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. PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Crypt
oleobject loo_CmsOptions
string ls_OutputFile
string ls_InFile

li_Success = 0

loo_Crypt = create oleobject
li_rc = loo_Crypt.ConnectToNewObject("Chilkat.Crypt2")
if li_rc < 0 then
    destroy loo_Crypt
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Tell Chilkat to also validate the timestamp token if a timestamp exists in the CMS message's unauthenticated attributes.
loo_CmsOptions = create oleobject
li_rc = loo_CmsOptions.ConnectToNewObject("Chilkat.JsonObject")

loo_CmsOptions.UpdateBool("ValidateTimestampTokens",1)
loo_Crypt.CmsOptions = loo_CmsOptions.Emit()

ls_OutputFile = "qa_output/original.xml"
ls_InFile = "qa_data/p7m/fattura_signature.xml.p7m"

// Verify the signature and extract the contained file, which in this case is XML.
li_Success = loo_Crypt.VerifyP7M(ls_InFile,ls_OutputFile)
if li_Success = 0 then
    Write-Debug loo_Crypt.LastErrorText
    destroy loo_Crypt
    destroy loo_CmsOptions
    return
end if

Write-Debug "Signature validated."
