If anyone is interested in helping with C++ coding msg me ASAP.


My main goal is to learn how to encrypt packets, Right now people are useing WPE packet editors to cheat and even crash my game.

This is not a 'ask others to do things for you' forum.

Note: You can't stop someone with a packet editor and a determined mind.

Wouldn't encrypting packets stop them?

 

[Negata]

Well.. whatever's encrypted can be opened if you have what username1 called a determined mind. Encryption only makes things harder.

Just make your game discard invalid packets as a whole and add checks for acceptable value ranges to variables where one would want to send modified data, such as position and what not.

I wasn't the original coder.

Hi,
The easiest way:
1 - identify each packet with a sequential number, and check the order you process packets on the server. each packet out of oder will force a connection drop.
2 - XOR each packet with a fixed (64bit) key before you send it, and negotiate that key with the client when he first connects.

Other most stable way:
Find encryption libaries and use them on your app
