ProtectedShare
Open-source zero-knowledge note sharing & private notepad.
What it does
ProtectedShare is a privacy-first utility for sharing encrypted notes, credentials, andenv files (EnvShare alternative) alongside a synchronized private notepad. All encryption happens client-side using Web Crypto (AES-256-GCM)—keys never touch the server. Features include split-channel delivery (link + password), atomic self-destructing links, and a synced notebook utilizing local SHA-256 identity hashing to keep account metadata completely anonymous. Edge-native on Cloudflare.
