Get the Configured Server-Side TLS Certificate

See more Socket/SSL/TLS Examples

Demonstrates Socket.GetMyServerCert, which copies the TLS server certificate configured by InitSslServer into a Cert object.

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. This is intended for a socket acting as a TLS server and returns false when no server certificate has been configured.
