%description
cryptsetup is used to conveniently setup up dm-crypt based
device-mapper targets. It can set up targets to read cryptoloop
compatible volumes as well as LUKS formatted ones. The package
additionally includes support for automatically setting up encrypted
volumes at boot time via the config file /etc/crypttab

CRYPTTAB(5)
===========
NAME
----
crypttab - static information about crypted filesystems
SYNOPSIS
--------
*crypttab*::
'<target device>' '<source device>' '<key file>' '<options>'
DESCRIPTION
-----------
The file */etc/crypttab* 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 *crypttab* is important because the
*/etc/init.d/boot.crypto* script sequentially iterates through
*crypttab* entries. All four columns are mandatory, missing or
excessive columns will lead to unspecified behaviour.
- The first column, 'target device' specifies the mapped 'device
name'. It must be a plain filename without any directories. A mapped
device */dev/mapper/*'device name' will be created by
*cryptsetup(8)* crypting data from and onto the 'source device'.
To actually mount that device it needs to be listed in */etc/fstab*.
- The second column 'source device' specifies the block special
device that should hold the encrypted data.
- The third column 'key file' specifies the file to use for
decrypting the encrypted data of the 'source device'.
It can also be a device name (e.g. */dev/urandom*, which is useful
for encrypted swap devices). Warning: luks does not support infinite
streams (like */dev/urandom*), it requires a fixed size key.
If the 'key file' is the string *none*, the key data (i.e. a
password or passphrase) will be read interactively from the console.
In this case the options precheck, check, checkargs and tries may be
useful.
- The fourth field 'options' specifies the cryptsetup options
associated with the encryption process. At minimum, the field should
contain the string *luks* or the 'cipher', 'hash' and 'size'
options.
Options have to be specified in the format: 'key'='value'[,'key'='value' ...]
OPTIONS
-------
*cipher*=<cipher>::
Encryption algorithm. See *cryptsetup -c*.
*size*=<size>::
Encryption key size. See *cryptsetup -s*.
*hash*=<hash>::
Hash algorithm. See *cryptsetup -h*.
*verify*::
Verify password. See *cryptsetup -y*.
*readonly*::
The backing device is read-only (eg: a dvd).
*luks*::
Use device with luks extensions.
*swap*::
Run *mkswap* on the created device.
*tmp*::
Run *mkfs* on the created device. The file system to use is
specified in */etc/fstab*. If */etc/fstab* does not list the mapped
device, ext2 is used as fallback.
*precheck*=<precheck>::
Check the source device by suitable program; if the check fails the device is
not created; <precheck> is a script to check the source device. The source
device is given as argument to the script.
*check*[=<program>]::
Check the content of the mapped device by a suitable program; if the
check fails the device is removed. The specified program is
run giving the decrypted volume (target device) as first and the
value of the checkargs option as second argument. Cryptdisks
searches for the given program in /lib/cryptsetup/checks/. If no
program is specified, vol_id is used.
*checkargs*=<argument>::
Pass <argument> as second argument to the check script
*tries*=<num>::
Prompt for the passphrase at most <num> times if the entered
passphrase was wrong. Defaults is 3. Only works for LUKS volumes.
*timeout*=<sec>::
Time out interactive password prompts after <sec> seconds.
*loop*::
Always attach a loop device before mapping the device. Normally a
loop device is used automatically only for image files. Useful if
the block size of the physical device does not match the block size
of the contained file system. E.g. ext2 on a CD.
*noauto*::
Causes boot.crypto to skip this record during boot
*pseed=<string>*::
Set a string that is appended to the passphrase after hashing.
Using different seeds for volumes with the same passphrase makes
dictionary attacks harder. Use for compatability with loop-AES.
*itercountk=<num>*::
Encrypts the hashed password <num> thousand times using AES-256. Use
for compatability with loop-AES.
*loud*, *ssl*, *gpg*, *keyscript*::
not supported. Listed here as they are supported by Debian.
CHECKSCRIPTS
------------
TODO
/////
*vol_id*::
Checks for any known filesystem. Supports a filesystem type as argument via
<checkargs>:
no checkargs - succeeds if any valid filesystem is found on the device.
"none" - succeeds if no valid filesystem is found on the device.
"ext3" [or any other filesystem type like xfs, swap, crypto_LUKS, whatever] - succeeds
if an ext3 [or another given] filesystem type is found on the device.
*ext3*::
Checks for a valid ext2/ext3 filesystem.
*xfs*::
Checks for a valid xfs filesystem.
*swap*::
Checks for partition type 'swap'. Only useful as <precheck>.
////
EXAMPLES
--------
*Encrypted swap device*::
cswap /dev/sda6 /dev/random swap
*Encrypted luks volume with interactive password*::
cdisk0 /dev/hda1 none luks
*Encrypted luks volume with interactive password, use a custom check script, no retries*::
cdisk2 /dev/hdc1 none luks,check=customscript,checkargs=foo,tries=1
*Encrypted volume with interactive password and a cryptoloop compatible twofish256 cipher*::
cdisk3 /dev/sda3 none cipher=twofish-cbc-plain,size=256,hash=sha512
