30 cfa37a7b 2004-04-10 devnull .PP
31 cfa37a7b 2004-04-10 devnull Blowfish is Bruce Schneier's symmetric block cipher.  It supports
32 cfa37a7b 2004-04-10 devnull variable length keys from 32 to 448 bits and has a block size of 64
33 cfa37a7b 2004-04-10 devnull bits.  Both CBC and ECB modes are supported.
34 cfa37a7b 2004-04-10 devnull .PP
35 cfa37a7b 2004-04-10 devnull setupBFstate takes a BFstate structure, a key of at most 56 bytes, the
36 cfa37a7b 2004-04-10 devnull length of the key in bytes, and an initialization vector of 8 bytes
37 cfa37a7b 2004-04-10 devnull (set to all zeroes if argument is nil).  The encryption and decryption
38 cfa37a7b 2004-04-10 devnull functions take a BFstate structure, a data buffer, and a length, which
39 cfa37a7b 2004-04-10 devnull must be a multiple of eight bytes as padding is currently unsupported.
