On Wednesday, March 13, 2024, Let’s Encrypt generated 10 new Intermediate CA Key Pairs, and issued 15 new Intermediate CA Certificates containing the new public keys. These new intermediate certificates provide smaller and more efficient certificate chains to Let’s Encrypt Subscribers, enhancing the overall online experience in terms of speed, security, and accessibility. First, a bit of history. In September, 2020, Let’s Encrypt issued a new root and collection of intermediate certificates. Those certificates helped us improve the privacy and efficiency of Web security by making ECDSA end-entity certificates widely available. However, those intermediates are approaching their expiration dates, so it is time to replace them. Our new batch of intermediates are very similar to the ones we issued in 2020, with a few small changes. We’re going to go over what those changes are and why we made them. The New Certificates We created 5 new 2048-bit RSA intermediate certificates named in sequence from R10 through R14. These are issued by ISRG Root X1. You can think of them as direct replacements for our existing R3 and R4 intermediates. We also created 5 new P-384 EC
