nixCraft Posted March 3, 2021 Share Posted March 3, 2021 We can easily add a key file to LUKS disk encryption on Linux when running the cryptsetup command. A key file is used as the passphrase to unlock an encrypted volume. The passphrase allows Linux users to open encrypted disks utilizing a keyboard or over an ssh-based session. There are different types of key files we can add and enable LUKS disk encryption on Linux as per our needs: Passphrase keyfile - It is a key file holding a simple passphrase. Random text keyfile - This is a key file comprising a block of random characters which is much more resistant to dictionary attacks than a simple passphrase-based key file. Binary keyfile - We can defile an image, video, or any other static binary file as key file for LUKS. It makes it harder to identify as a key file. It would look like a regular image file or video clip to the attacker instead of a random text keyfile. Let us see how to enable LUKS disk encryption with a key file.
