A Note from our Executive Director
letsencrypt.org
This letter was originally published in our 2024 Annual Report. The past year at ISRG has been a great one and I couldn’t be more proud of our staff, community, funders, and other partners that made it happen. Let’s Encrypt continues to thrive, serving more websites around the world than ever before with excellent security and stability. Our understanding of what it will take to make more privacy-preserving metrics more mainstream via our Divvi Up project is evolving in important ways.

      It would be six days at max, assuming they managed to steal the certificate immediately after it was issued, otherwise it’s gonna be even less.

      Having the certificate doesn’t automatically mean you can change the site, if you have control of the site hosting you likely wouldn’t need to steal the cert anyway.

      Stealing the certificate would allow you to run a man in the middle type attack but that’s inevitably going to be very limited in scope. The shorter time limit on the cert reduces that scope even further, which is great.

      Since most Let’s Encrypt certs will have an automated renewal process this doesn’t even really change the overhead of setup so I think this move makes a lot of sense.

      There are other things certificates can be used for as well of course but I’m just going off your example.
