Packet-encrypt/decrypt function

Hey guys

I'd have a biiig question:

Could anyone send me the packet encryption algorythm? I'm not so good in reverse engineering. I managed to inject my dll and see the packets unencrypted, but I'm simply not able to understand the algorythm.
Could you send me... a short description, C++, VB code, or any hint, how to learn it by myself?

Thank you, Regards
