SYNOPSIS
#include <u.h>
#include <libc.h>
#include <mp.h>
#include <libsec.h>
void setupBFstate(BFstate *s, uchar key[], int keybytes,
uchar *ivec)
void bfCBCencrypt(uchar *data, int len, BFstate *s)
void bfCBCdecrypt(uchar *data, int len, BFstate *s)
void bfECBencrypt(uchar *data, int len, BFstate *s)
void bfECBdecrypt(uchar *data, int len, BFstate *s)
DESCRIPTION
Blowfish is Bruce Schneier's symmetric block cipher. It supports vari‐
able 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.
