Shadow Messenger

---

Shadow Messenger is a covert, AI-enhanced messaging system built for the post-quantum era. Designed for offline use and national security-grade confidentiality, it empowers secure field communication without exposing critical data to digital surveillance or interception. 

At its core is the Little Tone Key Exchange Protocol — a proprietary soundwave-based encryption mechanism enabling undetectable key exchanges through inaudible audio patterns. This protocol forms the backbone of Shadow Messenger’s zero-trace communication, ensuring sensitive operations remain invisible to even the most advanced surveillance technologies.

Built for high-stakes, high-risk environments, Shadow Messenger leverages AI-verified message integrity, mission adaptability, and stealth encryption to serve defense, intelligence, and field agents operating under extreme constraints.
