  36  * QCryptoTLSCredsAnon:
  37  *
  38  * The QCryptoTLSCredsAnon object provides a representation
  39  * of anonymous credentials used perform a TLS handshake.
  40  * This is primarily provided for backwards compatibility and
  41  * its use is discouraged as it has poor security characteristics
  42  * due to lacking MITM attack protection amongst other problems.
  43  *
  44  * This is a user creatable object, which can be instantiated
  45  * via object_new_propv():
  46  *
  47  * <example>
  48  *   <title>Creating anonymous TLS credential objects in code</title>
  49  *   <programlisting>
