# 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 = New-Object Chilkat.StringBuilder

# Load the eReceipt JSON into a StringBuilder object.
$success = $sb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8")
if ($success -eq $false) {
    $("Failed to load input file.")
    exit
}

# 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")
