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.
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 2048 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...
