Question

public class AESDecryption {

    protect         


        

Answer 1

The problem is that the server code uses a fixed IV (which is bad) with zeroes in it, but in your python code, you pass a new randomly generated IV to AES.new.

You can replace rndfile.read(BLOCK_SIZE) with "\x00"*BLOCK_SIZE.
