[Announce] GnuPG 2.5.19 released Werner Koch wk at gnupg.org Fri Apr 24 13:52:45 CEST 2026 Previous message (by thread): [Announce] [Security fixes] Libgcrypt 1.12.2, 1.11.3, 1.10.x released Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hello! We are pleased to announce the availability of a new GnuPG release: Version 2.5.19. This release adds a few new features and fixes a couple of bugs. The main features in the 2.5 series are improvements for 64 bit Windows and the introduction of Kyber (aka ML-KEM or FIPS-203) as 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. Note that the old 2.4 series reaches end-of-life in just two months. Thus update to 2.5.19 in time. As always with GnuPG new versions are fully compatible with previous versions. 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.

[T8171] Release-info: https://dev.gnupg.org/T7998 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 file 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-2.5.19.tar.bz2 (8127k) https://gnupg.org/ftp/gcrypt/gnupg/gnupg-2.5.19.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-w32-2.5.19_20260424.exe (5627k) https://gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.5.19_20260424.exe.sig The source used to build this installer for 64-bit Windows is available as https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.5.19_20260424.tar.xz (15M) https://gnupg.org/ftp/gcrypt/gnupg/gnupg-w32-2.5.19_20260424.tar.xz.sig This 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. Debian Packages =============== We also provide Debian style packages for a couple of Debian variants. See https://repos.gnupg.org/deb/gnupg/trixie/ or use the menu to switch to other distros/releases. If you encounter packaging problems please report them to the gnupg-devel mailing list. Due to the holidays it may take a few days until the packages are available. Windows Installer ================= A new Version of Gpg4win is in planning. For those who are affected by one of the now fixed bugs, it is possible to install the simple Windows installer mentioned above on top of gpg4win 5.0.1. 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-2.5.19.tar.bz2 you would use this command: gpg --verify gnupg-2.5.19.tar.bz2.sig gnupg-2.5.19.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-2.5.19.tar.bz2, you run the command like this: sha1sum gnupg-2.5.19.tar.bz2 and check that the output matches the next line: dbe9ce2aca9d553ed4367692575cee15204a95a6 gnupg-2.5.19.tar.bz2 e4de189d1310893b2f8e565781d25093944b883e gnupg-w32-2.5.19_20260424.tar.xz a2b9b2d0ad979209e1c74f28ff910ce6f97f0e41 gnupg-w32-2.5.19_20260424.exe Internationalization ==================== This version of GnuPG has support for 26 languages with Chinese, Czech, Dutch, French, Georgian, 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. If you are using cleartext signatures in your application please read https://gnupg.org/blog/20251226-cleartext-signatures.html and maybe https://gnupg.com/20260122-39C3_reply_gpg_fail.html In case of build problems specific to this release please first check https://dev.gnupg.org/T7998 for updated information.
