Good afternoon guys!
Strictly do not scold me, I'm a beginner! I want to ask experienced programmers how to put protection on their product? Or what kind of technology is it?
It’s just that there are a lot of rumors - that programmers are being scammed, let’s say a programmer wrote a program, gave away a product - but didn’t receive money for it, but the program works for a couple of days and that’s it ..... Then the programmer called the program and receives his money and removes protection .. What is the name of this protection .. Again, do not judge strictly BEGINNER!

Simply read the installation date of the program. After 30 days, display a window asking you to register. Inside the code is requesting a computer name and issuing a hash.

If I were a programmer who is being called, I would also increase the price by 100% for such a scam))

There are many such defenses, from the not-so-efficient client sending a request to the server asking "Can I open the application?" to a regular blocker that requires a six hundred-digit password after a week of use, and never appears after entering it (+ fixing the application where it is not, in case the payment has already been received).
The second, in my opinion, is the most effective and universal.
