Sheepings, everything you say is very reasonable. I agree with most of the statements. Thanks for the help!

You need to think about How the user can use the key on different computers. For example: if user has 2 or more computers.
How the user can use the key to the program if he changed the computer or laptop.
These little things should be well thought out.

This is an addition to my topic)

Also,
You can use a simple encryption function based on the user data for creating license keys. Or to generate keys at the server and verify them in the client side.

Beware of spending so much time that you end up with a secure product that no one wants to steal, because you never got around to implementing all the features and fixing all the bugs.

Ultimately, you need to make the process as painless as possible for people who were going to pay for the game anyway. Putting people off who were going to pay is far worse than preventing people who were never going to pay.

Because no matter how high you raise the bar, someone will hack it "just because they can". This group of people were never going to be customers no matter what you do. Better to regard them as "free advertising advocates" rather than "enemies". But that boils down to my first point, having a good product for them to talk about, not about how good/bad your security was.

Of the "free" games I've played in Google play store, all have had "in app purchases" as a means of trading "money" for "quicker progress through the game".

I agree with every word, Salem_c. I'm not going to do something incredibly secure. I just want to know how to license my product. How to do it in the best way. So that it is convenient to support, maybe, use the idea for possible other applications.
