Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' Note: This example requires Chilkat v9.5.0.92 or greater.
' (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sb = CreateObject("Chilkat.StringBuilder")

' Load the eReceipt JSON into a StringBuilder object.
success = sb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8")
If (success = 0) Then
    outFile.WriteLine("Failed to load input file.")
    WScript.Quit
End If

' Convert the contents of sb to the ITIDA canonical form.
' Always pass utf-8 for the 2nd arg.
success = sb.Encode("itida","utf-8")

' Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
' (always use utf-8)
uuid = sb.GetHash("sha256","hex_lower","utf-8")
outFile.WriteLine("eInvoicing UUID = " & uuid)
