You are given a keygen.
There are 2 modes.
The first one is the easiest as someone with a little computer knowledge should easily figure it out.
The second one is a little trickier. But the alghorithm is fairly easy if you can find it.
The purpose is that you make the opposite of this. So I put in the generated key from the original file and your program returns the string.
For example.
GordonBM gives (hardcore mode):
9247109931023928283286380308924708453882326686447837
Engineer it so that when I put in
9247109931023928283286380308924708453882326686447837, its gives me GordonBM
However, the key you get is different every time.
Difficulty: 1 - Very easy, for newbies

Easy mode is easy, but hardcore mode is not unique, for example 'A' and 'S' both give 83. |
