Packet Encryption/Decryption

[S7oneGhos7]

Hi All,

I have also been playing with packet encryption/decryption. I think the server creates a session key (used to encrypt network traffic between the client and the server) and sends it to the game client on startup. I have seen bots (in Lineage II) that capture the session key and encrypt/decrypt network traffic to spoof the server. I'm sure this is how ACXO works.

Does anyone know of a good packet capture program with encryption/decryption capability? I am looking at Wireshark and Capsa, but I am still a noob with these tools. What I want to do is: 1) capture packets during the login process, 2) find the session key (Blowfish I think), 3) decrypt the payload of the tcp/ip packets, modify the skill packets (as Black does with WPE Pro), 4) encrypt the packets, and 5) send the modified packets to the server.

Any ideas?

Thanks!

ya you need to get the session key then decrypt packets as they come in and then do whatever you want and encrypt.

if you have some progress on this pm me i would like to make a arhclord packet bot

Maybe we can have this as "project" to do together? talk at irc or somewhere and plan what to do? everyone has their own part, what they can do best, and they does it as it was planned in that way, it wouldnt take much time etc.. and lets us get to know each other better atleast, we all use or try to use bots
