public IList<SignatureValidationError> Validate()
Public Function Validate As IList(Of SignatureValidationError)
A list of possible errors. If there are not errors, returns an empty list.
DotPdf does not validate the content of the X509 certificates that were used to
sign the document. How that should be done is strictly up to client code. This
method instead will look at the aspects of the document that are not controlled
by the signining certificates. For example, did a program modify the PDF document in a
way that was forbidden by either the document's Certification or by one or more SignatureWidgetAnnotation\
objects within the document.
