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.

Public CAs need their certificates to be trusted by browsers and devices. CAs that want to issue independent

A command line is a way of interacting with a computer by typing text-based commands to it and receiving text-based replies. Certbot is run from a command-line interface, usually on a Unix-like server. In order to use Certbot for most purposes, you’ll need to be able to install and run it on the command line of your web server, which is usually accessed over SSH.
