## What Jamie wrote

Let's Encrypt may be the most important project on the web in the last decade. This recent milestone is mind blowing.

> Just at the end of September 2025, we issued more than **ten million certificates in a day** for the first time.

This might seem like technical gibberish but this is what makes your web connection secure. Before Let's Encrypt this stuff was so hard, expensive, and effectively off limits to non-commercial users. 

Now we have an ever more secure web, open to all, and funded by a non-profit. I love this project and what it has done for the world. I've been a proud supporter since they launched. If you use the web, you should [send them a few bucks](https://letsencrypt.org/donate/). Really. 🔐
