Linux Jargon Buster: What is LUKS Encryption
Linux Unified Key Setup - LUKS is a disk encryption specification created by Clemens Fruhwirth in 2004 and was originally intended for Linux. It is a well-known, secure, and high-performance disk encryption method based on an enhanced version of cryptsetup, using dm-crypt as the disk encryption backend. LUKS is also a popular encryption format in Network Attached Storage (NAS) devices.
LUKS can also be used to create and run encrypted containers. Encrypted containers feature the same level of protection as LUKS full-disk encryption. LUKS also offers multiple encryption algorithms, several modes of encryption, and several hash functions - a little over 40 possible combinations.
