Nginx optimize SSL Test Grade

There is plenty articles on this topic.

It is basically limiting the accepted ciphers for the encryption and kicking out old broken encryption algorithms.

My configuration for Nginx looks something like this.

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;
add_header Strict-Transport-Security "max-age=0; includeSubdomains";

Add this to your specific host configuration in the server {} part for port 443.

For Apache I am using something like this

SSLProtocol all -SSLv2 -SSLv3
SSLCipherSuite ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-DSS-AES128-GCM-SHA2\
