Sub Rosa

What it does

Sub Rosa is a zero-knowledge secret sharer. We physically cannot read your messages. Most tools generate keys on the server. We don't. Your browser encrypts data locally using the Web Crypto API. The key lives in the URL hash (#) and never touches our logs or database. We only store the encrypted blob, which is burned instantly after reading. 100% Open Source. No ads. No trackers. Just privacy.

  Retriever – Securely share secrets over the internet2024 · retriever.corgea.io · ▲193

  Retriever (https://retriever.corgea.io/), an open-source research project to help users receive secrets and sensitive information without needing a server in the middle. It works by using Public-key cryptography to coordinate the message sharing between the two devices. Read more on why we built it here: https://retriever.corgea.io/why.html

  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…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
