; See Global Unlock Sample for sample code.

; In this example, the URLs for the DigiCert root CA certs are available at this web page:

; This example downloads the "DigiCert Global Root G3"
; Valid until: 15/Jan/2038
; Serial #: 05:55:56:BC:F2:5E:A4:35:35:C3:A4:0F:D5:AB:45:72

; Output from the above:

; to be downloaded from the website every time.

; Do the following to add the cert to the collection of trusted roots
; for this application.  (Note:  The trust is not persisted.  Each time the
; application runs, it should load the cert (from whatever source, whether it is
; a file, a database,etc.) and do the following:
$oTroots = ObjCreate("Chilkat.TrustedRoots")

$oTroots.AddCert($oCert)
$oTroots.Activate()
