Documentation

Meshenger exchanges the contact name, public key and MAC/IP/DNS address via QR-Code. By default, only a MAC address is transferred as address and then used to create an IPv6 link local address to connect to the contact. This does not even need a DHCP server. The exchanged public key is used to authenticate/encrypt signaling data to establish a WebRTC session that can transmit audio and video.

Details can be found in the Documentation or in the FAQ.
