User-agent: Gnus/5.13 (Gnus v5.13)


We are pleased to announce the availability of a new stable GnuPG
release: version 2.3.8.  This release comes with a lot of new features
and the binary releases come with the fix for the Libksba vulnerability
CVE-2022-3515 (

What is GnuPG

The GNU Privacy Guard (GnuPG, GPG) is a complete and free implementation
of the OpenPGP and S/MIME standards.

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.  The separate library GPGME provides
a uniform API to use the GnuPG engine by software written in common
programming languages.  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 OpenPGP.

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.

Three different series of GnuPG are actively maintained:

- Version 2.3 is the current stable version with a lot of new features
  compared to 2.2.  This announcement is about the latest release of
  this series.

- Version 2.2 is our LTS (long term support) version and guaranteed to
  be maintained at least until the end of 2024. Only a small subset of
  features from 2.3 has been back-ported to this series.  See

- Version 1.4 is only maintained to allow decryption of very old data
  which is, for security reasons, not anymore possible with other GnuPG

Noteworthy changes in version 2.3.8

  * gpg: Do not consider unknown public keys as non-compliant while
    decrypting.  [T6205]

  * gpg: Avoid to emit a compliance mode line if Libgcrypt is
    non-compliant.  [T6221]

  * gpg: Improve --edit-key setpref command to ease c+p.  [rG1908fa8b83]

    allow to pass the user ID by hash.  [T6126]

  * gpg: Actually show symmetric+pubkey encrypted data as de-vs
    compliant.  Add extra compliance checks for symkey_enc packets.

  * gpg: In de-vs mode use SHA-256 instead of SHA-1 as implicit
    preference.  [T6043]

  * gpgsm: Fix reporting of bad passphrase error during PKCS#11
    import.  [T5713,T6037]

Getting the Software

Please follow the instructions found at <> or
read on:

GnuPG 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
<>.  Note that GnuPG is not
available at

The GnuPG source code compressed using BZIP2 and its OpenPGP signature
are available here: (7465k)

An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here: (4797k)

The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix.

A new release of Gpg4win (version 4.0.4) including this version of GnuPG
is available at

We will shortly announce a Linux AppImage of this version featuring
Kleopatra as graphical user interface.

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-2.3.8.tar.bz2 you would use this command:

     gpg --verify gnupg-2.3.8.tar.bz2.sig gnupg-2.3.8.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-2.3.8.tar.bz2, you run the command like this:

     sha1sum gnupg-2.3.8.tar.bz2

   and check that the output matches the next line:

1f31b7b4c9c9adad97f94ea3acf1aa64c0424bcc  gnupg-2.3.8.tar.bz2
014aa20eb1ac677736d0c2e056adc55304e12679  gnupg-w32-2.3.8_20221013.tar.xz
6cfabadbaf15a27988a11e811e9eabb20077b4ff  gnupg-w32-2.3.8_20221013.exe


This version of GnuPG has support for 26 languages with Chinese
(traditional and simplified), Czech, French, German, Italian,
Japanese, Norwegian, Polish, Russian, Turkish, and Ukrainian
being almost completely translated.

Documentation and Support

The file has the complete reference manual of the system.
Separate man pages are included as well but they miss some of the
details available only in the manual.  The manual is also available
online at

or can be downloaded as PDF at

You may also want to search the GnuPG mailing list archives or ask on
the gnupg-users mailing list for advise on how to solve problems.  Most
of the new features are around for several years and thus enough public
experience is available. has user contributed
information around GnuPG and relate software.

If you are a developer and you need a certain feature for your project,
please do not hesitate to bring it to the gnupg-devel mailing list for


Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH
and has mostly been financed by donations.  Three full-time employed
developers as well as two contractors exclusively work on GnuPG and
closely related software like Libgcrypt, GPGME and Gpg4win.

Fortunately, and this is still not common with free software, we have
now established a way of financing the development while keeping all our
software free and freely available for everyone.  Our model is similar
to the way RedHat manages RHEL and Fedora: Except for the actual binary
of the MSI installer for Windows and client specific configuration
files, all the software is available under the GNU GPL and other Open
Source licenses.  Thus customers may even build and distribute their own
version of the software as long as they do not use our trademark
GnuPG VS-DesktopĀ®.

We like to thank all the nice people who are helping the GnuPG project,
be it testing, coding, translating, suggesting, auditing, administering
the servers, spreading the word, answering questions on the mailing
lists, or helping with donations.

*Thank you all*
