Profile

Hi HN, I'm Björn, the creator of ZeroNotes.I built this because I wanted a note-taking tool that offers the convenience of cloud sync but strictly ensures privacy and that anyone could read the data.The Architecture: Unlike apps that manage keys on the server, ZeroNotes is built on a strict zero-knowledge architecture.Frontend: Angular (hosted on Nginx). All crypto operations happen here.Backend: Node.js + Supabase (PostgreSQL) for storage and auth.Encryption: We use Argon2id for key derivation (from your password + salt) and AES-256-GCM for the content encryption. Keys are never sent to the server, only the ciphertext. All meta data is encrypted.Sharing: This was the hardest part. I impleme
