NAME
       cryptsetup-ssh - manage LUKS2 SSH token

SYNOPSIS
       cryptsetup-ssh <options> <action> <action args>

DESCRIPTION
       Experimental  cryptsetup plugin for unlocking LUKS2 devices with token connected to an SSH
       server.

       This plugin currently allows only adding a token to  an  existing  key  slot,  see  crypt-
       setup(8) for instruction on how to remove, import or export the token.

   Add operation
       add <options> <device>

              Adds the SSH token to <device>.

              Specified  SSH  server  must  contain  a  key  file  on  the  specified path with a
              passphrase for an existing key slot on the device.  Provided  credentials  will  be
              used by cryptsetup to get the password when opening the device using the token.

              --ssh-server, --ssh-user, --ssh-keypath and --ssh-path are required for this opera-
              tion.

       --key-slot=NUM
              Keyslot to assign the token to. If not specified, the token will be assigned to the
              first key slot matching provided passphrase.

       --ssh-keypath=STRING
              Path to the SSH key for connecting to the remote server.

       --ssh-path=STRING
              Path to the key file on the remote server.

       --ssh-server=STRING
              IP address/URL of the remote server for this token.

       --ssh-user=STRING
              Username used for the remote server.

OPTIONS
       --debug
              Show debug messages

       --debug-json
              Show debug messages including JSON metadata

       -?, --help

       -V, --version

NOTES
       The  information  provided when adding the token (SSH server address, user and paths) will
       be stored in the LUKS2 header in plaintext.
