        data : bytes to be encrypted
        pad  : Optional argument for encryption padding. Must only be one byte
        padmode : Optional argument for overriding the padding mode.

        The data must be a multiple of 8 bytes and will be encrypted
        with the already specified key. Data does not have to be a
        multiple of 8 bytes if the padding character is supplied, or
        the padmode is set to PAD_PKCS5, as bytes will then added to
        ensure the be padded data is a multiple of 8 bytes.
