Document SSL/HTTPS best practice

[bbodenmiller]

Would like to see the recommended way to setup Piwik with HTTPS.

I`ve just added an ssl.conf as include in nginx.conf my ssl.conf looks like this (via letsencrypt ssl service on Ubuntu):

replace <domain> with your domain as letsencrypt generated

ssl_certificate /etc/letsencrypt/live/<domain>/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/<domain>/privkey.pem;
ssl_session_timeout 1d;

# Diffie-Hellman parameter for DHE ciphersuites, recommended 2048 bits
# if needed - may be generated with:
# openssl dhparam -out /etc/nginx/dhparam.pem 4096
# ssl_dhparam /etc/nginx/dhparam.pem;

# intermediate configuration. tweak to your needs.
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';
ssl_prefer_server_ciphers on;

# HSTS (ngx_http_headers_module is required) (15768000 seconds = 6 months)
# uncomment if HSTS needed
# add_header Strict-Transport-Security max-age=15768000;

# OCSP Stapling ---

ssl_stapling on;
ssl_stapling_verify on;

Thanks for the report, the new version of the config includes the modern mozilla profile.
