' 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.)
set sb = Server.CreateObject("Chilkat_9_5_0.StringBuilder")
' Load the eReceipt JSON into a StringBuilder object.
success = sb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8")
If (success = 0) Then
Response.Write "<pre>" & Server.HTMLEncode( "Failed to load input file.") & "</pre>"
Response.End
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")
Response.Write "<pre>" & Server.HTMLEncode( "eInvoicing UUID = " & uuid) & "</pre>"
