| 30 | .PP |
| 31 | Blowfish is Bruce Schneier's symmetric block cipher. It supports |
| 32 | variable length keys from 32 to 448 bits and has a block size of 64 |
| 33 | bits. Both CBC and ECB modes are supported. |
| 34 | .PP |
| 35 | setupBFstate takes a BFstate structure, a key of at most 56 bytes, the |
| 36 | length of the key in bytes, and an initialization vector of 8 bytes |
| 37 | (set to all zeroes if argument is nil). The encryption and decryption |
| 38 | functions take a BFstate structure, a data buffer, and a length, which |
| 39 | must be a multiple of eight bytes as padding is currently unsupported. |
