We’re excited that support for getting and managing TLS certificates via the ACME protocol is coming to the Apache HTTP Server Project (httpd). ACME is the protocol used by Let’s Encrypt, and hopefully other Certificate Authorities in the future. We anticipate this feature will significantly aid the adoption of HTTPS for new and existing websites. We created Let’s Encrypt in order to make getting

Reports will be published three months after the period covered in order to allow us time to research all requests and orders received during the period. Download Legal Transparency Repo

Let’s Encrypt had a great year in 2018. We’re now serving more than 150 million websites while maintaining a stellar security and compliance track record. Most importantly though, the Web went from 67% encrypted page loads to 77% in 2018, according to statistics from Mozilla. This is an incredible rate of change! We’d like to thank all of the people and organizations who worked hard to create a mo

Our first full year as a live CA was an exciting one. I’m incredibly proud of what our team and community accomplished during 2016. I’d like to share some thoughts about how we’ve changed, what we’ve accomplished, and what we’ve learned. At the start of 2016, Let’s Encrypt certificates had been available to the public for less than a month and we were supporting approximately 240,000 active (unexp

The Let’s Encrypt root key (ISRG Root X1) will be trusted by default in Firefox 50, which is scheduled to ship in Q4 2016. Acceptance into the Mozilla root program is a major milestone as we aim to rely on our own root for trust and have greater independence as a certificate authority (CA). Public CAs need their certificates to be trusted by browsers and devices. CAs that want to issue independent

Today we kicked off our first crowdfunding campaign with the goal of raising enough funds to cover about one month of our operations - $200,000. That amount covers the operational and engineering staff, the hardware and the software, and general operating expenses needed to securely and reliably issue and manage many millions of certificates. We decided to run a crowdfunding campaign for a couple

Let’s Encrypt had a great year in 2017.

Today we’d like to explain what it costs to run Let’s Encrypt. We’re doing this because we strive to be a transparent organization, we want people to have some context for their contributions to the project, and because it’s interesting. Let’s Encrypt will require about $2.9M USD to operate in 2017. We believe this is an incredible value for a secure and reliable service that is capable of issuing
