current implementation uses AES encryption in CFB mode.

from Crypto.Cipher import AES
from Crypto import Random

def encrypt(aeskey, data):
""" encrypt string with given aes key """
iv = Random.new().read(AES.block_size)
cipher = AES.new(aeskey.decode("hex"), AES.MODE_CFB, iv)
encrypted_data = iv + cipher.encrypt(data)
return encrypted_data.encode("hex")

still needs some investigation if this is the way to go. but replacing the encrypt/decryption functions should be easy.
