    I wanted to make the simplest app to introduce myself and others to quantum computing. Introducing, Schrödinger's Coin. Powered by a simple Hadamard gate[0] on IBM quantum, with this app you can directly interact with a quantum system to experience true randomness. Thoughts? Could you see any use cases for yourself of this? Or, does it inspire any other ideas of yours? Curious what others on HN think! [0] https://en.wikipedia.org/wiki/Quantum_logic_gate#Hadamard_ga...

    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…

    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 :)

    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 HN! I've created a quantum coin flip demo leveraging IBM's quantum computing tech to explore true randomness. It's a primer on into how quantum mechanics can solve classical computing's randomness limitations, crucial for cryptography and secure systems. Would love your thoughts on its application and quantum computing's future role in tech!

    I’ve developed a new public-key encryption scheme (DIAC) that uses multidimensional, high-precision complex keyspaces and a modular trapdoor function for ultra-high entropy and quantum resistance. The code, benchmarks, and research paper (PDF) are all open-source: https://osf.io/mvkcq/ Would love feedback, questions, or cryptanalysis!

    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…

    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…
