ClassicHasClass hat es fertig gebracht, sich aus einem Commodore SX-64, einer tragbaren Version des C64, einen Zwei-Faktor-Authentifikator zu basteln. Mann muss halt immer das Ding mit sich rumschleppen, was den Vorteil hat, dass es wohl kaum einer klauen würde, um an deine Schlüssel zu kommen. Nerd-Gold.
Hier erklärt ClassicHasClass wie das funktioniert. Also falls irgendwer von euch einen SX-64 rumstehen hat.
The terminal window is showing a generated time-based one-time password for a full key, and the emulated 64 is showing the correct key, at the correct time, which was known and tested to be valid. Yes, you really can use your Commodore 64 for multi-factor authentication to generate TOTP codes!
Keys can be entered manually in hexadecimal or loaded as binary files from disk (you specify the file, offset and length), and it can either use the real-time clock in CMD FD and HD devices or with devices implementing a compatible T-RA command or you can just manually enter the time for demonstration.
