Encrypt and decrypt strings using Python pydes and Base64 modules

The code is as follows:

import pydesimport base64key =  "Gogenius" Iv =   "Gogen123" #  encryption Def encrypt_str (data):    #  encryption method      method = pydes.des (KEY, PYDES.CBC, IV, PAD=NONE, PADMODE=PYDES.PAD_PKCS5)     #  Execute plus password     k = method.encrypt (data)      #  go Base64 encode and return     return base64.b64encode (k) #  decryption def  DECRYPT_STR (data):     method = pydes.des (key, pydes.cbc, iv, pad= NONE, PADMODE=PYDES.PAD_PKCS5)     #  codec     k = for base64  base64.b64decode (data)     #  re-performs des decryption and returns     return  Method.decrypt (k) encrypt = encrypt_str ("1234567") print (Encrypt) decrypt = decrypt_str ( Encrypt) print (Decrypt)
