    <p>With DNSSEC+DANE (if browsers add DANE support), the website
      owner can just use a self-signed TLS cert and create a TLSA record
      (DANE-EE mode) for the domain name which contains the hash of the
      self-signed cert. That's it.<br>
    </p>
    <p>Web browser just has to fetch the TLSA record (with DNSSEC
      validation), and then match the hash with the cert that the server
      sends during the TLS handshake. <br>
