Auto TLS

This recipe demonstrates how to obtain TLS certificates for a domain automatically from Let's Encrypt. Echo#StartAutoTLS accepts an address which should listen on port 443.

Browse to https://<DOMAIN>. If everything goes fine, you should see a welcome message with TLS enabled on the website.

tip

• For added security you should specify host policy in auto TLS manager
• Cache certificates to avoid issues with rate limits (https://letsencrypt.org/docs/rate-limits)
• To redirect HTTP traffic to HTTPS, you can use redirect middleware
