We are pleased to announce the availability of a new GnuPG release:
version 2.2.24. This is maintenace release fixing some long standing
bugs. See below for details.
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.
Noteworthy changes in version 2.2.24
* Allow Unicode file names on Windows almost everywhere. Note that
it is still not possible to use Unicode strings on the command
line. This change also fixes a regression in 2.2.22 related to
non-ascii file names. [#5098]
* Fix localized time printing on Windows. [#5073]
* gpg: New command --quick-revoke-sig. [#5093]
* gpg: Do not use weak digest algos if selected by recipient
preference during sign+encrypt. [4c181d51a6]
* gpg: Switch to AES256 for symmetric encryption in de-vs mode.
* gpg: Silence weak digest warnings with --quiet. [#4893]
* gpg: Print new status line CANCELED_BY_USER for a cancel during
symmetric encryption. [f05d1772c4]
* gpg: Fix the encrypt+sign hash algo preference selection for
ECDSA. This is in particular needed for keys created from
existing smartcard based keys. [aeed0b93ff]
* agent: Fix secret key import of GnuPG 2.3 generated Ed25519 keys.
* agent: Keep some permissions of private-keys-v1.d. [#2312]
* dirmngr: Align sks-keyservers.netCA.pem use between ntbtls and
gnutls builds. [e4f3b74c91]
* dirmngr: Fix the pool keyserver case for a single host in the
* scd: Fix the use case of verify_chv2 by CHECKPIN. [61aea64b3c]
* scd: Various improvements to the ccid-driver. [#4616,#5065]
* scd: Minor fixes for Yubikey [25bec16d0b]
* gpgconf: New option --show-versions.
* w32: Install gpg-check-pattern and example profiles. Install
Windows subsystem variant of gpgconf (gpgconf-w32).
* i18n: Complete overhaul and completion of the Italian translation.
Thanks to Denis Renzi.
* Require Libgcrypt 1.8 because 1.7 has long reached end-of-life.
Getting the Software
Please follow the instructions found at <https://gnupg.org/download/> or
GnuPG 2.2.24 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:
An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:
The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix.
New versions of the GnuPG VS-Desktop(tm) as well as Gpg4win for Windows
featuring this version of GnuPG will be released shortly.
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-2.2.24.tar.bz2 you would use this command:
gpg --verify gnupg-2.2.24.tar.bz2.sig gnupg-2.2.24.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-2.2.24.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
(traditional and simplified), Czech, French, German, Italian,
Japanese, Norwegian, Polish, Russian, and Ukrainian being almost
Documentation and Support
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 reference manual of the system.
Separate man pages are included as well but they miss some of the
details available only in thee manual. The manual is also available
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. https://wiki.gnupg.org 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 currently mostly financed by donations. Two full-time employed
developers as well as two contractor exclusively work on GnuPG and
closely related software like Libgcrypt, GPGME and Gpg4win.
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, or answering questions on the mailing
Many thanks to our numerous financial supporters, both corporate and
individuals. Without you it would not be possible to keep GnuPG in a
good and secure shape and to address all the small and larger requests
made by our users. Thanks.
