This works:

def encrypt(self, value): value_s = six.iterbytes(value) repeated_iv = six.iterbytes(list(int(math.ceil(float(len(value)) / len(self.iv))) self.iv)) if len(self.password) == 0: xor2 = [a ^ b for a, b in zip(value_s, repeated_iv)] else: repeated_password = six.iterbytes(list(int(math.ceil(float(len(value)) / len(self.password))) self.password)) xor1 = [a ^ b for a, b in zip(value_s, repeated_iv)] xor2 = [a ^ b for a, b in zip(xor1, repeated_password)] return b''.join(map(six.int2byte, xor2))
