Cryptsetup device in use

WebThe device-mapper crypt target (dm-crypt) provides transparent encryption of block devices using the kernel crypto API. In Red Hat Enterprise Linux, userspace interaction with dm-crypt is managed by a tool called cryptsetup, which uses the device-mapper infrastructure to setup and operate on encrypted block devices. Webcryptsetup [] DESCRIPTION cryptsetup is used to conveniently setup dm-crypt managed device-mapper mappings. These include plain dm-crypt volumes and LUKS volumes. The difference is that LUKS uses a metadata header and can hence offer more features than plain dm-crypt.
