Hello!
We are pleased to announce the availability of a new GnuPG release:
version 2.3.3. This is the fourth release in the new 2.3 series which
fixes a couple of bugs we introduced in 2.3.2 as well as a fix for
keyservers. 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.
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.
See https://gnupg.org/download/index.html#end-of-life
- Version 1.4 is only maintained to allow decryption of very old data
which is, for security reasons, not anymore possible with other GnuPG
versions.
Noteworthy changes in version 2.3.3 (2021-10-12)
===============================================
* agent: Fix segv in GET_PASSPHRASE (regression). [#5577]
* dirmngr: Fix Let's Encrypt certificate chain validation. [#5639]
* gpg: Change default and maximum AEAD chunk size to 4 MiB.
[ad3dabc9fb]
* gpg: Print a warning when importing a bad cv25519 secret key.
[#5464]
* gpg: Fix --list-packets for undecryptable AEAD packets. [#5584]
* gpg: Verify backsigs for v5 keys correctly. [#5628]
* keyboxd: Fix checksum computation for no UBID entry on disk.
[#5573]
* keyboxd: Fix "invalid object" error with cv448 keys. [#5609]
* dirmngr: New option --ignore-cert. [4b3e9a44b5]
* agent: Fix calibrate_get_time use of clock_gettime. [#5623]

(Put "use-keyboxd" into common.conf to use a fast SQLite
database instead of the pubring.kbx file.)

Getting the Software
====================
Please follow the instructions found at <https://gnupg.org/download/> 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
<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:
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.3.3.tar.bz2 (7412k)
https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.3.3.tar.bz2.sig
An installer for Windows without any graphical frontend except for a
very minimal Pinentry tool is available here:
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.3.3_20211012.exe (4701k)
https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.3.3_20211012.exe.sig
The source used to build the Windows installer can be found in the same
directory with a ".tar.xz" suffix.
If you want to use this GnuPG versions with Gpg4win simply install it on
on top of Gpg4win 3.1.16.
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-2.3.3.tar.bz2 you would use this command:
gpg --verify gnupg-2.3.3.tar.bz2.sig gnupg-2.3.3.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-2.3.3.tar.bz2, you run the command like this:
sha1sum gnupg-2.3.3.tar.bz2
and check that the output matches the next line:
b19a407076424704f1b00e8265254de1b3061659 gnupg-2.3.3.tar.bz2
bfb4e9fe2a69c763f15f6a7dd980c7ef6807277f gnupg-w32-2.3.3_20211012.tar.xz
f95dec36a3905c1a928e7b8b83d4eee8a8200364 gnupg-w32-2.3.3_20211012.exe
Internationalization
====================
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
completely translated.
Documentation and Support
=========================
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 the manual. The manual is also available
online at
https://gnupg.org/documentation/manuals/gnupg/
or can be downloaded as PDF at
https://gnupg.org/documentation/manuals/gnupg.pdf
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.
In case of build problems specific to this release please first check
https://dev.gnupg.org/T5565 for updated information.
Please consult the archive of the gnupg-users mailing list before
reporting a bug: https://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 https://bugs.gnupg.org. If you need commercial
support go to https://gnupg.com or https://gnupg.org/service.html.
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
discussion.
Thanks
======
Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH
and still mostly 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.
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
lists.
The financial support of the governmental CERT of Luxembourg
(GOVCERT.LU) allowed us to develop new and improved features for
smartcards (Yubikey, PIV and Scute) as well as various usability
features. Thanks.
Many thanks also to all other 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.
Happy hacking,
Your GnuPG hackers
