Speaker: Roland Bracewell Shoemaker Let's Encrypt is a new free and automated certificate authority, that entered closed beta in October and has already issued a large number of valid certificates. This talk will provide a short overview of how the Let's Encrypt client and server software work, and explore statistics gathered during our closed beta and launch period. Let's Encrypt is a new certificate authority that is being launched by a collaboration between EFF, Mozilla, Cisco, Akamai, IdenTrust, and a team at the University of Michigan. It will issue certificates for free, using a new automated protocol called ACME for verification of domain control and issuance. This talk will describe the features of the CA and available clients at launch; discuss ongoing feature development in both the official server and client; and share statistics on the closed beta and launch periods, as well as looking at our place within the CA ecosystem post launch.
