    *ivec)

 DESCRIPTION     
 |  |  |  | DES is being replaced by Rijndael, also known as AES, as the preferred
    block ciper. setupAESstate, aesCBCencrypt, and aesCBCdecrypt implement
    cipher block chaining encryption. Keybytes should be 16, 24, or
    32. The initialization vector ivec of AESbsize bytes should random
    enough to be unlikely to be reused but does not need to be
    cryptographically strongly unpredictable.
