- .SH DESCRIPTION
- .PP
- 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.
- .PP
- 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.
