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());
 
```
