fixed grammar, made the question a little more apparent, but the question itself still needs work. I still don't know what is being asked.

I am trying to find an encryption algorithm for a game client, andbut I need to find the actual register/stack in the client before I can decrypt/encrypt the packets correctly (on my emulated server side) but. The problem is that I have no idea how to find the function :S. How can

In OllyDbg, is there a way I can trace during my debugging, in order to find the function right after user input (in? The user input is a string converted to a char array, which is then encrypted in the executable. In this case, it would mean sending a packet to the game client, forand then it has to be decrypted in the game client) decrypts the packet.
