Operating Systems Linux Debian Problems with cryptsetup keyfile encrypted root partition under Debian 9, i386 Post 303024571 by tyuxar on Thursday 11th of October 2018 06:16:49 AM

The final goal is to put the key on USB, but right now i don't have any. This approach is solely exists for test and learning reasons. And since the USB key appears in the system as just another block device, like any partition, i'm trying to assemble the whole thing like this and then put the keyfile on USB.

I've searched through the net and i stucked. This is why i asked for help.

I've checked out luksAddKey. It's not what i want to achieve. It's for adding an additional keyfile, but i don't want to add an additional keyfile, i want to use that one on /dev/sda4.
