NAME

       clevis-luks-unlockers - Overview of clevis luks unlockers

OVERVIEW

       Clevis provides unlockers for LUKS volumes which can use LUKS policy:

       ·   clevis-luks-unlock - Unlocks manually using the command line.

       ·   dracut - Unlocks automatically during early boot.

       ·   systemd - Unlocks automatically during late boot.

       ·   udisks2 - Unlocks automatically in a GNOME desktop session.

       Once a LUKS volume is bound using clevis luks bind, it can be unlocked using any of the
       above unlockers without using a password.

MANUAL UNLOCKING

       You can unlock a LUKS volume manually using the following command:

           $ sudo clevis luks unlock -d /dev/sda

       For more information, see clevis-luks-unlock(1) <clevis-luks-unlock.1.adoc>.

EARLY BOOT UNLOCKING

       If Clevis integration does not already ship in your initramfs, you may need to rebuild
       your initramfs with this command:

           $ sudo dracut -f

       Once Clevis is integrated into your initramfs, a simple reboot should unlock your root
       volume. Note, however, that early boot integration only works for the root volume.
       Non-root volumes should use the late boot unlocker.

       Dracut will bring up your network using DHCP by default. If you need to specify additional
       network parameters, such as static IP configuration, please consult the dracut
       documentation.

LATE BOOT UNLOCKING

       You can enable late boot unlocking by executing the following command:

           $ sudo systemctl enable clevis-luks-askpass.path

       After a reboot, Clevis will attempt to unlock all _netdev devices listed in /etc/crypttab
       when systemd prompts for their passwords. This implies that systemd support for _netdev is
       required.

DESKTOP UNLOCKING

       When the udisks2 unlocker is installed, your GNOME desktop session should unlock LUKS
       removable devices configured with Clevis automatically. You may need to restart your
       desktop session after installation for the unlocker to be loaded.
