The key to the application?

Let's say I have some application that I sell. How to organize the test key without server? That is offline?

To stuff on different places and obfuscated code to check the validity of the key, and then (if necessary) still nafig broken.

The best defense is a removal of commercially significant functionality to an external server.
To this response I will add that if the program is "mass", then your key is just hacked sooner or later (if, of course, do we need anyone). If it is sharpened by two dozen firms specialized in defense, maybe, makes no sense at all. (although, given that you are the student and a loner, then it is unlikely your case). - ellen_Watsi commented on July 12th 19 at 16:58
