If you have a full header backup, then you can use that to restore the container header via `cryptsetup luksHeaderRestore`, or you can use a detached header via `cryptsetup --header`. If you have only the master key, then you can write a new header (possibly detached) with that specific master key using `cryptsetup luksFormat --master-key-file`. I recommend making a fresh header backup first in that case, in case you make a mistake. -- Michael Kjörling • https://michael.kjorling.se • michael@xxxxxxxxxxx “People who think they know everything really annoy those of us who know we don’t.” (Bjarne Stroustrup) _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
