## DM_TARGET_CRYPT, TCPLAY - Transparent disk encryption
DragonFly has a device mapper target called dm_target_crypt (compatible with Linux' dm-crypt) that provides transparent disk encryption. It makes best use of available cryptographic hardware, as well as multi-processor software crypto.

DragonFly fully supports LUKS (cryptsetup) and TrueCrypt as disk encryption methods. tcplay, is a free (BSD-licensed) 100% compatible TrueCrypt implementation built on dm_target_crypt.
