If you preload them, it's not a legit key generator as you don't need the program to do that.
If you implement your own algorithm, again you don't need that program to achieve that.

So it's not a legit key generator. It's just a fake key generator template right?

If a program uses an algorithm to generate working keys on its own, it is called a key generator.

Yeah but this one doesn't use an algorithm. It requires you to implement your own/ or an existing one..
