We are pleased to announce the availability of a new stable GnuPG-2
release: Version 2.0.16.
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
GnuPG-2 has a different architecture than GnuPG-1 (e.g. 1.4.10) 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.
* If the agent's --use-standard-socket option is active, all tools
try to start and daemonize the agent on the fly. In the past this
was only supported on W32; on non-W32 systems the new configure
option --use-standard-socket may now be used to use this feature by
* The gpg-agent commands KILLAGENT and RELOADAGENT are now available
on all platforms.
* Minor bug fixes.
Getting the Software
Please follow the instructions found at http://www.gnupg.org/download/
or read on:
GnuPG 2.0.16 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 source compressed using BZIP2 and OpenPGP signature.
A patch file to upgrade a 2.0.15 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-2.0.16.tar.bz2 you would use this command:
gpg --verify gnupg-2.0.16.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 --recv-key 1CE0C630
The distribution key 1CE0C630 is signed by the well known key
5B0358A2. If you get an key expired message, you should retrieve a
fresh copy as the expiration date might have been prolonged.
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-2.0.16.tar.bz2, you would run the sha1sum command like this:
and check that the output matches the first line from the
GnuPG comes with support for 27 languages. Due to a lot of new and
changed strings many translations are not entirely complete. Jedi,
Maxim Britov, Jaime Suárez and Nilgün Belma Bugüner have been kind
enough to go over their translations and thus the Chinese, German,
Russian, Spanish, and Turkish translations are pretty much complete.
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
The manual is also available online in HTML format at
and in Portable Document Format at
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

testing, coding, translating, suggesting, auditing, administering the
servers, spreading the word or answering questions on the mailing
