CoD 2 Encryption

[stevomitric]

Hello again...
i'm having problems with decrypting cod2 data. Actually its not a problem. I simply don't know the encryption key.

Okey here is what i've done so far (Language: Python):

I got 2 Computers connected together on LAN.

On the first one i've written the server script ( how the original cod server would responde )
Code:

import socket #importing module

IP = "192.168.1.119" #my Local IP
PORT = 28960 #Port of server

sock = socket.socket(socket.AF_INET, # Internet
					socket.SOCK_DGRAM) # UDP
					
sock.bind((IP, PORT)) #Creating the server ( opening the IP and PORT)

while True:
	data, addr = sock.recvfrom(7000) #listening for data to come
	print "received message:", data, addr #printing what i got
	if 'connec' in data: # if i get connect request from a client send him following:
		sock.sendto('\xff\xff\xff\xffconnectResponse', addr)
	if 'chal' in data: # if i get challange request from client send him following:
		sock.sendto('\xff\xff\xff\xffchallengeResponse 1253163161', addr)

And on the 2. computer i just started CoD2 and connected to 192.168.1.119:28960 (server created)

i get the following:

Code:

ÿÿÿÿgetchallenge 0 "2d0ac480dfee724400cbf515d4003c45"
ÿÿÿÿconnect "\cl_anonymous\0\cl_punkbuster\1\cl_voice\1\cl_wwwDownload\1\rate\5000\snaps\20\name\stEvo\protocol\118\challenge\1253163161\qport\2096"
