(SQL Server) Get PDF DSS (Document Security Store)

See more PDF Signatures Examples

This example demonstrates how to extract the information from a PDF's DSS (Document Security Store), if a /DSS exists. (Just because a PDF is signed does not mean a /DSS will exists. In fact, the /DSS is typically created at the point of adding the 2nd or greater signature because the /DSS contains LTV (long term validation) information about the previous signature at the time of adding an additional signature.)

Note: This example requires Chilkat v9.5.0.85 or greater.
