acme-tiny VS getssl

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 :-)

A 'competitor' to this would be GetSSL which is a pure-shell ACME client (plus OpenSSL and cURL) and can be executed on one host, but send verification tokens to remote systems (where you may not have cron access):

> Get certificates for remote servers - The tokens used to provide validation of domain ownership, and the certificates themselves can be automatically copied to remote servers (via ssh, sftp or ftp for tokens). The script doesn't need to run on the server itself. This can be useful if you don't have access to run such scripts on the server itself, as it's a shared server for example.

I first got by with self signed certificates, but with all the major browsers warning they'll stop supporting those eventually I finally bit the bullet last month and installed getssl to automatically update all my certificates once a month.

because I didn't want to install another package manager (snapd) on my Ubuntu 18.04 server I checked the ACME Client Implementations page and decided to try getssl, a nice little shell script that does everything I need and then some.

I just have a dedicated container that runs getssl everyday. Anything that has a web interface (Or anything that requires TLS) gets it's own conf file that gets added to the daily check. Each conf file tells getssl how to load the certificate for its particular service.

I have been using https://github.com/srvrco/getssl for years on my raspberry pi. It's a much simpler Bash script that doesn't break after every update.

i have a problem where after installing getssl (https://github.com/srvrco/getssl) to /root/.getssl i populated it's contents with bunch of SSL files using Dockerfile's COPY command. And now no matter what i do they keep reappearing.

Another shell-based ACME client I like is dehyradted. But for sending certs to remote systems from one central area, perhaps the shell-based GetSSL:

> Obtain SSL certificates from the letsencrypt.org ACME server. Suitable for automating the process on remote servers.

In general, what you may want to do is configure Ansible/Puppet/etc, and have your ACME client drop the new cert in a particular area and have your configuration management system push things out from there.
