About Strongbox
Strongbox supports the well-known, portable and open Password Safe (version 3) and KeePass file formats (KeePass 1 and 2, i.e. KDB, KDBX (3.1 and 4)). Strongbox uses encryption algoritms likes TwoFish, Argon2d, ChaCha20, Aes, Salsa20 and various other cryptographic techniques (SHA256s, HMACs, CSPRNGs) to store groups and entries, containing various secrets, mostly designed around password storage. You can also store file attachments in KeePass format safes. YubiKey is also supported.
