HTTPS Server

You can get free SSL/TLS certificates using Let's encrypt. If you want to have https://localhost, follow this tutorial.

To install a certificate from Let's encrypt, we mostly use certbot.

$ sudo apt update
$ sudo apt install snapd
$ sudo snap install core
$ sudo snap refresh core
$ sudo snap install --classic certbot
$ sudo ln -s /snap/bin/certbot /usr/bin/certbot

Ex: To generate one certificate for two domains, on an Apache server.

$ sudo certbot --apache --cert-name -d -d
$ sudo certbot --apache -d -d

➑️ You can add as many domains as you want with -d.

For automatic renewal:

$ sudo certbot renew --dry-run
