* AES Encryption/Decryption (CBC-Mode)

For AES there is the "SimpleAES" package[1] which is super easy to use:

import qualified Data.ByteString as BS import Data.ByteString.Lazy as BL

import Codec.Crypto.SimpleAES

key :: IO Key key = BS.readFile "key"

encrypt :: ByteString -> IO ByteString encrypt bs = do k <- key encryptMsg CBC k bs

decrypt :: ByteString -> IO ByteString decrypt bs = do k <- key return $ decryptMsg CBC k bs

(note that the key is a strict ByteString while the encrypted/decrypted data is lazy) [1]: http://hackage.haskell.org/package/SimpleAES
