Enclosed
Minimal app for sharing end-to-end encrypted notes and files
Enclosed is a minimalistic web application for sending private notes and file attachments using end-to-end encryption. Notes are encrypted in the browser so the server stores only ciphertext and cannot read the content.
Key Features
- Client-side end-to-end encryption with AES-GCM and keys derived via PBKDF2
- Zero-knowledge storage: server only receives encrypted payloads plus limited metadata
- Optional password protection in addition to the secure link key
- Expiration (TTL) and delete-after-reading (self-destruct) options
- Secure file attachments alongside notes
- Optional email/password authentication for creating notes
- Responsive minimal UI with dark mode and internationalization
- CLI for creating and viewing notes from the terminal
Use Cases
- Securely share credentials, recovery codes, or sensitive snippets with expiring links
- Send confidential one-time notes to teammates or clients
- Share private files quickly without giving the server access to contents
Limitations and Considerations
- Losing the note link (and password, if set) makes the content unrecoverable by design
- The service stores metadata such as TTL and whether a note is password-protected
Enclosed is well-suited for teams or individuals who need quick, secure, ephemeral sharing with a simple interface. Its zero-knowledge design and optional self-destruct controls help reduce exposure when exchanging sensitive information.
