Why? So you can enter it and be redirected to their company website?
THE RELIEF WILL BE AMAZING!
Do you promise.... I need to see that fucking company website so bad!!
And plz bitch, dickrolling a seasoned dick-roller. Wait that didn't cum out right.
Dude go back and read amaturesurgeons post. You know the one reffrencing the other post and I basically called you a dumbass, and reread it and follow the fucking directions. Do you see what I mean about you being a dumbfuck? There is zero reason for you to see that site you will never ever ever get hired by them.
Saw this on the news earlier, and did some searching for the answer, cause I was interested in how to do it:

Still on it. Exe requests license.txt, which needs to contain a decoded version of a hash. Some russian with rainbow tables bruteforced the hash to resolve to 'cyberwin', while we know that the file must have a header of 'gchq' (hardcoded in the exe, can find by decompiling easily).
The program then takes these values, and reads 12 more bytes from license.txt. It then makes a request to canyoucrackit.co.uk/hqDTK7b8K2rvw/0/0/0/key.txt
Now the /0/0/0/ are incorrect. They are the last 3 DWORDs read from license.txt, encoded via %X. So we're now trying to figure out what those 3 DWORDS are. In the previous problems, there were 3 DWORDS suspiciously left lying around doing nothing. I spent an hour inputting combinations of those, but to no avail.
I'm stuck now. Soon as I figure it out I suspect I'm at the end.
Damn, I got final exams this week

Just kept manually inputting combinations of the 3 DWORDs until it worked. Really fucking stupid end to what was otherwise a great challenge.
Cheers.
