| 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. |
