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

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
