PdfDocumentSignature Class

The PdfDocumentSignature class represents the data needed for applying a digital signature to an existing SignatureWidgetAnnotation object in a PdfDocument. This means that the SignatureWidgetAnnotation must already exist in the PagesOfAnnotations property in the PdfDocumentSigner either because it was pre-existing in the original document or that the document allowed it to be added.
