(AutoIt) Get PDF DSS (Document Security Store)See more PDF Signatures ExamplesThis 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.
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. $oPdf = ObjCreate("Chilkat.Pdf") Local $bSuccess = $oPdf.LoadFile("qa_data/pdf/sign_testing_1/helloSigned2.pdf") If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf $oJson = ObjCreate("Chilkat.JsonObject") $oJson.EmitCompact = False $bSuccess = $oPdf.GetDss($oJson) ConsoleWrite($oJson.Emit() & @CRLF) ; The document security store contains certificates, OCSP responses, and CRLs. ; The following JSON is a sample of what the /DSS can contain. ; Unfortunately, our sample contains /Certs and /OCSPs, but no /CRLs. ; It's no problem because whatever JSON you get back, you can use the ; following online tool to generate code to parse. ; Generate Parsing Code from JSON ; The code generated by the online tool for this JSON is shown below.. ;
