The serial-generation code in this crackme is obfuscated, there are no signatures this time and the entire serial generation code has been re-written. After the unlock code has been found, type it in and it will de-obfuscate the serial generation code. If you enter an invalid code, the crackme will die (depending on your luck of course), as the de-obfuscation routine may very well result in invalid instruction sequences. After this bit has been complete it should be straight forward.

- No patching
- Find the correct unlock code
- Write a keygen
- Write a tutorial explaining how you solved this one and please include your code

I don't know how difficult this crackme is, so I would really appreciate your feedback on this, as I would like to put a difficulty level on the final release. Maybe can change it accordingly.

If you have any questions, please feel free to ask :o)

Well, I would say it's NOT OK - the purpose of this site is to learn, not to brag...

I know the purpose of this site is to learn, and posting a serial does'nt kill the joy, because its not a complete solution. All I wanted to ask was that whether these serial's for my name were working or not?, because there were quick-grabbed values. If asking for a validation is called "bragging" in your tounge, I really fear your ill-logic! And next-time plz mind your tounge!
