// 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:
// <samlp:AuthnRequest
// xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol"
// xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
// ID="pfx41d8ef22-e612-8c50-9960-1b16f15741b3"
// Version="2.0" ProviderName="SP test" IssueInstant="2014-07-16T23:52:45Z"
// Destination="http://idp.example.com/SSOService.php"
// ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"
// AssertionConsumerServiceURL="http://sp.example.com/demo1/index.php?acs">
// <saml:Issuer>http://sp.example.com/demo1/metadata.php</saml:Issuer>
