openssl dhparam -out www_safematix_com_dhparam.pem 4096
ssl on;

ssl_certificate /etc/nginx/ssl/safematix/www.safematix.com.crt;
ssl_certificate_key /etc/nginx/ssl/safematix/www.safematix.com.key;

ssl_dhparam /etc/nginx/ssl/safematix/www.safematix.com-dhparam.pem;
ssl_trusted_certificate /etc/nginx/ssl/ca.pem;

ssl_session_timeout 5m;
ssl_session_cache shared:SSL:10m;

ssl_stapling on;
ssl_stapling_verify on;
resolver 8.8.4.4 8.8.8.8 valid=300s;
resolver_timeout 10s;

add_header Strict-Transport-Security max-age=63072000;
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;

ssl_prefer_server_ciphers on;

ssl_ciphers 'AES256+EECDH:AES256+EDH:!aNULL';
add_header Strict-Transport-Security max-age=15768000; # six months

add_header Strict-Transport-Security "max-age=15768000; includeSubDomains";
