Yeah.......I did use them, and it works perfectly. If you think for a second.........the purpose is to be able to log on to the computer in order to create new passwords, or in my case, install a different OS. All you are doing is uploading a text file with the system's existing encrypted passwords, to be decrypted. If you're stupid enough to keep those passwords after you're able to log in.....that's your problem. You're either too paranoid, or not literate enough to understand how it works.
