This is to announce libidn-1.44, 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.
There have been 38 commits by 1 people in the 64 weeks since 1.43. See the NEWS below for a brief summary. Thanks to everyone who has contributed!

Verify the base64 SHA3-256 checksum with 'cksum -a sha3 --check' from coreutils-9.8. 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-1.44.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 <[email protected]> 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 [email protected] 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-1.44.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 > libidn-sigsum-key.pub ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILzCFcHHrKzVSPDDarZPYqn89H5TPaxwcORgRg+4DagE EOF Run a command like this to verify downloaded artifacts: sigsum-verify -k libidn-sigsum-key.pub -P sigsum-generic-2025-1 \ libidn-1.44.tar.gz.proof < libidn-1.44.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://https.git.savannah.gnu.org/git/libidn.git with commit b42f1bad97bbe6a5493668ef8594719e5db96e36 tagged as v1.44.
