SecNote โ€” open-source E2EE read-once notes

SecNote is an open-source, zero-knowledge relay for sharing sensitive notes that should be opened only once. Notes are encrypted in the browser with AES-256-GCM before they leave the client, and the decryption key stays in the URL fragment so the server never receives it.

The backend stores only ciphertext in RAM, never writes note contents to disk, and atomically destroys each note after the first successful read or when it expires. No account is required.

Key features

  • End-to-end encrypted notes with browser-side AES-256-GCM
  • Read-once / burn-after-read delivery
  • Zero-knowledge server that stores only ciphertext
  • RAM-only storage with no persistent note database
  • Accidental burn protection using a key-derived view token
  • Proof-of-work anti-spam protection instead of traditional CAPTCHA
  • Signed server responses with Ed25519 verification
  • Public-key pinning / TOFU support for stronger trust boundaries
  • No accounts, no login, no tracking workflow
  • Self-hostable Rust backend
  • Offline-capable static frontend with no CDN dependency
  • Tor Browser-friendly design

SecNote is built for developers, security-conscious teams, journalists, administrators, and privacy-focused users who need a minimal way to exchange short secrets without relying on accounts, persistent storage, or server-side plaintext handling.

OneTimeNote features and specs

  • Security
    OneTimeNote offers enhanced security by allowing users to create notes that can only be accessed once, reducing the risk of unauthorized access to sensitive information.
  • Simplicity
    The platform is straightforward to use, allowing users to quickly create and share secure notes without the need for complex setups or registrations.
  • Privacy
    OneTimeNote does not require user registration, enhancing user privacy by ensuring that personal data is not stored on their platform.
  • Ephemeral
    Notes self-destruct after being viewed, ensuring sensitive information does not remain accessible indefinitely.

Possible disadvantages of OneTimeNote

  • Lack of Persistence
    Since notes are designed to be viewed only once, users cannot retrieve information if they miss or accidentally close it, potentially causing inconvenience.
  • Limited Features
    Compared to other secure note-sharing services, OneTimeNote may lack additional features such as note organization or rich formatting options.
  • Reliance on Forgetfulness
    Users must rely on the trust that their recipients will not accidentally or intentionally misuse the information, as there is no way to track access once the note is destroyed.
  • No User Support
    Without requiring registration, there's a limited scope for customer support or recovery options in cases where issues arise with note access.

Analysis of secure-notes

Overall verdict

  • Secure-notes (pwn-all.github.io) appears to be a niche or lesser-known tool, and without verified, up-to-date information about its security practices, ownership, or track record, it cannot be confidently endorsed as 'good' for storing sensitive information. Users should exercise caution and verify its legitimacy, encryption standards, and privacy policy before use.

Why this product is good

  • Claims to offer note-taking with a security focus, which may appeal to privacy-conscious users
  • Potentially lightweight or simple to use if hosted as a static GitHub Pages site
  • GitHub Pages hosting can imply transparency if the source code is open for review

Recommended for

  • Users who first verify the source code and security claims independently
  • Casual note-taking where no sensitive personal or financial data is involved
  • Developers or technically savvy users comfortable auditing open-source code before trusting it with data
