How does it work?

Secure share client will get ICE Candidate from STUN/TURN server and make a connections between peers.

Thanks to the Interactive Connectivity Establishment (ICE) protocol, Two peers will have the shortest path to travel between them without caring the Network address translation (NAT).

WebRTC protocol will secure by DTLS (Datagram Transport Layer Security) But DTLS can be vulnerable to man-in-the-middle (MITM), So we provide a second layer encryption using PGP (RSA-OAEP-1024, AES-128).
