<title>DESCRIPTION</title>

162
<command>&COMMANDNAME;</command> is a program to generate the
191
TLS and OpenPGP keys used by
192
<citerefentry><refentrytitle>mandos-client</refentrytitle>
164
<citerefentry><refentrytitle>password-request</refentrytitle>
193
165
<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

present in either <filename>/etc/keys/mandos</filename> or

for inclusion in <citerefentry><refentrytitle

>mandos-clients.conf</refentrytitle><manvolnum
363
>8</manvolnum></citerefentry>. The host name or the name
364
specified with the <option>--name</option> option is used
365
for the section header. All other options are ignored,
366
and no key is created. Note: white space is stripped from
367
the beginning and from the end of the password; See <xref

white space is not stripped from the password in any way.

390
When <option>--password</option> or
391
<option>--passfile</option> is given, this option will
392
prevent <command>&COMMANDNAME;</command> from calling
393
<command>ssh-keyscan</command> to get an SSH fingerprint
394
for this host and, if successful, output suitable config
395
options to use this fingerprint as a
396
<option>checker</option> option in the output. This is
397
otherwise the default behavior.

408
This program is a small utility to generate new TLS and OpenPGP
409
keys for new Mandos clients, and to generate sections for

inclusion in <filename>clients.conf</filename> on the server.
