Hello everyone,


 


Here's my new KGM challenge for learners. As the name suggest this is a puzzle and I guess to solve this you must have some knowledge about something :P I will not reveal here what knowledge. Try yourself to find it ;)


One more thing, if you try to patch this KGM, you have to understand it else it will warn you :P


 


A valid submission is:


1. Only a keygen coded on your own.


 


Rules


1. No brute force, no code ripping or patching :P


 


If you have some time write a nice tutorial explaining the method and technique used inside.

@Kurapica: That's because I'm lazy by nature. ;)  


 


Now that I start to think more about this keygenme - there are "cleaner" ways to keygen it. But my way still works..

Yeah, it was a nice one. :)


 


BTW - small bug in a keygenme: if you enter correct key and press "Register", you'll get a good boy message. If you click "Register" one more time, you'll get bad boy message - that's incorrect.
