- There's really no foolproof way to encode a serial number into an executable,
- I think. Both of the above suggestions just make the job of the hacker
- harder, is all. If they can't do it scientifically, I'm sure they'll just start
- zapping at random until they hit the sweet spot.
-
- The primary point of my suggestion is to make it hard to hack. There is really
- no foolproof way around it.
-
- I kinda like your idea, though. Perhaps adding that in with randomized
- encryption, and a few other knicknacks... and the serial number part might be
- bigger than the main program. Owtch. It's a shame that a programmer would
- have to spend so much time protecting his work, instead of using it productively
- in development. :-(
