Linux Unified Key Setup

"LUKS" redirects here. For the American painter, see George Luks.

In computing, the Linux Unified Key Setup or LUKS is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux.

While most disk encryption software implements different and incompatible, undocumented formats, LUKS specifies 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 with LibreCrypt (formerly DoxBox).

The design of LUKS aimed to conform to the TKS1 secure key setup scheme.[2]
