Open-source zero-knowledge note sharing & private notepad.

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.

@kunal_builds The split-channel verification approach is clever—sending the link and password separately is a practical security pattern that actually gets used. One question: for the synchronized notepad, how do you handle conflict resolution if someone edits the same note across multiple devices simultaneously, or does the last-write-win model work for your use case?
@saulfleischman Thank you for the respsone. For now, it's the last-write win but after your comment, I am thinking of working on a solution wherein the user can do a Git-like version control for their notes. It will be a messy process, since the server since the server cannot read or decrypt the plaintext notes, meaning all branch tracking, diffing, and conflict-resolution logic must be handled entirely on the client-side. Will make it work somehow.
