-- | Fast AES encryption/decryption for bytestrings
--   
--   A simplified binding to Brian Gladman's AES implementation, including
--   a copy of that implementation
@package SimpleAES
@version 0.4

-- | Encryption/decryption for lazy bytestrings. The input string is
--   zero-padded to a multiple of 16. It is your obligation to separate
--   encode the length of the string.
--   
--   Properties: x == y => crypt mode key iv dir x == crypt mode key iv
--   dir y take (length x) (crypt mode key iv Decrypt (crypt mode key iv
--   Encrypt x)) == x
crypt :: Mode -> Key -> IV -> Direction -> ByteString -> ByteString

-- | Encrypt a bytestring using a random seed (IV). Since the seed is
--   random, this function is tainted by IO.
encryptMsg :: Mode -> Key -> ByteString -> IO ByteString

-- | Encrypt a ByteString using a given seed (IV). The resulting ByteString
--   contains both the seed and the original length of the input (before
--   padding).
