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
