About ProtectedShare

Our Mission

ProtectedShare was founded with a simple goal: to make end-to-end encrypted sharing as fast and frictionless as possible. We observed that existing platforms for sending passwords, API keys, or taking private notes were either hard to use, required intrusive user logins, or were cluttered with trackers and ads.

We built a unified, free, and open-source suite that combines secure note-sharing, monospaced environment code layouts (EnvShare), and offline browser-encrypted local notepads in a single modern interface.

Zero-Knowledge Architecture

Most sharing platforms decrypt your payload on the server side to store it, or retain access keys in their backend systems. ProtectedShare utilizes the Web Crypto API to guarantee client-side **zero-knowledge** privacy:

• Your browser generates a cryptographically secure key pair.
• The data is encrypted on your local machine using AES-256-GCM.
• The key never touches the internet (stored strictly in the link's hash `#` segment or in your memory).
• Only the encrypted blob is stored on our server, which self-destructs instantly upon viewing.

Free & Open Source

We believe that security code must be transparent. The entire codebase of ProtectedShare is open source, allowing you to audit, review, or self-host your own instances.
