As we touched on in our first blog post highlighting ten years of Let’s Encrypt: Just as remarkable to us as the technical innovations behind proliferating TLS at scale is the sustained generosity we have benefited from throughout our first decade. With that sense of gratitude top of mind, we are proud to announce a contribution of $1,000,000 from Jeff Atwood. Jeff has been a longtime supporter of

In a recent conversation with a Let’s Encrypt subscriber, we asked them to guess how many people work at ISRG, the nonprofit behind Let’s Encrypt (and Prossimo and Divvi Up). Their guess was about 100; they’d overestimated by 72.5 people. We’re a pretty small team, and we get a lot done, but most of that work is entirely remote, distributed, and automated. That is a big part of what makes FOSDEM s

Every night, right around midnight (mainly UTC), a horde of zombies wakes up and clamors for … digital certificates! The zombies in question are abandoned or misconfigured Internet servers and ACME clients that have been set to request certificates from Let’s Encrypt. As our certificates last for at most 90 days, these zombie clients’ software knows that their certificates are out-of-date and need

In a ceremony held in September, Let’s Encrypt generated two new Root Certification Authorities (CAs) and six new Intermediate CAs, which we’re collectively calling the “Generation Y” hierarchy. Now we’re moving to begin issuing certificates from this new hierarchy, and to submit it to various root programs for inclusion in their trust stores. The two new roots look very similar to our existing ro

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028. This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authoriti

Nick Silverman is a Senior Infrastructure Engineer on the Edge Infrastructure team at Shopify, where he maintains the systems that provision, renew, and publish SSL certificates for millions of merchants’ custom domains. He is also a contributor to the Ruby acme-client gem. The challenge Shopify’s automated certificate management system relied on a static renewal threshold: 30 days before the end
