Hi HN, we have recently completed a research project on how to encrypt emails with post-quantum secure algorithms as well as Forward Secrecy. We'd love to hear your feedback and discuss technical issues. The paper can be found here: https://eprint.iacr.org/2021/875

Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

Hi HN, we are the developers from Tuta (formerly Tutanota), the German end-to-end encrypted email provider, and we recently released the world's first post-quantum encryption for email. We have included a full technical write-up of the cryptography involved in these changes and we have released it for open public review. This document specifies TutaCrypt, a protocol designed for hybrid email encryption in Tuta Mail. The protocol combines a classical Elliptic-Curve-Diffie-Hellman key exchange with a post-quantum KEM. The goal is to replace the usage of RSA in Tuta Mail. In the remainder of…

This is an educational reference implementation showing how to build reasonably secure, standards-compliant authentication from first principles on Cloudflare Workers. Stack: Hono, Turso (libSQL), PBKDF2-SHA384 + normalization + common-password checks, JWT access + refresh tokens with revocation support, HTTP-only SameSite cookies, device tracking. It's deliberately minimal — no OAuth, no passkeys, no magic links, no rate limiting — because the goal is clarity and auditability. I wrote it mainly to deeply understand edge-runtime auth constraints and to have a clean Apache-2.0 example that…

This project has been kicking around in my head since I first heard about the webauthn PRF extension in early 2024. I've slowly chipped away at it since, and finally got things to a shareable state over the summer thanks to a very fun parental leave. Headed back to work tomorrow, so I figure there's no time like the present. tldr: A client-held encryption key derived during passkey authentication encrypts all sensitive user data prior to persistence so that only the user is able to decrypt and reuse that data on their device. This allows short-lived, privacy-preserving age proofs to be…

Hi HN, I'm Dan Draper, founder of CipherStash. We've spent 5 years building per-value searchable encryption tech. We realized that encryption like this is incredibly powerful but the engineering required is generally not worth the effort. So we built a platform and opensource SDK to take the cry out of cryptography :) CipherStash Stack is: * A searchable encryption SDK for TS and Postgres * Fast, key management with Zerokms (backed by HSM) * A transparent SQL proxy * Auth library and OIDC federation service * Skills for data security Integrations include Prisma Next, Drizzle, Auth0, Clerk…

hey folks! My book Real-World Cryptography was just released and is now shipping. I've been working on this thing for the last two years and a half, and the goal was to give a good overview of everything that can be classified as "real-world" about crypto. You'll find all the basics in the first half of the book, and the second half contains chapters on TLS, noise, PAKEs, post-quantum cryptography, zero-knowledge proofs, MPC, cryptocurrencies, FHE, etc. So it's a good pick if you're learning, but also if you've been in the field for a while and want an intro to some subfield you're…
