Demonstrates how to access the multiple names contained in the Subject Alternative Name of a certificate. This example is for an ICP Brasil certificate. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkCert cert = new CkCert();

    success = cert.LoadFromFile("qa_data/certs/testIcpBrasil.cer");
    if (success == false) {
        System.out.println(cert.lastErrorText());
        return;
        }

    // If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
    // then the Rfc822Name property returns XML.
    String subjectAltNameXml = cert.rfc822Name();

    System.out.println(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:

    CkXml xml = new CkXml();
    xml.LoadXml(subjectAltNameXml);

    String oid;
    String name;

    int i = 0;
    int count_i = xml.NumChildrenHavingTag("name");
    while (i < count_i) {
        xml.put_I(i);
        oid = xml.chilkatPath("name[i]|(oid)");
        name = xml.getChildContent("name[i]");
        System.out.println(oid + ": " + name);
        i = i+1;
        }
  }
