![]() ![]() Go manages the default behavior and functionality of the TLS communication. That's it! This is what most people have to do to launch an HTTPS server. $ curl https : //localhost:8443/ -cacert rootCA.crt -key client.key -cert client.crt Now that you have both private key and certificate files, you can modify your earlier Go program and use the ListenAndServeTLS method instead. crt -days 500 -sha256įinally, follow the same steps for generating certificates for each server to generate certificates for clients. Generate the certificate using the TSL CSR and key along with the CA Root key: openssl x509 -req -in localhost. When creating the CSR, it is important to specify the Common Name providing the IP address or domain name for the service, otherwise the certificate cannot be verified. The owner of the root key will process this request to generate the certificate. The CSR is where you specify the details for the certificate you want to generate. Create the certificate-signing request (CSR). ![]() Create the certificate key: openssl genrsa -out localhost. Next, follow these steps to generate a certificate (for each server):ġ. Create and self-sign the root certificate: openssl req -x509 - new -nodes -key rootCA. Create the root key: openssl genrsa -des3 -out rootCA. Generating a private key and an SSL certificateįollow these steps to generate a root key and certificate:ġ. These are the paths to the SSL certificate file and private key file, respectively. func ListenAndServeTLS (certFile string, keyFile string ) errorĪs you can see from the method signature above, the only difference between this method and the ListenAndServe method is the additional certFile and keyFile arguments. The ListenAndServeTLS method is just like the ListenAndServe method, except it will start an HTTPS server. The ListenAndServe and ListenAndServeTLS methods are available on both the HTTP package and the Server structure. To start an HTTPS server, call the srv.ListenAndServeTLS(certFile, keyFile) method with some configuration, just like the srv.ListenAndServe() method. However, you can customize a server using a Server structure type. The srv.ListenAndServe() call uses Go's standard HTTP server configuration. By visiting the URL in your browser, you will be able to see a Hello World! message on the screen. In the example above, when I run the command go run server.go, it will start an HTTP server on port 8080. In this case, I need only the http.ListenAndServe function to start an HTTP server and http.HandleFunc to register a response handler for a particular endpoint.
