Can a digitally signed document with appropriate document security, i.e., Information Rights Management, can be changed to add users to view document? RRS feed

  • Question

  • We are experimenting of using Information Rights Management (IRM) in a Word Document that was digitally signed.  If I get to define 5 users to view the document, can I add users to view the same document without invalidating the digital signatures?

  • No, if you sign apply IRM protection to a signed document you need to resign it. After applying IRM protection the file changes and the signature would be invalid. Therefore you need to remove the signature first, apply RMS protection and then sign the document.
