The goal is to provide a fully secure, zero-knowledge communication channel without requiring phone numbers, emails, or personal identification.</p> <h3> 🛡️ How it Works &amp; Security Architecture: </h3> <ul> <li> <strong>Client-Side Encryption:</strong> All encryption/decryption happens directly in the browser using Rust compiled to WebAssembly (WASM) with AES-256-GCM.</li> <li> <strong>Zero-Knowledge Server:</strong> The server acts purely as a blind relay pipe (<code>/dev/null</code> logging, no history retention). It only sees encrypted ciphertexts and never holds the private keys.</li> <li> <strong>Tor Network Native:</strong> Deployed directly on the Tor network to ensure server identity obfuscation and end-to-end anonymity.</li> </ul> <p>I’m sharing this with the community to get feedback on the cryptographic approach, architecture, and overall user experience.</p> <p>🔗 <strong>Try it on Tor (Onion Service):</strong><br> <a href="http://idcloseng647yjjnijaxhjlgn7vtthvucmqluknln7g2h76ezd72x2ad.onion/" rel="noopener noreferrer">http://idcloseng647yjjnijaxhjlgn7vtthvucmqluknln7g2h76ezd72x2ad.onion/</a></p> <p><em>(Note: You need Tor Browser to access the link above).</em></p> <p>Feedback and technical insights are highly appreciated!</p> security rust webassembly privacy
