I am trying to reverse engineer a license key for some software, the company that made it went out of business. In doing so, if you didn't already have the key their $50,000 machines become paperweights.
The key to unlock their driver takes information and exports it, then you send it to the company which they send back a different
.xuk file which you import and it unlocks the driver.
I have both the before and after
.xuk files and can open them in a hex editor, but I don't know how to read it.
