    The document has been altered or corrupted since the Signature was applied

    oferlapid

      Using reader DC 17.012.20095 and a valid certificate stored in my Windows Certificate Store

      The certificate is trusted to Sign Documents or data as well as to Certify documents.

      I sign a simple text file exported to PDF by Microsoft Word

      As soon as signing is done I get to view the signed PDF in Reader DC and the signature is invalid

       

      Signature is INVALID.

      - The document has been altered or corrupted since the Signature was applied.

      - The document is signed by the current user.

       

      Have no clue how to fix this

       

      Edit: Signing with self created certificate works fine, so the issue is related to a purchased certificate from a trusted CA in which trust setting is explicitly permitting

      Sign documents or data

      Certify documents

      Other three options are denied:

      Execute dynamic content that is embedded in a certified document

      Execute high privilege JavaScript that are embedded in a certified document

      Perform priviledge system operations (networking, printing, file access, etc.)

       

      Please help

       

      Thank you
