Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate.

    //  must have the associated private key available. (.pfx/.p12 files typically store both
    //  the certificate and associated private key.)
