1822- GEOM Based Disk Encryption (<acronym> gbde</acronym>), and many
1823- other operating systems support this functionality, including Windows.
1818+ Storage encryption can beperformed at the file system level or the
1819+ block level. Linux file system encryption options include eCryptfs
1820+ and EncFS, while FreeBSD uses PEFS. Block level or full disk
1821+ encryption options include dm-crypt + LUKS on Linux and GEOM
1822+ modules geli and gbde on FreeBSD. Many other operating systems
1823+ support this functionality, including Windows.
