You have to find the key to solve the challenge.

The problem:
The .NET executable contains AES-encrypted text. It waits
for you to input the correct key to display the clear text.
The key is somewhere hidden in the attached files.

The rules:
- Finding the complete final key,
- Description of the solution
- No key-posting to the discussion board

If the sugggested difficulty (Level 2) seems too high or too low
just drop a notice, it will be adapted accordingly.

Have fun!

Nice work!! Thanks for solving!
I did not know the link you are pointing into your solution. And btw, there is also another, pure algorithmic possibility to solve!

09. Mar 2012		Hi Josh! Very nice crackme. The hardest part was to figuring out 'what' to do. I coded a small program to solve the crackme completely.

I also wrote about your the program -using your crackme as sample- in my blog: [SPOILER!]
