@ThreadSafe public class XMLSignatureValidationStage extends AbstractStage<Element>
A pipeline stage which validates the XML digital signature found on DOM Elements.

This stage requires the following properties be set prior to initialization:

  • verificationKey

If Element signatures are required, per signatureRequired, and an Element does not contain a signature than an ErrorStatus object is set on the Element.

If Element signatures are required to be valid, per isValidSignatureRequired(), and an Element signature is found to be invalid than an ErrorStatus object is set on the element. If signatures are not required to be valid and an Element signature is found to be invalid than an WarningStatus is set on the Element.
