Introduction to YubiKeys (in openSUSE)
Everything you should know about YubiKey

presented by Karol Babioch

YubiKeys are handy little USB tokens that allow for hardware-based cryptography, which are becoming ever more prevalent. They provide support for a great variety of cryptographic protocols and standards, and offer several modes of operations. While this makes them very versatile, it can also be somewhat confusing, especially when you are only getting in touch with them for the first time.
