Dear Adobe Acrobat Team, I am adding an annotation and a digital signature to a pdf document through my being-developed application, however when open that pdf with adobe acrobat, it validates the signature, and reports that "Annotations Modified" under the validated signature in the signatures panel, so why do acrobat behaves that way?
Yes lrosenth, that's true, but even with document that has the comment in in an update table ( in an incremental update section ) before
the the incremental update of the digital signature, the same probelm appears?
Can you please have a look at an example of such document at:
No, the certificate is trusted and it is in the store of trusted certificate; Adobe is validating the signature and it says it is valid.
So the problem is related to how adobe verifies that no updates were applied to the document after the signature is applied;
depending on signautre timestamp, annotation creation time, document metadata, ... etc.
Thank you very much.
I am still seeing that the signature in Sample2 only applies to the original and NOT to do the annotated version. You can see this because Acrobat clearly allows you to pull the original version, which does NOT have the signature.
