I'm stuck on this application and it's driving me crazy! I don't know how to write a brute forcer and I don't know where to start looking for the answer.

I tried directing the program to display the congratulations message, but it's all encrypted. I have no idea what to do with this...any help would be appreciated.

You won't solve this using that message, no. My best advice is following what happens to your input after you put it in. Apart from that, this thread has quite a bit of information on what to do. This one took longer to figure out than the other 6 combined for me, but it was worth it. Keep at it.

In regards to the bruteforcer, why not use the program logic to do it for you? If that doesn't work for you, read some more.
