This is a command line client to manage the privacyIDEA server.
You can use it to fill an LUKS keyslot with the response of a challenge response Yubikey, that is managed with privacyIDEA.
.note:: You will also need the package at https://github.com/cornelinux/yubikey-luks to enable grub to read challenges from the yubikey.
You can also use it to manage SSH keys centrally for all your servers running openssh.
