The <code class="Fn">zip_file_set_encryption</code>() function sets the
  encryption method for the file at position <var class="Ar">index</var> in the
  zip archive to <var class="Ar">method</var> using the password
  <var class="Ar">password</var>. The <var class="Ar">method</var> is the same
  as returned by <a class="Xr" href="zip_stat.html">zip_stat(3)</a>. For the
  <var class="Ar">method</var> argument, currently only the following values are
  supported:
<dl class="Bl-tag">
  <dt><a class="permalink" href="#ZIP_EM_NONE"><code class="Dv" id="ZIP_EM_NONE">ZIP_EM_NONE</code></a></dt>
