    // 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.)
    var sb = new chilkat.StringBuilder();

    // Load the eReceipt JSON into a StringBuilder object.

    }

    // 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)
    var uuid = sb.GetHash("sha256","hex_lower","utf-8");
    console.log("eInvoicing UUID = " + uuid);
