   StealthDrop – Anonymous crypto airdrops using zero-knowledge proofs▲105

   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…

   An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf▲66

   This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

    Ariadne – A Rust implementation of aperiodic cryptography▲40

    Hello HN, we're CipherNomad, the research initiative behind this project. The Ariadne Protocol is our exploration of a different cryptographic model. The work began with an observation of primitives like the Lion transform, which use a static, hardcoded sequence of operations. This led us to ask: What if the cryptographic "program" wasn't a constant, but a dynamic, history-dependent variable? Our first step was a "Cryptographic Virtual Machine" that took an explicit list of operations (a "Path"). This worked, but required sharing the Path object—an explicit dependency that needed to be…

    TideCloak – Decentralized IAM for security and user sovereignty▲54

    Hey HN! After 6 years of R&D, our small team is excited to share our project TideCloak - an IAM designed to help developers move fast without worrying about catastrophic breaches or overpowered admins with keys to the kingdom. Traditional IAMs rely on centralized authority - admins, root certificates, and decryption keys - which create glaring vulnerabilities in a breach. To address this, we’ve integrated Keycloak (Red Hat’s IAM) with a decentralized key architecture powered by our (academically validated) Ineffable Cryptography. Here’s the idea: keys are split across a decentralized network…

    Anonymous age verification with passkey-powered encryption▲45

    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…

    CipherStash Stack – Data Level Access Control in TS/JS▲17

    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…
