| 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.<br> |
