Why? What? Are these legal? Do I care? I don't know.

There HASHES dude... By definition that means irreversible.

You could brute force them of course, but you've gotta have an algorithm... do you have one. It's probably different for each key.

Now, that's not to say you can't 'pass the hash.' I don't even know what software is on those CD's, and I'm pretty sure each piece of software on those CD's will handle the key/hash differently. More info may help. But if the info leads to illegal crud, it probably won't.
