// 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.)
Chilkat.StringBuilder sb = new Chilkat.StringBuilder();

// Load the eReceipt JSON into a StringBuilder object.
bool success = sb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8");
if (success == false) {
    Debug.WriteLine("Failed to load input file.");
    return;
}

// 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)
string uuid = sb.GetHash("sha256","hex_lower","utf-8");
Debug.WriteLine("eInvoicing UUID = " + uuid);
