(JavaScript) Create AuthNRequest with embedded signature (HTTP-POST binding)
Demonstrates how to create a SAML AuthNRequest with embedded signature (HTTP-POST binding).
var success = false;
// 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>
// <samlp:NameIDPolicy Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" AllowCreate="true"/>
// <samlp:RequestedAuthnContext Comparison="exact">
// <saml:AuthnContextClassRef>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</saml:AuthnContextClassRef>
// </samlp:RequestedAuthnContext>
// </samlp:AuthnRequest>
// First we build the XML to be signed.
//
// Use this online tool to generate the code from sample XML:
// Generate Code to Create XML
