Two and a half months in development, KeePassXC 2.6.3 is here to introduce support for the Argon2id key derivation function (KDF), which is a hybrid version of Argon2 and Argon2i. A KDF is a cryptographic hash function designed to derive one or multiple secret keys from a secret value like a key, passphrase or password. According to the developers, Argon2id is less vulnerable to side-channel-attacks than Argon2d, and it’s also recommended by IETF. Additionally, this release adds support for XMLv2 key files, improves import and export of CSV files, and automatically hides the key file path and re-selects the previously selected entry when unlocking the password database.
