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.

[edit] Identification
A LUKS (v1, at least) volume begins with signature bytes 'L' 'U' 'K' 'S' 0xBA 0xBE.
For version 1 this is followed by byte sequence 00 01
and for version 2 this is followed by byte sequence 00 02.
