        <dd>Callback to invoke when OpenSSL needs to obtain a password,
	    typically to unlock the private key of a certificate. The
            callback should return a string which represents the password
            to be used. See <a href="#CALLBACK OPTIONS">CALLBACK OPTIONS</a>

        <dt><strong>-require</strong> <em>bool</em></dt>
        <dd>Require a valid certificate from peer during SSL handshake.
