<p>Creates a self private X.509 key. Generating secure keys needs quite
some time. Call <code class="function">epc_tls_set_private_key_hooks()</code> to install hooks providing
some feedback to your users. Key generation takes place in a separate

for instance the GTK+ widget system remains responsible during that
phase.</p>
