(description
|
||
"Cryptsetup is a utility used to conveniently set up disk encryption based
|
||
on the @code{dm-crypt} Linux kernel module. It is most often used to manage
|
||
LUKS volumes but also supports plain dm-crypt volumes and loop-AES, TrueCrypt
|
||
(including VeraCrypt extension), and BitLocker formats.
|
||
|
||
@acronym{LUKS, Linux Unified Key Setup} is the standard for hard disk encryption
|
||
with the kernel Linux. It provides a standard on-disk-format compatible amongst
|
||
distributions as well as secure management of multiple user passwords. LUKS
|
||
stores all necessary setup information in the partition header to facilitate
|
||
data transport and migration.
|
||
|
||
The package also includes the @command{veritysetup} and @command{integritysetup}
|
||
utilities to conveniently configure the @code{dm-verity} and @code{dm-integrity}
|
||
block integrity kernel modules.")
