acme-tiny VS dehydrated

Going to throw another hat into the ring here: I use acme-tiny [1], which is a single file ACME client written in Python in under 200 lines. The idea behind it is that you can fully read and understand everything it does without spending too much time on it. I really like this approach, so I went ahead and started using it, and have been for a few years now.

Let’s Encrypt with ACME-Tiny

Recommendation from me as well. Have been using this script for multiple years now without a single issue. The minimal code is awesome for avoiding unnecessary external dependencies and complexity.

Be sure to use the latest version from https://github.com/diafygi/acme-tiny though :-)

I've had a lot of success with https://github.com/dehydrated-io/dehydrated . It exposes the different parts of the process (deploy challenge to DNS, deploy cert to filesystem, etc) as hooks, so it's pretty easy to integrate with anything and however you want, if you don't mind writing a bit of bash. There's a few scripts out there that use Cloudflare that you can use as well.

Depend on host's capability... - lego - dehydrated - caddy - in case it already works as a web server, it will automatically issue and renew certs

Take a look at this great project : https://github.com/dehydrated-io/dehydrated/wiki : many dns providers are documented.

> Oh, and that 500-line shell script probably ends up being a 5000-line Python monster anyway.

The dehydrated ACME client is 2400 lines of bash/zsh:

* https://github.com/dehydrated-io/dehydrated

And its external dependencies are OpenSSL and cURL. The acme.sh shell ACME client is 8000 lines of shell:

* https://github.com/acmesh-official/acme.sh

The official Let's Encrypt client is written in Python, and the core 'executable' is much longer, and in addition it pulls in a boatload of dependencies:

* https://packages.debian.org/bullseye/python3-certbot

Dehydrated.io, damn few dependencies.

You're welcome.

I prefer dehydrated as an ACME client because it's written in bash and the only dependencies are sed, awk, grep, and openssl. This will also leave you free to customize your nginx config as necessary without having to try to cram your needs into a generator that doesn't account for what you're trying to do. It seems odd to me that the generator would create the intermediary file (as per your quoted output above), but then not put that in the nginx config.

This project has helped us immensely with cert renewals - https://github.com/dehydrated-io/dehydrated

If you don't wanna use a CDN (or if you're also worried about the backend traffic between the CDN and your server) then you can use certbot or dehydrated or something similar to automate the provisioning of letsenscrypt.org certificates on your server (or just ensure you're using a host that does this for you).
