It doesn't work that way.  The information (code, and keys) needed
to decrypt the data are quite obviously somewhere accessible to the
user, be it in the game binary, installed data files, or data on the
CD.  The user might have to do some work to find the key/code, but
it's there. Otherwise, you're sending a bunch of data to a game
client that can't possibly use it.
