Hello! We are pleased to announce the availability of a new stable GnuPG release: version 2.4.1. This version fixes some minor regressions introduced with 2.4.0 and also adds a couple of new features. 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 2.4 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; the previous release was 2.3.8. - 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 2.4 has been back-ported to this series. 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. Please use 1.4 only for this purpose. Noteworthy changes in version 2.4.1 =================================== * If the ~/.gnupg directory does not exist, the keyboxd is now automagically enabled. [rGd9e7488b17] * gpg: New option --add-desig-revoker. [rG3d094e2bcf] * gpg: New option --assert-signer. [rGc9e95b8dee] * gpg: New command --quick-add-adsk and other ADSK features. [T6395, https://gnupg.org/blog/20230321-adsk.html] * gpg: New list-option "show-unusable-sigs". Also show "[self-signature]" instead of the user-id in key signature listings. [rG103acfe9ca] * gpg: For symmetric encryption the default S2K hash is now SHA256. [T6367] * gpg: Detect already compressed data also when using a pipe. Also detect JPEG and PNG file formats. [T6332] * gpg: New subcommand "openpgp" for --card-edit. [T6462] * gpgsm: Verification of detached signatures does now strip trailing zeroes from the input if --assume-binary is used. [rG2a13f7f9dc] * gpgsm: Non-armored detached signature are now created without using indefinite form length octets. This improves compatibility with some PDF signature verification software. [rG8996b0b655] * gpgtar: Emit progress status lines in create mode. [T6363] * dirmngr: The LDAP modifyTimestamp is now returned by some keyserver commands. [rG56d309133f] * ssh: Allow specification of the order keys are presented to ssh. See the man page entry for --enable-ssh-support. [T5996, T6212] * gpg: Make list-options "show-sig-subpackets" work again. Fixes regression in 2.4.0. [rG5a223303d7] * gpg: Fix the keytocard command for Yubikeys. [T6378] * gpg: Do not continue an export after a cancel for the primary key. [T6093] * gpg: Replace the --override-compliance-check hack by a real fix. [T5655] * gpgtar: Fix decryption with input taken from stdin. [T6355] Release-info: https://dev.gnupg.org/T6454 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-2.4.1.tar.bz2 (7169k) https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.4.1.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-w32-2.4.1_20230428.exe (5305k) https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.4.1_20230428.exe.sig The source used to build this Windows installer can be found in the same directory with a ".tar.xz" suffix. A new release of Gpg4win including this version of GnuPG will soon be announced. 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-2.4.1.tar.bz2 you would use this command: gpg --verify gnupg-2.4.1.tar.bz2.sig gnupg-2.4.1.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-2.4.1.tar.bz2, you run the command like this: sha1sum gnupg-2.4.1.tar.bz2 and check that the output matches the next line: d7d021101361a5e1166a6c0cc1731276e7134547 gnupg-2.4.1.tar.bz2 ddef13a3d099b72e4136d76918e9e11a27e58472 gnupg-w32-2.4.1_20230428.tar.xz 4fcd84cb78c84970bc874c123d223f6521c1e566 gnupg-w32-2.4.1_20230428.exe Internationalization ==================== 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 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/T6454 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. Job Opportunity =============== We are looking for an experienced technical person for the g10 Code office in Erkrath. Your duties would be help with system administration and to extend our technical support team. Although we are running completely on free software, most of our customers are running Windows; thus experience with Windows management will be of advantage as well as a reasonable proficiency in German. If you are interested in a full time employment please contact us my mail. Thanks ====== Since 2001 maintenance and development of GnuPG is done by g10 Code GmbH and has mostly been financed by donations. Several full-time employed developers and contractors are working exclusively on GnuPG and closely related software like Libgcrypt, GPGME and Gpg4win. Fortunately, and this is still not common with free software, we have 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 trademarks GnuPG Desktop® or GnuPG VS-Desktop®. 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 helped with donations. *Thank you all* Your GnuPG hackers p.s. This is an announcement only mailing list. Please send replies only to the gnupg-users at gnupg.org mailing list.
