Furthermore, you should forget about encrypting your program until you 
are sure that it is something that needs encrypting. In my experience, 
most times newbies start waffling on about encrypting their precious code 
(usually displaying total confusion about encryption technology), it 
turns out their critical application is something like Notepad only with 
fewer features.

Not that I'm jaded at all.
