Try `cryptsetup luksAddKey $device`. It asks you to enter the old key and then lets you install an additional one. You can later delete that second key. Please look at the man-page for the necessary command. BTW: Please don't top-post, e.g. put your response below the message you are quoting (where I've moved your reply). That facilitates reading long threads. Hope this helps, Florian Philipp
