OK, I assumed you were talking about a scenario like this:
player starts client
client connects to server
client retrieves key from server
client and server communicates using this encrypted key
With source, I use the code base of the client to construct a proxy;
player starts proxy
proxy connects to server
proxy retrieves key from server
proxy and server communicates using this encrypted key
player starts client
client connects to proxy
proxy pass "standard/phony" key to client (not really important)
proxy and client communicats using phony key.
The proxy - in this setup - is left to do what ever it wants with the

Yes, but if you have the code that can decrypt alread - and you will need

I know that - my assumption is that the client actually -decrypts- the
information, and that the player has access to the client code.
I have a feeling I am not understanding you here. Please explain.
