All notes are end-to-end encrypted, ensuring that the server and storage have zero knowledge of the content. Users can set a password, define an expiration period (TTL), and choose to have the note self-destruct after being read. A live instance is available at [enclosed.cc](https://enclosed.cc). [](https://enclosed.cc) ## Features - **End-to-End Encryption**: Your notes are encrypted on the client side, using AES-GCM with a 256-bit key derived using PBKDF2. - **File Attachments**: Share files securely with your notes. - **Zero Knowledge**: The server does not have access to the content of the notes or files. - **Configurable Security Options**: Set a password, expiration time, and choose self-destruction after the note is read. - **Minimalistic UI**: Simple and intuitive user interface for quick note sharing. - **i18n Support**: Available in multiple languages. - **Authentication**: Optional email/password authentication to create notes. - **Dark Mode**: A dark theme for late-night note sharing. - **Responsive Design**: Works on all devices, from desktops to mobile phones. - **Open Source**: The source code is available under the Apache 2.0 License. - **Self-Hostable**: Run your instance of Enclosed for private note sharing. - **CLI**: A command-line interface for creating notes from the terminal. - **Very low environmental impact**: the app and the docs is rated A+ on websitecarbon.com (see [here](https://www.websitecarbon.com/website/enclosed-cc/) and [here](https://www.websitecarbon.com/website/docs-enclosed-cc/)). ## Self host ### Try it with Docker You can quickly run the application using Docker. ```bash docker run -d --name enclosed --restart unless-stopped -p 8787:8787 corentinth/enclosed ``` ### To go further Please refer to the [self-hosting documentation](https://docs.enclosed.cc/self-hosting/docker) for more information on how to configure and run the application. For example: - [Setup persistent storage](https://docs.enclosed.cc/self-hosting/docker#docker-with-volume-persistence) - [Use rootless image](https://docs.enclosed.cc/self-hosting/docker#rootless-and-non-rootless-docker-images) - [Use Docker Compose](https://docs.enclosed.cc/self-hosting/docker-compose) ### Configuration You can refer to the [configuration documentation](https://docs.enclosed.cc/self-hosting/configuration) for more information on how to configure the application. ## How It Works 1. **Note Creation**: A user creates a note with some content and optionally sets a password. 2. **Key Generation**: A **base key** is generated on the client side to ensure encryption, even if no password is set. 3. **Master Key Derivation**: A **master key** is derived from the base key and the optional password using **PBKDF2 with SHA-256**. 4. **Note Encryption**: The note is encrypted using the master key with **AES-GCM** encryption. 5. **Sending to Server**: The encrypted note is sent to the server along with some metadata (ttl, is the note password-protected, should it self-destruct after reading). 6. **Storage and ID Assignment**: The server stores the encrypted note and provides an **ID** for it. 7. **Link Generation**: A **link** is generated that includes the note ID and the base key (included as a URL hash fragment to maximize security since hashes are not sent to the server). 8. **Link Sharing**: The link is shared with the intended recipient. 9. **Note Retrieval**: The recipient opens the link, and the app fetches the encrypted note and metadata from the server using the note ID. 10. **Key Extraction**: The base key is extracted from the URL hash fragment. 11. **Password Prompt (If Applicable)**: If the note is password-protected, the recipient is prompted to enter the password. 12. **Master Key Derivation**: The master key is derived from the base key and the entered password using **PBKDF2 with SHA-256**. 13. **Note Decryption**: The note is decrypted using the master key with **AES-GCM** and can now be read by the recipient. This ensures that the note remains securely encrypted during transmission and storage, with decryption only possible by those with the correct link and (if applicable) password. ## CLI The Enclosed CLI allows you to create notes from the terminal. You can install it globally using npm, yarn, or pnpm. ### Installation ```bash # with npm npm install -g @enclosed/cli # with yarn yarn global add @enclosed/cli # with pnpm pnpm add -g @enclosed/cli ``` ### Create a note ```bash # Basic usage enclosed create "Hello, World!" # Using stdin cat file.txt | enclosed create # With full options enclosed create --deleteAfterReading --password "password" --ttl 3600 "Hello, World!" ``` ### View a note ```bash # The password will be prompted if the note is password-protected enclosed view <note-url> # Or you can provide the password directly enclosed view --password "password" <note-url> ``` ### Configure the enclosed instance to use ```bash # By default, the CLI uses the public instance at enclosed.cc enclosed config set instance-url https://enclosed.cc ``` ## Project Structure This project is organized as a monorepo using `pnpm` workspaces.
