# salt.modules.cryptdev

Salt module to manage Unix cryptsetup jobs and the crypttab file

Added in version 2018.3.0.

salt.modules.cryptdev.active()

  List existing device-mapper device details.

salt.modules.cryptdev.close(name)

  Close a crypt device using `cryptsetup`.

  CLI Example:

      salt '*' cryptdev.close foo

salt.modules.cryptdev.crypttab(config='/etc/crypttab')

  List the contents of the crypttab

  CLI Example:

      salt '*' cryptdev.crypttab

salt.modules.cryptdev.open(name, device, keyfile)

  Open a crypt device using `cryptsetup`. The `keyfile` must not be `None` or `'none'`, because `cryptsetup` will otherwise ask for the password interactively.

  CLI Example:

      salt '*' cryptdev.open foo /dev/sdz1 /path/to/keyfile

salt.modules.cryptdev.rm_crypttab(name, config='/etc/crypttab')

  Remove the named mapping from the crypttab. If the described entry does not exist, nothing is changed, but the command succeeds by returning `'absent'`. If a line is removed, it returns `'change'`.

  CLI Example:

      salt '*' cryptdev.rm_crypttab foo

salt.modules.cryptdev.set_crypttab(name, device, password='none', options='', config='/etc/crypttab', test=False, match_on='name')

  Verify that this device is represented in the crypttab, change the device to match the name passed, or add the name if it is not present.

  CLI Example:

      salt '*' cryptdev.set_crypttab foo /dev/sdz1 mypassword swap,size=256
