That's a really good idea. I have a couple more questions, if you don't
mind: I am going to distribute an app using py2exe. Is it reasonably
easy to apply this technique to bytecode stored inside the library.zip
file, or should I just include the encrypted Python files as separate
files?
Second, I hear that in general it is very difficult to make a
time-limited demo, because the code has to be all there, so all a
cracker has to do is bypass the "if". It seems that even this method
won't work for that. Do you know of any way to make time limiting
secure?
Thanks.
