We are proud to announce a new stable GnuTLS release: Version 2.8.6. GnuTLS is a modern C library that implements the standard network security protocol Transport Layer Security (TLS), for use by network applications. GnuTLS is developed for GNU/Linux, but works on many Unix-like systems and comes with a binary installer for Windows.
The GnuTLS library is distributed under the terms of the GNU Lesser General Public License version 2.1 (or later). The "extra" GnuTLS library (which contains TLS/IA support, LZO compression and Libgcrypt FIPS-mode handler), the OpenSSL compatibility library, the self tests and the command line tools are all distributed under the GNU General Public License version 3.0 (or later). The manual is distributed under the GNU Free Documentation License version 1.3 (or later). The project page of the library is available at: http://www.gnu.org/software/gnutls/ What's New ========== ** libgnutls: For CSRs, don't null pad integers for RSA/DSA value. VeriSign rejected CSRs with this padding. Reported by Wilankar Trupti <trupti.wilan...@hp.com> and Boyan Kasarov <bkasa...@gmail.com>. Note: As a side effect of this change, the "public key identifier" value computed for a certificate using this version of GnuTLS will be different from values computed using earlier versions of GnuTLS. ** libgnutls: For CSRs on DSA keys, don't add DSA parameters to the ** optional SignatureAlgorithm parameter field. VeriSign rejected these CSRs. They are stricly speaking not needed since you need the signer's certificate to verify the certificate signature anyway. Reported by Wilankar Trupti <trupti.wilan...@hp.com> and Boyan Kasarov <bkasa...@gmail.com>. ** libgnutls: When checking openpgp self signature also check the signatures ** of all subkeys. Ilari Liusvaara noticed and reported the issue and provided test vectors as well. ** libgnutls: Cleanups and several bug fixes. Found by Steve Grubb and Tomas Mraz. ** Link libgcrypt explicitly to certtool, gnutls-cli, gnutls-serv. ** Fix --disable-valgrind-tests. Reported by Ingmar Vanhassel in <https://savannah.gnu.org/support/?107029>. ** examples: Use the new APIs for printing X.509 certificate information. ** Fix build failures on Solaris. Thanks to Dagobert Michelsen <d...@opencsw.org>. ** i18n: Updated Czech, Dutch, French, Polish, Swedish and Vietnamese ** translations. Added Simplified Chinese translation. ** API and ABI modifications: No changes since last version. Getting the Software ==================== GnuTLS may be downloaded from one of the mirror sites or direct from <ftp://ftp.gnu.org/gnu/gnutls/>. The list of mirrors can be found at <http://www.gnu.org/software/gnutls/download.html>. Here are the BZIP2 compressed sources (6.2MB): ftp://ftp.gnu.org/gnu/gnutls/gnutls-2.8.6.tar.bz2 http://ftp.gnu.org/gnu/gnutls/gnutls-2.8.6.tar.bz2 Here are OpenPGP detached signatures signed using key 0xB565716F: ftp://ftp.gnu.org/gnu/gnutls/gnutls-2.8.6.tar.bz2.sig http://ftp.gnu.org/gnu/gnutls/gnutls-2.8.6.tar.bz2.sig Note, that we don't distribute gzip compressed tarballs. In order to check that the version of GnuTLS which you are going to install is an original and unmodified one, you should verify the OpenPGP signature. You can use the command gpg --verify gnutls-2.8.6.tar.bz2.sig This checks whether the signature file matches the source file. You should see a message indicating that the signature is good and made by that signing key. Make sure that you have the right key, either by checking the fingerprint of that key with other sources or by checking that the key has been signed by a trustworthy other key. The signing key can be identified with the following information: pub 1280R/B565716F 2002-05-05 [expires: 2011-03-30] Key fingerprint = 0424 D4EE 81A0 E3D1 19C6 F835 EDA2 1E94 B565 716F uid Simon Josefsson <j...@extundo.com> uid Simon Josefsson <si...@josefsson.org> sub 1280R/4D5D40AE 2002-05-05 [expires: 2011-03-30] The key is available from: http://josefsson.org/key.txt dns:b565716f.josefsson.org?TYPE=CERT Alternatively, after successfully verifying the OpenPGP signature of this announcement, you could verify that the files match the following checksum values. The values are for SHA-1 and SHA-224 respectively: bff911d4fd7389aa6698a644b3748eb2d23715bc gnutls-2.8.6.tar.bz2 a6b36fa1926a7fd3cb68746446c29dc1cbef0cc6bcfd25877fde64ad gnutls-2.8.6.tar.bz2 Documentation ============= The manual is available online at: http://www.gnu.org/software/gnutls/documentation.html In particular the following formats are available: HTML: http://www.gnu.org/software/gnutls/manual/html_node/index.html PDF: http://www.gnu.org/software/gnutls/manual/gnutls.pdf For developers there is a GnuTLS API reference manual formatted using the GTK-DOC tools: http://www.gnu.org/software/gnutls/reference/gnutls-gnutls.html For developers interested in improving code quality, we publish Cyclomatic code complexity charts that help you find code that may need review and improvements: http://www.gnu.org/software/gnutls/cyclo/ Also useful are code coverage charts which indicate parts of the source code that needs to be tested better by the included self-tests: http://www.gnu.org/software/gnutls/coverage/ Community ========= If you need help to use GnuTLS, or want to help others, you are invited to join our help-gnutls mailing list, see: http://lists.gnu.org/mailman/listinfo/help-gnutls If you wish to participate in the development of GnuTLS, you are invited to join our gnutls-dev mailing list, see: http://lists.gnu.org/mailman/listinfo/gnutls-devel Windows installer ================= GnuTLS has been ported to the Windows operating system, and a binary installer is available.

We welcome the addition of more translations. Support ======= Improving GnuTLS is costly, but you can help! We are looking for organizations that find GnuTLS useful and wish to contribute back. You can contribute by reporting bugs, improve the software, or donate money or equipment. Commercial support contracts for GnuTLS are available, and they help finance continued maintenance. Simon Josefsson Datakonsult AB, a Stockholm based privately held company, is currently funding GnuTLS maintenance. We are always looking for interesting development projects. See http://josefsson.org/ for more details. The GnuTLS service directory is available at: http://www.gnu.org/software/gnutls/commercial.html Happy Hacking, Simon
