You cannot calculate the key from a cipher, even if you know the plaintext and encrypted data. Blowfish isn't better than MD5 or SHA512, as they serve different purposes. MD5 and SHA512 are hashing algorithms, Blowfish is an encryption algorithm.
WebThis answer is correct that Blowfish is an encryption algorithm, but in this context (eg, when used in bcrypt) it is used as a hashing algorithm by deriving a key from the source string … 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.

By default this initializes a Blowfish cipher that will interpret bytes using the big-endian byte order. Should the need arrise to use the little-endian byte order, provide "little" as the second argument.
