Linux Unified Key Setup (or LUKS for short), is a disk encryption specification widely used in Linux systems.
Created by Clemens Fruhwirth in 2004, it’s designed to provide a standardized encryption mechanism that’s both secure and user-friendly.
It protects data by encrypting it inside physical and logical disk partitions so that only authorized users can access the content of that encrypted partition.
