This project is a secure chat application built with React, WebCrypto API and PeerJS. It utilizes WebRTC for peer-to-peer communication and ECDH for key exchange to establish a secure channel.

• Peer-to-peer communication using WebRTC.
• Secure key exchange with Elliptic-curve Diffie–Hellman (ECDH).
• Encryption and decryption of messages using AES-GCM.
• Unique chat room links for initiating a chat.
• Short Authentication String (SAS) for confirming the identity of participants.
