05 Apr How to Add a Free SSL Certificate to Your Raspberry Pi with Let’s Encrypt

Want to make your Raspberry Pi web server more secure? Adding an SSL certificate encrypts your connections, protecting your data from prying eyes. The best part? You can do it for free using Let’s Encrypt, a trusted certificate authority that provides easy-to-install SSL certificates.

In this guide, we’ll walk through the steps to secure your Raspberry Pi server with HTTPS, ensuring safe and encrypted communication.

Step 1

Let’s update our Raspberry Pi

sudo apt update
sudo apt upgrade

Step 2

Let’s install the certbot app compatible with Apache. If you have any other web server, you might have to find the correct installation for yours:

sudo apt install python3-certbot-apache

Step 3

In your router configuration, make sure you are forwarding port 443 to your Raspberry Pi. Now, type the following:

sudo certbot --apache

It will ask you to add your email, and your domain name. This is the external domain name -hostname- that will be pointing to your Raspberry Pi. You can get a Dynamic hostname here https://www.noip.com?fpr=n3by1.

That’s it. Now you can access your Raspberry Pi using https instead of http.
