Let's Encrypt Announces New-Certificate-Every-6-Days Offering
This letter was originally published in our 2024 Annual Report. The past year at ISRG has been a great one and I couldn’t be more proud of our staff, community, funders, and other partners that made it happen. Let’s Encrypt continues to thrive, serving more websites around the world than ever before...

Interesting. I use LetsEncrypt largely for internal services, of which I expose a handful externally, and I've been thinking of only opening the external port mapping for cert renewals. With this at 90 days, I was planning on doing this once/month or so, but maybe I'll just go script it and try doing it every 2-3 days (and only leave the external ports open for the duration of the challenge/response).
I'm guessing my use-case is pretty abnormal, but it would be super cool if they had support for this use-case. I basically just want my router to handle static routes and have everything be E2EE even on my LAN. Shortening to 6 days is cool from a security standpoint, but a bit annoying for this use-case.
You can use DNS challenge to renew your certificates without opening ports! Have a look at acme.sh for automation.
Oh, awesome! I thought that was a manual process, so I've been using the regular method.
Looks like I have a new project for this weekend. My DNS is currently hosted at Cloudflare, so this should be pretty straightforward.
Caddy with the cloudflare module makes TLS with DNS verification insanely simple
Nice! I use Caddy, so this should be a snap.
certbot has modules for most DNS providers as well.
