Class Reference


public class Reference extends SignatureElementProxy
Handles <ds:Reference> elements. This includes: Construct a ds:Reference from an Element.

Create a new reference

 Document doc;
 MessageDigestAlgorithm sha1 = MessageDigestAlgorithm.getInstance("http://#sha1");
 Reference ref = new Reference(new XMLSignatureInput(new FileInputStream("1.gif"),
                               "http://localhost/1.gif",
                               (Transforms) null, sha1);
 Element refElem = ref.toElement(doc);
 

Verify a reference

 Element refElem = doc.getElement("Reference"); // PSEUDO
 Reference ref = new Reference(refElem);
 String url = ref.getURI();
 ref.setData(new XMLSignatureInput(new FileInputStream(url)));
 if (ref.verify()) {
    System.out.println("verified");
 }
