Let's Encrypt is a free, automated, and open certificate authority brought to you by the nonprofit Internet Security Research Group (ISRG). Read all about our nonprofit work this year in our 2023 Annual Report.
Happy birthday to Let's Encrypt !
Huge thanks to everyone involved in making HTTPS available to everyone for free !
I worked for a company we had 300 websites, the boss wanted to buy certs. I told him about Lets Encrypt. He loved the idea it saved us a bunch of money. I suggest we donate $100 to them. Hes says "NO F-ing way!".
Crazy times. Nowadays it's weird when a website doesn't have https. Back then it was pretty much big companies only. And the price of a wildcard certificate...
I did not have the money to pay the insane amounts these greedy for-profit certificate authorities asked, so I only remember the pain of trying to setup my self-signed root certificate on my several devices/browsers, and then being unable to recover my private key because I went over the top with securing it.
And if you remember, that this whole shebang was only started, because Snowden revealed that the NSA spied on all of us, it's getting much much darker.
Oh man, I forgot about startssl until just now. I definitely had a few of those certs. If you wanted something fancy like a wildcard cert back then, you were paying $$$
A client of mine pays for an SSL cert he doesn’t even use. I’ve told him before I moved him to Let’s Encrypt because I was able to automate the renew process. He decided he needed to continue paying for the SSL cert. I told him we are not using it, but he doesn’t believe me. So he continues to pay for it.
I love it when companies are too stubborn to update their costs despite the necessity changing over the years.
My previous employment kept buying microsoft office license keys despite us already moving to 365. They probably did it out of habit when buying new computers. Needless to say I have a cardstack of license keys at home lol. Granted it’s for Office 2013 but I don’t really need the latest version for basic document processing.
Lol I instinctively freaked out when I saw the post preview assuming it was going to be a post about a major data breach or exploit of some sort relating to Let's Encrypt.
Damn! That's definitely a "I'm old" moment for me. I still remember when I first heard about the concept and I remember setting it up the first time on a self hosted project (which seemed harder back then).
I'd also argue that the fact that it's 100% automated and their software is open source makes it objectively more secure. On the issuing side, there's no room for human error, social engineering, etc.
It's sad that these arguments are still being shared. It was the same arguments years ago from people that would just assume that a free cert was inherently unsafe.
They came up with the ACME protocol, so presumably somebody could. The real barrier to entry is the cost of getting into that certificate chain of trust. I have no idea why it's so difficult and expensive.
Well, it's difficult, as it should be, because if you control a certificate in the active chain of trust of browsers, you can hack pretty much anything you want.
ZeroSSL, plus a few paid companies support ACME (I know Sectigo and GoDaddy do). Sure, the latter are paid services, but in theory you can switch to them and use the exact same setup you're currently using with Let's Encrypt, just with some config changes.
If it begins to enshitify, someone will quickly take up the helm. It's become so core now that someone like Cloudflare would just be like "We do this now."
Cloudflare sort of provides this now by being a MITM to secure your site between your server and the end user. But this requires you and your end user to trust Cloudflare.
And fwiw the ACME protocol is open so anyone can implement it. I believe even the ACME software that EFF sends out allows you to choose your server with some configuration.
HTTPS certs used to be very expensive and technically complicated, making it out of reach for most smaller orgs. Let's Encrypt brought easy mass adoption and changed encryption availability on the web for everyone.
They also made it a open protocol (the ACME protocol), so now there's a bunch of certificate providers that implement the same protocol and thus can work with the same client apps (Certbot, acme.sh, etc). I know Sectigo and GoDaddy support ACME at least. So even if you don't use Let's Encrypt, you can still benefit from their work.
For starters, you're assuming t-zero response. It'll likely be a week before people worry enough that LE isn't returning before they act. Then they have to find someone else for, possibly, the hundreds or thousands of certs they are responsible for. Set up processes with them. Hope that this new provide is able to cope with the massive, MASSIVE surge in demand without falling over themselves.
And that's assuming your company knows all its certs. That they haven't changed staff and lost knowledge, or outsourced IT (in which case they provider is likely staggering under the weight of all their clients demanding instant attention) and all that goes with that. Automation is actually bad in this situation because people tend to forget how stuff was done until it breaks. It's very likely that many certs will simply expire because they were forgotten about and the first thing some companies knows is when customers start complaining.
LetsEncrypt is genuinely brilliant, but we've all added a massive single point of failure into our systems by adopting it.
(Yeah, I've written a few disaster plans in my time. Why do you ask?)
