Codec/Encryption.chs:52:57:
    Ambiguous type variable `e' in the constraint:
      (GHC.Exception.Exception e) arising from a use of `catch'
    Probable fix: add a type signature that fixes these type variable(s)
    In the first argument of `unsafePerformIO', namely
      `((do { ciph <- cipherOpen ct cm [];
              setKey ciph ck;
              setIV ciph ci;
                cipherDecrypt ciph str >>= return . Just })
      `catch`
        (\ _ -> return Nothing))'
    In the expression:
      unsafePerformIO
        ((do { ciph <- cipherOpen ct cm [];
               setKey ciph ck;
               setIV ciph ci;
                 cipherDecrypt ciph str >>= return . Just })
       `catch`
         (\ _ -> return Nothing))
    In an equation for `decrypt':
        decrypt ct cm ck ci str
          = unsafePerformIO
              ((do { ciph <- cipherOpen ct cm [];
                     setKey ciph ck;
                     setIV ciph ci;
                       cipherDecrypt ciph str >>= return . Just })
             `catch`
               (\ _ -> return Nothing))
