    Welcome to <i>GnuTLS</i> project pages
  </p>
<ul>
  <li><a name="overview"><b>Overview</b></a>
    <p> GnuTLS is a secure communications library implementing the <a href="http://datatracker.ietf.org/wg/tls/charter/">SSL, TLS and DTLS protocols</a>
        and technologies around them. It provides a simple C language application programming interface (API) 
        to access the secure communications protocols as well as APIs to parse and
        write X.509, PKCS #12, OpenPGP and other required structures. It is
        aimed to be portable and efficient with focus on security and interoperability.
