/* Plugin for testing nbdkit_read_password().
* (See also test-read-password.sh and test-read-password-interactive.sh)
*
* This plugin takes two required parameters, "password" and "file".
*
* It reads a password using nbdkit_read_password(), ie. using one of
* the usual password mechanisms like password=-, password=-FD or
* others. It writes whatever password was read to the file.
*
* Using this plugin we can test that all the mechanisms supported by
* nbdkit_read_password() work. Note that libvirt since 10.0.0 uses
* the password=-FD method to pass secrets to nbdkit-ssh-plugin.
*
* This plugin never gets as far as serving data. It shuts down
* nbdkit in the .get_ready callback.
