📁 Repository Name:

WebRTC-VideoChatApp-with-True-EndToEndEncryption-Enabled

---

📝 Description:

A browser-based WebRTC application that enables secure, real-time video and chat using End-to-End Encryption (E2EE). Built with Insertable Streams, ECDH key exchange, and AES-GCM encryption, this project demonstrates secure peer-to-peer communication without server-side access to media.
