Ten years ago, securing the Web with TLS certs was thought to be unachievable. Today, Let's Encrypt has helped make it possible for 90% of Web page loads in the US to be HTTPS. Help us get that last 10% with a donation today. letsencrypt.org/donate/

ACME. SSL. PKI. The world of Web security has so many acronyms that understanding our work can be a little overwheleming. Luckily, Let's Encrypt has a glossary of the terms and acronyms that you might find when working with certificates and encryption. letsencrypt.org/docs/glossar…
