The example I posted is what the game does by default. If you want to send packets manually you need to encrypt them the same way, as the server executable will try to decrypt it anyway (and if it's not encrypted, the data gets fucked up).

So what I'm saying is that you must always encrypt and decrypt packets prior to network transfer. (It can be removed from the executables of course, but why would you want to do something like that?)

OK!! Thank you somuch i understand this:

Example:

Client creates packet -> Client encrypts packet -> Clients sends packet
Server receives packet -> Server decrypts packet -> Server reads packet

can i put above code to antihack.dll too ? or have to make new dll and hook it to exe, or edit and put it into exe ?

can i put above code to antihack.dll too ? or have to make new dll and hook it to exe, or edit and put it into exe ?
Depends what you want to do.

If you want to create a sniffer, then an injected DLL with the encrypt and decrypt code is the way to go.

But if you want to send custom packets in your server, you can just use the functions in the executable and let it encrypt and decrypt data instead.

If you want to redirect the crypt procedures to a DLL it's possible too but kinda useless, I'd change them in the executable directly if needed.
