ykpers (yubikey-personalization) is a library and command-line tool
to perform personalization of Yubico YubiKeys and is a reference
implementation for YubiKey configuration.
For challenge-response mode to work as a normal user, you will have
to create a 'yubikey' group and add your user to it. The recommended
GID is 288. You can create this by doing the following: groupadd -g
288 yubikey
You can use the plugdev group (or another group) if you like, by passing
a group name to the script:
GROUPNAME=plugdev ./ykpers.SlackBuild
