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:

Quite easy to fish, but still a good crack me.
I haven't yet completely understood how the algorithm works but a tutorial is coming soon.

Cheers man! I would love to see the tutorial :D
Once it is up, I will let you know how the algorithm works, though it is kinda simple.

collecting the serial is pretty straight forward, but the algorithm seems complicated, lol.

Thanks for the crackme!

maybe the composing values is the important..
fish is good
cmp method with long for use nx , xn, ed , de

but the theme is how find all values posibles or understand at all the sumation..example user 1 , user 2, user 21 , user 12

values for user 12 = 1+2 and values from letters are from string..

tutorial cybercrisis is a fish way..

is posible post a tutorial for fish this app and solve this'?

Thank you for submitting a solution :)
I had no intentions of creating a new CrackMe before this one was solved, with a solution aswell.
When I get some spare time I will make a new one;)
