We are pleased to announce a new stable GnuTLS release: Version 2.0.0. GnuTLS is a modern C library that implement 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 core GnuTLS library is distribute under the terms of the GNU Lesser General Public License version 2.1 (or later). The "extra" GnuTLS libraries -- which contains OpenPGP and TLS/IA support, LZO2 compression, the OpenSSL compatibility library -- and the self tests and command line tools are distributed under the GNU General Public License version 2.0 (or later). The manual is distributed under the GNU Free Documentation License version 1.2 (or later). The project page of the library is available at: http://www.gnutls.org/ http://www.gnu.org/software/gnutls/ http://josefsson.org/gnutls/ What's New ========== The following changes have been made since GnuTLS 1.6: * Support for external RSA/DSA signing for TLS client authentication. This allows you to secure the private key better, for example by using privilege-separation techniques between the private key and the network client/server. * Support for signing X.509 certificates using RSA with SHA-256/384/512. * Experimental support for TLS 1.2 (disabled by default). The TLS 1.2 specification is not finalized yet, but we implement a draft version for testing. * Support for X.509 Proxy Certificates (RFC 3820) * Support for Supplemental handshakes messages (RFC 4680). * Support for TLS authorization extension (draft-housley-tls-authz-extns-07). * Support for the X.509 'otherName' Subject Altnerative Names (for XMPP). * Guile bindings for GnuTLS have been added, thanks to Ludovic Courtès. * Improve logic of gnutls_set_default_priority() which can now be more recommended. * New APIs to enumerate supported algorithms in the library. * New APIs to access X.509 Certificate extension sequentially. * New APIs to print X.509 Certificates and CRLs in human readable formats. * New APIs to extract X.509 Distinguished Names from certificates. * New APIs to handle pathLenConstraint in X.509 Basic Constraints. * Certtool can export more than one certificate to PKCS#12. * Several message translation improvements. * Instructions and improvements to easily set up a HTTPS test server. * Included copies updated to Libtasn1 1.1 and OpenCDK 0.6.4. * Build improvements for Windows, Mac OS X, uClinux, etc. * GnuTLS is now developed in GIT. * Improved manual * Many bugfixes and minor improvements. Getting the Software ==================== GnuTLS may be downloaded from one of the mirror sites or direct from <ftp://ftp.gnutls.org/pub/gnutls/>. The list of mirrors can be found at <http://www.gnu.org/software/gnutls/download.html>. Note, that GnuPG is not available at ftp.gnu.org. Here are the BZIP2 compressed sources (4.6MB): ftp://ftp.gnutls.org/pub/gnutls/gnutls-2.0.0.tar.bz2 http://josefsson.org/gnutls/releases/gnutls-2.0.0.tar.bz2 Here are OpenPGP detached signatures signed using key 0xB565716F: ftp://ftp.gnutls.org/pub/gnutls/gnutls-2.0.0.tar.bz2.sig http://josefsson.org/gnutls/releases/gnutls-2.0.0.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-2.0.0.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: 2008-06-30] Key fingerprint = 0424 D4EE 81A0 E3D1 19C6 F835 EDA2 1E94 B565 716F uid Simon Josefsson <[EMAIL PROTECTED]> uid Simon Josefsson <[EMAIL PROTECTED]> sub 1280R/4D5D40AE 2002-05-05 [expires: 2008-06-30] 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: 985d86cb942b9d79abb5c8966439f23141ad803a gnutls-2.0.0.tar.bz2 9ffe06f0fea815daaf975e39cfa0be38edc74dc8908c05a6870dede0 gnutls-2.0.0.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 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.gnupg.org/mailman/listinfo/gnutls-dev>. Windows installer ================= GnuTLS has been ported to the Windows operating system, and a binary installer is available. The installer contains DLLs for application development, manuals, examples, and source code. The installer consists of libgpg-error 1.5, libgcrypt 1.3.0, libtasn1 1.1, opencdk 0.6.4, and GnuTLS 2.0.0. For more information about GnuTLS for Windows: http://josefsson.org/gnutls4win/ The Windows binary installer and PGP signature: http://josefsson.org/gnutls4win/gnutls-2.0.0.exe (24MB) http://josefsson.org/gnutls4win/gnutls-2.0.0.exe.sig The checksum values for SHA-1 and SHA-224 are: 0261c116f3abdf179c0a93d04488f06b693a128a gnutls-2.0.0.exe d8af39cb1bcecd5c8dc9386c68edb171a20720c88e53f5443abd0bbb gnutls-2.0.0.exe Internationalization ==================== GnuTLS messages have been translated into German, Malay, Polish and Swedish. 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, 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
