<command>&COMMANDNAME;</command> is a program to generate the
191
TLS and OpenPGP keys used by
192
<citerefentry><refentrytitle>mandos-client</refentrytitle>
162
<citerefentry><refentrytitle>password-request</refentrytitle>
193
163
<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
194
normally written to /etc/keys/mandos for later installation into
195
the initrd image, but this, and most other things, can be
196
changed with command line options.
199
This program can also be used with the
200
<option>--password</option> or <option>--passfile</option>
201
options to generate a ready-made section for
202
<filename>clients.conf</filename> (see
203
<citerefentry><refentrytitle>mandos-clients.conf</refentrytitle>
204
<manvolnum>5</manvolnum></citerefentry>).
164
normally written to /etc/mandos for later installation into the

initrd image, but this, like most things, can be changed with
166
command line options.
