That would be the master key that "vanished" with the header, right? That way I am out of luck as it seems. I did not manually make a backup of the LUKS header and I don't have a "dd" of that partition lying around (I do have a backup of the data though). - What are my chances of finding header information on the disk with hexdump? - Is there a documented way of backing up the LUKS header?
