The GnuPG team is pleased to announce the availability of a new release
of GnuPG: version 2.1.21. See below for a list of new features and bug
Note: This release fixes a keyring corruption bug introduced
with last release. Users of 2.1.20, who are using the
old "pubring.gpg" file to store their public keys, are
asked to update to this new release.
The GNU Privacy Guard (GnuPG) is a complete and free implementation
of the OpenPGP standard which is commonly abbreviated as PGP.
GnuPG allows to encrypt and sign data and communication, features a
versatile key management system as well as access modules for public key
directories. GnuPG itself is a command line tool with features for easy
integration with other applications. A wealth of frontend applications
and libraries making use of GnuPG are available. As an Universal Crypto
Engine GnuPG provides support for S/MIME and Secure Shell in addition to
GnuPG is Free Software (meaning that it respects your freedom). It can
be freely used, modified and distributed under the terms of the GNU
General Public License.
Noteworthy changes in version 2.1.21
* gpg,gpgsm: Fix corruption of old style keyring.gpg files. This
bug was introduced with version 2.1.20. Note that the default
pubring.kbx format was not affected.
* gpg,dirmngr: Removed the skeleton config file support. The
system's standard methods for providing default configuration
files should be used instead.
* w32: The Windows installer now allows installion of GnuPG without
* gpg: Fixed import filter property match bug.
* scd: Removed Linux support for Cardman 4040 PCMCIA reader.
* scd: Fixed some corner case bugs in resume/suspend handling.
* Many minor bug fixes and code cleanup.
A detailed description of the changes found in this 2.1 branch can be
found at <https://gnupg.org/faq/whats-new-in-2.1.html>.
Getting the Software
Please follow the instructions found at <https://gnupg.org/download/> or
GnuPG 2.1.21 may be downloaded from one of the GnuPG mirror sites or
direct from its primary FTP server. The list of mirrors can be found at
<https://gnupg.org/download/mirrors.html>. Note that GnuPG is not
available at ftp.gnu.org.
The GnuPG source code compressed using BZIP2 and its OpenPGP signature
are available here:
or via FTP:
An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:
or via FTP:
The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix. The Windows installer comes with
TOFU support, many translations, support for Tor, and support for HKPS
and the Web Key Directory.
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 version of GnuPG installed, you can simply
verify the supplied signature. For example to verify the signature
of the file gnupg-2.1.21.tar.bz2 you would use this command:
gpg --verify gnupg-2.1.21.tar.bz2.sig gnupg-2.1.21.tar.bz2
This checks whether the signature file matches the source file.
You should see a message indicating that the signature is good and
made by one or more of the release signing keys. Make sure that
this is a valid key, either by matching the shown fingerprint
against a trustworthy list of valid release signing keys or by
checking that the key has been signed by trustworthy other keys.
See the end of this mail for information on the signing keys.
* If you are not able to use an existing version of GnuPG, you have
to verify the SHA-1 checksum. On Unix systems the command to do
this is either "sha1sum" or "shasum". Assuming you downloaded the
file gnupg-2.1.21.tar.bz2, you run the command like this:
and check that the output matches the next line:
This version of GnuPG has support for 26 languages with Chinese, Czech,
French, German, Japanese, Norwegian, Russian, and Ukrainian being almost
completely translated. Due to expected changes in forthcoming releases
some strings pertaining to the TOFU code are not yet translated.
If you used GnuPG in the past you should read the description of
changes and new features at doc/whats-new-in-2.1.txt or online at
The file gnupg.info has the complete user manual of the system.
Separate man pages are included as well but they have not all the
details available as are 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.
