Dim success As Boolean = False

'  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.)
Dim sb As ChilkatStringBuilder
sb.Initialize

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


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

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