CRYPTOTAB(5) Cryptsetup Manual CRYPTOTAB(5)NAME
cryptotab - static information about crypted filesystems (deprecated)
SYNOPSIS
cryptotab
LOOPDEVICE DEVICE MOUNTPOINT FILESYSTEM ALGORITHM[ MOUNTOPTIONS[
INFO]]
DESCRIPTION
Note
/etc/cryptotab was designed for use with the now deprecated
cryptoloop technology and must therefore be considered deprecated
as well. /etc/crypttab (note the missing “o”) should be used
instead.
The file /etc/cryptotab contains descriptive informations about
encrypted volumes. Each volume is described on a separate line; columns
on each line are separated by tabs or spaces. Lines starting with "#"
are comments, empty lines are ignored. The order of records in
cryptotab is important because the /etc/init.d/boot.crypto script
sequentially iterates through cryptotab entries.
LOOPDEVICE specifies the loop device
to use for this mapping,
for example /dev/loop0
DEVICE specifies the block
special device that holds
the encrypted data
MOUNTPOINT specifies the where the
volume should be mounted
FILESYSTEM specifies the file system
of the volume
ALGORITHM specifies the encryption
algorithm to use
Supported algorithms are
twofish, twofishSL92 and
twofish256
MOUNTOPTIONS optionally specifies mount
option
INFO optionally specifies a
string that should be
printed when prompting for
the passphrase
EXAMPLES
/dev/loop0 /dev/sda6 /secret ext2 twofish256
