LOCAL loSb
LOCAL lnSuccess
LOCAL lcUuid

* 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.)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSb = CreateObject('Chilkat.StringBuilder')

* Load the eReceipt JSON into a StringBuilder object.
lnSuccess = loSb.LoadFile("qa_data/itida/EReceipt_ex.json","utf-8")
IF (lnSuccess = 0) THEN
    ? "Failed to load input file."
    RELEASE loSb
    CANCEL
ENDIF

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

* Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
* (always use utf-8)
lcUuid = loSb.GetHash("sha256","hex_lower","utf-8")
? "eInvoicing UUID = " + lcUuid
