NoteDaemon - Secure IO Daemon - (currently Linux only)

NoteDaemon provides exclusive access to input devices, bypassing OS-level input systems for secure password entry and other security-critical input scenarios. Features

    -Exclusive Device Access: Detaches kernel drivers to prevent input interception
    -Protocol Negotiation: Multiple modes (RAW, PARSED, ENCRYPTED)
    -End-to-End Encryption: Diffie-Hellman key exchange + AES-256-GCM
    -Secure Buffer Handling: Automatic zeroing of sensitive data

Protocol

Utilizes Netnotes binary object model NoteBytes Wire Protocol Format
