    // 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.)
    sb := chilkat.NewStringBuilder()

    // Load the eReceipt JSON into a StringBuilder object.
    success := sb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8")
    if success == false {
        fmt.Println("Failed to load input file.")
        sb.DisposeStringBuilder()
        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)
    uuid := sb.GetHash("sha256","hex_lower","utf-8")
    fmt.Println("eInvoicing UUID = ", *uuid)

    sb.DisposeStringBuilder()
