Nginx SSL example

This post dates from 2014 and I would recommend to use the Mozilla SSL Configuration Generator to get a more accurate configuration:

This post is more of a reminder for myself but it might help others, it shows a example of how to setup a good vhost with SSL support that gives a A+ rating with a (100/95/100/100) score.

Example of my website:

Nginx SSL example.

server {
  listen 80;
  add_header X-Frame-Options DENY;
  add_header X-Content-Type-Options nosniff;
  return 301$request_uri;

server {
  listen 443 ssl default_server;
  listen [::]:443 ssl default_server ipv6only=on;

  root /srv/nginx/;
  index index.php;

  access_log /var/log/nginx/ main;
  error_log /var/log/nginx/;

if ($http_user_agent ~ "Windows 95|Windows 98||xpymep|TurnitinBot|sindice|Purebot|libwww-perl") {
  return 403;

  ssl_certificate /etc/nginx/ssl/;
  ssl_certificate_key /etc/ssl/certs/;
  ssl_dhparam /etc/nginx/ssl/dhparams.pem;
  ssl_session_cache builtin:1000 shared:SSL:2m;
  ssl_session_timeout 5m;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;


  ssl_stapling on;
  ssl_stapling_verify on;
  resolver valid=300s;
  resolver_timeout 5s;
  ssl_trusted_certificate /etc/ssl/certs/;

  add_header Strict-Transport-Security "max-age=31536000;";
  add_header X-Frame-Options DENY;
  add_header Public-Key-Pins "pin-sha256=\"zco8Bhue8GQPxzzGd9unFQteH9JAk4VUxsofgGUkb7k=\"; max-age=172800;";

location = /favicon.ico {
  alias /srv/nginx/;

location ~ /\.ht {
  deny all;

location / {

To get your “Public key pin” you can use the command:

$ openssl rsa -in -outform der -pubout | openssl dgst -sha256 -binary | openssl enc -base64

Of course use your own key file.

If anyone has a better way of a more secure way feel free to show me I would like to see more examples or learn more about it.
