Cryptsetup Luksaddkey Slot - hinfante.com Luks critics of the slot mechanism (with whom I tend to agree) pointed out that if you revoke access (removing keys from slots) to a LUKS volume, still all copies of that volume around (backups) will be accessible by the keys. dm-crypt/Device encryption - ArchWiki - Arch Linux The most notable expansion was for the Linux Unified Key Setup (LUKS) extension, which stores all of the needed setup information for dm-crypt on the disk itself and abstracts partition and key management in an attempt to improve ease of use.

LUKS and Linux. Encrypting a storage device with LUKS. What is LUKS (Linux Unified Key Setup) ? Linux Unified Key Setup or LUKS is a disk-encryption specification created by Clemens Fruhwirth in 2004 and originally intended for the Linux operating system.

The system doesn't use LUKS, as it uses something else, so the LUKS problem can be system setup/settings related. The 'cryptsetup luksDump' doesn't show anything unusual either. Version, cipher name and mode, hash spec, etc. show normal values, and at least one key slot is enabled, so I don't think there is anything wrong with the drive.

If there is corruption in the LUKS header (more than just a single byte), it's pretty much impossible to recover. The LUKS header does not have a checksum for its key material, so - if it's damaged in any way, the cryptsetup luksDump will look same as always, but your passphrase simply won't work anymore. cryptsetup(8) - Linux manual page - Michael Kerrisk luksKillSlot

Dm-crypt - Gentoo Wiki 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.
