Simple Secure Server

Prerequisites:

• Your server must be reachable through the provided domain name, this is how LetsEncrypt verifies domain ownership and grants your server a trusted certificate

With Default Values:

ss, err := sslmgr.NewSecureServer(handler, "yourhostname.com")
if err != nil {
	log.Fatal(err)
}
ss.ListenAndServe()

Note: This option uses the file system as the certificate cache. If your use case does not have a persistent file system, you should provide a value for CertCache in the ServerConfig as shown below.

With Optional Values:

(Using the certcache library to define a cache)

ss, err := sslmgr.NewServer(sslmgr.ServerConfig{
	Hostnames: []string{os.Getenv("CN_FOR_CERTIFICATE")},
	HTTPPort:  ":80",
	HTTPSPort: ":443",
	Handler:   h,
	ServeSSLFunc: func() bool {
		return strings.ToLower(os.Getenv("PROD")) == "true"
	},
	CertCache: certcache.NewLayered(
		certcache.NewLogger(),
		autocert.DirCache("."),
	),
	ReadTimeout:         5 * time.Second,
	WriteTimeout:        5 * time.Second,
	IdleTimeout:         25 * time.Second,
	GracefulnessTimeout: 5 * time.Second,
	GracefulShutdownErrHandler: func(e error) {
		log.Fatal(e)
	},
})
if err != nil {
	log.Fatal(err)
}

ss.ListenAndServe()
