This is my first crackme, aswell as its my first c++ program.
The task is to reverse the algorithm, and create some serial keys. Patching is not allowed.
If you feel like making a tutorial, please put some effort in it, as I have used a good amount of time in making the crackme.

Here you have some examples:
