        listen              443 ssl;
        server_name         www.example.com; # the uri
        ssl_certificate     www.example.com.crt; # the certificate (public)
        ssl_certificate_key www.example.com.key; # the private key
        ssl_protocols       TLSv1 TLSv1.1 TLSv1.2; # the ssl version
        ssl_ciphers         HIGH:!aNULL:!MD5; # the ciphers
