Set a TLS Client Certificate from a PEM

See more Socket/SSL/TLS Examples

Demonstrates Socket.SetSslClientCertPem, which loads and configures a TLS client certificate and private key from PEM data or a PEM file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Background. Supply the PEM password when the private key is encrypted, and configure the client certificate before connecting. Use client certificates only for mutual TLS.
