// Create a TLS configuration with cipher suites, certificates and rootCAs. config := &tls.Config{ CipherSuites: []uint16{ tls.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, tls.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, tls.TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, tls.TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, }, Certificates: []tls.Certificate{cert}, RootCAs: rootCAs, } // Create a TLS client with the configuration client := &http.Client{ Transport: &http.Transport{ TLSClientConfig: config, }, } // Make a GET request with the client resp, err := client.Get("https://example.com/") if err != nil { log.Fatal(err) } defer resp.Body.Close()In this example, we create a TLS configuration with specified cipher suites, certificates, and rootCAs. We then create a TLS client with the configuration and make a GET request with the client. If there is any error, we log it and close the response body. Overall, the go crypto.tls Config package library is quite powerful and flexible for configuring TLS connections in Go, making it easier to secure connections over the Internet.
