Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication. Xbase++

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

//  On Windows, a pre-installed certificate can be loaded in a number of different ways.
//  This example loads by the common name:
oCert := CreateObject("Chilkat.Cert")
nSuccess := oCert:LoadByCommonName("My ECA Medium Assurance Identity Certificate")

//  Make sure this certificate has a private key available.  
//  It should be a private key such that when the certificate was installed, it was marked as "exportable"
//  so that authorized programs are able to access the private key.

//  (i.e. sets the client-side certificate for two-way TLS authentication)

//  At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
//  connection will automatically use it if the server demands a client-side cert.
