Notable features of the design include key-dependent S-boxes and a highly complex key schedule. bcrypt) used in OpenBSD uses an algorithm derived from Blowfish that makes use of the slow key schedule; the idea is that the extra computational effort required gives protection against dictionary attacks. The secret key is then, byte by byte, cycling the key if necessary, XORed with all the P-entries in order. Read the keyscheduling code @forest he's not talking about bcrypt, which would give different outputs, but the classic encryption algorithm.
