HTTPS – setting up a TLS server

To start a TLS server, you need a certificate and a private key. You can either purchase one from a CA or generate our own certificates with your internal CA. Once you have your certificate, you can use the recipes in this section to start your HTTPS server.

How to do it...

To create a TLS HTTP server, use one of the following:

1. Use the Server.ListenAndServeTLS method with the certificate and key files:

   server := http.Server {
      Addr: ":4443",
      Handler: handler,
   }
   server.ListenAndServeTLS("cert.pem", "key.pem")

2. To use the default HTTP server, set a handler function (or http.Handler) and call http.ListenAndServeTLS:

   http.HandleFunc("/",func(w http.ResponseWriter, req *http.Request) {
     // Handle request
   })
   http.ListenAndServeTLS("cert.pem", "key.pem")

3. Or prepare a http.Transport with certificates:
