[Announce] GnuPG 2.0.19 released
We are pleased to announce the availability of a new stable GnuPG-2
release: Version 2.0.19.
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. 1.4.12) 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
(GPLv3+). GnuPG-2 works best on GNU/Linux and *BSD systems but is
also available for other Unices, Microsoft Windows and Mac OS X.
What's New in 2.0.19
* GPG now accepts a space separated fingerprint as a user ID. This
allows to copy and paste the fingerprint from the key listing.
* GPG now uses the longest key ID available. Removed support for the
original HKP keyserver which is not anymore used by any site.
* Rebuild the trustdb after changing the option --min-cert-level.
* Ukrainian translation.
* Honor option --cert-digest-algo when creating a cert.
* Emit a DECRYPTION_INFO status line.
* Improved detection of JPEG files.
Getting the Software
Please follow the instructions found at http://www.gnupg.org/download/
or read on:
GnuPG 2.0.19 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 2.0.18 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-2.0.19.tar.bz2 you would use this command:
gpg --verify gnupg-2.0.19.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
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-2.0.19.tar.bz2, you would run the sha1sum command like this:
and check that the output matches the first line from the
The file gnupg.info has the complete user manual of the system.
Separate man pages are included as well; however they have not all the
details available in the manual. It is also possible to read the
complete manual online in HTML format at
or in Portable Document Format at
The chapters on gpg-agent, gpg and gpgsm include information on how
to set up the whole thing. You may also want 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.
Almost all mail clients support GnuPG-2. Mutt users may want to use
the configure option "--enable-gpgme" during build time and put a "set
use_crypt_gpgme" in ~/.muttrc to enable S/MIME support along with the
reworked OpenPGP support.
Please consult the archive of the gnupg-users mailing list before
reporting a bug <http://gnupg.org/documentation/mailing-lists.html>.
We suggest to send bug reports for a new release to this list in favor
of filing a bug at <http://bugs.gnupg.org>. We also have a dedicated
service directory at:
Maintaining and improving GnuPG is costly. For more than 10 years
now, g10 Code, a German company owned and headed by GnuPG's principal
author Werner Koch, is bearing the majority of these costs. To help
them carry on this work, they need your support. Please consider to

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
