LUKS Integration
LUKS is used to encrypt a block device. The contents of the encrypted device are arbitrary, and therefore any filesystem can be encrypted, including swap partitions. The presence of this header is a major difference between LUKS and plain dm-crypt, since the header allows multiple different passphrases to be used, with the ability to change and remove them with ease. However, if the header is lost or corrupted, the device will no longer be decryptable.
