fsencrypt

Runs on:

QNX OS

Options:

-c cmd

The command to run (see below).

-d domain

The domain number to be used (0–100). Set the domain to 0 to remove encryption.

-f

If path is a directory, make the move or remove action on the files as well.

-K key

Specify a secondary key, in the same form as for -k.

-k key

Specify key data in one of the following forms:

• .[salt.]str — an optional 64-bit salt value expressed as a string of up to 16 hexadecimal digits, followed by a period and a plain-text string.
• :setup — a command string used with the setup command. The string format is:

  domain:type:locked:provider:path

• +str — a user-supplied plain-text string, to be hashed into a 512-bit key
• #str — A base-64 representation of the raw key. The length of the provided string must be a multiple of 4 characters. If str is shorter than the key size for the encryption type identified with the -t option, the key is padded with zeroes.
• @file — the name of a file that contains binary key data. The length of the key depends on the encryption type; see the description of the -t option.

-l log_path

The path of the log file to use (stdout is the default).

-n value

Specify a secondary value that some commands require.

-o offset

(oh) An offset into a key file specified with the -K@ or -k@ option.

-p path

The mountpoint of a Power-Safe (fs-qnx6.so) filesystem, or a file in the filesystem, depending on the command.

-r

If path is a directory, take action on the entire tree.

-t type

Identify the encryption mechanism. The supported types include:

type	Key length	Description
0	Not applicable	No encryption
1	512 bits	AES-256, in XTS mode. The two keys are randomly generated.
2	256 bits	AES-256, in CBC mode

-v[v...]

Be verbose; each v increases the level of verbosity. If you don't turn on verbosity, some commands indicate success or failure only by fsencrypt's exit status.

Description:

The fsencrypt utility manages the encryption of a Power-Safe (fs-qnx6.so) filesystem. In order to use fsencrypt, you must have specified crypto=enable for fs-qnx6.so.

The commands that you can specify with the -c option are given below, along with the other options that you must specify for each command:

change-key

Change a domain key:

fsencrypt -p path -c change-key -d domain -k old_key -K new_key -t type

check

Check for support of encryption on a given filesystem:

fsencrypt -p path -c check

check-key

Verify that the key given is valid against a domain:

fsencrypt -p path -c check-key -d domain -k key -t type

create

Create a domain:

fsencrypt -p path -c create -d domain -k key -t type

The new domain is unlocked.

destroy

Destroy a domain:

fsencrypt -p path -c destroy -d domain

You must be in the group that owns the mountpoint.

CAUTION:

If you destroy a domain, you won't be able to access any of its contents because they'll be encrypted and the domain's encryption key will have been destroyed. The contents remain in the filesystem until you delete them.

enable

Enable encryption support on a volume that wasn't set up for it at formatting time:

fsencrypt -p path -c enable

get

Determine the domain that the given path belongs to:

fsencrypt -p path -c get

lock

Lock a domain within the given filesystem:

fsencrypt -p path -c lock -d domain

migrate-delay

Change the migration delay between work units. Use the -n option to indicate a period in milliseconds:

fsencrypt -p path -c migrate-delay -n milliseconds

migrate-path

Parse a path, assigning the given domain to directories and tagging files to the given domain:

fsencrypt -p path -c migrate-path -d domain

Note:

In order for you to tag files for migration, the source and destination domains must be unlocked.

migrate-state

Determine the amount of remaining migration work:

fsencrypt -p path -c migrate-state

migrate-start

Start the background encryption of tagged files:

fsencrypt -p path -c migrate-start

migrate-status

Report the status of migration:

fsencrypt -p path -c migrate-status

migrate-stop

Suspend the background encryption migration:

fsencrypt -p path -migrate-stop

migrate-tag

Tag a file for migration into the given domain (tag is a synonym):

fsencrypt -p file -c migrate-tag -d domain

Note:

In order for you to tag a file for migration, the source and destination domains must be unlocked.

migrate-units

Set the amount of work to complete beween delay periods. Use the -n option to indicate a number of blocks:

fsencrypt -p path -c migrate-units -n blocks

query

Query the status of a domain:

fsencrypt -p path -c query -d domain

query-all

Query the status of all the domains for a filesystem:

fsencrypt -p path -c query-all

read-key

Read a file key into file:

fsencrypt -p path -c read-key -k @file

set

Assign the given path to a numbered domain:

fsencrypt -p path -c set -d domain

The domain must be unlocked. Regular files must have a length of zero. The domain replaces any domain previously assigned to the path.

setup

Complete the domain setup based on the provided -k :str option:

fsencrypt -p path -c setup -k :domain:type:locked:provider:path

tag

Tag a file for migration into the given domain (migrate-tag is a synonym):

fsencrypt -p file -c tag -d domain

Note:

In order for you to tag a file for migration, the source and destination domains must be unlocked.

unlock

Unlock a domain, given the correct key data:

fsencrypt -p path -c unlock -d domain -k key -t type

Examples:

fsencrypt -vc create -d10 -t1 -p/ -k.1234567890abcdef.mypassword

fsencrypt -vc unlock -d10 -t1 -p/ -k.1234567890abcdef.mypassword

fsencrypt -vc set -d10 -p/secure_dir

Exit status:

0

Success.

> 0

An error occurred.
