Usage

1. DES

Define a DES object while passing in your key. Key should be a hex string representing an 8 byte hexadecimal number.

import des_Py
des = des_Py.DES("0x133457799bbcdff1")

You can encrypt by calling encrypt() and passing in a hex string representing an 8 byte hexadecimal number

des.encrypt("0x0123456789abcdef")    # -> "0x85e813540f0ab405"

You can simarly decrypt by calling decrypt() and passing in a hex string to decrypt

des.decrypt("0x85e813540f0ab405")    # -> "0x0123456789abcdef"
