23 cfa37a7b 2004-04-10 devnull .PP
24 cfa37a7b 2004-04-10 devnull DES is being replaced by Rijndael, also known as AES, as the preferred
25 cfa37a7b 2004-04-10 devnull block ciper.
26 cfa37a7b 2004-04-10 devnull .IR setupAESstate ,
27 cfa37a7b 2004-04-10 devnull .IR aesCBCencrypt ,
28 cfa37a7b 2004-04-10 devnull and
29 cfa37a7b 2004-04-10 devnull .I aesCBCdecrypt
30 cfa37a7b 2004-04-10 devnull implement cipher block chaining encryption.
31 cfa37a7b 2004-04-10 devnull .I Keybytes
32 cfa37a7b 2004-04-10 devnull should be 16, 24, or 32.
33 cfa37a7b 2004-04-10 devnull The initialization vector
34 cfa37a7b 2004-04-10 devnull .I ivec
35 cfa37a7b 2004-04-10 devnull of
36 cfa37a7b 2004-04-10 devnull .I AESbsize
37 cfa37a7b 2004-04-10 devnull bytes should random enough to be unlikely to be reused but does not need to be
38 cfa37a7b 2004-04-10 devnull cryptographically strongly unpredictable.
