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.
