Bon anniversaire, Let’s Encrypt!
The free-to-use nonprofit was founded in 2014 in part by the Electronic Frontier Foundation and is backed by Akamai, Google, Facebook, Mozilla and more. Three years ago Friday, it issued its first certificate.
Since then, the numbers have exploded. To date, more than 380 million certificates have been issued on 129 million unique domains. That also makes it the largest certificate issuer in the world, by far.
Now, 75 percent of all Firefox traffic is HTTPS, according to public Firefox data — in part thanks to Let’s Encrypt. That’s a massive increase from when it was founded, where only 38 percent of website page loads were served over an HTTPS encrypted connection.
“Change at that speed and scale is incredible,” a spokesperson told TechCrunch. “Let’s Encrypt isn’t solely responsible for this change, but we certainly catalyzed it.”
HTTPS is what keeps the pipes of the web secure. Every time your browser lights up in green or flashes a padlock, it’s a TLS certificate encrypting the connection between your computer and the website, ensuring nobody can intercept and steal your data or modify the website.
