That could already be done... (-> changes nothing in this thread's context)

By the way, several months ago I read this thread again and decided that the advantages that would come from my program just aren't worth the risks (even with a sort of "protection" system). Therefore, no upload. I'm sorry for everyone that may have needed it.
Anyway, I'll upload some details about the algorithm as requested by Torkell, someday. Hopefully.

P.S.: Sorry for thread revival. His fault.
