; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.
; This example will sign the following SAML AuthNRequest:

; xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"

; Version="2.0" ProviderName="SP test" IssueInstant="2014-07-16T23:52:45Z"
; Destination="http://idp.example.com/SSOService.php"
