Hi Milan, if I decide to use luks1 format for my detached header, what size do I need to allocate for the header file ? >From the FAQ on gitlab, it would seem luks1 needs 2MB header file (Payload offset * 512), but when I use the "luksHeaderBackup" command on an existing standard luks1 partition: cryptsetup luksHeaderBackup /dev/sde1 --header-backup-file sde1.header it actually creates a file of size 1,052,672 bytes Is this the complete luks header ? If I want to minimize the size of LUKS header, without changing any default settings, can I use a 1,052,672 bytes file for my luks1 header? thank you, _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx https://www.saout.de/mailman/listinfo/dm-crypt
