Let's Encrypt is a free, automated, and open certificate authority (CA) run for the public's benefit. Since its launch in 2016 Let's Encrypt has issued certificates for over 157 million fully qualified domain names and helped drive global HTTPS adoption.
As part of realizing automatic certificate management able to scale to the Internet at large Let's Encrypt helped develop a new protocol called "ACME", the Automatic Certificate Management Environment. This protocol is now published by the IETF as a standards track document, RFC 8555.
In this talk I will provide a guided tour of RFC 8555 and discuss the evolution of the protocol from its earlier drafts to the current standard. There is already a thriving ecosystem of ACME clients and more CAs are implementing servers each year. I'll close with a brief demonstration of how you can quickly and easily run your own test ACME certificate authority to experiment with the protocol.
This repository holds the full slideshow content and related sourcecode. 99% of
the repo is reveal.js. For talk content
specific to this reveal.js fork see index.html, and content/*.md.
To run/view this slideshow locally with speaker notes follow the full
reveal.js setup and run npm start in the root of the repository.
I've also added an Express wrapper (web.js) and some Heroku metadata
(Procfile) to allow the slidedeck and speaker notes application to be deployed
to heroku.
After signing up for a Heroku account and installing the heroku
CLI run the following in the
root of the repository to setup a Heroku application and deploy it.
- heroku create
- git push heroku master
I of course recommend upgrading your Dyno so you can use the Let's Encrypt integration
