Hello.

First, sorry for my english...

I'm using Java iText to certify PDF document and get control of changes
allowed in document. I want to only allow to append new digital signatures
over the certified document.

The PDF certified with
sap.setCertificationLevel(PdfSignatureAppearance.CERTIFIED_FORM_FILLING)
is verifiyng OK, either with iText and Adobe Reader if only changes allowed
are appended to the document.

But i don't know how can i check if the certification maintains his validity
(with iText) when changes not allowed have been added to the document
certified.

Is there any way to check the certification status with itext?

Many thanks.

  JC Guerrero
