Paranoia Text Encryption VS secure-notes

SecNote — 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.
