Improving SSL Configuration

• Documentation:
  • NGINX ssl module
  • Mozilla’s Server Side TLS Documentation
• Add session caching so that fewer SSL handshakes need to be made.
• The initial handshake is the most taxing part of the process, and if we can avoid repeating it then we’ll improve our overall performance.

  $ vim /etc/nginx/conf.d/default.conf
  

ssl_certificate /etc/nginx/ssl/public.pem;
