The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and was originally intended for Linux.

While most disk encryption software implements different, incompatible, and undocumented formats[citation needed], LUKS implements a platform-independent standard on-disk format for use in various tools. This not only facilitates compatibility and interoperability among different programs, but also assures that they all implement password management in a secure and documented manner.[1]

The reference implementation for LUKS operates on Linux and is based on an enhanced version of cryptsetup, using dm-crypt as the disk encryption backend. Under Microsoft Windows, LUKS-encrypted disks can be used via the Windows Subsystem for Linux[2]. (Formerly, this was possible with LibreCrypt[3], which currently has fundamental security holes, and which succeeded FreeOTFE, formerly DoxBox.)

LUKS is designed to conform to the TKS1 secure key setup scheme.[4]
