[KeygenMe] Puzzler by Blue

[Blue]

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 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

 

A valid submission is:

1. Only a keygen coded on your own.

 

Rules

1. No brute force, no code ripping or patching

 

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

Learners will have hard time with this.  Keygen + relevant C# src attached.

Nice kao

 

I love your permanent trademark

 

I'm just lazy.

@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..

Very nice bro, well done! May I ask you hows this keygenme challenge? I hope this time it might be a nice one

[kao]

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.
