Blowfish is Bruce Schneier's symmetric block cipher. It supports vari‐
able 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.
