VoidNote

Zero-knowledge,
self-destructing
notes.

Encrypt in your browser, share a link. The server stores only ciphertext — the decryption key lives solely in the URL. When the recipient reads it, the note destroys itself.

  • AES-256-GCM encryption, entirely client-side
  • Server never holds the decryption key — zero knowledge
  • Self-destructs on view count or 24-hour expiry
  • SDK for TypeScript, Python, Go, Rust, Zig, Java + CLI
token a1b2c3d4…e5f6a7b8…
lookup key
→ server secret key
in URL only
key = SHA-256( secret )

Void Stream

Encrypted real-time
ephemeral
channels.

Open a live channel and pipe anything into it — deployment logs, credentials, structured data. End-to-end encrypted; the server routes ciphertext it cannot read. When the writer closes it, the channel is gone.

  • End-to-end encrypted — server routes, never reads
  • Pipe any output: deployment logs, secrets, data
  • Auto-destroys when the writer closes the channel
  • Same SDK interface, every language — create, write, watch, close
