This is to announce libidn-1.43, a stable release. GNU Libidn is a fully documented implementation of the Stringprep, Punycode and IDNA2003 specifications. Libidn's purpose is to encode and decode internationalized domain name strings. There are native C, C# and Java libraries. Be aware that IDNA2003 and libidn are primarily for historic or compatibility use, and libidn2 is the successor with IDNA2008 and Unicode TR46 implementation and also provides a compatibility layer for GNU libidn.

Use a .sig file to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify libidn-1.43.tar.gz.sig The signature should match the fingerprint of the following key: pub ed25519 2019-03-20 [SC] B1D2 BD13 75BE CB78 4CF4 F8C4 D73C F638 C53C 06BE uid Simon Josefsson <si...@josefsson.org> If that command fails because you don't have the required public key, or that public key has expired, try the following commands to retrieve or refresh it, and then rerun the 'gpg --verify' command. gpg --locate-external-key si...@josefsson.org gpg --recv-keys 51722B08FE4745A2 wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=libidn&download=1' | gpg --import - As a last resort to find the key, you can try the official GNU keyring: wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg gpg --keyring gnu-keyring.gpg --verify libidn-1.43.tar.gz.sig Use the .proof files to verify the Sigsum proof. These files are like signatures but with extra transparency: you can cryptographically verify that every signature is logged in a public append-only log, so you can say with confidence what signatures exists. This makes hidden releases no longer deniable for the same public key. Releases are Sigsum-signed with the following public key: cat <<EOF > jas-sigsum-key.pub ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILzCFcHHrKzVSPDDarZPYqn89H5TPaxwcORgRg+4DagE EOF Run a command like this to verify downloaded artifacts: wget -q -Otrust.txt https://gnu.org/s/libidn/sigsum-policy-20250309.txt sigsum-verify -k jas-sigsum-key.pub -p trust.txt \ libidn-1.43.tar.gz.proof < libidn-1.43.tar.gz You may learn more about Sigsum concepts and find instructions how to download the tools here: https://www.sigsum.org/getting-started/ This release is based on the libidn git repository, available as git clone https://git.savannah.gnu.org/git/libidn.git with commit e0e97997e1424cf2070c1cee01c66bee65d17b60 tagged as v1.43.

Builds on the following pairs of systems are tested continuously in GitLab CI/CD to assert that the tarball is identical: Trisquel 11 against Ubuntu 22.04, PureOS 10 against Debian 11, Devuan 5 against Debian 12, AlmaLinux 8 against RockyLinux 8, and AlmaLinux 9 against RockyLinux 9. There are still minor variations between non-similar platforms, depending on the different versions of the bootstrapping tools used. For example, a tarball generated on a Trisquel 11 (derived from Ubuntu 22.04) system should be identical to a tarball from a Ubuntu 22.04 system, but will not be identical to a tarball generated on a PureOS 10 system which uses different bootstrapping tool versions. The release archive itself was prepared using Guix. ** We publish a minimal source-only tarball generated by 'git archive'. This tarball only contains the files stored in version controlled sources, and no auxiliary files. The source-only tarball may be reproduced with Git 2.48.1 from Guix. If something results in the 'git archive' format changing again, the tarball can only be reproduced using an earlier system. The git version in AlmaLinux 8, AlmaLinux 9, RockyLinux 8, RockyLinux 9, Devuan 5, Debian 12 and Ubuntu 24.04 all produce the same identical 'git archive' tarball. The git version used on Debian 11, PureOS 10, Trisquel 11 and Ubuntu 22.04 produce another identical tarball. These two 'git archive' outputs are not the same, due to how Git works. ** A use of uninitialized value bug was fixed in idna_to_unicode_4z4z. If the call to idna_to_unicode_44i failed due to an out of memory condition (malloc() returning NULL) then the code would copy the content of allocated but uninitialized memory into the output buffer. The bug was found using GCC's static analyzer. ** The C# Libidn.dll can now be built with .NET as well as Mono/SSCLI. ** Fix self-check tst-version due to broken strverscmp on Windows/musl. ** The release tarball uses tar --format=ustar. ** The idn tool now binds the "gnulib" domain for translations. ** Unicode tables are now rebuilt from source again. The lib/gen-unicode-tables.pl script stopped working with Perl 5.10 and in 2008 we added the then-generated source code files to git. Now we fixed the script to work with modern perl, so that gunibreak.h gunicomp.h gunidecomp.h can now be generated from source again. ** Update gnulib files and build fixes.
