<command>&COMMANDNAME;</command> is a program to generate the
190
TLS and OpenPGP keys used by
191
<citerefentry><refentrytitle>mandos-client</refentrytitle>
163
<citerefentry><refentrytitle>password-request</refentrytitle>
192
164
<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
193
165
normally written to /etc/mandos for later installation into the
194
initrd image, but this, and most other things, can be changed
195
with command line options.
198
This program can also be used with the
199
<option>--password</option> or <option>--passfile</option>
200
options to generate a ready-made section for
201
<filename>clients.conf</filename> (see

167
command line options.
