Use HTTPS Client Certificate from .cer and .key Files

Demonstrates how to load a cert + private key from .cer and .key (base64) files and use it for mutual TLS authentication (client-side certificate). C++

    //  Set the certificate to be used for mutual TLS authentication
    //  (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.
