We've Issued Our First IP Address Certificate

Since Let’s Encrypt started issuing certificates in 2015, people have repeatedly requested the ability to get certificates for IP addresses, an option that only a few certificate authorities have offered. Until now, they’ve had to look elsewhere, because we haven’t provided that feature. Today, we’ve issued our first certificate for an IP address, as we announced we would in January. As with other new certificate features on our engineering roadmap, we’ll now start gradually rolling out this option to more and more of our subscribers.

Ending TLS Client Authentication Certificate Support in 2026

Let’s Encrypt will no longer include the “TLS Client Authentication” Extended Key Usage (EKU) in our certificates beginning in 2026. Most users who use Let’s Encrypt to secure websites won’t be affected and won’t need to take any action. However, if you use Let’s Encrypt certificates as client certificates to authenticate to a server, this change may impact you. To minimize disruption, Let’s Encrypt will roll this change out in multiple stages, using ACME Profiles:

"... we live in a world where micro-services can be written in different languages and work together, apps can run in different OS without problems... and you're telling me you're going to shutdown a server running Linux (with some web apps running there) and install Windows there because you can't solve a problem with digital certificates??..."

I'm sorry, I had to write it here...
