<dd><p>Prompts for a password (press enter for a random password) and writes TLS-SRP authentication files into the directory given by:
</p>
<p><code>fullfile (a = pkg (&quot;prefix&quot;), &quot;parallel-srp-data&quot;)</code>
</p>
<p>Server files are placed in subdirectory <code>server</code>. By default, a
client authentication file is placed in subdirectory
<code>client</code>. The latter contains the given <var>username</var> and the
cleartext password. You do not need this file if you prefer to be
prompted for username and password at connection time. In this case,
you can prevent the client authentication file from being written by
passing as the argument <var>options</var> a structure with a value of
<code>false</code> in the field <code>unattended</code>.
</p>
<p>For authentication, subdir <code>server</code>, and possibly subdir
<code>client</code>, have to be placed together with their contents at the
respective machines. They can either be placed under the directory
given by:
</p>
<p><code>fullfile (OCTAVE_HOME (), &quot;share&quot;, &quot;octave&quot;, &quot;parallel-srp-data&quot;)</code>
</p>
<p>or &ndash; which might be the same directory &ndash; under:
</p>
<p><code>fullfile (a = pkg (&quot;prefix&quot;), &quot;parallel-srp-data&quot;)</code>
</p>
<p>Files in the former directory will take precedence over those in the
latter. The contents of the files <code>passwd</code> and <code>user_passwd</code>
(if present) must be kept secret.
</p>
<p>This function zeroizes sensitive data before releasing its memory. Due
to usage of external libraries, however, it still can&rsquo;t be excluded
that sensitive data is still on the swap device after application
shutdown.
