Size : 5.5 Kb
Code : Win32ASM compiled with MASM32
Goal : Find the correct serial. 
Means: No patching or loaders allowed

Extra: File is not packed, no code had been hidden.
       Don't try to bruteforce all combinations, too much work!
       Instead try to figure out the 'holes' in the code.
       If you did that, you can start to brute the key :-) 
       Because of the 10 digit keylength, I give you the first 2 butttons :
       79xxxxxxxx

Story: You are standing in front of a large storageplace, no windows, only one 
       door. Inside the building there are some pre-production nanocomputer
       prototypes (the only ones existing).
       In your left hand, you have a disk with a 512 bits encrypted message you           
       intercepted. You HAVE TO decypher it today! Otherwise you will never know
       the exact plans of the terrorists, and we all know how that ends... 
       The computers inside the building are the only ones fast enough to brute
       force the message by tonight!
       So there you are, in front of that huge steel door, with only a keypad...


Greetz,
