Verify the Timestamp Server Token (if any) while Validating a CMS Signature

Demonstrates how to also validate the timestamp server token (if any) while validating a CMS signature. VBScript

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set crypt = CreateObject("Chilkat.Crypt2")

' Tell Chilkat to also validate the timestamp token if a timestamp exists in the CMS message's unauthenticated attributes.
set cmsOptions = CreateObject("Chilkat.JsonObject")
success = cmsOptions.UpdateBool("ValidateTimestampTokens",1)
crypt.CmsOptions = cmsOptions.Emit()

outputFile = "qa_output/original.xml"
inFile = "qa_data/p7m/fattura_signature.xml.p7m"

' Verify the signature and extract the contained file, which in this case is XML.
success = crypt.VerifyP7M(inFile,outputFile)
If (success = 0) Then
    outFile.WriteLine(crypt.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("Signature validated.")

outFile.Close
