I am interested to know what happens to a PDF that has been Reader Extended with signed Digital Signature (PKI) information within it. In this use case, the document is filled, locked (using PKI signature) and is stored in a suitable document management system.
What happens to the PDF / data after the RE credential expires?
Is it still accessible / readable / printable as a PDF?
Is there a way to archive a R/E PDF with PKI signatures without removing the information?
