Configure a Socket for Server-Side TLS

See more Socket/SSL/TLS Examples

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

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. A TLS listener presents the configured server certificate during the handshake. When client certificates are required, acceptable CA distinguished names are added before InitSslServer.
