"Good gentlemen,

I created a small crackme to be entertained for a ratillo.

It is programmed in MASM32 and no tricks antidebugger.

The mission, as usual, is to create the keygen. As I think is very simple try it without a bruteforce program.

Greetings.

Without the permission of peter punk friend of (www.portalhacker.net) portalhacker forum i have posted this keygenme as i found it great in keygenning. I posted this here for educational purpose for those who want to learn.

A great thanks to friend PetePunk for his great keygenme.

hi

Here is the my Brute Force Program...(Optimized for 8 Thread Processor, Like Core i7)

well, im Noob on Keygenning...when i saw your Algorithm...(ReadByte from Key,OR lastStuff with this, then LastStuff*4 and...)

i felt its better to do just some Test by my hand...not writing some keygen or something similar...

CRC of Your User XOR Value(of Calced from Serial) should be Orginal Key that I Brute Forced....

so XOR Main Key with your own CRC, the Serial Value shoule be that....

so just play a bit with Serial to Reach your Serial.

Kind Regards

Thank you Raham. Could you please give an example?

I also made a bruteforcer...Its only running in only in 1 thread and not very optimised but it works smile.png

The source is included (Lazarus/FPC).

And i also made a small tutorial. Attached as PDF

Update :

I added a keygen to this post and an update on the tutorial. Its indeed possible to skip the bruteforce and calculate the serial immediate.
