WebThe Blowfish encryption is a symmetric cipher and uses the same key for encryption and decryption. The Blowfish algorithm accepts keys from 4 bytes (32 bits) up to 56 bytes (448 bits). The methods provided by the library accept also a string password instead of a key, which is internally converted to a key with a chosen Hash function. Blowfish has a 64-bit block size and a variable key length from 32 bits up to 448 bits. It is a 16-round Feistel cipher and uses large key-dependent S-boxes. In structure it resembles CAST-128, which uses fixed S-boxes. The adjacent diagram shows Blowfish's encryption routine. Each line represents 32 bits.
