function chilkatExample() {

    var success = false;

    var cert = new chilkat.Cert();

    success = cert.LoadFromFile("qa_data/certs/testIcpBrasil.cer");
    if (success == false) {
        console.log(cert.LastErrorText);
        return;
    }

    // If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
    // then the Rfc822Name property returns XML.
    var subjectAltNameXml = cert.Rfc822Name;

    console.log(subjectAltNameXml);

    // Here's a sample of the subjectAltNameXml:

    // <SubjectAltName>
    //     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
    //     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</name>
    //     <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
    //     <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
    // </SubjectAltName>

    // The XML can be parsed like this:

    var xml = new chilkat.Xml();
    xml.LoadXml(subjectAltNameXml);

    var oid;
    var name;

    var i = 0;
    var count_i = xml.NumChildrenHavingTag("name");
    while (i < count_i) {
        xml.I = i;
        oid = xml.ChilkatPath("name[i]|(oid)");
        name = xml.GetChildContent("name[i]");
        console.log(oid + ": " + name);
        i = i+1;
    }
