WebJan 1, 2024 · Blowfish's flexible key length is arguably a disadvantage, since it's an invitation to use a passphrase or other non-random secret directly as a key. This is a bad idea: block cipher key setup is supposed to be as fast as possible, while passphrases should be run through a KDF that is as slow as possible. WebVersion 1.3 adds support for the $2b$ prefix introduced in OpenBSD 5.5+, which behaves exactly the same as crypt_blowfish's $2y$. This way, full compatibility with OpenBSD's bcrypt is achieved at this new prefix.
