<title>DESCRIPTION</title>

159

<para>

160

<command>&COMMANDNAME;</command> is a program to generate the

161

OpenPGP key used by

162

<citerefentry><refentrytitle>password-request</refentrytitle>

163

<manvolnum>8mandos</manvolnum></citerefentry>. The key is

164

normally written to /etc/mandos for later installation into the

165

initrd image, but this, and most other things, can be changed

166

with command line options.

167

</para>

168

<para>

169

This program can also be used with the

171

section for <filename>clients.conf</filename> (see

172

<citerefentry><refentrytitle>mandos-clients.conf</refentrytitle>

<manvolnum>5</manvolnum></citerefentry>).
