debian ubuntu certificate security tls ssl certbot cloudflare certbot letsencrypt
Have a server that’s offering services that need to be secured with TLS but you can’t install a web server, can’t open port 80 or have something using that port you can’t shutdown? How do you get free Let’s Encrypt certificates? If you’re using Cloudflare for your DNS we can use certbot and automate the whole thing including renewals! If you’re using another DNS server provider, the basic process still works too.
