Enclosed on Ubuntu 24.04 LTS

Overview

Enclosed is an open source, minimalist tool for sharing secrets. You write a note or attach a file, and everything is encrypted right there in your browser with AES 256 before anything leaves the page, so the server that stores it only ever holds unreadable ciphertext and never sees your content or the key. Enclosed hands you a single link to pass to the person you are sharing with; the key that unlocks the note lives in the link itself, in the part after the hash that browsers keep local and never send to a server. The recipient opens the link and reads the note in their own browser, with no account and nothing to install. Before you send, you can lock a note behind an extra password, limit it to a single view so it destroys itself once read, and set it to expire after an hour, a day, a week or a month, which makes it a clean way to hand someone a password, an API token or a private message without leaving it sitting in chat or email.

Common uses

• Send a password, API key or private message as a one time, self destructing link
• Give teams a self hosted, zero knowledge way to share secrets without third party services
• Hand a contractor or client a credential that expires automatically after a set time
