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 amongst different programs, but also assures that they all implement password management in a secure and documented manner.
