DIAC – Open-Source Quantum-Resistant Cryptosystem

Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

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…

We’ve just released an open-source library for solving the Maximum Independent Set (MIS) problem with neutral atom quantum computing, running on both quantum processing units (QPUs) and classical hardware, thanks to emulators. This project is the result of collaboration between Pasqal, academic researchers, and industry partners, aiming to make it practical to experiment with quantum approaches to hard combinatorial optimization tasks. The MIS problem appears in real-world scenarios like scheduling, resource allocation, and network optimization, areas where classical solvers often struggle…
