NAME
       askpass-fifo - Mandos plugin to get a password from a FIFO.


SYNOPSIS
       askpass-fifo


DESCRIPTION
       This program reads a password from a FIFO and outputs it to standard output.

       This program is not very useful on its own. This program is really meant to run as a plugin in the Mandos
       client-side system, where it is used as a fallback and alternative to retrieving passwords from a Mandos
       server.

       This program is meant to be imitate a feature of the askpass program, so that programs written to
       interface with it can keep working under the Mandos system.


OPTIONS
       This program takes no options.


EXIT STATUS
       If exit status is 0, the output from the program is the password as it was read. Otherwise, if exit
       status is other than 0, the program was interrupted or encountered an error, and any output so far could
       be corrupt and/or truncated, and should therefore be ignored.


FILES
       /lib/cryptsetup/passfifo
           This is the FIFO where this program will read the password. If it does not exist, it will be created.


EXAMPLE
       Note that normally, this program will not be invoked directly, but instead started by the Mandos plugin-
       runner(8mandos).

       This program takes no options.

SECURITY
       The only thing that could be considered worthy of note is this: This program is meant to be run by
       plugin-runner(8mandos), and will, when run standalone, outside, in a normal environment, immediately
       output on its standard output any presumably secret password it just received. Therefore, when running
       this program standalone (which should never normally be done), take care not to type in any real secret
       password by force of habit, since it would then immediately be shown as output.
