In my experience, whenever I think something would be cool, it's almost always the wrong thing to do. ;) > Or is there another form of > encryption I should look at? I don't think you really want "serious" encryption at all. Have a look here. http://www.searchlores.org/protec/protec.htm Then go have a crack at this. http://www.reverser-course.de/ After all, the best way to learn good security is to practice breaking into things... You could just crack into your own stuff, but most people who go in and crack their own stuff say "this is way too hard". Then you meet people who don't think twice about patching import tables and adding completely new code into the WndProc (which I'm doing to a program right now, as luck would have it), and the definition of "hard" starts to change. I really like this subject, so I could babble about it for days. Email me privately if you'd like to trade some ideas.
