Is there anything wrong with this crackme?
Because its quite old... and imo not that hard.

There are not many Linux reversers.
"Allowed are only GPLed-tools" reduces that crowd even further.

Yeah, might be. But I want to learn from the solutions. And when they use e.g. IDA (sometimes even for windows), it helps nothing, beacause I dont want to buy such an expensive program for that.

Hi,
I think the problem with this crackme is that we don't know what to do and it is not really motivating :S. What are we looking for ? A basic "strings" doesn't give anything interesting (neither a "Good", nor a "Bad"), so we can easily conclude that once we will find a valid key, the crackme will not prompt anything ;).

Ever heard of hidden/encrypted/hardcoded strings? ;)
When you look a little bit in it and do something, you'll get messages. Btw printf is used.
Most code is for the messages, you don't need to care about that. The important code is quite short and easy. That's why I rated it "2".
