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.

  • Occasional Stability Issues
    Users have reported occasional performance and stability issues, particularly during high-demand periods, which can slow down the build process.
  • Configuration Complexity
    If not properly managed, the YAML configuration files can become complex and difficult to maintain for larger projects, leading to potential misconfigurations.

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
