Enclosed review: an open-source, end-to-end encrypted app for sending private, self-destructing notes and files. See features, self-hosting, and pricing.
Enclosed is a free, open-source web app for sending private, end-to-end encrypted notes and files that self-destruct after being read or after a set expiration time. It was built by French engineer Corentin Thomasset and launched publicly on Product Hunt in October 2024.
The tool is designed for sharing sensitive one-time information such as passwords or API keys through a link rather than plaintext email or chat, with encryption happening entirely in the sender's browser so the server never has access to the content.
Notes are encrypted client-side with AES-GCM using a 256-bit key derived via PBKDF2, giving Enclosed a genuine zero-knowledge architecture where even the server operator cannot read note contents.
Senders can optionally password-protect a note, set an expiration time, attach files, or trigger self-destruction immediately after the first read, and a command-line interface lets developers create notes directly from a terminal.
Enclosed is entirely free to use at the public enclosed.cc instance, with no paid tiers or subscription plans.
The source code is released under the Apache License 2.0 and published on GitHub with an official Docker image, so anyone can self-host their own private instance at the cost of their own infrastructure.
Yes. Enclosed is completely free at the public enclosed.cc instance, and self-hosting the open-source Docker image is also free aside from your own infrastructure costs.
Enclosed encrypts notes in the sender's browser using AES-GCM with a 256-bit key derived via PBKDF2 before sending anything to the server, so the server never has access to the plaintext content or decryption key.
Yes. Enclosed is open source under the Apache License 2.0 and publishes an official Docker image (corentinth/enclosed) for self-hosting.

Yes. Enclosed includes a command-line interface so developers can create and share encrypted notes directly from a terminal.
Similar self-destructing, encrypted note-sharing tools include PrivNote, Yopass, and OneTimeSecret.
