SSL/TLS Encryption

An important part of any web application's security strategy is valid SSL/TLS encryption. Nanobox allows you quickly and easily encrypt your application with an automated Let's Encrypt integration as well as the ability to create and/or import third-party SSL/TLS certificates.

Adding SSL/TLS Encryption

When adding SSL/TLS certificates to your application, you have a few options. You can either use Let's Encrypt, create a private key and certificate signing request (CSR) to key a new third-party certificate, or import an already existing and previously-keyed third-party certificate.

The Adding SSL/TLS doc walks through each option for creating and installing SSL/TLS certificates in your application.

Forcing HTTPS

Forcing SSL/TLS encryption happens on the application level, typically within your app's web server. All app's deployed with Nanobox sit behind your app's router. As requests pass through the router, Nanobox appends the X-Forward-Proto header with the origin protocol of the incoming request (More information here.

Below are examples of forcing HTTPS using the X-Forward-Proto header with popular web servers.


if ($http_x_forwarded_proto != 'https') {
    rewrite ^ https://$host$request_uri? permanent;


RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
