Hello!

We are pleased to announce the availability of a new stable GnuPG-2 release: Version 2.0.17.

The GNU Privacy Guard (GnuPG) is GNU's tool for secure communication and data storage. It can be used to encrypt data, create digital signatures, help authenticating using Secure Shell and to provide a framework for public key cryptography. It includes an advanced key management facility and is compliant with the OpenPGP and S/MIME standards.

GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.11) in that it splits up functionality into several modules. However, both versions may be installed alongside without any conflict. In fact, the gpg version from GnuPG-1 is able to make use of the gpg-agent as included in GnuPG-2 and allows for seamless passphrase caching. The advantage of GnuPG-1 is its smaller size and the lack of dependency on other modules at run and build time. We will keep maintaining GnuPG-1 versions because they are very useful for small systems and for server based applications requiring only OpenPGP support.

GnuPG is distributed under the terms of the GNU General Public License (GPL version 3). GnuPG-2 works best on GNU/Linux or *BSD systems.

What's New

• Allow more hash algorithms with the OpenPGP v2 card.

• The gpg-agent now tests for a new gpg-agent.conf on a HUP.

• Fixed output of "gpgconf --check-options".

• Fixed a bug where Scdaemon sends a signal to Gpg-agent running in non-daemon mode.

• Fixed TTY management for pinentries and session variable update problem.

• Minor bug fixes.

Getting the Software

Please follow the instructions found at http://www.gnupg.org/download/ or read on:

GnuPG 2.0.17 may be downloaded from one of the GnuPG mirror sites or direct from ftp://ftp.gnupg.org/gcrypt/gnupg/ . The list of mirrors can be found at http://www.gnupg.org/mirrors.html . Note, that GnuPG is not available at ftp.gnu.org.

On the FTP server and its mirrors you should find the following files in the gnupg/ directory:

gnupg-2.0.17.tar.bz2 (3904k) gnupg-2.0.17.tar.bz2.sig

  GnuPG source compressed using BZIP2 and OpenPGP signature.

gnupg-2.0.16-2.0.17.diff.bz2 (75k)

  A patch file to upgrade a 2.0.16 GnuPG source tree.  This patch
  does not include updates of the language files.

Note, that we don't distribute gzip compressed tarballs for GnuPG-2.

Checking the Integrity

In order to check that the version of GnuPG which you are going to install is an original and unmodified one, you can do it in one of the following ways:

• If you already have a trusted version of GnuPG installed, you can simply check the supplied signature. For example to check the signature of the file gnupg-2.0.17.tar.bz2 you would use this command:

  gpg --verify gnupg-2.0.17.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. Note, that you can retrieve the signing key using the command

  finger wk ,at' g10code.com

  or using a keyserver like

  gpg --keyserver keys.gnupg.net --recv-key 4F25E3B6

  The distribution key 4F25E3B6 is signed by the well known key 1E42B367.

  NEVER USE A GNUPG VERSION YOU JUST DOWNLOADED TO CHECK THE INTEGRITY OF THE SOURCE - USE AN EXISTING GNUPG INSTALLATION!

• If you are not able to use an old version of GnuPG, you have to verify the SHA-1 checksum. Assuming you downloaded the file gnupg-2.0.17.tar.bz2, you would run the sha1sum command like this:

  sha1sum gnupg-2.0.17.tar.bz2

  and check that the output matches the first line from the following list:

41ef5460417ca0a1131fc730849fe3afd49ad2de gnupg-2.0.17.tar.bz2 ba49d5ab2659bfe6403d52df58722f439e393bbb gnupg-2.0.16-2.0.17.diff.bz2

Internationalization

GnuPG comes with support for 27 languages. Due to a lot of new and changed strings many translations are not entirely complete. Jakub Bogusz, Petr Pisar, Jedi and Daniel Nylander have been kind enough to update their translations on short notice. Thus the Chinese, Czech, German, Polish and Swedish translations are complete.

Documentation

We are currently working on an installation guide to explain in more detail how to configure the new features. As of now the chapters on gpg-agent and gpgsm include brief information on how to set up the whole thing. Please watch the GnuPG website for updates of the documentation. In the meantime you may search the GnuPG mailing list archives or ask on the gnupg-users mailing lists for advise on how to solve problems. Many of the new features are around for several years and thus enough public knowledge is already available. KDE's KMail is the most prominent user of GnuPG-2. In fact it has been developed along with the KMail folks. Mutt users might want to use the configure option "--enable-gpgme" and "set use_crypt_gpgme" in ~/.muttrc to make use of GnuPG-2 to enable S/MIME in addition to a reworked OpenPGP support.

The manual is also available online in HTML format at http://www.gnupg.org/documentation/manuals/gnupg/ and in Portable Document Format at http://www.gnupg.org/documentation/manuals/gnupg.pdf .

Support

Improving GnuPG is costly, but you can help! We are looking for organizations that find GnuPG useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, order extensions or support or more general by donating money to the Free Software movement (e.g. http://www.fsfeurope.org/help/donate.en.html).

Commercial support contracts for GnuPG are available, and they help finance continued maintenance. g10 Code GmbH, a Duesseldorf based company owned and headed by GnuPG's principal author, is currently funding GnuPG development. We are always looking for interesting development projects.

The GnuPG service directory is available at:

Thanks

We have to thank all the people who helped with this release, be it testing, coding, translating, suggesting, auditing, administering the servers, spreading the word or answering questions on the mailing lists.

Happy Hacking,

The GnuPG Team
