Opentestudox is a privacy-first messaging system where encryption happens on your device, not the server. The server acts only as a relay — it cannot read messages or control keys. Built with client-side cryptography (WASM/libsodium) and locally generated passphrases using secure randomness. This project explores a core question: Can we reduce trust in web-based systems, or only shift it?
Hey everyone 👋
I built Opentestudox while exploring a problem that kept bothering me:
👉 In browser-based E2E apps, how do we trust the client code itself?
Most messaging apps focus on encryption, but not on how that code is delivered and whether it can be trusted.
This project experiments with:
• Running cryptography fully on the client (browser/WASM)
• Minimizing server responsibility (relay-only)
• Making trust assumptions explicit instead of hiding them
It’s still early and very much an exploration.
Would really appreciate feedback — especially from people working in security, cryptography, or distributed systems 🙌
