This was created in hopes to show new reversers (myself included) some examples of simple obfuscation, among other easy tricks, in a minimal amount of code to hash through.

Rules: No patching, find a valid serial. No brute force is required, no hard math, its simple.

The source code is included, and the password for the will be shown when you enter a valid serial.

I hope you enjoy.

Like you said: simple obfuscation, easy tricks :).
Nice crackme, uploaded tutorial.

Obfuscation? Where?!? XD
To solve this one you can skip the whole obfuscated code, just pay attention near the good messagebox and nothing more

OK, perhaps I should have said extremely simple obfuscation. :-) Was just an example of using junk bytes and an indirect jmp to trick the debugger. I think it can see odd to a new reverser -- I know it seemed odd to me!

We always wait a few days to allow more persons to submit their solutions so they are all approved at the same time.
It has never been a race either.

Niiice! I thought this one would be a piece of cake but took me a day to fully understand what your code makes :D I found it pretty awesome - although I'm a noob yet ;]
