Top comment
Hey Product Hunt! 👋 I’m thrilled to introduce LockNotes, the latest release out of Webrizen. We wanted to build a one-time secret app that didn't just function as a basic utility, but actually pushed the boundaries of both web cryptography and frontend design. The Architecture (Zero-Knowledge): Most anonymous messaging apps require you to trust the server. We removed trust from the equation. When you type a note, it is encrypted locally in your browser using AES-GCM 256-bit encryption. The decryption key is attached to your shareable URL as a hash fragment (#key). Because browsers never send hash fragments to the server, it is mathematically impossible for us to read your payload. When the recipient opens the link, an atomic PostgreSQL transaction instantly nukes the row before decrypting it locally. The Design Language: We wanted the user experience to be unforgettable. The creation page features a custom WebGL fragment shader animated with GSAP, designed to evoke the lush, ethereal skies and volumetric lighting of modern Japanese animation films. However, the moment the recipient opens the link to read the secret, the UI instantly snaps into a strict, high-contrast, DX-inspired technical grid to reflect the secure, raw nature of the decrypted payload. Stack: Next.js, Supabase (with custom RPCs), GSAP/Framer Motion, and Transformers.js (for on-device AI toxicity filtering to prevent abuse). I would love to hear your thoughts on the zero-knowledge implementation, the UI transitions, or the tech stack. I’ll be hanging out in the comments all day to answer your questions!
