On Linux, encryption can be layered on top of a file system
using a <quote>loopback device</quote>. This allows an entire
file system partition to be encrypted on disk, and decrypted by the
operating system. On FreeBSD, the equivalent facility is called
GEOM Based Disk Encryption (<acronym>gbde</acronym>), and many
other operating systems support this functionality, including Windows.
Storage encryption can be performed at the file system level or the
block level. Linux file system encryption options include eCryptfs
and EncFS, while FreeBSD uses PEFS. Block level or full disk
encryption options include dm-crypt + LUKS on Linux and GEOM
modules geli and gbde on FreeBSD. Many other operating systems
support this functionality, including Windows.
