[jira] [Created] (PDFBOX-5182) Detect whether a Signature is out of Date

Ranjeet Kuruvilla created PDFBOX-5182:
-----------------------------------------

             Summary: Detect whether a Signature is out of Date
                 Key: PDFBOX-5182
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5182
             Project: PDFBox
          Issue Type: New Feature
          Components: Preflight
    Affects Versions: 3.0.3 JBIG2
            Reporter: Ranjeet Kuruvilla


Acrobat can detect, if a Signature is invalid. In particular one can see, if a Signature is outdated. That can happen, when a person signs a Document and then changes a Textfield or a Checkbox or any other field.

 

It would be great, if one could detect, whether one could use PDFBox to detect whether a Signature has been invalidated.

 

I attached the sign one can see in Acrobat once a Signature is invalidated !Invalid Signature.png!
