LUKS (Linux Unified Key Setup) is a general-purpose encrypted disk format. It supports, for example, multiple keys, and the possibility of changing keys without re-encrypting the entire volume. Some Linux distributions support LUKS by default, using cryptsetup and related utilities, as if it were an advanced form of dm-crypt.

A LUKS volume begins with a header containing a variety of (unencrypted) information about the encrypted data.
