Blowfish is Bruce Schneier's symmetric block cipher. It supports variable length keys from 32 to 448 bits and has a block size of 64 bits. Both CBC and ECB modes are supported.

setupBFstate takes a BFstate structure, a key of at most 56 bytes, the length of the key in bytes, and an initialization vector of 8 bytes (set to all zeroes if argument is nil). The encryption and decryption functions take a BFstate structure, a data buffer, and a length, which must be a multiple of eight bytes as padding is currently unsupported.
