Nginx Configuration for HSTS Preload

Chrome, Firefox, Safari will at least check a website in the list of HSTS Preloading. Here is the right Nginx configuration for HSTS preload. We have talked about What is HTTP Strict Transport Security (HSTS) Preload List in the previously published article. Here is the working Nginx Configuration for HSTS Preload Test Passing.

Nginx Configuration for HSTS Preload : Before We Begin

This configuration is for Rackspace Cloud and we use fully default settings of Nginx. You should read the previous guide – SSL Grade Optimization Tweak For Rackspace Cloud Server. Basically, 90% has been done on the older guides. Smaller tweak is required to get the thing we want. It is, very easy.

All are discussed before. This is enough to get a A+ on SSLlabs test :

  Protocol Support 95

To generate the dhparam.pem file, you will run :

openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048
 # /etc/nginx/ssl/ is my path

1 2	openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048 # /etc/nginx/ssl/ is my path

Yes, security or grade can be increased more, but Windows and Internet Explorer will create problems :
