(AutoIt) Sign a PDF (Simplest Possible Example)See more PDF Signatures ExamplesThis example demonstrates how to a sign a PDF using mostly default options in the simplest way possible.
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. $oPdf = ObjCreate("Chilkat.Pdf") ; Load a PDF to be signed. ; The "hello.pdf" is available at https://chilkatsoft.com/hello.pdf Local $bSuccess = $oPdf.LoadFile("qa_data/pdf/hello.pdf") If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf ; Options for signing are specified in JSON. $oJson = ObjCreate("Chilkat.JsonObject") ; In most cases, the signingCertificateV2 and signingTime attributes are required. $oJson.UpdateInt("signingCertificateV2",1) $oJson.UpdateInt("signingTime",1) ; Put the signature on page 1, top left $oJson.UpdateInt("page",1) $oJson.UpdateString("appearance.y","top") $oJson.UpdateString("appearance.x","left") ; Use a font scale of 10.0 $oJson.UpdateString("appearance.fontScale","10.0") ; In this example, the appearance of the digital signature will contain three lines: ; 1) The signing certificate's common name ; 2) The current date/time ; 3) Some arbitrary text. ; The keyword "cert_cn" is replaced with the Certificate's Subject Common Name. ; The keyword "current_dt" is replaced with the current date/time. ; Any number of appearance text lines can be added. $oJson.UpdateString("appearance.text[0]","Digitally signed by: cert_cn") $oJson.UpdateString("appearance.text[1]","current_dt") $oJson.UpdateString("appearance.text[2]","The crazy brown fox jumps over the lazy dog.") ; Load the signing certificate. (Use your own certificate.) $oCert = ObjCreate("Chilkat.Cert") $bSuccess = $oCert.LoadPfxFile("qa_data/pfx/myPdfSigningCert.pfx","secret") If ($bSuccess = False) Then ConsoleWrite($oCert.LastErrorText & @CRLF) Exit EndIf ; Tell the pdf object to use the certificate for signing. $bSuccess = $oPdf.SetSigningCert($oCert) If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf $bSuccess = $oPdf.SignPdf($oJson,"qa_output/hello_signed.pdf") If ($bSuccess = False) Then ConsoleWrite($oPdf.LastErrorText & @CRLF) Exit EndIf ConsoleWrite("The PDF has been successfully cryptographically signed." & @CRLF) ; The appearance of the signature appears in Adobe Acrobat as shown here: |
