Linux Unified Key Setup
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.
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 FreeOTFE.
On September 2013, Phoronix published a benchmark comparing performance between LUKS and eCryptfs. They used Ubuntu 13.10 (latest available at that time) and they obtained better results encrypting the whole disk using LUKS than encrypting just the user home using eCryptfs.
