GNU TLS NEWS -- History of user-visible changes. -*- outline -*- Copyright (C) 2004, 2005, 2006, 2007 Simon Josefsson Copyright (C) 2000, 2001, 2002, 2003, 2004 Nikos Mavrogiannopoulos See the end for copying conditions. * Version 2.1.7 (unreleased) ** PKCS #8 parser can now encode/decode DSA keys. ** We now ignore received packets with unknown content types to follow the TLS spec. ** Updated gnutls_set_default_priority2() now renamed to gnutls_priority_set() and gnutls_priority_set_direct() which accept a string to indicate preferences of ciphersuite parameters. ** gnutls-cli and gnutls-serv now have a --priority option to set the priority string. ** The gnutls_*_convert_priority() functions were deprecated by the gnutls_priority_set() and gnutls_priority_set_direct(). ** Internal copy of OpenCDK upgraded to version 0.6.6. ** API and ABI modifications: gnutls_priority_init: ADDED gnutls_priority_deinit: ADDED gnutls_priority_set: ADDED gnutls_priority_set_direct: ADDED gnutls_set_default_priority2: RENAMED to gnutls_priority_set_direct() gnutls_mac_convert_priority: REMOVED gnutls_compression_convert_priority: REMOVED gnutls_protocol_convert_priority: REMOVED gnutls_kx_convert_priority: REMOVED gnutls_cipher_convert_priority: REMOVED gnutls_certificate_type_convert_priority: REMOVED gnutls_set_default_priority: UNDEPRECATED gnutls_set_default_priority_export: UNDEPRECATED * Version 2.1.6 (released 2007-11-15) ** Corrected bug in decompression of expanded compression data. ** Added the --to-p8 option to certtool to convert private keys to PKCS #8 keys. ** Introduced the GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR error code. ** gnutls_certificate_set_x509_key_* can now read PKCS #8 unencrypted private keys. ** Fixed GNUTLS_E_UNKNOWN_ALGORITHM vs GNUTLS_E_UNKNOWN_HASH_ALGORITHM. During the 2.1.x series the GNUTLS_E_UNKNOWN_HASH_ALGORITHM error code was renamed to GNUTLS_E_UNKNOWN_ALGORITHM, unfortunately without being documented. This caused some problems (e.g., debian #450854). To avoid backwards compatibility problems, this release revert this change, so that GNUTLS_E_UNKNOWN_HASH_ALGORITHM works just like it has done in GnuTLS 2.0.x and earlier, and add a new error code GNUTLS_E_UNKNOWN_ALGORITHM. ** Fixes several gtk-doc warnings. ** API and ABI modifications: GNUTLS_E_UNKNOWN_ALGORITHM: CHANGED. GNUTLS_E_UNKNOWN_HASH_ALGORITHM: CHANGED. GNUTLS_E_BASE64_UNEXPECTED_HEADER_ERROR: ADD. * Version 2.1.5 (released 2007-11-01) ** Fix PKCS#3 parameter export problem. ** Improve certtool queries, they now print the default value. ** Fix ABI version. ** Update gnulib files. ** API and ABI modifications: No changes since last version. * Version 2.1.4 (released 2007-10-27) ** Added the --v1 option to certtool, to allow generating X.509 version 1 certificates. ** certtool: Add option --disable-quick-random to enable the old behaviour of using /dev/random to generate keys. ** Added priority functions that accept strings. ** Added gnutls_set_default_priority2() which accepts a flag to indicate priorities preferences. ** Added gnutls_record_disable_padding() to allow servers talking to buggy clients that complain if the TLS 1.0 record protocol padding is used. ** Introduced gnutls_session_enable_compatibility_mode() to allow enabling all supported compatibility options (like disabling padding). ** The gnutls_certificate_set_openpgp_* functions were modified to include the format. This makes the interface consistent with the x509 functions. ** Internal copy of OpenCDK upgraded to version 0.6.5. ** Update gnulib files. ** API and ABI modifications: gnutls_certificate_set_openpgp_key_mem: MODIFIED gnutls_certificate_set_openpgp_key_file: MODIFIED gnutls_certificate_set_openpgp_keyring_mem: MODIFIED gnutls_certificate_set_openpgp_keyring_file: MODIFIED gnutls_set_default_priority: DEPRECATED gnutls_set_default_priority_export: DEPRECATED gnutls_set_default_priority2: ADDED gnutls_session_enable_compatibility_mode: ADDED gnutls_record_disable_padding: ADDED gnutls_mac_convert_priority: ADDED gnutls_compression_convert_priority: ADDED gnutls_protocol_convert_priority: ADDED gnutls_kx_convert_priority: ADDED gnutls_cipher_convert_priority: ADDED gnutls_certificate_type_convert_priority: ADDED gnutls_openpgp_key_t: RENAMED to gnutls_openpgp_crt_t gnutls_openpgp_key_status_t: RENAMED to gnutls_openpgp_crt_status_t gnutls_openpgp_send_key: RENAMED to gnutls_openpgp_send_cert gnutls_openpgp_key_init: RENAMED to gnutls_openpgp_crt_init gnutls_openpgp_key_import: RENAMED to gnutls_openpgp_crt_import gnutls_openpgp_key_export: RENAMED to gnutls_openpgp_crt_export gnutls_openpgp_key_check_hostname: RENAMED to gnutls_openpgp_crt_check_hostname gnutls_openpgp_key_get_creation_time: RENAMED to gnutls_openpgp_crt_get_creation_time gnutls_openpgp_key_get_expiration_time: RENAMED to gnutls_openpgp_crt_get_expiration_time gnutls_openpgp_key_get_fingerprint: RENAMED to gnutls_openpgp_crt_get_fingerprint gnutls_openpgp_key_get_version: RENAMED to gnutls_openpgp_crt_get_version gnutls_openpgp_key_get_pk_algorithm: RENAMED to gnutls_openpgp_crt_get_pk_algorithm gnutls_openpgp_key_get_name: RENAMED to gnutls_openpgp_crt_get_name gnutls_openpgp_key_deinit: RENAMED to gnutls_openpgp_crt_deinit gnutls_openpgp_key_get_id: RENAMED to gnutls_openpgp_crt_get_id gnutls_openpgp_key_get_key_usage: RENAMED to gnutls_openpgp_crt_get_key_usage gnutls_openpgp_key_verify_ring: RENAMED to gnutls_openpgp_crt_verify_ring gnutls_openpgp_key_verify_self: RENAMED to gnutls_openpgp_crt_verify_self * Version 2.1.3 (released 2007-10-17) ** TLS authorization support removed. This technique may be patented in the future, and it is not of crucial importance for the Internet community. After deliberation we have concluded that the best thing we can do in this situation is to encourage society not to adopt this technique. We have decided to lead the way with our own actions. ** Re-enabled the 256 bit ciphers in the default priorities. ** Corrected bugs in openpgp key verification using a keyring (both in gnutls and opencdk) ** API and ABI modifications: gnutls_certificate_set_openpgp_keyserver: REMOVED gnutls_authz_data_format_type_t, gnutls_authz_recv_callback_func, gnutls_authz_send_callback_func, gnutls_authz_enable, gnutls_authz_send_x509_attr_cert, gnutls_authz_send_saml_assertion, gnutls_authz_send_x509_attr_cert_url, gnutls_authz_send_saml_assertion_url: REMOVED. GNUTLS_SUPPLEMENTAL_USER_MAPPING_DATA: ADDED. To avoid that the gnutls_supplemental_data_format_type_t enum type becomes empty. * Version 2.1.2 (released 2007-10-14) ** Removed all the trustdb code from openpgp authentication. We now use only the well-specified keyrings. ** The 256 bit ciphers are not enabled in the default priorities. ** Added support for DSA2 using libgcrypt 1.3.0. ** certtool: Fixed data corruption when using --outder. ** Removed all the xml related stubs and functions. ** Added capability to set a callback after the client hello is received by the server in order to adjust parameters before the handshake. ** SRP was corrected to adhere to the latest draft (published soon as RFC) ** Corrected bug which did not allow a server to run without supporting certificates. ** Updated the DN parser which now prints wrongly decoded values as hex strings. ** certtool: Add option --quick-random. For generating low security test credentials. ** API and ABI modifications: gnutls_x509_crt_to_xml: REMOVED gnutls_openpgp_key_to_xml: REMOVED gnutls_openpgp_key_verify_trustdb: REMOVED gnutls_openpgp_trustdb_init: REMOVED gnutls_openpgp_trustdb_deinit: REMOVED gnutls_openpgp_trustdb_import: REMOVED gnutls_certificate_set_openpgp_trustdb: REMOVED gnutls_srp_client_credentials_function: CHANGED gnutls_handshake_set_post_client_hello_function: ADDED gnutls_mac_get_key_size: ADDED GNUTLS_E_OPENPGP_TRUSTDB_VERSION_UNSUPPORTED: DEPRECATED. GNUTLS_A_MISSING_SRP_USERNAME: DEPRECATED GNUTLS_A_UNKNOWN_SRP_USERNAME: DEPRECATED * Version 2.1.1 (released 2007-09-24) ** Added support for Camellia cipher, thanks to Yoshisato YANAGISAWA. Camellia is only enabled in GnuTLS if the installed libgcrypt has been compiled with Camellia support. See the libgcrypt documentation on how to enable it. Unconditionally disable it using the configure option --disable-camellia. Fixes #1. ** Properly document in the NEWS file the API change in the last release. ** API and ABI modifications: No changes since last version. * Version 2.1.0 (released 2007-09-20) ** Support for draft-rescorla-tls-opaque-prf-input-00.txt. The support is disabled by default. Since no value has been allocated by the IANA for this extension yet, you will need to provide one yourself by invoking './configure --enable-opaque-prf-input=42'. Fixes #2. ** Example code: Fix compilation flaw under MinGW. ** API and ABI modifications: gnutls_oprfi_callback_func: ADD, new typedef function prototype. gnutls_oprfi_enable_client: ADD, new function. gnutls_oprfi_enable_server: ADD, new function. * Version 2.0.2 (unreleased) ** Fix configure-time Guile detection. * Version 2.0.1 (released 2007-09-20) ** New directory doc/credentials/ with test credentials. This collects the test credentials from the web page and from src/. The script gnutls-http-serv has also been moved to that directory. ** Update SRP extension type and cipher suite with official IANA values. This breaks backwards compatibility with SRP in older versions of GnuTLS, but this is intentional to speed up the adoption of the official values. The old values we used were incorrect. ** Guile: Fix `x509-certificate-dn-oid' ** API and ABI modifications: No changes since last version. * Version 2.0.0 (released 2007-09-04) ** Included copy of Libtasn1 upgraded to version 1.1. ** Disable building of some examples if anonymous ciphers are disabled. ** Don't build examples for disabled features. ** API and ABI modifications: No changes since last version. * Version 1.7.19 (released 2007-08-27) ** Fix gnutls_error_is_fatal so that positive "errors" are non-critical. This solves connection problems in mutt, see . ** Update gnulib files. In particular, the getpass module -- with its dependencies on getline, getdelim, fseeko etc -- where moved from the lgl/ (used by the core library) directory to the gl/ directory (only used by the command line tools). The reason is that getpass is now only used by the command-line tools, and reducing the number of gnulib modules linked to the core library helps portability and reduces size. ** Fix warnings. ** Disable building of PGP examples if PGP is disabled. ** Included copy of OpenCDK upgraded to version 0.6.4. ** API and ABI modifications: No changes since last version. * Version 1.7.18 (released 2007-08-16) ** Install images for the info manual. This has a side effect of renaming the images. See for discussions on the approach chosen. ** Fix pointer mix to variables of different size. Patch extracted from . ** Fix warnings during build. Thanks to Andreas Metzler . ** API and ABI modifications: No changes since last version. * Version 1.7.17 (released 2007-08-15) ** New functions to perform external signing. Set the signing callback function (of the gnutls_sign_func prototype) using the gnutls_sign_callback_set function. In the callback, you may find the new functions gnutls_x509_privkey_sign_hash and gnutls_openpgp_privkey_sign_hash useful. A new function gnutls_sign_callback_get is also added, to retrieve the function pointer. Thanks to "Alon Bar-Lev" for comments and testing. ** New self test of client and server authenticated X.509 TLS sessions. See tests/x509self.c and tests/x509signself.c. The latter also tests the new external signing callback interface. ** New errors GNUTLS_E_APPLICATION_ERROR_MIN..GNUTLS_E_APPLICATION_ERROR_MAX. These two actually describe the outer limits of a range of error codes reserved to the application. All of the errors are treated as fatal by the library (it has to since it doesn't know the semantics of the error codes). This can be useful in callbacks, to signal some application-specific error condition, which will usually eventually cause some gnutls API to return the same error code as the callback, which then can be inspected by the application. Note that error codes are negative. ** gnutls_set_default_priority now disable TLS 1.2 by default. The RFC is not released yet, and we're approaching a major release so let's not enable it just yet. ** Fix namespace so that gnutls_*_t is used consistently. Before, many places in the GnuTLS code used the old deprecated type names without the '_t' suffix. ** Build fixes for Guile code. Patch from Ludovic Courtes . ** More documentation fixes. In particular, the section headings were modified for casing. By Ludovic Courtes . ** Updated Polish and Swedish translations. Thanks to Jakub Bogusz and Daniel Nylander . ** API and ABI modifications: gnutls_sign_func: ADD, new type for sign callback. gnutls_sign_callback_set: ADD, new function to set sign callback. gnutls_sign_callback_get: ADD, new function to retrieve sign callback. gnutls_x509_privkey_sign_hash, gnutls_openpgp_privkey_sign_hash: ADD, new functions useful in sign callback. GNUTLS_E_APPLICATION_ERROR_MIN, GNUTLS_E_APPLICATION_ERROR_MAX: ADD, new CPP #defines for error codes. * Version 1.7.16 (released 2007-08-07) ** Fix sanity checks and return values in certificate selection. In some cases, GnuTLS omitted to report suitable error codes when no suitable certificate was found. ** Fix gnutls-cli starttls EOF on Mac OS X. Thanks to Hal Eden . ** Documentation fixes. In particular, the section headings were modified for casing. By Ludovic Courtes . ** Update gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.15 (released 2007-07-02) ** Fix self-tests key-id under mingw32. ** Test that the Guile header files are recent enough to work. Before we just tested that the command line tool 'guile' was recent enough, which may not be sufficient if you still have an old libguile.h header installed. ** Guile bindings are now installed under $prefix by default. Use --without-guile-site-dir to install it under $pkgdatadir/site/ where $pkgdatadir is as returned by "guile-config info pkgdatadir". Use --with-guile-site-dir=/your/own/path to specify the path manually. The default, --with-guile-site-dir, will install the Guile bindings under $datadir/guile/site. There is a new section 'Guile Preparations' in the manual that discuss these issues. ** Fix run-time library path ordering in linking the Guile bindings. ** Improved manual on downloading, installing, getting help, bug reports etc. Suggested by Ludovic Courtès . ** Add Malay message translations. Thanks to Sharuzzaman Ahmat Raslan . ** API and ABI modifications: No changes since last version. * Version 1.7.14 (released 2007-06-26) ** Don't enable Guile bindings unless we have Guile 1.8 or later. Patch from Ludovic Courtès . ** Fix memory leak during DSA signature verification. Patch from Ludovic Courtès . ** Fix crash in gnutls-cli when TLS handshake fails. Reported by Marc Haber and Andreas Metzler via Debian BTS #429183, see . ** Minor OpenPGP fixes in stream_to_datum. Patch from Timo Schulz and Ludovic Courtès . ** Fix off-by-one in TLS 1.2 handshake. Patch from Ludovic Courtès . ** Minor Guile binding self-test cleanup. Patch from Ludovic Courtès . ** Update gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.13 (released 2007-06-11) ** OpenCDK copy updated to version 0.6.3. ** Build fixes for GnuTLS Guile bindings. Patch from Ludovic Courtès . ** Build fix for GTK-DOC manual. ** Update gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.12 (released 2007-06-08) ** Guile bindings for GnuTLS have been included. Contributed by Ludovic Courtès . There is a new chapter 'Guile Bindings' in the manual. ** Have PKCS8 parser return better error codes. Reported by Nate Nielsen , see and . ** Fix mem leak for sessions with client authentication via certificates. Reported by Andrew W. Nosenko , see . ** Fix mem leaks. Reported by Dennis Vshivkov , see . Added self-test tests/parse_ca.c to test regressions. ** Fix build failures related to missing images in manual. Reported by Andreas Metzler . ** Update gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.11 (released 2007-05-26) ** Include opencdk.h in the release. Reported by Roman Bogorodskiy . ** API and ABI modifications: No changes since last version. * Version 1.7.10 (released 2007-05-25) ** New API functions to extract DER encoded X.509 Subject/Issuer DN. Suggested by Nate Nielsen . ** Update of gnulib files. ** GnuTLS is now developed in GIT instead of CVS. See for a public repository. ** API and ABI modifications: gnutls_x509_crt_get_raw_issuer_dn: ADD. gnutls_x509_crt_get_raw_dn: ADD. * Version 1.7.9 (released 2007-05-12) ** X.509 certificates are preferred over OpenPGP keys. This is a change in the semantics of gnutls_set_default_priority. ** The included copy of OpenCDK has been updated to 0.6.1. There has been some API changes in OpenCDK, and the GnuTLS layer have been modified as well. Note that while there are API/ABI incompatible changes in OpenCDK, this does not influence GnuTLS's API/ABI because its API/ABI have not changed. From this version on, GnuTLS requires OpenCDK 0.6.0 or later. ** Fix build failure caused by missing doc/gnutls-logo.pdf. ** Change certtool's default serial number from 0 to a time-based value. ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields. Before, we remove the parameters field, which resulted in a slightly different DER encoding which in turn caused signature verification failures of GnuTLS-generated RSA certificates in some other implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs you read, this may or may not be correct, but our new behaviour appear to be consistent with other widely used implementations. ** Fix mem leaks in gnutls_x509_crt_print. ** API and ABI modifications: No changes since last version. * Version 1.7.8 (released 2007-04-16) ** Added examples for the authorization extension. See doc/examples/ex-client-authz.c and doc/examples/ex-serv-authz.c. ** The examples only use gnutls_set_default_priority(). The exception is when DH_ANON is needed. ** Improve gnutls_set_default_priority() priorities. The new approach is for it to try and negotiate all secure and standard mechanisms available. Currently, DH_ANON ciphersuites and LZO compressions are not enabled by default, because they are, respectively, insecure and non-standardized. Note that TLS 1.2 will not be enabled by default in non-experimental release until it has been approved by the IETF. ** gnutls-cli and gnutls-serv now uses the library's default priorities. This means that to get DH_ANON and LZO compression, you'll need to specify that manually using '--kx anon' or '--comp lzo'. ** Minor fixes to the human display format of X.509 certificates. ** New APIs to extract Distinguished Name's from X.509 certificates. Based on patch from Howard Chu . ** Improved library searching for opencdk. It will now add the appropriate -R or -Wl,-rpath flags as necessary. The deprecated opencdk.m4 is no longer used. ** New APIs to list supported algorithms in the library. The APIs are gnutls_cipher_list, gnutls_mac_list, gnutls_compression_list, gnutls_protocol_list, gnutls_certificate_type_list, gnutls_kx_list, and gnutls_cipher_suite_info. Suggested by Howard Chu . ** The gnutls_x509_crt_get_key_id API now handle non-RSA/DSA keys. ** New configure option --disable-tls-authorization to disable tls-authz. ** Fix prototype for `gnutls_psk_set_client_credentials'. The last parameter was renamed from 'flags' to 'format' and the type changed from 'unsigned int' to 'gnutls_psk_key_flags' (an enum type), which shouldn't cause any ABI changes. Reported by ludo@chbouib.org (Ludovic Courtès). ** Fix allocation in gnutls_certificate_set_openpgp_key. Tiny patch from ludo@chbouib.org (Ludovic Courtès). ** API and ABI modifications: gnutls_x509_dn_t: ADD. gnutls_x509_ava_st: ADD. gnutls_x509_crt_get_subject, gnutls_x509_crt_get_issuer: ADD. gnutls_x509_dn_get_rdn_ava: ADD. gnutls_cipher_list: ADD. gnutls_mac_list: ADD. gnutls_compression_list: ADD. gnutls_protocol_list: ADD. gnutls_certificate_type_list: ADD. gnutls_kx_list: ADD. gnutls_cipher_suite_info: ADD. * Version 1.7.7 (released 2007-02-22) ** Support for supplemental handshake messages and authorization data. Supplemental data is described in RFC 4680 and the authorization extensions in draft-housley-tls-authz-extns-07. ** Support for authorization data in gnutls-cli and gnutls-serv. New parameters --authz-x509-attr-cert and --authz-saml-assertion. ** Fix for gnutls_x509_crt_check_hostname. Before it would have reported that the certificate matched a hostname when it did not have any dNSName or any CN field. Report and tiny patch from "Richard W.M. Jones" . ** New self test for RFC 2818 comparison in gnutls_x509_crt_check_hostname. Tests regressions of the bug, and several other features. ** GnuTLS now matches URI's with IP Addresses against iPAddress SAN's. Before there were no support for iPAddress SAN's during comparison. ** New API to print information about CRL's. The function is gnutls_x509_crl_print. ** New API to extract signature value from CRL's. The function is gnutls_x509_crl_get_signature. ** Support for directoryName Subject Alternative Name's. The gnutls_x509_crt_get_subject_alt_name function returns the DN as a string in the provided buffer. ** Internal improvements to certtool. It uses gnutls_x509_crl_print to print CRL information. It uses some more gnulib modules to simplify error handling. ** API and ABI modifications: GNUTLS_HANDSHAKE_SUPPLEMENTAL: ADD, new gnutls_handshake_description_t element. gnutls_supplemental_data_format_type_t: ADD. gnutls_authz_data_format_type_t: ADD. gnutls_supplemental_get_name: ADD. gnutls_authz_recv_callback_func, gnutls_authz_send_callback_func: ADD, callback prototypes. gnutls_authz_enable: ADD. gnutls_authz_send_x509_attr_cert, gnutls_authz_send_saml_assertion, gnutls_authz_send_x509_attr_cert_url, gnutls_authz_send_saml_assertion_url: ADD. GNUTLS_SAN_DN: ADD, new gnutls_x509_subject_alt_name_t element. gnutls_x509_crl_print: ADD. gnutls_x509_crl_get_signature: ADD. * Version 1.7.6 (released 2007-02-12) ** Support for 'otherName' Subject Alternative Names. The existing API gnutls_x509_crt_get_subject_alt_name may now return the new type GNUTLS_SAN_OTHERNAME together with the otherName value. To find out the otherName OID (necessary for proper parsing of the value), use the new API gnutls_x509_crt_get_subject_alt_othername_oid. For known OIDs, gnutls_x509_crt_get_subject_alt_othername_oid will return "virtual" SAN values, e.g., GNUTLS_SAN_OTHERNAME_XMPP to simplify OID matching. Suggested by Matthias Wimmer . ** Certtool can print otherName SAN values for certificates. For known otherName OIDs (currently only id-on-xmppAddr as defined by RFC 3920), it will also print the name. ** Fix TLS 1.2 RSA signing in servers. Before it used the old-style MD5+SHA1 signature, but the TLS signatures should be normal PKCS#1 signatures. FYI, we use and require that DigestInfo parameters are present and NULL for TLS 1.2. ** Add APIs to access X.509 extensions sequentially. The existing APIs gnutls_x509_crt_get_extension_oid() and gnutls_x509_crt_get_extension_by_oid() does not permit callers to inspect the extensions in the order defined by the certificate. ** Add API to extract signature value from X.509 certificates. The function is gnutls_x509_crt_get_signature. ** Fix crash when generating proxy certificates in batch mode. If you don't specify a proxy policy in batch mode, it will use id-ppl-inheritALL. ** Add API to print information about X.509 certificates. The function is gnutls_x509_crt_print. ** Certtool uses the new API gnutls_x509_crt_print to print certificate info. One consequence of this is that the output syntax has changed slightly. Some more fields are printed. ** Doc fixes. ** API and ABI modifications: gnutls_x509_crt_print: ADD gnutls_certificate_print_formats_t: ADD, new enum. gnutls_x509_crt_get_signature: ADD. gnutls_x509_crt_get_extension_data: ADD. gnutls_x509_crt_get_extension_info: ADD. gnutls_x509_crt_get_subject_alt_othername_oid: ADD. GNUTLS_SAN_OTHERNAME: ADD, new gnutls_x509_subject_alt_name_t element. GNUTLS_SAN_OTHERNAME_XMPP: ADD, new gnutls_x509_subject_alt_name_t element. * Version 1.7.5 (released 2007-02-06) ** Servers won't negotiate SRP RSA/DSS cipher suites if no SRP credential ** is set. ** Default behaviour for the gnutls-cli and gnutls-serv tools improved. ** Fix --list output for gnutls-cli and gnutls-serv. Mention TLS1.2, SHA512 etc. ** Manual contains new section on setting up a test HTTP server. A server set up following those descriptions are available online via . ** Update of gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.4 (released 2007-02-05) ** Support for RSA signing using SHA-256/384/512. A new self test "sha2" tries to build a long X.509 certificate chain testing all new hashes. ** The gnutls-serv tool now use static DH parameters if none are supplied. ** Discuss proxy certificates in the manual. ** Improve bibliographical citations in the manual. ** Update of gnulib files. ** Fix certtool template handling of pathLenConstraints. It now defaults to -1 instead of 0, which causes the field to be missing unless the template specify it. ** API and ABI modifications: GNUTLS_MAC_SHA256, GNUTLS_MAC_SHA384, GNUTLS_MAC_SHA512: New gnutls_mac_algorithm_t values. GNUTLS_DIG_SHA256, GNUTLS_DIG_SHA384, GNUTLS_DIG_SHA512: New gnutls_digest_algorithm_t values. GNUTLS_SIGN_RSA_SHA256, GNUTLS_SIGN_RSA_SHA384, GNUTLS_SIGN_RSA_SHA512: New gnutls_sign_algorithm_t values. * Version 1.7.3 (released 2007-02-01) ** New option to certtool: --generate-proxy. This will generate a Proxy Certificate from an end entity certificate. Proxy Certificates are documented in RFC 3820. You will need to specify the proxy certificate's private key with --load-privkey, the user certificate with --load-certificate and the private key used to sign the new proxy certificate with --load-ca-privkey. Certtool will query for proxy path length and the policy language OID. Currently only OIDs that have an empty policy are supported (which includes the two OIDs defined by RFC 3820). ** Certtool --certificate-info now prints information for Proxy Certificates. Before the proxy extension was just printed as DER encoded data. ** New APIs to set proxy subject names and get/set proxy cert extension. ** Fix parsing of pathLenConstraints in BasicConstraints with missing cA. ** Added self-test to test for regressions of pathLenConstraint bug. Incidentally, this also test (some) other regressions or changes in the output from certtool --certificate-info. ** When certtool generates CA certificates, pressing enter on the path ** length constraint query will now remove the field. Before it set the path length constraint to 0, which is a rather poor default. ** Certtool now print times in UTC when printing certificate/CRL info. ** Add better fix to work around C++ compiler bug on Mac OS X. Reported and tiny patch provided by Matthias Scheler . ** Fix import of ASCII armored OpenPGP keys. Patch by ludovic.courtes@laas.fr (Ludovic Courtès). ** Update of gnulib files. ** API and ABI modifications: gnutls_x509_crt_set_proxy_dn: ADD. gnutls_x509_crt_set_proxy: ADD. gnutls_x509_crt_get_proxy: ADD. * Version 1.7.2 (released 2007-01-14) ** Certtool now print the value of the pathLenConstraints field for certs. ** Certtool now query for path length constraints when generating CA certs. For batch uses, the certtool configuration name is "path_len". Suggested by Sascha Ziemann . ** Add new API to get/set pathLenConstraint in the Basic Constraints. The new functions gnutls_x509_crt_get_basic_constraints and gnutls_x509_crt_set_basic_constraints provide a superset of the functionality in the old gnutls_x509_crt_get_ca_status and gnutls_x509_crt_set_ca_status (respectively), but the old functions will continue to be supported. ** Add new API in OpenCDK to extract public/secret OpenPGP key to S-expr. The functions are cdk_pubkey_to_sexp and cdk_seckey_to_sexp. A proper OpenCDK release with this patch will be made soon, which should bump the OpenCDK version number. Patch by Mario Lenz . ** Certtool --to-p12 can now store more than one certificate in the blob. Before it could only store one certificate, but now it will read and store as many certificate there are from the --load-certificate file. Suggested by Sascha Ziemann . ** Clean up separation of gnutls and gnutls-extra for OpenPGP. In particular, the OpenPGP function variables are no longer part of the exported libgnutls interface, and no header files from libgnutls-extra (GPL) are needed by libgnutls (LGPL). The variables were never intended for non-internal purposes, and thus this does not imply a change in the external API/ABI. ** Print URL to gaa when missing, and fix srcdir!=builddir for GAA files. Reported by ludovic.courtes@laas.fr (Ludovic Courtès). ** GnuTLS no longer uses -mms-bitfields --enable-runtime-pseudo-reloc. Before these parameters were set to make GnuTLS build under mingw32, however, they appear to no longer be necessary. ** A minor fix to the C++ library to make it build. Reported by Pavlov Konstantin . ** Update of gnulib files. ** API and ABI modifications: gnutls_x509_crt_get_basic_constraints: ADD. gnutls_x509_crt_set_basic_constraints: ADD. cdk_pubkey_to_sexp: ADD (in opencdk). cdk_seckey_to_sexp: ADD (in opencdk). * Version 1.7.1 (released 2006-12-28) ** TLS 1.2 server side fix. The Certificate Request sent did not contain the list of supported hashes field, thus violating the protocol. It will now contain an empty list. Reported by ludovic.courtes@laas.fr (Ludovic Courtès). ** TLS 1.2 DSA signature verification fix. Reported by ludovic.courtes@laas.fr (Ludovic Courtès). ** Fix the list of trusted CAs that server's send to clients. Before, the list contained issuer DN's instead of subject DN's of the trusted CAs. Reported by Max Kellermann . ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it. Also added a self-test in tests/certificate_set_x509_crl.c to test the function. Reported by Max Kellermann . ** Encode UID fields in DN's as DirectoryString. Before GnuTLS encoded and parsed UID fields as IA5String. This was incorrect, it should have used DirectoryString. Now it will use DirectoryString for the UID field, but for backwards compatibility it will also accept IA5String UID's. Reported by Max Kellermann . ** Improve out-of-sourcedir builds from CVS. Reported by ludovic.courtes@laas.fr (Ludovic Courtès). ** Bootstrap tools changed. We now require autoconf 2.61, automake 1.10, and gettext 0.16, when building GnuTLS from CVS. Libtool 1.5.22 is used. ** Fixed a syntax error in lib/gnutls.asn. Reported by Paul Millar . ** Added German translation of GnuTLS messages. ** Update of gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.7.0 (released 2006-11-29) ** The default protocol priority try TLS 1.1 and TLS 1.2 too. The details is that the protocol priority set by `gnutls_set_default_priority' has been changed from TLS 1.0 and SSL 3.0 to TLS 1.2, TLS 1.1, TLS 1.0 and SSL 3.0. ** Preliminary support for TLS 1.2. The client has been successfully tested against https://www.mikestoolbox.org:4433/. ** Anonself test now print a lot of debugging info, including TLS version. ** Doc fixes in OpenCDK, to avoid some gtk-doc warnings. ** Update of gnulib files. ** API and ABI modifications: GNUTLS_TLS1_2: New gnutls_protocol_t enum member. *** Pulled up from stable 1.6.x branch: ** Fix ./configure failure with non-GCC compilers. This fixes the following error message: configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined. Reported by "Michael C. Vergallen" . * Version 1.6.3 (released 2007-05-26) ** New API functions to extract DER encoded X.509 Subject/Issuer DN. Suggested by Nate Nielsen . Backported from the 1.7.x branch, see . ** Have PKCS8 parser return better error codes. Reported by Nate Nielsen , see and . ** Fix mem leak for sessions with client authentication via certificates. Reported by Andrew W. Nosenko , see . ** Fix building of 'tlsia' self test. Earlier some gcc are known to build tlsia linking to $prefix/lib/libgnutls-extra.so rather than the libgnutls-extra.so in the build directory, even though command line parameters look OK. Changing order of some parameters fixes it. ** API and ABI modifications: gnutls_x509_crt_get_raw_issuer_dn: ADD. gnutls_x509_crt_get_raw_dn: ADD. * Version 1.6.2 (released 2007-04-18) ** Fix X.509 signing with RSA-PKCS#1 to set a NULL parameters fields. Before, we remove the parameters field, which resulted in a slightly different DER encoding which in turn caused signature verification failures of GnuTLS-generated RSA certificates in some other implementations (e.g., GnuPG 2.x's gpgsm). Depending on which RFCs you read, this may or may not be correct, but our new behaviour appear to be consistent with other widely used implementations. ** Regenerate the PKIX ASN.1 syntax tree. For some reason, after changing the ASN.1 type of ldap-UID in the last release, the generated C file built from the ASN.1 schema was not refreshed. This can cause problems when reading/writing UID components inside X.500 Distinguished Names. Reported by devel . ** Updated translations. ** API and ABI modifications: No changes since last version. * Version 1.6.1 (released 2006-12-28) ** Fix the list of trusted CAs that server's send to clients. Before, the list contained issuer DN's instead of subject DN's of the trusted CAs. Reported by Max Kellermann . ** Fix gnutls_certificate_set_x509_crl to initialize the CRL before using it. Reported by Max Kellermann . ** Encode UID fields in DN's as DirectoryString. Before GnuTLS encoded and parsed UID fields as IA5String. This was incorrect, it should have used DirectoryString. Now it will use DirectoryString for the UID field, but for backwards compatibility it will also accept IA5String UID's. Reported by Max Kellermann . ** Fix ./configure failure with non-GCC compilers. This fixes the following error message: configure: error: conditional "HAVE_LD_OUTPUT_DEF" was never defined. Reported by "Michael C. Vergallen" . ** API and ABI modifications: No changes since last version. * Version 1.6.0 (released 2006-11-17) ** No changes since 1.5.5. The major changes compared to the 1.4.x branch are: *** A GnuTLS C++ library is part of the official distribution. Currently there are no examples or documentation, but hopefully this will change. See gnutlsxx.h for the API. *** Windows is a supported platform. There are, however, two know bugs. One is related to select() in command line tools (not, nota bene, in the library), the other is a problem with libgcrypt that causes delays. Help is needed to resolve those issues, so we feel we can't delay the release because of this. *** New APIs for custom push/pull function error reporting. The new APIs are gnutls_transport_set_errno and gnutls_transport_set_global_errno. See the release notes for version 1.5.4 for more information. *** Self tests are run under valgrind, if available. See --disable-valgrind. * Version 1.5.5 (released 2006-11-16) ** Correctly bump shared library version after adding new APIs. This was forgotten in the last release. ** Fix unsigned vs signed problem in ex-x509-info.c example. Reported by Tim Kosse . ** Fix the rsa-md5-collision self test to work for MinGW+Wine. ** Update of gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.5.4 (released 2006-11-07) ** New API functions to set errno in push/pull functions. Under Windows, setting the errno variable in a push/pull replacement may end up setting the wrong errno variable, and GnuTLS send/recv functions become confused about the real errno returned from a failed push/pull function. Therefor, we have added two APIs to set the errno variable used by GnuTLS. The APIs can also help to keep things thread-safe, by avoiding potentially global variables. Typically, instead of setting errno in your push/pull function, you will call one of these functions. It is recommended to use gnutls_transport_set_errno, but if you don't have the session variable easily accessible in the push/pull replacement function, you can use gnutls_transport_set_global_errno. Suggested by Tim Kosse . void gnutls_transport_set_errno (gnutls_session_t session, int err); void gnutls_transport_set_global_errno (int err); ** When calling `recv' or `send' Windows errors are handled properly. The Windows recv/send functions doesn't use errno, and GnuTLS now use WSAGetLastError to access the error condition instead. ** Several OpenPGP API fixes. All suggested by ludovic.courtes@laas.fr (Ludovic Courtès). The most important fix is to change the return value of gnutls_openpgp_privkey_get_pk_algorithm and gnutls_openpgp_key_get_pk_algorithm from 'int' to 'gnutls_pk_algorithm_t', which is an enum type (and thus API/ABI compatible with 'int'). ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS ** version, try to negotiate the highest version support by the GnuTLS server, ** instead of the lowest. Reported by . ** Replace old constructs with use of gnulib modules. For example, we can now assume unistd.h, sys/stat.h, sys/socket.h in the code. If the headers doesn't exist on the target system, gnulib will make sure its replacement header files are used instead. ** Fix SOVERSION computation for *.def files. This fixes build errors similar to "No rule to make target `libgnutls-`expr', needed by `all-am'." when building for Windows. ** gnutls_check-version uses strverscmp from gnulib. ** Update of gnulib files. ** API and ABI modifications: gnutls_transport_set_errno: ADD gnutls_transport_set_global_errno: ADD * Version 1.5.3 (released 2006-10-26) ** Add new self-test of RSA-MD5 signature chains. Note that we already, since GnuTLS 1.2.9, reject RSA-MD5 signatures when verifying X.509 chains. The code is in tests/rsa-md5-collision/ and is based on the work by Marc Stevens et al, see . ** Re-factor self tests. ** The include copy of Libtasn1 is updated to version 0.3.7. ** The included copy of OpenCDK is updated to version 0.5.11. ** Fix the filename of the *.def file on Windows after library version bump. ** Separated the gnulib directory into one for LGPL modules and one for GPL. This allows the GPL'd part of GnuTLS to take advantage of the GPL'd gnulib modules. Earlier we could only use the LGPL'ed module from gnulib, because two gnulib directories in the same project didn't work. ** API and ABI modifications: No changes since last version. * Version 1.5.2 (released 2006-10-03) ** Decrement the shared library version back to 13 (as in the 1.4.x branch). Note that if you installed 1.5.0 or 1.5.1, they will have a higher shared library version than this version, so you'll have to remove them and possibly relink your applications. The reason for this is that no API/ABI changes have been made since the 1.4.x branch, and that incrementing the shared library version was a mistake. Reported by Andreas Metzler . ** Fix off-by-one error when computing length to malloc. The code is used by gnutls_openpgp_add_keyring_file and gnutls_openpgp_add_keyring_mem. Reported by "Adam Langley" . ** Add version script for the GnuTLS C++ library. Reported by Andreas Metzler . ** Fix the C++ compiler detection logic. Reported by Andreas Metzler . ** Update of gnulib files. ** API and ABI modifications: No changes since last version. * Version 1.5.1 (released 2006-09-21) ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's ** Crypto 06 rump session attack. In particular, we check that the digestAlgorithm.parameters field is missing or empty, to avoid that it can contain "garbage" that may be used to alter the numeric properties of the signature. See (which is not exactly the same as the problem we fix here). Reported by Yutaka OIWA . See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more up to date information. ** Add self test to test for above flaw. ** Fix gnutls-cli-debug regarding resume support detection. Earlier, if the session-id from the server had a length of 0, it would indicate the the server supports resumption, which isn't the case. Reported by Kataja Kai . ** Fix building of examples on FreeBSD by including netinet/in.h. Reported by Roman Bogorodskiy . ** Fix certtool bug that caused the private key to not be loaded when generating a certificate with --load-request, which in turn triggered another unrelated bug in gnutls_x509_crt_sign2 (also fixed). Reported by Sascha Ziemann . ** gnutls-cli and gnutls-serv works on Windows. The problem was the select() call that doesn't work on file descriptors (stdin) on Windows. We borrowed some code from plibc to solve this. It appears to be somewhat unreliable though. ** Autoconf 2.60 is now used. ** API and ABI modifications: No changes since last version. * Version 1.5.0 (released 2006-08-13) ** Change SRP and Cert-Type extensions to match IANA registry. ** Fixed bug in OpenPGP authentication handshake. ** Improvements for building under MinGW. Provides internal inet_ntop and inet_pton functions and arpa/inet.h header. Calls WSAStartup and WSACleanup in gnutls_global_init and gnutls_global_deinit, respectively. Loads getaddrinfo and getnameinfo at run-time from ws2_32.dll, and falls back on a simple replacement if it is not available. Builds the library with -mms-bitfields -Wl,--enable-runtime-pseudo-reloc. Links with --output-def, to create *.def files, which are installed. ** The examples now (conditionally) include config.h and link to gnulib. No other source changes were necessary, so the examples should continue to be possible to use stand-alone without any autoconf or gnulib stuff. ** Added C++ header "gnutlsxx.h" and library "libgnutlsxx". You may unconditionally disable it with --disable-cxx. See includes/gnutls/gnutlsxx.h and lib/gnutlsxx.cpp for the implementation. ** Made command line tool '--version' behave according to GNU Standards. This enables 'make distcheck' to succeed. ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support. ** Make --without-included-libtasn1 work. Reported by Daniel Black . ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic. See http://www.gnu.org/software/gnutls/security.html regardging GNUTLS-SA-2006-2 for more up to date information. Reported by satyakumar . ** API and ABI modifications: No changes since last version. * Version 1.4.5 (released 2006-11-06) ** When a GnuTLS server receive a SSLv2 Client Hello for an unknown TLS ** version, try to negotiate the highest version support by the GnuTLS server, ** instead of the lowest. Reported by . ** Fix typo in doc/examples/ex-serv-pgp.c. Reported by Adam Langley" . ** API and ABI modifications: No changes since last version. * Version 1.4.4 (released 2006-09-12) ** Relax the test that caught signatures that exploit the variant of ** Bleichenbacher's Crypto 06 rump session attack on our ** verification logic flaw. In particular, we now permit the digestAlgorithm.parameters field to be present but empty, whereas in 1.4.3 we actually checked that the field was absent. ** Revert the removal of debug information for the GNUTLS-SA-2006-3 problem. The messages are only printed in debug mode, which is not recommended for normal use, and thus logging this situation cannot be abused as an oracle in typical recommended situations. ** API and ABI modifications: No changes since last version. * Version 1.4.3 (released 2006-09-08) ** Fix PKCS#1 verification to avoid a variant of Bleichenbacher's ** Crypto 06 rump session attack. In particular, we check that the digestAlgorithm.parameters field is empty, to avoid that it can contain "garbage" that may be used to alter the numeric properties of the signature. See (which is not exactly the same as the problem we fix here). Reported by Yutaka OIWA . See GNUTLS-SA-2006-4 on http://www.gnutls.org/security.html for more up to date information. ** Fix PKCS#1 decryption to avoid Bleichenbacher's Crypto 98 attack. See . Reported by Werner Koch . See GNUTLS-SA-2006-3 on http://www.gnutls.org/security.html for more up to date information. ** Fix crash in gnutls_x509_crt_sign2 if passed a NULL issuer_key. ** API and ABI modifications: No changes since last version. * Version 1.4.2 (released 2006-08-12) ** Fix a crash (strcmp() on a NULL value) in the certificate verification logic. This can happen if you call gnutls_certificate_verify_peers2 and have a certain mix of local CA certificates and the peer send special certificates, that together trigger certain behaviour. It is not known at this point whether the crash can be triggered without the special local CA certificate, and thus turn this into a remote crash of clients that verify server certificates when they talk to a server with the special server certificate. See GNUTLS-SA-2006-2 on http://www.gnu.org/software/gnutls/security.html for more up to date information. Reported by satyakumar . ** Change SRP and Cert-Type extensions to match IANA registry. ** OpenCDK updated to 0.5.9 to fix some problems with OpenPGP support. ** Make --without-included-libtasn1 work. Reported by Daniel Black . ** API and ABI modifications: No changes since last version. * Version 1.4.1 (released 2006-06-14) ** Replaced inactive ifdefs to enable openpgp support in test programs. ** Fixed bug in OpenPGP authentication handshake. ** Fixed typographical in man pages. ** Build fixes of the manual. ** Added Swedish translation. ** API and ABI modifications: No changes since last version. * Version 1.4.0 (released 2006-05-15) ** Remove GnuTLS 0.8.x compatibility functions. ** The libgcrypt RNG is initialized in gnutls_global_init(). ** TLS/IA API changes from Emile van Bergen. A dummy credential structure is not needed now, if you wish to use the low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on a session. ** The self-tests are now run under valgrind, if it is installed. ** Libtasn1 is updated to 0.3.4, and that version is now required. ** The command line tools now use getaddrinfo and support IPv6. ** API and ABI modifications: _gnutls_x509_get_raw_crt_activation_time, _gnutls_x509_get_raw_crt_expiration_time: Removed. gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable. gnutls_ia_enable: Added. * Version 1.3.5 (released 2006-03-08) ** Error messages are now translated using GNU Gettext. ** The function gnutls_x509_crt_to_xml now return an internal error. This means that the code to convert X.509 certificates to XML format does not work any more. The reason is that the function called libtasn1 internal functions. It seems unclean for libtasn1 to export the APIs needed here. Instead it would be better to implement XML support inside libtasn1 properly. If you need this functionality strongly, please consider looking into implementing this suggested approach instead. As a workaround, you may also modify lib/x509/xml.c (change '#if 1' to '#if 0') and build using --with-included-libtasn1. ** Libraries are now built with libtool's -no-undefined. This helps producing libraries for Windows using mingw32. ** Doc fixes to explain that gnutls_record_send can block. ** Libtasn1 0.3.1 or later is now required. The include copy has been updated too. ** gnutls-cli can now recognize services and port numbers with the -p option. ** API and ABI modifications: No changes since last version. * Version 1.3.4 (released 2006-02-09) ** Fix read of out bounds bug in DER parser. Reported by Evgeny Legerov , and debugging help from Protover SSL. Libtasn1 0.2.18 is now required, which contains the previous bug fix. The included libtasn1 version in GnuTLS has been updated. ** Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no longer invalidate a session if the underlying send fails, but it will prevent future writes. That is to allow reading the already received data. Patches and bug reports by Yoann Vandoorselaere ** Corrected bugs in gnutls_certificate_set_x509_crl() and gnutls_certificate_set_x509_trust(), that caused memory corruption if more than one certificates were added. Report and patch by Max Kellermann. ** Fix build problems of OpenCDK on AIX. Thanks to "Heiden, John" . ** API and ABI modifications: No changes since last version. * Version 1.3.3 (released 2006-01-12) ** New API to access the TLS master secret. When possible, you should use the TLS PRF functions instead. Suggested by Jouni Malinen . ** Improved handling when multiple libraries use GnuTLS at the same time. Now gnutls_global_init() can be called multiple times, and gnutls_global_deinit() will only deallocate the structure when it has been called as many times as gnutls_global_init() was called. ** Added a self test of TLS resume functionality. ** Fix crash in TLS resume code, caused by TLS/IA changes. ** Documentation fixes about thread unsafety, prompted by ** discussion with bryanh@giraffe-data.com (Bryan Henderson). In particular, gnutls_global_init() and gnutls_global_deinit() are not thread safe. Careful callers may want to protect the call using a mutex. The problem could also be ignored, which would cause a memory leak under rare conditions when two threads invoke the function roughly at the same time. ** Add 'const' keywords in various places, from Frediano ZIGLIO. ** The code was indented again, including the external header files. ** API and ABI modifications: New functions to retrieve the master secret value: gnutls_session_get_master_secret Add a 'const' keyword to existing API: gnutls_x509_crq_get_challenge_password * Version 1.3.2 (released 2005-12-15) ** GnuTLS now support TLS Inner application (TLS/IA). This is per draft-funk-tls-inner-application-extension-01. This functionality is added to libgnutls-extra, so it is licensed under the GNU General Public License. ** New APIs to access the TLS Pseudo-Random-Function (PRF). The PRF is used by some protocols building on TLS, such as EAP-PEAP and EAP-TTLS. One function to access the raw PRF and one to access the PRF seeded with the client/server random fields are provided. Suggested by Jouni Malinen . ** New APIs to acceess the client and server random fields in a session. These fields can be useful by protocols using TLS. Note that these fields are typically used as input to the TLS PRF, and if this is your intended use, you should use the TLS PRF API that use the client/server random field directly. Suggested by Jouni Malinen . ** Internal type cleanups. The uint8, uint16, uint32 types have been replaced by uint8_t, uint16_t, uint32_t. Gnulib is used to guarantee the presence of correct types on platforms that lack them. The uint type have been replaced by unsigned. ** API and ABI modifications: New functions to invoke the TLS Pseudo-Random-Function (PRF): gnutls_prf gnutls_prf_raw New functions to retrieve the session's client and server random values: gnutls_session_get_server_random gnutls_session_get_client_random New function, to perform TLS/IA handshake: gnutls_ia_handshake New function to decide whether to do a TLS/IA handshake: gnutls_ia_handshake_p New functions to allocate a TLS/IA credential: gnutls_ia_allocate_client_credentials gnutls_ia_free_client_credentials gnutls_ia_allocate_server_credentials gnutls_ia_free_server_credentials New functions to handle the AVP callback: gnutls_ia_set_client_avp_function gnutls_ia_set_client_avp_ptr gnutls_ia_get_client_avp_ptr gnutls_ia_set_server_avp_function gnutls_ia_set_server_avp_ptr gnutls_ia_get_server_avp_ptr New functions, to toggle TLS/IA application phases: gnutls_ia_require_inner_phase New function to mix session keys with inner secret: gnutls_ia_permute_inner_secret Low-level API (used internally by gnutls_ia_handshake): gnutls_ia_endphase_send gnutls_ia_send gnutls_ia_recv New functions that can be used after successful TLS/IA negotiation: gnutls_ia_generate_challenge gnutls_ia_extract_inner_secret Enum type with TLS/IA modes: gnutls_ia_mode_t Enum type with TLS/IA packet types: gnutls_ia_apptype_t Enum values for TLS/IA alerts: GNUTLS_A_INNER_APPLICATION_FAILURE GNUTLS_A_INNER_APPLICATION_VERIFICATION New error codes, to signal when an application phase has finished: GNUTLS_E_WARNING_IA_IPHF_RECEIVED GNUTLS_E_WARNING_IA_FPHF_RECEIVED New error code to signal TLS/IA verify failure: GNUTLS_E_IA_VERIFY_FAILED * Version 1.3.1 (released 2005-12-08) ** Support for DHE-PSK cipher suites has been added. This method offers perfect forward secrecy. ** Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to Otto Maddox and Nozomu Ando . ** Corrected a bug in certtool for 64 bit machines. Reported by Max Kellermann . ** New function to set a X.509 private key and certificate pairs, and/or CRLs, from an PKCS#12 file, suggested by Emile van Bergen . The integrity of the PKCS#12 file is protected through a password based MAC; public-key based signatures for integrity protection are not supported. PKCS#12 bags may be encrypted using password derived symmetric keys, public-key based encryption is not supported. The PKCS#8 keys may be encrypted using passwords. The API use the same password for all operations. We believe that any more flexibility create too much complexity that would hurt overall security, but may add more PKCS#12 related APIs if real-world experience indicate otherwise. ** gnutls_x509_privkey_import_pkcs8 now accept unencrypted PEM PKCS#8 keys, reported by Emile van Bergen . This will enable "certtool -k -8" to parse those keys. ** Certtool now generate keys in unencrypted PKCS#8 format for empty passwords. Use "certtool -p -8" and press press enter at the prompt. Earlier, certtool would have encrypted the key using an empty password. ** Certtool now accept --password for --key-info and encrypted PKCS#8 keys. Earlier it would have prompted the user for it, even if --password was supplied. ** Added self test of PKCS#8 parsing. Unencrypted and encrypted (pbeWithSHAAnd3-KeyTripleDES-CBC and pbeWithSHAAnd40BitRC2-CBC) formats are tested. The test is in tests/pkcs8. ** API and ABI modifications: New function to set X.509 credentials from a PKCS#12 file: gnutls_certificate_set_x509_simple_pkcs12_file New gnutls_kx_algorithm_t enum type: GNUTLS_KX_DHE_PSK New API to return session data (basically same as gnutls_session_get_data): gnutls_session_get_data2 New API to set PSK Diffie-Hellman parameters: gnutls_psk_set_server_dh_params * Version 1.3.0 (2005-11-15) ** Support for TLS Pre-Shared Key (TLS-PSK) ciphersuites have been added. This add several new APIs, see below. Read the updated manual for more information. A new self test "pskself" has been added, that will test this functionality. ** The session resumption data are now system independent. ** The code has been re-indented to conform to the GNU coding style. ** Removed the RIPEMD ciphersuites. ** Added a discussion of the internals of gnutls in manual. ** Fixes for Tru64 UNIX 4.0D that lack MAP_FAILED, from Albert Chin. ** Remove trailing comma in enums, for IBM C v6, from Albert Chin. ** Make sure config.h is included first in a few files, from Albert Chin. ** Don't use C++ comments ("//") as they are invalid, from Albert Chin. ** Don't install SRP programs and man pages if --disable-srp-authentication, from Albert Chin. ** API and ABI modifications: New gnutls_kx_algorithm_t key exchange type: GNUTLS_KX_PSK New gnutls_credentials_type_t credential type: GNUTLS_CRD_PSK New credential types: gnutls_psk_server_credentials_t gnutls_psk_client_credentials_t New functions to allocate PSK credentials: gnutls_psk_allocate_client_credentials gnutls_psk_free_client_credentials gnutls_psk_free_server_credentials gnutls_psk_allocate_server_credentials New enum type for PSK key flags: gnutls_psk_key_flags New function prototypes for credential callback: gnutls_psk_client_credentials_function gnutls_psk_server_credentials_function New function to set PSK username and key: gnutls_psk_set_client_credentials New function to set PSK passwd file: gnutls_psk_set_server_credentials_file New function to extract PSK user in server: gnutls_psk_server_get_username New functions to set PSK callback: gnutls_psk_set_server_credentials_function gnutls_psk_set_client_credentials_function Use size_t instead of int for output size parameter: gnutls_srp_base64_encode gnutls_srp_base64_decode * Version 1.2.11 (2006-05-11) - The function gnutls_x509_crt_to_xml is not supported any more, and return an internal error. The reason is that the function called internal libtasn1 functions which are no longer exported from libtasn1. - Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1. - Updated gnulib compatibility files. - Fixed _gnutls_x509_get_raw_crt_expiration_time and _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors. - API and ABI modifications: No changes since last version. * Version 1.2.10 (2006-02-09) - Fix read out bounds bug in DER parser.

Report and patch by Max Kellermann. - Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no longer invalidate a session if the underlying send fails, but it will prevent future writes. That is to allow reading the already received data. Patches and bug reports by Yoann Vandoorselaere * Version 1.2.9 (2005-11-07) - Documentation was updated and improved. - RSA-MD2 is now supported for verifying digital signatures. - Due to cryptographic advances, verifying untrusted X.509 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a GNUTLS_CERT_INSECURE_ALGORITHM verification output. For applications that must remain interoperable, you can use the GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5 flags when verifying certificates. Naturally, this is not recommended default behaviour for applications. To enable the broken algorithms, call gnutls_certificate_set_verify_flags with the proper flag, to change the verification mode used by gnutls_certificate_verify_peers2. - Make it possible to send empty data through gnutls_record_send, to align with the send(2) API. - Some changes in the certificate receiving part of handshake to prevent some possible errors with non-blocking servers. - Added numeric version symbols to permit simple CPP-based feature tests, suggested by Daniel Stenberg . - The (experimental) low-level crypto alternative to libgcrypt used earlier (Nettle) has been replaced with crypto code from gnulib. This leads to easier re-use of these components in other projects, leading to more review and simpler maintenance. The new configure parameter --with-builtin-crypto replace the old --with-nettle, and must be used if you wish to enable this functionality. See README under "Experimental" for more information. Internally, GnuTLS has been updated to use the new "Generic Crypto" API in gl/gc.h. The API is similar to the old crypto/gc.h, because the gnulib code were based on GnuTLS's gc.h. - Fix compiler warning in the "anonself" self test. - API and ABI modifications: gnutls_x509_crt_list_verify: Added 'const' to prototype in . This doesn't reflect a change in behaviour, so we don't break backwards compatibility. GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value. GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value. GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2, GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values. Use when calling gnutls_x509_crt_list_verify, gnutls_x509_crt_verify, or gnutls_certificate_set_verify_flags. GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value, used when broken signature algorithms is used (currently RSA-MD2/MD5). LIBGNUTLS_VERSION_MAJOR, LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS version number, can be used for feature existence tests. * Version 1.2.8 (2005-10-07) - Libgcrypt 1.2.2 is required to fix a bug for forking GnuTLS servers. - Don't install the auxilliary libexamples library used by the examples in doc/examples/ on "make install", report and tiny patch from Thomas Klausner . - If you pass a X.509 CA or PGP trust database to the command line tool, it will now abort the connection if the server certificate validation fails.
