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?

OpenSpeedTest in docker through DSM Reverse Proxy - incorrect upload speeds
If you do go with NPM or Traefik, under the covers it's using certbot to request/renew your certificates through Let's Encrypt using the DNS-01 challenge, meaning you can get wildcard certs and don't have to futz around with port forwards. Again I'd think Caddy has similar functionality, I just have not used it personally. Raw NGINX you probably don't want to try out yet considering it requires manually doing the configs
- Certbot run.bat file identified as batloader trojan by windows defender. Windows defender alerted me of a trojan which appears to simply be the startup batch script for certbot. Currently running full system scan, but I suspect it to be a false positive. Any ideas?

certbot won't be missed. The code quality is pretty poor.

Let's Encrypt Certbot Not Working on FreeBSD
I am trying to migrate off of Linux and back to FreeBSD, but I hit a problem today. The Let's Encrypt Certbot is not installing. A bit surprising, given how important it is. So I thought I would notify the community Here is my bug report. https://github.com/certbot/certbot/issues/9394

Let’s Encrypt Receives the Levchin Prize for Real-World Cryptography
It goes way beyond, since Let's Encrypt influence the ecosystem a lot and the standards that are used.
If you use Let's Encrypt, you are likely using Certbot, which means that everybody uses a tool that a central authority strongly recommends to you.
I wonder how they generate the key, for example, it may be using secp256r1: https://github.com/certbot/certbot/blob/5c111d0bd1206d864d7c...
