Salutations.
Thank you all so much for the time and effort you put into your amazing project!
I've used it successfully many times!
I have a usage question for you if you'll allow me.
I am attempting to create a detached header in conjunction with a 1G offset.
The version of cryptsetup I am using is version 2.2.2.
My kernel is 5.4.3
What I expected:
> detached header file "detached_header.img" on /dev/sda1 (mounted at /mnt)
> luks protected data on /dev/sda1
The command I used.
> $cryptsetup luksFormat /dev/sd2 --offset 2097152 --header /mnt/detached_header.img
According to the man page, the --header option will override the positional <device> parameter.
Thus, when I run the above command (or variations of same) the device on which the "detached_header.img" file sits, becomes the target of the luksFormat.
What happened:
> /dev/sda1 becomes target of luksFormat. Fails with the following output;
$ Device wipe error, offset 93323264.
$ Cannot wipe header on device mnt/detached_header.img
No change on /dev/sda2
I know I'm misunderstanding something, but I can't figure out what it is.
Thank you ahead of time for any help you can provide!
-Omar
