- Generate certificates, run: `./cert/generate.sh`

- Start server: `node server.js`

- Open in browser: `https://127.0.0.1:8000/`

- Let's Encrypt is a free certificate authority: https://letsencrypt.org/

- Use Certbot (free tool for automatically generatinging Let’s Encrypt

certificates to enable HTTPS): https://certbot.eff.org/

- Install: `dnf -y install certbot`

- Generate certificate:

`certbot certonly --standalone -d www.domain.com -d domain.com -m your.name@domain.com --agree-tos --no-eff-email`

- Copy certificate:

`cp /etc/letsencrypt/live/domain.com/fullchain.pem ./cert/cert.pem`

- Copy private key:

`cp /etc/letsencrypt/live/domain.com/privkey.pem ./cert/key.pem`

- Or use your web server for challenge exchange:

`certbot certonly --webroot -w ./ -d domain.com -m your.name@domain.com --agree-tos --no-eff-email`
