dm-crypt is a transparent disk encryption subsystem in the Linux kernel that provides a generic way to create virtual layers of block devices that can do different things on top of real block devices like striping, concatenation, mirroring, snapshotting, and more.
Features include:
- Support advanced modes of operation, such as XTS, LRW and ESSIV (see disk encryption theory), in order to avoid watermarking attacks.
- Encrypt whole disks (including removable media), partitions, software RAID volumes, logical volumes, as well as files.
- Provides transparent encryption of block devices using the new Linux 2.6 cryptoapi.
- Offers similar functionality to cryptoloop but with clear code and a more flexible configuration.
- Highly flexible.
- Can be used for encrypting any disk-backed file systems supported by the operating system, as well as swap space.
- Encrypt RAID volumes and LVM physical volumes.
- Configured to provide pre-boot authentication through an initrd.
