        data : bytes to be encrypted
        pad  : Optional argument for decryption 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 decrypted
        with the already specified key. In PAD_NORMAL mode, if the
        optional padding character is supplied, then the un-encrypted
        data will have the padding characters removed from the end of
        the bytes. This pad removal only occurs on the last 8 bytes of
        the data (last data block). In PAD_PKCS5 mode, the special
        padding end markers will be removed from the data after
        decrypting, no pad character is required for PAD_PKCS5.
