Categories:
Enclosed is a minimalistic web application designed for sending private and secure notes with end-to-end encryption.
🚀 Overview
Enclosed provides a simple, secure way to share sensitive notes and files online without the server having access to the content. Using client-side end-to-end encryption (AES-GCM with 256-bit keys), it ensures zero-knowledge architecture, meaning even if the server is compromised, your data remains private.
This solves the common problem of insecure note-sharing tools where servers can read your messages. It's built for privacy-conscious users, developers who prefer self-hosting, and anyone needing ephemeral, secure communication—like sharing passwords, docs, or quick notes.
Created by Corentin Thomasset as an open-source alternative to PrivateBin and similar tools, it prioritizes minimalism, top-tier security, usability across devices, and even low environmental impact (A+ Website Carbon rating).
