Title: [QUESTION] LF Launcer to encrypt mpqs
Post by: Serifaz on August 19, 2011, 12:43:08 am

Hey guys, I'm looking for a launcher that will auto encrypt files before people can download them,
so they can not be tampered with, is this possible or no?
also if anyone knows of one that is open source or a way I can make it please let me know ;)

The MPQs need to be in their original form as soon as WoW wants to load them, else it wont work. Therefore you need to decrypt them before starting the game, leaving them available for being opened. If you're much into magic, you could inject into WoW and decrypt stuff in RAM. That will be a pain in the ass to write though.

tl;dr: Its not worth it.

A schlumpf said, encrypting would not be an option.

Your best bet is to distribute your patch via a custom launcher, and let WoW only open if the MD5 of the patches match. You will have to find a way to deny people from playing without your launcher. (maybe change clientbuild)
