From wk at gnupg.org Tue Jan 14 10:54:55 2025 From: wk at gnupg.org (Werner Koch) Date: Tue, 14 Jan 2025 10:54:55 +0100 Subject: [Announce] GnuPG 2.5.3 released Message-ID: <87msftsosw.fsf@jacob.g10code.de> Hello! We are pleased to announce the availability of a new GnuPG release: version 2.5.3. This release is the fourth of a series of public testing releases eventually leading to a new stable version 2.6. We also release a second Beta version of the forthcoming Gpg4win 5.0. The main features in the 2.6 series are improvements for 64 bit Windows and the introduction of a PQC encryption algorithm. Other than PQC support the 2.6 series will not differ a lot from 2.4 because the majority of changes are internal to make use of newer features from the supporting libraries. 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 2.5.3 (2025-01-09) ================================================ [compared to version 2.5.2] * gpg: Allow for signature subpackets of up to 30000 octets. [rG36dbca3e69] * gpg: Silence expired trusted-key diagnostics in quiet mode. [T7351] * gpg: Allow smaller session keys with Kyber and enforce the use of AES-256 if useful. [T7472] * gpg: Fix regression in key generation from existing card key. [T7309,T7457] * gpg: Print a warning if the card backup key could not be written. [T2169] * The --supervised options of gpg-agent and dirmngr have been renamed to --deprecated-supervised as preparation for their removal. [rGa019a0fcd8] * There is no more default for a keyserver. Release-info: https://dev.gnupg.org/T7442 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 file server. The list of mirrors can be found at . 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-2.5.3.tar.bz2 (7989k) https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.5.3.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-w32-2.5.3_20250109.exe (5655k) https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.5.3_20250109.exe.sig The source used to build this installer for 64-bit Windows is available at https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.5.3_20250109.tar.xz (16M) https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.5.3_20250109.tar.xz.sig This Windows source tarball may also be used to download all required libraries at once to build a Unix version on any modern system. See the included README. For Windows a *Beta* version of Gpg4win, our full featured Gpg4win installer including this version of GnuPG as well as Kleopatra GUI and a PDF editor can be retrieved from here: https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta51/gpg4win-5.0.0-beta51.exe (43M) https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta51/gpg4win-5.0.0-beta51.exe.sig with the source code at: https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta51/gpg4win-5.0.0-beta51.tar.xz (279M) https://files.gpg4win.org/Beta/gpg4win-5.0.0-beta51/gpg4win-5.0.0-beta51.tar.xz.sig 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-2.5.3.tar.bz2 you would use this command: gpg --verify gnupg-2.5.3.tar.bz2.sig gnupg-2.5.3.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-2.5.3.tar.bz2, you run the command like this: sha1sum gnupg-2.5.3.tar.bz2 and check that the output matches the next line: 6dd8c940e1dff21d5e333a0ad3066e269e83df5e gnupg-2.5.3.tar.bz2 50f416d52eb423e5b359812ba02ceca2cea85c91 gnupg-w32-2.5.3_20250109.tar.xz acb39daee05aced0d37195f4ad739c16bda9aa5e gnupg-w32-2.5.3_20250109.exe 84a1169f55e3ddef02567fd0f3a0b666a9881107 gpg4win-5.0.0-beta51.exe 2fa55c64ed9238c7b745fa8d54978d4713a7e2b9 gpg4win-5.0.0-beta51.tar.xz Internationalization ==================== This version of GnuPG has support for 26 languages with Chinese (traditional and simplified), Czech, French, German, Italian, Japanese, Norwegian, Polish, Portuguese, 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/T7442 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 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, Kleopatra 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.
