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)
