size.
3788 ** Add section 'On Record Padding' to the manual.
3789 This collects all problems related to record padding with
3790 Nokia/Sony-Ericsson phones that we know about.
3792 ** Several improvements in the OpenPGP authentication.
3793 Now subkeys can be used for authentication, according to
3794 draft-mavrogiannopoulos-rfc5081bis-00.txt.
3796 ** certtool can print information on OpenPGP certificates and keys.
3798 ** Added gnutls_x509_dn_import/init/deinit() to access raw DER DN.
3801 ** Added gnutls_certificate_export_x509_cas and other functions to
3802 export elements from the certificate credentials structure. Based on
3803 suggestion from Joe Orton.
3806 Clarify that srp_base64 is not the same as normal base64.
3808 ** Fix non-portable use of brace expansion in makefiles.
3810 ** API and ABI modifications:
3811 gnutls_certificate_export_x509_cas: ADDED
3812 gnutls_certificate_export_x509_crls: ADDED
3813 gnutls_certificate_export_openpgp_keyring: ADDED
3814 gnutls_openpgp_keyid_t: ADDED, instead of hard-coded 'unsigned char[8]'.
3815 gnutls_openpgp_crt_get_key_id: ADDED, obsoletes gnutls_openpgp_crt_get_id.
3816 gnutls_openpgp_crt_get_revoked_status: ADDED
3817 gnutls_openpgp_crt_get_subkey_count: ADDED
3818 gnutls_openpgp_crt_get_subkey_idx: ADDED
3819 gnutls_openpgp_crt_get_subkey_revoked_status: ADDED
3820 gnutls_openpgp_crt_get_subkey_pk_algorithm: ADDED
3821 gnutls_openpgp_crt_get_subkey_creation_time: ADDED
3822 gnutls_openpgp_crt_get_subkey_expiration_time: ADDED
3823 gnutls_openpgp_crt_get_subkey_id: ADDED
3824 gnutls_openpgp_crt_get_subkey_usage: ADDED
3825 gnutls_openpgp_privkey_get_fingerprint: ADDED
3826 gnutls_openpgp_privkey_get_key_id: ADDED

3835 gnutls_openpgp_crt_get_subkey_pk_dsa_raw: ADDED
3836 gnutls_openpgp_crt_get_subkey_pk_rsa_raw: ADDED
3837 gnutls_openpgp_crt_get_pk_dsa_raw: ADDED

3852 GNUTLS_CRT_PRINT_ONELINE: ADDED, same as old GNUTLS_X509_CRT_ONELINE.
3853 GNUTLS_CRT_PRINT_UNSIGNED_FULL: ADDED, same as
3854 old GNUTLS_X509_CRT_UNSIGNED_FULL.
3856 * Version 2.3.0 (released 2008-01-08)
3858 ** LZO compression is now disabled by default.
3859 The reason is that LZO compression is not standardized in TLS. If you
3860 wish to experiment with it, you will have to supply --with-lzo when
3861 invoking ./configure. The internal copy of minilzo is no longer
3862 included with GnuTLS, so you will need to install liblzo or liblzo2 on
3863 your system to have --with-lzo to be effective.
3865 ** More than one server name field is now sent to the server properly.
3866 Thanks to mark.phillips@virgin.net.
3868 ** Fixes the post_client_hello_function(). The extensions are now parsed
3869 in a callback friendly way.
3871 ** Fix for certificate selection in servers with certificate callbacks.
3873 ** Updated translations.
3875 ** Update gnulib files.
3877 ** API and ABI modifications:
3878 No changes since last version.
3880 * Version 2.2.5 (released 2008-05-19)
3882 ** Fix flaw in fix for GNUTLS-SA-2008-1-3.
3883 The flaw would result in incorrectly terminated sessions with the
3884 error "Decryption has failed" when the server sends a small packet
3885 (typically when the session is closed). Reported by Andreas Metzler
3886 <ametzler@downhill.at.eu.org> in
3887 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2807>.
3889 ** API and ABI modifications:
3890 No changes since last version.
3892 * Version 2.2.4 (released 2008-05-19)
3894 ** Fix three security vulnerabilities. [GNUTLS-SA-2008-1]
3895 Thanks to CERT-FI for finding the bugs and providing detailed reports,
3896 which allowed the bugs to be reproduced and fixed easily. Patches
3897 developed by Simon Josefsson and Nikos Mavrogiannopoulos. Any updates
3898 with more details about these vulnerabilities will be added to
3899 <http://www.gnu.org/software/gnutls/security.html>
3901 *** [GNUTLS-SA-2008-1-1]
3902 *** libgnutls: Fix crash when sending invalid server name.
3903 The crash can be triggered remotely before authentication, which can
3904 lead to a Daniel of Service attack to disable the server. The bug
3905 cause gnutls to store more session resumption data than what was
3906 allocated for, thus overwriting unallocated memory.
3908 *** [GNUTLS-SA-2008-1-2]
3909 *** libgnutls: Fix crash when sending repeated client hellos.
3910 The crash can be triggered remotely before authentication, which can
3911 lead to a Daniel of Service attack to disable the server. The bug
3912 triggers a null-pointer dereference.
3914 *** [GNUTLS-SA-2008-1-3]
3915 *** libgnutls: Fix crash in cipher padding decoding for invalid record lengths.
3916 The crash can be triggered remotely before authentication, which can
3917 lead to a Daniel of Service attack to disable the server. The bug
3918 cause gnutls to read memory beyond the end of the received record.
3920 ** API and ABI modifications:
3921 No changes since last version.
3923 * Version 2.2.3 (released 2008-05-06)
3925 ** Increase default handshake packet size limit to 48kb.
3926 The old limit was 16kb and some servers send huge list of trusted CAs,
3927 thus running into the limit. FYI, applications can further increase
3928 this limit using gnutls_handshake_set_max_packet_length. Thanks to
3929 Marc Haber <mh+debian-bugs@zugschlus.de> and "Marc F. Clemente"
3930 <marc@mclemente.net> for reporting and providing test servers.
3932 ** Fix compilation error related to __FUNCTION__ on some systems.
3933 Reported by Tim Mooney, see
3934 <https://savannah.gnu.org/support/?106267>.
3936 ** Documented the --priority option to gnutls-cli and gnutls-serv.
3938 ** Fix fopen file descriptor leak in PSK server code.
3939 Thanks to Laurence Withers <l@lwithers.me.uk>, see
3940 <http://lists.gnu.org/archive/html/gnutls-devel/2008-04/msg00002.html>.
3942 ** Build Guile code with -fgnu89-inline only when supported.
3943 Reported by Kris Karas <ktk@enterprise.bidmc.harvard.edu> in
3944 <http://permalink.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2708>.
3946 ** Make Camellia encryption work.
3947 Reported by Yoshisato YANAGISAWA <yanagisawa@csg.is.titech.ac.jp> in
3948 <http://thread.gmane.org/gmane.comp.encryption.gpg.gnutls.devel/2746>.
3950 ** API and ABI modifications:
3951 No changes since last version.
3953 * Version 2.2.2 (released 2008-02-21)
3955 ** Cipher priority string handling now handle strings that starts with NULL.
3956 Thanks to Laurence Withers <l@lwithers.me.uk>.
3958 ** Corrected memory leaks in session resuming and DHE ciphersuites. Reported
3961 ** Increased the default certificate verification chain limits and allowed
3962 for checks without limitation.
3964 ** Corrected the behaviour of gnutls_x509_crt_get_subject_alt_name()
3965 and gnutls_x509_crt_get_subject_alt_name() to not null terminate binary
3966 strings and return the proper size.
3968 ** API and ABI modifications:
3969 No changes since last version.
3971 * Version 2.2.1 (released 2008-01-17)
3973 ** Prevent linking libextra against previously installed libgnutls.
3974 Tiny patch from "Alon Bar-Lev" <alon.barlev@gmail.com>, see
3975 <http://bugs.gentoo.org/show_bug.cgi?id=202269>.
3977 ** Fixes the post_client_hello_function(). The extensions are now parsed
3978 in a callback friendly way.
3980 ** Fix for certificate selection in servers with certificate callbacks.
3982 ** API and ABI modifications:
3983 No changes since last version.
3985 * Version 2.2.0 (released 2007-12-14)
3987 ** Update internal copy of libtasn1 to version 1.2.
3989 ** Certtool --verify-chain now handle inputs larger than 64kb.
3990 This fixes the self-test "rsa-md5-collision" under MinGW+Wine with
3991 recent versions of libgcrypt. The problem was that Wine with the
3992 libgcrypt RNG generates huge amounts of debugging output.
3994 ** Translation updates.
3995 Added Dutch translation. Updated Polish and Swedish translation.
3997 ** Major changes compared to the v2.0 branch:
3999 *** SRP support aligned with newly published RFC 5054.
4001 *** OpenPGP support aligned with newly published RFC 5081.
4003 *** Support for DSA2 keys.
4005 *** Support for Camellia cipher.
4007 *** Support for Opaque PRF Input extension.
4009 *** PKCS#8 parser now handle DSA keys.
4011 *** Change from GPLv2 to GPLv3 for command-line tools, libgnutls-extra, etc.
4012 Notice that liblzo2 2.02 is licensed under GPLv2 only. Earlier
4013 versions, such as 2.01 which is included with GnuTLS, is available
4014 under GPLv2 or later. If this incompatibility causes problems, we
4015 recommend you to disable LZO using --without-lzo. LZO compression is
4016 not a standard TLS compression algorithm, so the impact should be
4019 *** Functions for disabling record protocol padding.
4020 Works around bugs on Nokia/Ericsson phones.
4022 *** New functions gnutls_priority_set() for setting cipher priorities easily.
4023 Priorities like "COMPAT" also enables other work arounds, such as
4026 *** Other minor improvements and bug fixes.
4028 ** Backwards incompatible API/ABI changes in GnuTLS 2.2
4029 To adapt to changes in the TLS extension specifications for OpenPGP
4030 and SRP, the GnuTLS API had to be modified. This means breaking the
4031 API and ABI backwards compatibility. That is something we try to
4032 avoid unless it is necessary. We decided to also remove the already
4033 deprecated stub functions for X.509 to XML conversion and TLS
4034 authorization (see below) when we had the opportunity.
4036 Generally, most applications does not need to be modified. Just
4037 re-compile them against the latest GnuTLS release, and it should work
4040 Applications that use the OpenPGP or SRP features needs to be
4041 modified. Below is a list of the modified APIs and discussion of what
4042 the minimal things you need to modify in your application to make it
4043 work with GnuTLS 2.2.
4045 Note that GnuTLS 2.2 also introduces new APIs -- such as
4046 gnutls_set_priority() that is superior to
4047 gnutls_set_default_priority() -- that you may want to start using.
4048 However, using those new APIs is not required to use GnuTLS 2.2 since
4049 the old functions continue are still supported. This text only
4050 discuss what you minimally have to modify.
4052 *** XML related changes
4053 The function `gnutls_x509_crt_to_xml' has been removed. It has been
4054 deprecated and only returned an error code since GnuTLS version
4055 1.2.11. Nobody has complained, so users doesn't seem to miss the
4056 functionality. We don't know of any other library to convert X.509
4057 certificates into XML format, but we decided (long ago) that GnuTLS
4058 isn't the right place for this kind of functionality. If you want
4059 help to find some other library to use here, please explain and
4060 discuss your use case on help-gnutls@gnu.org.
4062 *** TLS Authorization related changes
4063 Everything related to TLS authorizations have been removed, they were
4064 only stub functions that returned an error code:
4066 GNUTLS_SUPPLEMENTAL_AUTHZ_DATA
4067 gnutls_authz_data_format_type_t
4068 gnutls_authz_recv_callback_func
4069 gnutls_authz_send_callback_func
4071 gnutls_authz_send_x509_attr_cert
4072 gnutls_authz_send_saml_assertion
4073 gnutls_authz_send_x509_attr_cert_url
4074 gnutls_authz_send_saml_assertion_url
4076 *** SRP related changes
4077 The callback gnutls_srp_client_credentials_function has a new
4078 prototype, and its semantic has changed. You need to rewrite the
4079 callback, see the updated function documentation and SRP example code
4080 (doc/examples/ex-client-srp.c and doc/examples/ex-serv-srp.c) for more
4083 The alert codes GNUTLS_A_MISSING_SRP_USERNAME and
4084 GNUTLS_A_UNKNOWN_SRP_USERNAME are no longer used by the SRP
4085 specification, instead the GNUTLS_A_UNKNOWN_PSK_IDENTITY alert is
4086 used. There are #define's to map the old names to the new. You may
4087 run into problems if you have a switch-case with cases for both SRP
4088 alerts, since they are now mapped to the same value. The solution is
4089 to drop the SRP alerts from such switch cases, as they are now
4090 deprecated in favor of GNUTLS_A_UNKNOWN_PSK_IDENTITY.
4092 *** OpenPGP related changes
4093 The function `gnutls_certificate_set_openpgp_keyserver' have been
4094 removed. There is no replacement functionality inside GnuTLS. If you
4095 need keyserver functionality, consider using the GnuPG tools.
4097 All functions, types, and error codes related to OpenPGP trustdb
4098 format have been removed. The trustdb format is a non-standard
4099 GnuPG-specific format, and we recommend you to use key rings instead.
4100 The following have been removed:
4102 gnutls_certificate_set_openpgp_trustdb
4103 gnutls_openpgp_trustdb_init
4104 gnutls_openpgp_trustdb_deinit
4105 gnutls_openpgp_trustdb_import
4106 gnutls_openpgp_key_verify_trustdb
4107 gnutls_openpgp_trustdb_t
4108 GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED
4110 The following functions has an added parameter of the (new) type
4111 `gnutls_openpgp_crt_fmt_t'. The type specify the format of the data
4112 (binary or base64). The functions are:
4113 gnutls_certificate_set_openpgp_key_file
4114 gnutls_certificate_set_openpgp_key_mem
4115 gnutls_certificate_set_openpgp_keyring_mem
4116 gnutls_certificate_set_openpgp_keyring_file
4118 To improve terminology and align with the X.509 interface, some
4119 functions have been renamed. Compatibility mappings exists. The old
4120 and new names of the affected functions and types are:
4123 gnutls_openpgp_key_t gnutls_openpgp_crt_t
4124 gnutls_openpgp_key_fmt_t gnutls_openpgp_crt_fmt_t
4125 gnutls_openpgp_key_status_t gnutls_openpgp_crt_status_t
4126 GNUTLS_OPENPGP_KEY GNUTLS_OPENPGP_CERT
4127 GNUTLS_OPENPGP_KEY_FINGERPRINT GNUTLS_OPENPGP_CERT_FINGERPRINT
4128 gnutls_openpgp_key_init gnutls_openpgp_crt_init
4129 gnutls_openpgp_key_deinit gnutls_openpgp_crt_deinit
4130 gnutls_openpgp_key_import gnutls_openpgp_crt_import
4131 gnutls_openpgp_key_export gnutls_openpgp_crt_export
4132 gnutls_openpgp_key_get_key_usage gnutls_openpgp_crt_get_key_usage
4133 gnutls_openpgp_key_get_fingerprint gnutls_openpgp_crt_get_fingerprint
4134 gnutls_openpgp_key_get_pk_algorithm gnutls_openpgp_crt_get_pk_algorithm
4135 gnutls_openpgp_key_get_name gnutls_openpgp_crt_get_name
4136 gnutls_openpgp_key_get_version gnutls_openpgp_crt_get_version
4137 gnutls_openpgp_key_get_creation_time gnutls_openpgp_crt_get_creation_time
4138 gnutls_openpgp_key_get_expiration_time gnutls_openpgp_crt_get_expiration_time
4139 gnutls_openpgp_key_get_id gnutls_openpgp_crt_get_id
4140 gnutls_openpgp_key_check_hostname gnutls_openpgp_crt_check_hostname
4141 gnutls_openpgp_send_key gnutls_openpgp_send_cert
4143 ** API and ABI modifications:
4144 No changes since last version.
4146 * Version 2.1.8 (released 2007-12-10)
4148 ** The GPL version has been changed from version 2 to version 3.
4149 This affects the self-tests, command-line tools, the libgnutls-extra
4150 library, the relevant guile parts, and the build environment.
4152 ** Added gnutls_x509_crt_get_subject_alt_name2().
4154 ** Corrected a segfault when setting an empty gnutls_priority_t
4155 at gnutls_priority_set().
4157 ** Use gettext 0.17 which updates m4/lib-*.m4 macros.
4158 Fixes a problem with spurious -L/usr/lib additions.
4160 ** API and ABI modifications:
4161 gnutls_x509_crt_get_subject_alt_name2: ADD.
4163 * Version 2.1.7 (released 2007-11-29)
4165 ** PKCS #8 parser can now encode/decode DSA keys.
4167 ** Updated gnutls_set_default_priority2() now renamed to
4168 gnutls_priority_set() and gnutls_priority_set_direct() which
4169 accept a string to indicate preferences of ciphersuite parameters.
4171 ** gnutls-cli and gnutls-serv now have a --priority option to set
4172 the priority string.
4174 ** The gnutls_*_convert_priority() functions were deprecated by
4175 the gnutls_priority_set() and gnutls_priority_set_direct().
4177 ** Internal copy of OpenCDK upgraded to version 0.6.6.
4179 ** API and ABI modifications:
4180 gnutls_priority_init: ADD.
4181 gnutls_priority_deinit: ADD.
4182 gnutls_priority_set: ADD.
4183 gnutls_priority_set_direct: ADD.

4191 gnutls_set_default_priority: UNDEPRECATED
4192 gnutls_set_default_priority_export: UNDEPRECATED
4194 ** Undocumented API and ABI modifications earlier in the 2.1.x series:
4195 GNUTLS_CIPHER_UNKNOWN: ADD.
4196 GNUTLS_CIPHER_CAMELLIA_128_CBC: ADD.
4197 GNUTLS_CIPHER_CAMELLIA_256_CBC: ADD.

4208 gnutls_certificate_send_x509_rdn_sequence: ADD prototype to gnutls.h.in.
4210 * Version 2.1.6 (released 2007-11-15)
4212 ** Corrected bug in decompression of expanded compression data.
4214 ** Added the --to-p8 option to certtool to convert private keys
4217 ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code.
4219 ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted
4222 ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM.
4223 During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code
4224 was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being
4225 documented. This caused some problems (e.g., debian #450854). To
4226 avoid backwards compatibility problems, this release revert this
4227 change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has
4228 done in GnuTLS 2.0.x and earlier, and add a new error code
4229 GNUTLS_E_UNKNOWN_ALGORITHM.
4231 ** Fixes several gtk-doc warnings.
4233 ** API and ABI modifications:
4234 GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED.
4235 GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED.
4236 GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD.
4238 * Version 2.1.5 (released 2007-11-01)
4240 ** Fix PKCS#3 parameter export problem.
4242 ** Improve certtool queries, they now print the default value.
4246 ** Update gnulib files.
4248 ** API and ABI modifications:
4249 No changes since last version.
4251 * Version 2.1.4 (released 2007-10-27)
4253 ** Added the --v1 option to certtool, to allow generating X.509
4254 version 1 certificates.
4256 ** certtool: Add option --disable-quick-random to enable the old behaviour
4257 of using /dev/random to generate keys.
4259 ** Added priority functions that accept strings.
4261 ** Added gnutls_set_default_priority2() which accepts a flag to indicate
4262 priorities preferences.
4264 ** Added gnutls_record_disable_padding() to allow servers talking to
4265 buggy clients that complain if the TLS 1.0 record protocol padding is
4268 ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling
4269 all supported compatibility options (like disabling padding).
4271 ** The gnutls_certificate_set_openpgp_* functions were modified to include
4272 the format. This makes the interface consistent with the x509 functions.
4274 ** Internal copy of OpenCDK upgraded to version 0.6.5.
4276 ** Update gnulib files.

4313 * Version 2.1.3 (released 2007-10-17)
4315 ** TLS authorization support removed.
4316 This technique may be patented in the future, and it is not of crucial
4317 importance for the Internet community. After deliberation we have
4318 concluded that the best thing we can do in this situation is to
4319 encourage society not to adopt this technique. We have decided to
4320 lead the way with our own actions.
4322 ** Re-enabled the 256 bit ciphers in the default priorities.

4337 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4338 gnutls_supplemental_data_format_type_t enum type becomes empty.
4340 * Version 2.1.2 (released 2007-10-14)
4342 ** Removed all the trustdb code from openpgp authentication.
4343 We now use only the well-specified keyrings.
4345 ** The 256 bit ciphers are not enabled in the default priorities.
4347 ** Added support for DSA2 using libgcrypt 1.3.0.
4349 ** certtool: Fixed data corruption when using --outder.
4351 ** Removed all the xml related stubs and functions.
4353 ** Added capability to set a callback after the client hello is received
4354 by the server in order to adjust parameters before the handshake.
4356 ** SRP was corrected to adhere to the latest draft (published soon as RFC)
4358 ** Corrected bug which did not allow a server to run without supporting

4382 * Version 2.1.1 (released 2007-09-24)
4384 ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA.
4385 Camellia is only enabled in GnuTLS if the installed libgcrypt has been
4386 compiled with Camellia support. See the libgcrypt documentation on
4387 how to enable it. Unconditionally disable it using the configure
4388 option --disable-camellia. Fixes #1.
4390 ** Properly document in the NEWS file the API change in the last release.
4392 ** API and ABI modifications:
4393 No changes since last version.
4395 * Version 2.1.0 (released 2007-09-20)
4397 ** Support for draft-rescorla-tls-opaque-prf-input-00.txt.
4398 The support is disabled by default. Since no value has been allocated
4399 by the IANA for this extension yet, you will need to provide one
4400 yourself by invoking './configure --enable-opaque-prf-input=42'.
4403 ** Example code: Fix compilation flaw under MinGW.
4405 ** API and ABI modifications:
4406 gnutls_oprfi_callback_func: ADD, new typedef function prototype.
4407 gnutls_oprfi_enable_client: ADD, new function.
4408 gnutls_oprfi_enable_server: ADD, new function.

4437 * Version 2.0.2 (released 2007-10-17)
4439 ** TLS authorization support removed.
4440 This technique may be patented in the future, and it is not of crucial
4441 importance for the Internet community. After deliberation we have
4442 concluded that the best thing we can do in this situation is to
4443 encourage society not to adopt this technique. We have decided to
4444 lead the way with our own actions.
4446 ** certtool: Fixed data corruption when using --outder.
4448 ** Fix configure-time Guile detection.
4450 ** API and ABI modifications:
4451 GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the
4452 gnutls_supplemental_data_format_type_t enum type becomes empty.
4454 * Version 2.0.1 (released 2007-09-20)
4456 ** New directory doc/credentials/ with test credentials.
4457 This collects the test credentials from the web page and from src/.
4458 The script gnutls-http-serv has also been moved to that directory.
4460 ** Update SRP extension type and cipher suite with official IANA values.
4461 This breaks backwards compatibility with SRP in older versions of
4462 GnuTLS, but this is intentional to speed up the adoption of the
4463 official values. The old values we used were incorrect.
4465 ** Guile: Fix `x509-certificate-dn-oid'
4467 ** API and ABI modifications:
4468 No changes since last version.
4470 * Version 2.0.0 (released 2007-09-04)
4472 ** Included copy of Libtasn1 upgraded to version 1.1.
4474 ** Disable building of some examples if anonymous ciphers are disabled.
4476 ** Don't build examples for disabled features.
4478 ** API and ABI modifications:
4479 No changes since last version.
4481 * Version 1.7.19 (released 2007-08-27)
4483 ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical.
4484 This solves connection problems in mutt, see
4485 <http://bugs.debian.org/439640>.
4487 ** Update gnulib files.
4488 In particular, the getpass module -- with its dependencies on getline,
4489 getdelim, fseeko etc -- where moved from the lgl/ (used by the core
4490 library) directory to the gl/ directory (only used by the command line
4491 tools). The reason is that getpass is now only used by the
4492 command-line tools, and reducing the number of gnulib modules linked
4493 to the core library helps portability and reduces size.
4497 ** Disable building of PGP examples if PGP is disabled.
4499 ** Included copy of OpenCDK upgraded to version 0.6.4.
4501 ** API and ABI modifications:
4502 No changes since last version.
4504 * Version 1.7.18 (released 2007-08-16)
4506 ** Install images for the info manual.
4507 This has a side effect of renaming the images. See
4508 <http://thread.gmane.org/gmane.comp.tex.texinfo.bugs/3533> for
4509 discussions on the approach chosen.
4511 ** Fix pointer mix to variables of different size.
4512 Patch extracted from
4513 <http://cvs.fedora.redhat.com/viewcvs/devel/gnutls/gnutls-1.6.3-incompat-pointers.patch?rev=1.1&view=auto>.
4515 ** Fix warnings during build.
4516 Thanks to Andreas Metzler <ametzler@downhill.at.eu.org>.
4518 ** API and ABI modifications:
4519 No changes since last version.
4521 * Version 1.7.17 (released 2007-08-15)
4523 ** New functions to perform external signing.
4524 Set the signing callback function (of the gnutls_sign_func prototype)
4525 using the gnutls_sign_callback_set function. In the callback, you may
4526 find the new functions gnutls_x509_privkey_sign_hash and
4527 gnutls_openpgp_privkey_sign_hash useful. A new function
4528 gnutls_sign_callback_get is also added, to retrieve the function
4529 pointer. Thanks to "Alon Bar-Lev" <alon.barlev@gmail.com> for
4530 comments and testing.
4532 ** New self test of client and server authenticated X.509 TLS sessions.
4533 See tests/x509self.c and tests/x509signself.c. The latter also tests
4534 the new external signing callback interface.
4536 ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX.
4537 These two actually describe the outer limits of a range of error codes
4538 reserved to the application. All of the errors are treated as fatal
4539 by the library (it has to since it doesn't know the semantics of the
4540 error codes). This can be useful in callbacks, to signal some
4541 application-specific error condition, which will usually eventually
4542 cause some gnutls API to return the same error code as the callback,
4543 which then can be inspected by the application. Note that error codes
4546 ** gnutls_set_default_priority now disable TLS 1.2 by default.
4547 The RFC is not released yet, and we're approaching a major release so
4548 let's not enable it just yet.
4550 ** Fix namespace so that gnutls_*_t is used consistently.
4551 Before, many places in the GnuTLS code used the old deprecated type
4552 names without the '_t' suffix.
4554 ** Build fixes for Guile code.
4555 Patch from Ludovic Courtes <ludovic.courtes@laas.fr>.
4557 ** More documentation fixes.
4558 In particular, the section headings were modified for casing. By
4559 Ludovic Courtes <ludovic.courtes@laas.fr>.
4561 ** Updated Polish and Swedish translations.
4562 Thanks to Jakub Bogusz <qboosh@pld-linux.org> and Daniel Nylander
4563 <po@danielnylander.se>.
4565 ** API and ABI modifications:
4566 gnutls_sign_func: ADD, new type for sign callback.
4567 gnutls_sign_callback_set: ADD, new function to set sign callback.
4568 gnutls_sign_callback_get: ADD, new function to retrieve sign callback.
4569 gnutls_x509_privkey_sign_hash,
4570 gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback.
4571 GNUTLS_E_APPLICATION_ERROR_MIN,
4572 GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes.
4574 * Version 1.7.16 (released 2007-08-07)
4576 ** Fix sanity checks and return values in certificate selection.
4577 In some cases, GnuTLS omitted to report suitable error codes when no
4578 suitable certificate was found.
4580 ** Fix gnutls-cli starttls EOF on Mac OS X.
4581 Thanks to Hal Eden <n.mavrogiannopoulos@gmail.com>.
4583 ** Documentation fixes.
4584 In particular, the section headings were modified for casing. By

4590 No changes since last version.
4592 * Version 1.7.15 (released 2007-07-02)
4594 ** Fix self-tests key-id under mingw32.
4596 ** Test that the Guile header files are recent enough to work.
4597 Before we just tested that the command line tool 'guile' was recent
4598 enough, which may not be sufficient if you still have an old
4599 libguile.h header installed.
4601 ** Guile bindings are now installed under $prefix by default.
4602 Use --without-guile-site-dir to install it under $pkgdatadir/site/
4603 where $pkgdatadir is as returned by "guile-config info pkgdatadir".
4604 Use --with-guile-site-dir=/your/own/path to specify the path manually.
4605 The default, --with-guile-site-dir, will install the Guile bindings
4606 under $datadir/guile/site. There is a new section 'Guile
4607 Preparations' in the manual that discuss these issues.
4609 ** Fix run-time library path ordering in linking the Guile bindings.
4611 ** Improved manual on downloading, installing, getting help, bug reports etc.
4612 Suggested by Ludovic Courtès <ludovic.courtes@laas.fr>.
4614 ** Add Malay message translations.

4688 No changes since last version.
4690 * Version 1.7.11 (released 2007-05-26)
4692 ** Include opencdk.h in the release.
4693 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
4695 ** API and ABI modifications:
4696 No changes since last version.
4698 * Version 1.7.10 (released 2007-05-25)
4700 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
4701 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>.
4703 ** Update of gnulib files.
4705 ** GnuTLS is now developed in GIT instead of CVS.
4706 See <http://repo.or.cz/w/gnutls.git> for a public repository.
4708 ** API and ABI modifications:
4709 gnutls_x509_crt_get_raw_issuer_dn: ADD.
4710 gnutls_x509_crt_get_raw_dn: ADD.
4712 * Version 1.7.9 (released 2007-05-12)
4714 ** X.509 certificates are preferred over OpenPGP keys.
4715 This is a change in the semantics of gnutls_set_default_priority.
4717 ** The included copy of OpenCDK has been updated to 0.6.1.
4718 There has been some API changes in OpenCDK, and the GnuTLS layer have
4719 been modified as well. Note that while there are API/ABI incompatible
4720 changes in OpenCDK, this does not influence GnuTLS's API/ABI because
4721 its API/ABI have not changed. From this version on, GnuTLS requires
4722 OpenCDK 0.6.0 or later.
4724 ** Fix build failure caused by missing doc/gnutls-logo.pdf.
4726 ** Change certtool's default serial number from 0 to a time-based value.
4728 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
4729 Before, we remove the parameters field, which resulted in a slightly
4730 different DER encoding which in turn caused signature verification
4731 failures of GnuTLS-generated RSA certificates in some other
4732 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
4733 you read, this may or may not be correct, but our new behaviour appear
4734 to be consistent with other widely used implementations.
4736 ** Fix mem leaks in gnutls_x509_crt_print.
4738 ** API and ABI modifications:
4739 No changes since last version.
4741 * Version 1.7.8 (released 2007-04-16)
4743 ** Added examples for the authorization extension.
4744 See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c.
4746 ** The examples only use gnutls_set_default_priority().
4747 The exception is when DH_ANON is needed.
4749 ** Improve gnutls_set_default_priority() priorities.
4750 The new approach is for it to try and negotiate all secure and
4751 standard mechanisms available. Currently, DH_ANON ciphersuites and
4752 LZO compressions are not enabled by default, because they are,
4753 respectively, insecure and non-standardized. Note that TLS 1.2 will
4754 not be enabled by default in non-experimental release until it has
4755 been approved by the IETF.
4757 ** gnutls-cli and gnutls-serv now uses the library's default priorities.
4758 This means that to get DH_ANON and LZO compression, you'll need to
4759 specify that manually using '--kx anon' or '--comp lzo'.
4761 ** Minor fixes to the human display format of X.509 certificates.
4763 ** New APIs to extract Distinguished Name's from X.509 certificates.
4764 Based on patch from Howard Chu <hyc@symas.com>.
4766 ** Improved library searching for opencdk.
4767 It will now add the appropriate -R or -Wl,-rpath flags as necessary.
4768 The deprecated opencdk.m4 is no longer used.
4770 ** New APIs to list supported algorithms in the library.
4771 The APIs are gnutls_cipher_list, gnutls_mac_list,
4772 gnutls_compression_list, gnutls_protocol_list,
4773 gnutls_certificate_type_list, gnutls_kx_list, and
4774 gnutls_cipher_suite_info. Suggested by Howard Chu <hyc@symas.com>.
4776 ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys.
4778 ** New configure option --disable-tls-authorization to disable tls-authz.
4780 ** Fix prototype for `gnutls_psk_set_client_credentials'.
4781 The last parameter was renamed from 'flags' to 'format' and the type
4782 changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type),
4783 which shouldn't cause any ABI changes. Reported by ludo@chbouib.org
4786 ** Fix allocation in gnutls_certificate_set_openpgp_key.
4787 Tiny patch from ludo@chbouib.org (Ludovic Courtès).
4789 ** API and ABI modifications:
4790 gnutls_x509_dn_t: ADD.
4791 gnutls_x509_ava_st: ADD.
4792 gnutls_x509_crt_get_subject,
4793 gnutls_x509_crt_get_issuer: ADD.
4794 gnutls_x509_dn_get_rdn_ava: ADD.
4795 gnutls_cipher_list: ADD.
4796 gnutls_mac_list: ADD.
4797 gnutls_compression_list: ADD.
4798 gnutls_protocol_list: ADD.
4799 gnutls_certificate_type_list: ADD.
4800 gnutls_kx_list: ADD.
4801 gnutls_cipher_suite_info: ADD.
4803 * Version 1.7.7 (released 2007-02-22)
4805 ** Support for supplemental handshake messages and authorization data.
4806 Supplemental data is described in RFC 4680 and the authorization
4807 extensions in draft-housley-tls-authz-extns-07.
4809 ** Support for authorization data in gnutls-cli and gnutls-serv.
4810 New parameters --authz-x509-attr-cert and --authz-saml-assertion.
4812 ** Fix for gnutls_x509_crt_check_hostname.
4813 Before it would have reported that the certificate matched a hostname
4814 when it did not have any dNSName or any CN field. Report and tiny
4815 patch from "Richard W.M. Jones" <rjones@redhat.com>.
4817 ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname.
4818 Tests regressions of the bug, and several other features.
4820 ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's.
4821 Before there were no support for iPAddress SAN's during comparison.
4823 ** New API to print information about CRL's.
4824 The function is gnutls_x509_crl_print.
4826 ** New API to extract signature value from CRL's.
4827 The function is gnutls_x509_crl_get_signature.
4829 ** Support for directoryName Subject Alternative Name's.
4830 The gnutls_x509_crt_get_subject_alt_name function returns the DN as a
4831 string in the provided buffer.
4833 ** Internal improvements to certtool.
4834 It uses gnutls_x509_crl_print to print CRL information. It uses some
4835 more gnulib modules to simplify error handling.
4837 ** API and ABI modifications:
4838 GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element.
4839 gnutls_supplemental_data_format_type_t: ADD.
4840 gnutls_authz_data_format_type_t: ADD.
4841 gnutls_supplemental_get_name: ADD.
4842 gnutls_authz_recv_callback_func,
4843 gnutls_authz_send_callback_func: ADD, callback prototypes.
4844 gnutls_authz_enable: ADD.
4845 gnutls_authz_send_x509_attr_cert,
4846 gnutls_authz_send_saml_assertion,
4847 gnutls_authz_send_x509_attr_cert_url,
4848 gnutls_authz_send_saml_assertion_url: ADD.
4849 GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element.
4850 gnutls_x509_crl_print: ADD.
4851 gnutls_x509_crl_get_signature: ADD.
4853 * Version 1.7.6 (released 2007-02-12)
4855 ** Support for 'otherName' Subject Alternative Names.
4856 The existing API gnutls_x509_crt_get_subject_alt_name may now return
4857 the new type GNUTLS_SAN_OTHERNAME together with the otherName value.
4858 To find out the otherName OID (necessary for proper parsing of the
4859 value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid.
4860 For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will
4861 return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to
4862 simplify OID matching. Suggested by Matthias Wimmer <m@tthias.eu>.
4864 ** Certtool can print otherName SAN values for certificates.
4865 For known otherName OIDs (currently only id-on-xmppAddr as defined by
4866 RFC 3920), it will also print the name.
4868 ** Fix TLS 1.2 RSA signing in servers.
4869 Before it used the old-style MD5+SHA1 signature, but the TLS
4870 signatures should be normal PKCS#1 signatures. FYI, we use and
4871 require that DigestInfo parameters are present and NULL for TLS 1.2.
4873 ** Add APIs to access X.509 extensions sequentially.
4874 The existing APIs gnutls_x509_crt_get_extension_oid() and
4875 gnutls_x509_crt_get_extension_by_oid() does not permit callers to
4876 inspect the extensions in the order defined by the certificate.
4878 ** Add API to extract signature value from X.509 certificates.
4879 The function is gnutls_x509_crt_get_signature.
4881 ** Fix crash when generating proxy certificates in batch mode.
4882 If you don't specify a proxy policy in batch mode, it will use
4885 ** Add API to print information about X.509 certificates.
4886 The function is gnutls_x509_crt_print.
4888 ** Certtool uses the new API gnutls_x509_crt_print to print certificate info.
4889 One consequence of this is that the output syntax has changed
4890 slightly. Some more fields are printed.
4894 ** API and ABI modifications:
4895 gnutls_x509_crt_print: ADD
4896 gnutls_certificate_print_formats_t: ADD, new enum.
4897 gnutls_x509_crt_get_signature: ADD.
4898 gnutls_x509_crt_get_extension_data: ADD.
4899 gnutls_x509_crt_get_extension_info: ADD.
4900 gnutls_x509_crt_get_subject_alt_othername_oid: ADD.
4901 GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element.
4902 GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element.
4904 * Version 1.7.5 (released 2007-02-06)
4906 ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential
4909 ** Default behaviour for the gnutls-cli and gnutls-serv tools improved.
4911 ** Fix --list output for gnutls-cli and gnutls-serv.
4912 Mention TLS1.2, SHA512 etc.
4914 ** Manual contains new section on setting up a test HTTP server.
4915 A server set up following those descriptions are available online via
4916 <http://www.gnutls.org/server.html>.
4918 ** Update of gnulib files.
4920 ** API and ABI modifications:
4921 No changes since last version.
4923 * Version 1.7.4 (released 2007-02-05)
4925 ** Support for RSA signing using SHA-256/384/512.
4926 A new self test "sha2" tries to build a long X.509 certificate chain
4927 testing all new hashes.
4929 ** The gnutls-serv tool now use static DH parameters if none are supplied.
4931 ** Discuss proxy certificates in the manual.
4933 ** Improve bibliographical citations in the manual.
4935 ** Update of gnulib files.
4937 ** Fix certtool template handling of pathLenConstraints.
4938 It now defaults to -1 instead of 0, which causes the field to be
4939 missing unless the template specify it.
4941 ** API and ABI modifications:
4944 GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values.
4947 GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values.
4948 GNUTLS_SIGN_RSA_SHA256,
4949 GNUTLS_SIGN_RSA_SHA384,
4950 GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values.
4952 * Version 1.7.3 (released 2007-02-01)
4954 ** New option to certtool: --generate-proxy.
4955 This will generate a Proxy Certificate from an end entity certificate.
4956 Proxy Certificates are documented in RFC 3820. You will need to
4957 specify the proxy certificate's private key with --load-privkey, the
4958 user certificate with --load-certificate and the private key used to
4959 sign the new proxy certificate with --load-ca-privkey. Certtool will
4960 query for proxy path length and the policy language OID. Currently
4961 only OIDs that have an empty policy are supported (which includes the
4962 two OIDs defined by RFC 3820).
4964 ** Certtool --certificate-info now prints information for Proxy Certificates.
4965 Before the proxy extension was just printed as DER encoded data.
4967 ** New APIs to set proxy subject names and get/set proxy cert extension.
4969 ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA.
4971 ** Added self-test to test for regressions of pathLenConstraint bug.
4972 Incidentally, this also test (some) other regressions or changes in
4973 the output from certtool --certificate-info.
4975 ** When certtool generates CA certificates, pressing enter on the path
4976 ** length constraint query will now remove the field.
4977 Before it set the path length constraint to 0, which is a rather poor
4980 ** Certtool now print times in UTC when printing certificate/CRL info.
4982 ** Add better fix to work around C++ compiler bug on Mac OS X.
4983 Reported and tiny patch provided by Matthias Scheler <tron@NetBSD.org>.
4985 ** Fix import of ASCII armored OpenPGP keys.
4986 Patch by ludovic.courtes@laas.fr (Ludovic Courtès).
4988 ** Update of gnulib files.
4990 ** API and ABI modifications:
4991 gnutls_x509_crt_set_proxy_dn: ADD.
4992 gnutls_x509_crt_set_proxy: ADD.
4993 gnutls_x509_crt_get_proxy: ADD.
4995 * Version 1.7.2 (released 2007-01-14)
4997 ** Certtool now print the value of the pathLenConstraints field for certs.
4999 ** Certtool now query for path length constraints when generating CA certs.
5000 For batch uses, the certtool configuration name is "path_len".
5001 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5003 ** Add new API to get/set pathLenConstraint in the Basic Constraints.
5004 The new functions gnutls_x509_crt_get_basic_constraints and
5005 gnutls_x509_crt_set_basic_constraints provide a superset of the
5006 functionality in the old gnutls_x509_crt_get_ca_status and
5007 gnutls_x509_crt_set_ca_status (respectively), but the old functions
5008 will continue to be supported.
5010 ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr.
5011 The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper
5012 OpenCDK release with this patch will be made soon, which should bump
5013 the OpenCDK version number. Patch by Mario Lenz <mario.lenz@gmx.net>.
5015 ** Certtool --to-p12 can now store more than one certificate in the blob.
5016 Before it could only store one certificate, but now it will read and
5017 store as many certificate there are from the --load-certificate file.
5018 Suggested by Sascha Ziemann <sascha.ziemann@secunet.com>.
5020 ** Clean up separation of gnutls and gnutls-extra for OpenPGP.
5021 In particular, the OpenPGP function variables are no longer part of
5022 the exported libgnutls interface, and no header files from
5023 libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables
5024 were never intended for non-internal purposes, and thus this does not
5025 imply a change in the external API/ABI.
5027 ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files.
5028 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5030 ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc.
5031 Before these parameters were set to make GnuTLS build under mingw32,
5032 however, they appear to no longer be necessary.
5034 ** A minor fix to the C++ library to make it build.
5035 Reported by Pavlov Konstantin <thresh@altlinux.ru>.
5037 ** Update of gnulib files.
5039 ** API and ABI modifications:
5040 gnutls_x509_crt_get_basic_constraints: ADD.
5041 gnutls_x509_crt_set_basic_constraints: ADD.
5042 cdk_pubkey_to_sexp: ADD (in opencdk).
5043 cdk_seckey_to_sexp: ADD (in opencdk).
5045 * Version 1.7.1 (released 2006-12-28)
5047 ** TLS 1.2 server side fix.
5048 The Certificate Request sent did not contain the list of supported
5049 hashes field, thus violating the protocol. It will now contain an
5050 empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5052 ** TLS 1.2 DSA signature verification fix.
5053 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5055 ** Fix the list of trusted CAs that server's send to clients.
5056 Before, the list contained issuer DN's instead of subject DN's of the
5057 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5059 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5060 Also added a self-test in tests/certificate_set_x509_crl.c to test the
5061 function. Reported by Max Kellermann <max@duempel.org>.
5063 ** Encode UID fields in DN's as DirectoryString.
5064 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5065 incorrect, it should have used DirectoryString. Now it will use
5066 DirectoryString for the UID field, but for backwards compatibility it
5067 will also accept IA5String UID's. Reported by Max Kellermann
5070 ** Improve out-of-sourcedir builds from CVS.
5071 Reported by ludovic.courtes@laas.fr (Ludovic Courtès).
5073 ** Bootstrap tools changed.
5074 We now require autoconf 2.61, automake 1.10, and gettext 0.16, when
5075 building GnuTLS from CVS. Libtool 1.5.22 is used.
5077 ** Fixed a syntax error in lib/gnutls.asn.
5078 Reported by Paul Millar <p.millar@physics.gla.ac.uk>.
5080 ** Added German translation of GnuTLS messages.
5082 ** Update of gnulib files.
5084 ** API and ABI modifications:
5085 No changes since last version.
5087 * Version 1.7.0 (released 2006-11-29)
5089 ** The default protocol priority try TLS 1.1 and TLS 1.2 too.
5090 The details is that the protocol priority set by
5091 `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL
5092 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0.
5094 ** Preliminary support for TLS 1.2.
5095 The client has been successfully tested against
5096 https://www.mikestoolbox.org:4433/.
5098 ** Anonself test now print a lot of debugging info, including TLS version.
5100 ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings.
5102 ** Update of gnulib files.
5104 ** API and ABI modifications:
5105 GNUTLS_TLS1_2: New gnutls_protocol_t enum member.
5107 *** Pulled up from stable 1.6.x branch:
5109 ** Fix ./configure failure with non-GCC compilers.
5110 This fixes the following error message:
5111 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5112 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5114 * Version 1.6.3 (released 2007-05-26)
5116 ** New API functions to extract DER encoded X.509 Subject/Issuer DN.
5117 Suggested by Nate Nielsen <nielsen-list@memberwebs.com>. Backported
5118 from the 1.7.x branch, see
5119 <http://lists.gnu.org/archive/html/help-gnutls/2007-05/msg00029.html>.
5121 ** Have PKCS8 parser return better error codes.
5122 Reported by Nate Nielsen <nielsen-list@memberwebs.com>, see
5123 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001653.html> and
5124 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-May/001654.html>.
5126 ** Fix mem leak for sessions with client authentication via certificates.
5127 Reported by Andrew W. Nosenko <andrew.w.nosenko@gmail.com>, see
5128 <http://lists.gnupg.org/pipermail/gnutls-dev/2007-April/001539.html>.
5130 ** Fix building of 'tlsia' self test.
5131 Earlier some gcc are known to build tlsia linking to
5132 $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in
5133 the build directory, even though command line parameters look OK.
5134 Changing order of some parameters fixes it.
5136 ** API and ABI modifications:
5137 gnutls_x509_crt_get_raw_issuer_dn: ADD.
5138 gnutls_x509_crt_get_raw_dn: ADD.
5140 * Version 1.6.2 (released 2007-04-18)
5142 ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields.
5143 Before, we remove the parameters field, which resulted in a slightly
5144 different DER encoding which in turn caused signature verification
5145 failures of GnuTLS-generated RSA certificates in some other
5146 implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs
5147 you read, this may or may not be correct, but our new behaviour appear
5148 to be consistent with other widely used implementations.
5150 ** Regenerate the PKIX ASN.1 syntax tree.
5151 For some reason, after changing the ASN.1 type of ldap-UID in the last
5152 release, the generated C file built from the ASN.1 schema was not
5153 refreshed. This can cause problems when reading/writing UID
5154 components inside X.500 Distinguished Names. Reported by devel
5155 <dev001@pas-world.com>.
5157 ** Updated translations.
5159 ** API and ABI modifications:
5160 No changes since last version.
5162 * Version 1.6.1 (released 2006-12-28)
5164 ** Fix the list of trusted CAs that server's send to clients.
5165 Before, the list contained issuer DN's instead of subject DN's of the
5166 trusted CAs. Reported by Max Kellermann <max@duempel.org>.
5168 ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it.
5169 Reported by Max Kellermann <max@duempel.org>.
5171 ** Encode UID fields in DN's as DirectoryString.
5172 Before GnuTLS encoded and parsed UID fields as IA5String. This was
5173 incorrect, it should have used DirectoryString. Now it will use
5174 DirectoryString for the UID field, but for backwards compatibility it
5175 will also accept IA5String UID's. Reported by Max Kellermann
5178 ** Fix ./configure failure with non-GCC compilers.
5179 This fixes the following error message:
5180 configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined.
5181 Reported by "Michael C. Vergallen" <mvergall@telenet.be>.
5183 ** API and ABI modifications:
5184 No changes since last version.
5186 * Version 1.6.0 (released 2006-11-17)
5188 ** No changes since 1.5.5.
5189 The major changes compared to the 1.4.x branch are:
5191 *** A GnuTLS C++ library is part of the official distribution.
5192 Currently there are no examples or documentation, but hopefully this
5193 will change. See gnutlsxx.h for the API.
5195 *** Windows is a supported platform.
5196 There are, however, two know bugs. One is related to select() in
5197 command line tools (not, nota bene, in the library), the other is a
5198 problem with libgcrypt that causes delays. Help is needed to resolve
5199 those issues, so we feel we can't delay the release because of this.
5201 *** New APIs for custom push/pull function error reporting.
5202 The new APIs are gnutls_transport_set_errno and
5203 gnutls_transport_set_global_errno. See the release notes for version
5204 1.5.4 for more information.
5206 *** Self tests are run under valgrind, if available. See --disable-valgrind.
5208 * Version 1.5.5 (released 2006-11-16)
5210 ** Correctly bump shared library version after adding new APIs.
5211 This was forgotten in the last release.
5213 ** Fix unsigned vs signed problem in ex-x509-info.c example.
5214 Reported by Tim Kosse <tim.kosse@filezilla-project.org>.
5216 ** Fix the rsa-md5-collision self test to work for MinGW+Wine.
5218 ** Update of gnulib files.
5220 ** API and ABI modifications:
5221 No changes since last version.
5223 * Version 1.5.4 (released 2006-11-07)
5225 ** New API functions to set errno in push/pull functions.
5226 Under Windows, setting the errno variable in a push/pull replacement
5227 may end up setting the wrong errno variable, and GnuTLS send/recv
5228 functions become confused about the real errno returned from a failed
5229 push/pull function. Therefor, we have added two APIs to set the errno
5230 variable used by GnuTLS. The APIs can also help to keep things
5231 thread-safe, by avoiding potentially global variables. Typically,
5232 instead of setting errno in your push/pull function, you will call one
5233 of these functions. It is recommended to use
5234 gnutls_transport_set_errno, but if you don't have the session variable
5235 easily accessible in the push/pull replacement function, you can use
5236 gnutls_transport_set_global_errno. Suggested by Tim Kosse
5237 <tim.kosse@filezilla-project.org>.
5239 void gnutls_transport_set_errno (gnutls_session_t session, int err);
5240 void gnutls_transport_set_global_errno (int err);
5242 ** When calling `recv' or `send' Windows errors are handled properly.
5243 The Windows recv/send functions doesn't use errno, and GnuTLS now use
5244 WSAGetLastError to access the error condition instead.
5246 ** Several OpenPGP API fixes.
5247 All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most
5248 important fix is to change the return value of
5249 gnutls_openpgp_privkey_get_pk_algorithm and
5250 gnutls_openpgp_key_get_pk_algorithm from 'int' to
5251 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI
5252 compatible with 'int').
5254 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5255 ** version, try to negotiate the highest version support by the GnuTLS server,
5256 ** instead of the lowest.
5257 Reported by <Pasi.Eronen@nokia.com>.
5259 ** Replace old constructs with use of gnulib modules.
5260 For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in
5261 the code. If the headers doesn't exist on the target system, gnulib
5262 will make sure its replacement header files are used instead.
5264 ** Fix SOVERSION computation for *.def files.
5265 This fixes build errors similar to "No rule to make target
5266 `libgnutls-`expr', needed by `all-am'." when building for Windows.
5268 ** gnutls_check-version uses strverscmp from gnulib.
5270 ** Update of gnulib files.
5272 ** API and ABI modifications:
5273 gnutls_transport_set_errno: ADD
5274 gnutls_transport_set_global_errno: ADD
5276 * Version 1.5.3 (released 2006-10-26)
5278 ** Add new self-test of RSA-MD5 signature chains.
5279 Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures
5280 when verifying X.509 chains. The code is in tests/rsa-md5-collision/
5281 and is based on the work by Marc Stevens et al, see
5282 <http://www.win.tue.nl/hashclash/TargetCollidingCertificates/>.
5284 ** Re-factor self tests.
5286 ** The include copy of Libtasn1 is updated to version 0.3.7.
5288 ** The included copy of OpenCDK is updated to version 0.5.11.
5290 ** Fix the filename of the *.def file on Windows after library version bump.
5292 ** Separated the gnulib directory into one for LGPL modules and one for GPL.
5293 This allows the GPL'd part of GnuTLS to take advantage of the GPL'd
5294 gnulib modules. Earlier we could only use the LGPL'ed module from
5295 gnulib, because two gnulib directories in the same project didn't
5298 ** API and ABI modifications:
5299 No changes since last version.
5301 * Version 1.5.2 (released 2006-10-03)
5303 ** Decrement the shared library version back to 13 (as in the 1.4.x branch).
5304 Note that if you installed 1.5.0 or 1.5.1, they will have a higher
5305 shared library version than this version, so you'll have to remove
5306 them and possibly relink your applications. The reason for this is
5307 that no API/ABI changes have been made since the 1.4.x branch, and
5308 that incrementing the shared library version was a mistake. Reported
5309 by Andreas Metzler <ametzler@downhill.at.eu.org>.
5311 ** Fix off-by-one error when computing length to malloc.
5312 The code is used by gnutls_openpgp_add_keyring_file and
5313 gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley"
5314 <agl@imperialviolet.org>.
5316 ** Add version script for the GnuTLS C++ library.
5317 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5319 ** Fix the C++ compiler detection logic.
5320 Reported by Andreas Metzler <ametzler@downhill.at.eu.org>.
5322 ** Update of gnulib files.
5324 ** API and ABI modifications:
5325 No changes since last version.
5327 * Version 1.5.1 (released 2006-09-21)
5329 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5330 ** Crypto 06 rump session attack.
5331 In particular, we check that the digestAlgorithm.parameters field is
5332 missing or empty, to avoid that it can contain "garbage" that may be
5333 used to alter the numeric properties of the signature. See
5334 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is
5335 not exactly the same as the problem we fix here). Reported by Yutaka
5336 OIWA <y.oiwa@aist.go.jp>.
5338 See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more
5339 up to date information.
5341 ** Add self test to test for above flaw.
5343 ** Fix gnutls-cli-debug regarding resume support detection.
5344 Earlier, if the session-id from the server had a length of 0, it would
5345 indicate that the server supports resumption, which isn't the case.
5346 Reported by Kataja Kai <kai.kataja@op.fi>.
5348 ** Fix building of examples on FreeBSD by including netinet/in.h.
5349 Reported by Roman Bogorodskiy <novel@FreeBSD.org>.
5351 ** Fix certtool bug that caused the private key to not be loaded when
5352 generating a certificate with --load-request, which in turn triggered
5353 another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported
5354 by Sascha Ziemann <sascha.ziemann@secunet.com>.
5356 ** gnutls-cli and gnutls-serv works on Windows.
5357 The problem was the select() call that doesn't work on file
5358 descriptors (stdin) on Windows. We borrowed some code from plibc to
5359 solve this. It appears to be somewhat unreliable though.
5361 ** Autoconf 2.60 is now used.
5363 ** API and ABI modifications:
5364 No changes since last version.
5366 * Version 1.5.0 (released 2006-08-13)
5368 ** Change SRP and Cert-Type extensions to match IANA registry.
5370 ** Fixed bug in OpenPGP authentication handshake.
5372 ** Improvements for building under MinGW.
5373 Provides internal inet_ntop and inet_pton functions and arpa/inet.h
5374 header. Calls WSAStartup and WSACleanup in gnutls_global_init and
5375 gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo
5376 at run-time from ws2_32.dll, and falls back on a simple replacement if
5377 it is not available. Builds the library with -mms-bitfields
5378 -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to
5379 create *.def files, which are installed.
5381 ** The examples now (conditionally) include config.h and link to gnulib.
5382 No other source changes were necessary, so the examples should
5383 continue to be possible to use stand-alone without any autoconf or
5386 ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx".
5387 You may unconditionally disable it with --disable-cxx. See
5388 includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the
5391 ** Made command line tool '--version' behave according to GNU Standards.
5392 This enables 'make distcheck' to succeed.
5394 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5396 ** Make --without-included-libtasn1 work.
5397 Reported by Daniel Black <dragonheart@gentoo.org>.
5399 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5400 See http://www.gnu.org/software/gnutls/security.html regardging
5401 GNUTLS-SA-2006-2 for more up to date information. Reported by
5402 satyakumar <satyam_kkd@hyd.hellosoft.com>.
5404 ** API and ABI modifications:
5405 No changes since last version.
5407 * Version 1.4.5 (released 2006-11-06)
5409 ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS
5410 ** version, try to negotiate the highest version support by the GnuTLS server,
5411 ** instead of the lowest.
5412 Reported by <Pasi.Eronen@nokia.com>.

5415 Reported by Adam Langley" <agl@imperialviolet.org>.
5417 ** API and ABI modifications:
5418 No changes since last version.
5420 * Version 1.4.4 (released 2006-09-12)
5422 ** Relax the test that caught signatures that exploit the variant of
5423 ** Bleichenbacher's Crypto 06 rump session attack on our
5424 ** verification logic flaw.
5425 In particular, we now permit the digestAlgorithm.parameters field to
5426 be present but empty, whereas in 1.4.3 we actually checked that the
5429 ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem.
5430 The messages are only printed in debug mode, which is not recommended
5431 for normal use, and thus logging this situation cannot be abused as an
5432 oracle in typical recommended situations.
5434 ** API and ABI modifications:
5435 No changes since last version.
5437 * Version 1.4.3 (released 2006-09-08)
5439 ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's
5440 ** Crypto 06 rump session attack.
5441 In particular, we check that the digestAlgorithm.parameters field is
5442 empty, to avoid that it can contain "garbage" that may be used to
5443 alter the numeric properties of the signature. See
5444 <http://www.imc.org/ietf-openpgp/mail-archive/msg14307.html> (which is

5451 ** Fix PKCS#1 decryption to avoid Bleichenbacher's Crypto 98 attack.
5452 See <http://www.bell-labs.com/user/bleichen/papers/pkcs.ps.gz>.

5458 ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key.
5460 ** API and ABI modifications:
5461 No changes since last version.
5463 * Version 1.4.2 (released 2006-08-12)
5465 ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic.
5466 This can happen if you call gnutls_certificate_verify_peers2 and have
5467 a certain mix of local CA certificates and the peer send special
5468 certificates, that together trigger certain behaviour. It is not
5469 known at this point whether the crash can be triggered without the
5470 special local CA certificate, and thus turn this into a remote crash
5471 of clients that verify server certificates when they talk to a server
5472 with the special server certificate. See GNUTLS-SA-2006-2 on
5473 http://www.gnu.org/software/gnutls/security.html for more up to date
5474 information. Reported by satyakumar <satyam_kkd@hyd.hellosoft.com>.
5476 ** Change SRP and Cert-Type extensions to match IANA registry.
5478 ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support.
5480 ** Make --without-included-libtasn1 work.
5481 Reported by Daniel Black <dragonheart@gentoo.org>.
5483 ** API and ABI modifications:
5484 No changes since last version.
5486 * Version 1.4.1 (released 2006-06-14)
5488 ** Replaced inactive ifdefs to enable openpgp support in test programs.
5490 ** Fixed bug in OpenPGP authentication handshake.
5492 ** Fixed typographical in man pages.
5494 ** Build fixes of the manual.
5496 ** Added Swedish translation.
5498 ** API and ABI modifications:
5499 No changes since last version.
5501 * Version 1.4.0 (released 2006-05-15)
5503 ** Remove GnuTLS 0.8.x compatibility functions.
5505 ** The libgcrypt RNG is initialized in gnutls_global_init().
5507 ** TLS/IA API changes from Emile van Bergen.
5508 A dummy credential structure is not needed now, if you wish to use the
5509 low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
5512 ** The self-tests are now run under valgrind, if it is installed.
5514 ** Libtasn1 is updated to 0.3.4, and that version is now required.
5516 ** The command line tools now use getaddrinfo and support IPv6.
5518 ** API and ABI modifications:
5519 _gnutls_x509_get_raw_crt_activation_time,
5520 _gnutls_x509_get_raw_crt_expiration_time: Removed.
5521 gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
5522 gnutls_ia_enable: Added.
5524 * Version 1.3.5 (released 2006-03-08)
5526 ** Error messages are now translated using GNU Gettext.
5528 ** The function gnutls_x509_crt_to_xml now return an internal error.
5529 This means that the code to convert X.509 certificates to XML format
5530 does not work any more. The reason is that the function called
5531 libtasn1 internal functions. It seems unclean for libtasn1 to export
5532 the APIs needed here. Instead it would be better to implement XML
5533 support inside libtasn1 properly. If you need this functionality
5534 strongly, please consider looking into implementing this suggested
5535 approach instead. As a workaround, you may also modify lib/x509/xml.c
5536 (change '#if 1' to '#if 0') and build using --with-included-libtasn1.
5538 ** Libraries are now built with libtool's -no-undefined.
5539 This helps producing libraries for Windows using mingw32.
5541 ** Doc fixes to explain that gnutls_record_send can block.
5543 ** Libtasn1 0.3.1 or later is now required.
5544 The include copy has been updated too.
5546 ** gnutls-cli can now recognize services and port numbers with the -p option.
5548 ** API and ABI modifications:
5549 No changes since last version.
5551 * Version 1.3.4 (released 2006-02-09)
5553 ** Fix read of out bounds bug in DER parser.
5554 Reported by Evgeny Legerov <admin@gleg.net>, and debugging help from
5555 Protover SSL. Libtasn1 0.2.18 is now required, which contains the
5556 previous bug fix. The included libtasn1 version in GnuTLS has been
5559 ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5560 longer invalidate a session if the underlying send fails, but it will
5561 prevent future writes. That is to allow reading the already received data.
5562 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5564 ** Corrected bugs in gnutls_certificate_set_x509_crl() and
5565 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5566 more than one certificates were added. Report and patch by Max Kellermann.
5568 ** Fix build problems of OpenCDK on AIX.
5569 Thanks to "Heiden, John" <JHeiden@UTNet.UToledo.Edu>.
5571 ** API and ABI modifications:
5572 No changes since last version.
5574 * Version 1.3.3 (released 2006-01-12)
5576 ** New API to access the TLS master secret.
5577 When possible, you should use the TLS PRF functions instead.
5578 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5580 ** Improved handling when multiple libraries use GnuTLS at the same time.
5581 Now gnutls_global_init() can be called multiple times, and
5582 gnutls_global_deinit() will only deallocate the structure when it has
5583 been called as many times as gnutls_global_init() was called.
5585 ** Added a self test of TLS resume functionality.
5587 ** Fix crash in TLS resume code, caused by TLS/IA changes.
5589 ** Documentation fixes about thread unsafety, prompted by
5590 ** discussion with bryanh@giraffe-data.com (Bryan Henderson).
5591 In particular, gnutls_global_init() and gnutls_global_deinit() are not
5592 thread safe. Careful callers may want to protect the call using a
5593 mutex. The problem could also be ignored, which would cause a memory
5594 leak under rare conditions when two threads invoke the function
5595 roughly at the same time.
5597 ** Add 'const' keywords in various places, from Frediano ZIGLIO.
5599 ** The code was indented again, including the external header files.
5601 ** API and ABI modifications:
5602 New functions to retrieve the master secret value:
5603 gnutls_session_get_master_secret
5605 Add a 'const' keyword to existing API:
5606 gnutls_x509_crq_get_challenge_password
5608 * Version 1.3.2 (released 2005-12-15)
5610 ** GnuTLS now support TLS Inner application (TLS/IA).
5611 This is per draft-funk-tls-inner-application-extension-01. This
5612 functionality is added to libgnutls-extra, so it is licensed under the
5613 GNU General Public License.
5615 ** New APIs to access the TLS Pseudo-Random-Function (PRF).
5616 The PRF is used by some protocols building on TLS, such as EAP-PEAP
5617 and EAP-TTLS. One function to access the raw PRF and one to access
5618 the PRF seeded with the client/server random fields are provided.
5619 Suggested by Jouni Malinen <jkmaline@cc.hut.fi>.
5621 ** New APIs to acceess the client and server random fields in a session.
5622 These fields can be useful by protocols using TLS. Note that these
5623 fields are typically used as input to the TLS PRF, and if this is your
5624 intended use, you should use the TLS PRF API that use the
5625 client/server random field directly. Suggested by Jouni Malinen
5626 <jkmaline@cc.hut.fi>.
5628 ** Internal type cleanups.
5629 The uint8, uint16, uint32 types have been replaced by uint8_t,
5630 uint16_t, uint32_t. Gnulib is used to guarantee the presence of
5631 correct types on platforms that lack them. The uint type have been
5632 replaced by unsigned.
5634 ** API and ABI modifications:
5635 New functions to invoke the TLS Pseudo-Random-Function (PRF):
5639 New functions to retrieve the session's client and server random values:
5640 gnutls_session_get_server_random
5641 gnutls_session_get_client_random
5643 New function, to perform TLS/IA handshake:
5646 New function to decide whether to do a TLS/IA handshake:
5647 gnutls_ia_handshake_p
5649 New functions to allocate a TLS/IA credential:
5650 gnutls_ia_allocate_client_credentials
5651 gnutls_ia_free_client_credentials
5652 gnutls_ia_allocate_server_credentials
5653 gnutls_ia_free_server_credentials
5655 New functions to handle the AVP callback:
5656 gnutls_ia_set_client_avp_function
5657 gnutls_ia_set_client_avp_ptr
5658 gnutls_ia_get_client_avp_ptr
5659 gnutls_ia_set_server_avp_function
5660 gnutls_ia_set_server_avp_ptr
5661 gnutls_ia_get_server_avp_ptr
5663 New functions, to toggle TLS/IA application phases:
5664 gnutls_ia_require_inner_phase
5666 New function to mix session keys with inner secret:
5667 gnutls_ia_permute_inner_secret
5669 Low-level API (used internally by gnutls_ia_handshake):
5670 gnutls_ia_endphase_send
5674 New functions that can be used after successful TLS/IA negotiation:
5675 gnutls_ia_generate_challenge
5676 gnutls_ia_extract_inner_secret
5678 Enum type with TLS/IA modes:
5681 Enum type with TLS/IA packet types:
5684 Enum values for TLS/IA alerts:
5685 GNUTLS_A_INNER_APPLICATION_FAILURE
5686 GNUTLS_A_INNER_APPLICATION_VERIFICATION
5688 New error codes, to signal when an application phase has finished:
5689 GNUTLS_E_WARNING_IA_IPHF_RECEIVED
5690 GNUTLS_E_WARNING_IA_FPHF_RECEIVED
5692 New error code to signal TLS/IA verify failure:
5693 GNUTLS_E_IA_VERIFY_FAILED
5695 * Version 1.3.1 (released 2005-12-08)
5697 ** Support for DHE-PSK cipher suites has been added.
5698 This method offers perfect forward secrecy.
5700 ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5701 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5703 ** Corrected a bug in certtool for 64 bit machines. Reported
5704 by Max Kellermann <max@duempel.org>.
5706 ** New function to set a X.509 private key and certificate pairs, and/or
5707 CRLs, from an PKCS#12 file, suggested by Emile van Bergen
5708 <emile@e-advies.nl>.
5710 The integrity of the PKCS#12 file is protected through a password
5711 based MAC; public-key based signatures for integrity protection are
5712 not supported. PKCS#12 bags may be encrypted using password derived
5713 symmetric keys, public-key based encryption is not supported. The
5714 PKCS#8 keys may be encrypted using passwords. The API use the same
5715 password for all operations. We believe that any more flexibility
5716 create too much complexity that would hurt overall security, but may
5717 add more PKCS#12 related APIs if real-world experience indicate
5720 ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys,
5721 reported by Emile van Bergen <emile@e-advies.nl>.
5722 This will enable "certtool -k -8" to parse those keys.
5724 ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords.
5725 Use "certtool -p -8" and press press enter at the prompt. Earlier,
5726 certtool would have encrypted the key using an empty password.
5728 ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys.
5729 Earlier it would have prompted the user for it, even if --password was
5732 ** Added self test of PKCS#8 parsing.
5733 Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and
5734 pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in
5737 ** API and ABI modifications:
5738 New function to set X.509 credentials from a PKCS#12 file:
5739 gnutls_certificate_set_x509_simple_pkcs12_file
5741 New gnutls_kx_algorithm_t enum type:
5744 New API to return session data (basically same as gnutls_session_get_data):
5745 gnutls_session_get_data2
5747 New API to set PSK Diffie-Hellman parameters:
5748 gnutls_psk_set_server_dh_params
5750 * Version 1.3.0 (2005-11-15)
5752 ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added.
5753 This add several new APIs, see below. Read the updated manual for
5754 more information. A new self test "pskself" has been added, that will
5755 test this functionality.
5757 ** The session resumption data are now system independent.
5759 ** The code has been re-indented to conform to the GNU coding style.
5761 ** Removed the RIPEMD ciphersuites.
5763 ** Added a discussion of the internals of gnutls in manual.
5765 ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin.
5767 ** Remove trailing comma in enums, for IBM C v6, from Albert Chin.
5769 ** Make sure config.h is included first in a few files, from Albert Chin.
5771 ** Don't use C++ comments ("//") as they are invalid, from Albert Chin.
5773 ** Don't install SRP programs and man pages if --disable-srp-authentication,
5776 ** API and ABI modifications:
5777 New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK
5779 New gnutls_credentials_type_t credential type:
5782 New credential types:
5783 gnutls_psk_server_credentials_t
5784 gnutls_psk_client_credentials_t
5786 New functions to allocate PSK credentials:
5787 gnutls_psk_allocate_client_credentials
5788 gnutls_psk_free_client_credentials
5789 gnutls_psk_free_server_credentials
5790 gnutls_psk_allocate_server_credentials
5792 New enum type for PSK key flags:
5793 gnutls_psk_key_flags
5795 New function prototypes for credential callback:
5796 gnutls_psk_client_credentials_function
5797 gnutls_psk_server_credentials_function
5799 New function to set PSK username and key:
5800 gnutls_psk_set_client_credentials
5802 New function to set PSK passwd file:
5803 gnutls_psk_set_server_credentials_file
5805 New function to extract PSK user in server:
5806 gnutls_psk_server_get_username
5808 New functions to set PSK callback:
5809 gnutls_psk_set_server_credentials_function
5810 gnutls_psk_set_client_credentials_function
5812 Use size_t instead of int for output size parameter:
5813 gnutls_srp_base64_encode
5814 gnutls_srp_base64_decode
5816 * Version 1.2.11 (2006-05-11)
5817 - The function gnutls_x509_crt_to_xml is not supported any more, and
5818 return an internal error. The reason is that the function called
5819 internal libtasn1 functions which are no longer exported from
5821 - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
5822 - Updated gnulib compatibility files.
5823 - Fixed _gnutls_x509_get_raw_crt_expiration_time and
5824 _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
5825 - API and ABI modifications:
5826 No changes since last version.
5828 * Version 1.2.10 (2006-02-09)
5829 - Fix read out bounds bug in DER parser. Reported by Evgeny Legerov
5830 <admin@gleg.net>, and debugging help from Protover SSL.
5831 - Libtasn1 0.2.18 is now required (contains the previous bug fix).
5832 The included version has been updated too.
5833 - Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
5834 Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
5835 - Corrected a bug in certtool for 64 bit machines. Reported
5836 by Max Kellermann <max@duempel.org>.
5837 - Corrected bugs in gnutls_certificate_set_x509_crl() and
5838 gnutls_certificate_set_x509_trust(), that caused memory corruption if
5839 more than one certificates were added. Report and patch by Max Kellermann.
5840 - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
5841 longer invalidate a session if the underlying send fails, but it will
5842 prevent future writes. That is to allow reading the already received data.
5843 Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>
5845 * Version 1.2.9 (2005-11-07)
5846 - Documentation was updated and improved.
5847 - RSA-MD2 is now supported for verifying digital signatures.
5848 - Due to cryptographic advances, verifying untrusted X.509
5849 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
5850 GNUTLS_CERT_INSECURE_ALGORITHM verification output. For
5851 applications that must remain interoperable, you can use the
5852 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
5853 flags when verifying certificates. Naturally, this is not
5854 recommended default behaviour for applications. To enable the
5855 broken algorithms, call gnutls_certificate_set_verify_flags with the
5856 proper flag, to change the verification mode used by
5857 gnutls_certificate_verify_peers2.
5858 - Make it possible to send empty data through gnutls_record_send,
5859 to align with the send(2) API.
5860 - Some changes in the certificate receiving part of handshake to prevent
5861 some possible errors with non-blocking servers.
5862 - Added numeric version symbols to permit simple CPP-based feature
5863 tests, suggested by Daniel Stenberg <daniel@haxx.se>.
5864 - The (experimental) low-level crypto alternative to libgcrypt used
5865 earlier (Nettle) has been replaced with crypto code from gnulib.
5866 This leads to easier re-use of these components in other projects,
5867 leading to more review and simpler maintenance. The new configure
5868 parameter --with-builtin-crypto replace the old --with-nettle, and
5869 must be used if you wish to enable this functionality. See README
5870 under "Experimental" for more information. Internally, GnuTLS has
5871 been updated to use the new "Generic Crypto" API in gl/gc.h. The
5872 API is similar to the old crypto/gc.h, because the gnulib code were
5873 based on GnuTLS's gc.h.
5874 - Fix compiler warning in the "anonself" self test.
5875 - API and ABI modifications:
5876 gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
5877 This doesn't reflect a change in behaviour,
5878 so we don't break backwards compatibility.
5879 GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
5880 GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
5881 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2,
5882 GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
5884 gnutls_x509_crt_list_verify,
5885 gnutls_x509_crt_verify, or
5886 gnutls_certificate_set_verify_flags.
5887 GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
5888 used when broken signature algorithms
5889 is used (currently RSA-MD2/MD5).
5890 LIBGNUTLS_VERSION_MAJOR,
5891 LIBGNUTLS_VERSION_MINOR,
5892 LIBGNUTLS_VERSION_PATCH,
5893 LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
5894 version number, can be used for feature existence
5897 * Version 1.2.8 (2005-10-07)
5898 - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers.
5899 - Don't install the auxilliary libexamples library used by the
5900 examples in doc/examples/ on "make install", report and tiny patch
5901 from Thomas Klausner <tk@giga.or.at>.
5902 - If you pass a X.509 CA or PGP trust database to the command line
5903 tool, it will now abort the connection if the server certificate
5904 validation fails. Use the parameter --insecure to continue even
5905 after certificate validation failures. Inspired from discussion
5906 with Alexander Kotelnikov <sacha@myxomop.com>.
5907 - The test for socklen_t has been moved to gnulib.
5908 - Link failures for duplicate or missing "program_name" symbol has been fixed,

5924 numbers, suggested by Fran <e_agf@yahoo.es>.
5925 - Certtool now uses the readline library (when available) when reading
5926 X.509 serial numbers.
5927 - Fixed build problems in getpass on uClibc and Mingw32 platforms.
5928 - Fixed compile warning regarding socklen_t on Mingw32, reported by
5929 Martin Lambers <marlam@marlam.de>.
5930 - Fixed examples in doc/examples/, suggested by Fran <e_agf@yahoo.es>.
5931 - Gnulib is now used for the core library, enabling future code cleanups.

5945 - Will now test for liblzo functionality in liblzo2 too, reported by
5946 Thomas Klausner <tk@giga.or.at>.
5947 - Minilibtasn1 is now 0.2.14 (no code changes).
5948 - Some code changes to avoid GTK-DOC warnings.
5949 - API and ABI modifications:
5950 No changes since last version.
5952 * Version 1.2.5 (2005-07-03)
5953 - More builddir != srcdir fixes, reported by Mike Castle
5954 <dalgoda@ix.netcom.com>.

5964 * Version 1.2.4 (2005-05-28)
5965 - Corrected some bugs that could affect 64 bit systems.
5966 - Some corrections in the header files to include the prototype
5967 of memmem properly (affected 64 bit systems). Report and patch
5968 by Yoann Vandoorselaere <yoann@prelude-ids.org>.
5969 - Introduced the --fix-key option to certtool, which can be used to
5970 regenerate the (optional) parameters in a private key. It should
5971 be used together with --key-info.
5972 - Corrected a bug in certificate chain verification that could lead
5973 to marking a trusted chain as non trusted, if the last certificate in
5974 the chain was a self signed one.
5975 - Gnulib portability files were updated.
5976 - License were updated to reflect new FSF address.
5977 - API and ABI modifications:
5978 No changes since last version.

5992 - Fixed pkcs12 friendly name and local key identifier decoding.
5993 - Internal cleanups, removed duplicate typedef/struct definitions,
5994 and made source code include external include file, to check
5995 function prototypes during compile time.
5996 - API and ABI modifications:
5997 No changes since last version. At least not intentional, but due
5998 to the include header changes, there may be inadvertant changes,
5999 please let us know if you find any.

6005 are not in the included list.
6006 - Added warning to certtool when MD5 is being used for digital
6008 - Optimizations ("-O2 -finline-functions") are not enabled by default,
6009 instead the standard autoconf defaults are used. Use `./configure
6010 CFLAGS="-O2 -finline-functions"' to get the old optimizations.
6011 - Added the option --get-dh-params to certtool, in order to get the
6012 parameters included in the library primes and generators.
6013 - Improved the semantics of GNUTLS_VERIFY_ALLOW_X509_V1_CA_CRT, to
6014 allow only trusted Version 1 CAs and introduced
6015 GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT which has the old semantics.
6016 - Nettle self tests now build properly, reported by Pierre
6017 <pierre42d@9online.fr>.
6018 - Eliminated some memory leaks in DHE and RSA-EXPORT cipher suites.
6019 Reported by Yoann Vandoorselaere <yoann@prelude-ids.org>.
6020 - If the library has been compiled with features disabled, a warning is
6021 issued during the compilation of any program.
6022 - API and ABI modifications:
6023 gnutls_x509_crt_list_import(): Add

6042 - Corrected the write of CRL distribution points.
6043 - The certificate chain verification function now checks certificates
6044 in the reverse order to minimize the spent resources.
6045 - Corrected several bugs found by Marcin Garski <mgarski@post.pl>
6046 - The functions gnutls_x509_crl_get_issuer_dn, gnutls_x509_crq_get_dn,
6047 gnutls_x509_crt_get_issuer_dn, gnutls_x509_crt_get_dn, and
6048 gnutls_x509_rdn_get now set *sizeof_buf to the buffer length that is
6049 required, instead of the string length. That is, the value has been
6050 incremented by 1 to account for the terminating zero. Reported by
6051 Martin Lambers <marlam@web.de>.
6052 - Debug output shouldn't crash on platforms that doesn't handle NULL
6053 printf %s values. Reported by Michael.Ringe@aachen.utimaco.de.
6054 - Sync included copy of libtasn1 with version 0.2.13.
6055 - Client X.509 authenticated connections via gnutls-cli should now work again.

6080 tiny patch by Aleix Conchillo Flaque <aleix@member.fsf.org>.
6081 - Add self test of PKCS#12 functionality in "certtool", based on test
6082 vectors from Joe Orton <joe@manyfish.co.uk>.
6083 - Fix library order in libgnutls*-config --libs output, to permit
6084 static linking, reported by Yoann Vandoorselaere
6085 <yoann@prelude-ids.org>.
