// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

bool success;

// -------------------------------------------------------------------------
// Load a cert + private key from a PFX.
Chilkat.Cert cert = new Chilkat.Cert();

// -------------------------------------------------------------------------
// Create the XML that is to be signed.
// 
// The XML we're creating can be found at Sample Pre-Signed XML with BinarySecurityToken
// The online tool at http://tools.chilkat.io/xmlCreate.cshtml can be used to generate the following XML creation code.
