This crackme is really easy, i had written it for those who are making their first steps in the world of reversing. Those are the rules:

1. Please, try to find a valid serial instead of cracking it

2. There is a "bug" in this crackme that will prevent good-boy message in a certain condition. You must discover it and explain how it works.

3. OPTIONAL: write a keygen

I hope you will have fun!

Difficulty: 2 - Needs a little brain (or luck)

Found the valid serial for my name ;).
Pretty easy algorithm.
Also found the bug.
Weird place to have a bug there.
I think i know why it happens =).

Yeah, i think it was the easiest algorithm possible. As i said, it was just for starters, totally a no-match for seasoned reversers :-)

Hey I'm Nooby and have no clue how to disassemble this. Dot Net desnt work so I tryed Olly but I got no idea how to use it!!! AHHHH

@jvwarrior: yea, it isn't written in .NET, as you can see is in ASM. I suggest you to read some papers about Olly, using it isn't so difficult.
12. Apr 2008
I think using IDA and Olly together will be useful
