A look at the latest post-quantum signature standardization candidates
NIST has standardized four post-quantum signature schemes so far, and they’re not done yet: there are fourteen new candidates in the running for standardization. In this blog post we take measure of them and discover why we ended up with so many PQ signatures.

A Post-Quantum Future for Let's Encrypt
Let’s Encrypt is committed to a post-quantum-safe Web PKI. The path we’re planning to take is Merkle Tree Certificates (“MTCs”), a new approach that adds post-quantum authentication to the web without sacrificing the speed and reliability that have made TLS universal. This post is about these plans and why we believe MTCs are worth pursuing as a key to a post-quantum future. An increasingly urgent problem For much of the last several years, the conversation about post-quantum cryptography has been a conversation about encryption. The reasoning was straightforward: an attacker who records encrypted traffic today might be able to decrypt it years from now once quantum computers can break the underlying math. Authentication, the part of TLS that indicates a server is who it says it is, has been a less urgent problem. A quantum computer needs to forge a signature in real time, not retroactively, so threats to authentication hinge on the existence of a cryptographically relevant quantum computer (CRQC).
Unlocking Quantum-Encrypted Group Chats for ATProto on XMTP
Developers building with ATProto (the protocol powering Bluesky) have been asking how they can use XMTP to power messaging between users in their apps. It’s possible today to add secure messaging to any Bluesky app, and to add Bluesky identity to any messenger built on XMTP. 0:00 /0:
