Now change these lines in the IRCd config file:

    ssl_private_key = "${relative_sysconfdir}/ssl.key";
    ssl_cert = "${relative_sysconfdir}/ssl.pem";
    ssl_dh_params = "${relative_sysconfdir}/dh.pem";

If you want to get your certificate signed by a certificate authority,
submit the ssl.csr file to your CA, then replace ssl.pem with the
certificate returned to you. You may need to include your CA's
intermediate certificates in signing order.

Enjoy using ssl.
