clevis luks pass -d DEV -s SLT

The clevis luks pass command extracts the passphrase used for binding a particular slot in a LUKS device. For example:

clevis luks pass -d /dev/sda1 -s 1

• -d DEV : The LUKS device on which to extract a passphrase from
• -s SLT : The slot to use for extracting the passphrase

clevis luks pass -d /dev/sda1 -s 1
<passphrase here>

Note that the output of clevis luks pass might be non-printable, in which case it would be better to redirect its output to a file and use it as a key file together with cryptsetup. For instance:

clevis luks pass -d /dev/sda1 -s 1 > slot1-passphrase

And the file slot1-passphrase will contain the passphrase associated with slot #1 in /dev/sda1.
