dm-crypt is a disk encryption system using the kernels crypto API framework and device mapper subsystem. With dm-crypt, administrators can encrypt entire disks, logical volumes, partitions, but also single files. The dm-crypt subsystem supports the Linux Unified Key Setup (LUKS) structure, which allows for multiple keys to access the encrypted data, as well as manipulate the keys (such as ... cryptsetup-reencrypt(8) - Linux manual page - Michael Kerrisk Cryptsetup-reencrypt can be used to change reencryption parameters which otherwise require full on-disk data change (re-encryption). You can regenerate volume key (the real key used in on-disk encryption unclocked by passphrase), cipher, cipher mode. Cryptsetup-reencrypt reencrypts data on LUKS device in-place. <![CDATA[Arch Linux Forums / Accident - ran e2fsck on ...

Unlocking a luks volume with a USB key – /dev/blog A luks encrypted disk partition is great. The only thing that can bug you from time to time is that you have to specify the key before you can use it. Or maybe, if you try to mount the volume with /etc/fstab, you’ll be prompted for the password during boot.. Wouldn’t it be great, if you could use a real key to unlock your encrypted volume? Not a keyfile, but a physically existent key like ... cryptsetup-reencrypt - tool for offline LUKS device re ...
