How to Build Email Server with Exim on Alma Linux 9
Next, we will install acme.sh, a command-line tool for managing SSL/TLS certificates. I prefer acme.sh over certbot, as it does not depend on the OS version. For more details about acme.sh, check its GitHub repo here.

Dehydrated: Letsencrypt/acme client implemented as a shell-script
A very relevant question. Acme.sh, a similar shell script ACME client, had a remote code execution problem last year.

Ask HN: What is your experience with ZeroSSL?
As a result, any certificates issued (or renewed) after Feb 8th will not work on older Android devices (< 7.1.1), unless the ACME client has been configure to request an alternate certificate chain. The "alternate chain" workaround will also stop working on June 6th.
I need to support these older Android devices so I am looking for alternatives. I have seen ZeroSSL mentioned a few times; it is also the default CA for acme.sh (the ACME client I am using nowadays) [2]. They have a number of paid plans but ACME certificates are free [3].
I'll be testing this over the next few days, but I would also like to ask if people here have experience with ZeroSSL (good or bad :-). Any feedback would be helpful.

Why Certificate Lifecycle Automation Matters
Huh, the environment variable thing was specifically aimed at acme.sh which rather arbitrarily changed the config value from ACMEDNS_UPDATE_URL to ACMEDNS_BASE_URL, never acknowledged this in a changelog and then silently failed after an automatic upgrade as recommended by the default install:
https://github.com/acmesh-official/acme.sh/commit/2ce145f359...
It's also cleared out my .account.conf files when run on the suggested cron.
I've started using updown which also monitors my TLS certs simply because I no longer trust the process to work as documented.

The Bureau of Meteorology website does not support connections via HTTPS
It depends on your provider though. I can tell from experience that with OVH and their API, it's been easy to set up the automatic renewal via DNS verification. Apparently, the official client has support for the DNS API of 159 providers: https://github.com/acmesh-official/acme.sh/wiki/dnsapi

I made a tool for automatically updating the current and next (rollover) TLSA DNS records with acme.sh and the Cloudflare API
For the few people here that happen to run a self-hosted email server with acme.sh for TLS key/cert generation and Cloudflare for DNS management, I have made a tool that i personally use to get a perfect 100% score on Internet.nl's email test.

How to get LetsEncrypt certs from PfSense/ACME to other machines? (automated??)
All of this is to say it's a decent amount of work to save the hassle of deploying certbot or acme.sh on the remote machines, pick your poison.

This is Fine
People wonder why I like using the shell-based ACME client like dehydrated (or acme.sh):
* https://packages.debian.org/search?keywords=dehydrated
* https://github.com/acmesh-official/acme.sh
Versus the official client certbot:
* https://packages.debian.org/search?keywords=python3-certbot
A kludgy as very long shell scripts are (thought to be), I have a better chance of being able to go through all the code and understand it than a dozen(+) Python libraries.

Where to get free SSL certificates?
So today I figured out how to install acme.sh to my hosted server space for my websites, and used acme to issue an SSL certificate and install it for a domain. It uses LetsEncrypt, and ZeroSSL for the default Certificate Authority (CA). Then I notice that ZeroSSL only allows a free 90 day certificate, and only 3 of those before you have to pay. Is there any way to generate actual free SSL certificates that do not expire for a year or more and that can be renewed free? I have heard that most hosting plans now provide free SSL certs, so is my hosting company just providing cheap hosting but making money on the backend by charging for SSL certs?

Seeking Guidance: SSL Certification for a Local Server in Windows 2019 Data Center Environment
Option 2+: If your public DNS is hosted by a provider that has Win-ACME or Certify the Web support, use Let's Encrypt and automate the whole thing.

How will you handle 90 day SSL expiration?
For Exchange and Remote Desktop Service we are using Certify The Web with Lets Encrypt. Works really well.

Ask HN: What are your “scratch own itch” projects?
It's worth doing! A few projects I've done:
I once needed a database of EV charging locations, but at the time(2011) there were no open databases, so I built https://openchargemap.org, that now serves millions of API queries per month for other apps and services
For another project, I recently wanted to control my guitar amp (a Positive Grid Spark) from my computer instead of using a mobile app, so I built https://soundshed.com which is both a bluetooth web app and an electron app you can install. It now has a few thousand users :)
And finally, another time I had some SSL certificates I needed to manage for another project (for the above mentioned https://openchargemap.org), so I built a GUI to manage and renew certificates on Windows. It's now a commercial app with hundreds of thousands of users and it's my full time job: https://certifytheweb.com
So yeah, worth doing!
What are some alternatives?
letsencrypt - Certbot is EFF's tool to obtain certs from Let's Encrypt and (optionally) auto-enable HTTPS on your server. It can also act as a client for any other CA that uses the ACME protocol.
win-acme - A simple ACME client for Windows (for use with Let's Encrypt et al.)
Nginx Proxy Manager - Docker container for managing Nginx proxy hosts with a simple, powerful interface
dehydrated - letsencrypt/acme client implemented as a shell-script – just add water
Posh-ACME - PowerShell module and ACME client to create certificates from Let's Encrypt (or other ACME CA)
