## Interface X509IssuerSerial

- All Superinterfaces:
    `XMLStructure`

      public interface X509IssuerSerial
      extends XMLStructure

  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());
