A representation of the XML X509IssuerSerial element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. An X509IssuerSerial object contains an X.509 issuer distinguished name (DN) and serial number pair. The XML schema definition is defined as:

  <element name="X509IssuerSerial" type="ds:X509IssuerSerialType"/>
  <complexType name="X509IssuerSerialType">
    <sequence>
      <element name="X509IssuerName" type="string"/>
      <element name="X509SerialNumber" type="integer"/>
    </sequence>
  </complexType>

An X509IssuerSerial instance may be created by invoking the newX509IssuerSerial method of the KeyInfoFactory class, and passing it a String and BigInteger representing the X.500 DN and serial number. Here is an example of creating an X509IssuerSerial from the issuer DN and serial number of an existing X509Certificate:

KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM");
X509IssuerSerial issuer = factory.newX509IssuerSerial
    (cert.getIssuerX500Principal().getName(), cert.getSerialNumber());
