 > A wrapper around [webrtc-swarm](https://github.com/mafintosh/webrtc-swarm) that adds peer whitelisting and authenticated asymmetric encryption of the WebRTC signaling data using [TweetNaCl.js](https://github.com/dchest/tweetnacl-js
 ) (see [algorithm.md](algorithm.md)).
 
-When connecting multiple peers via [webrtc-swarm](https://github.com/mafintosh/webrtc-swarm) personal information like available IP addresses are exchanged via a central thin server. `secure-webrtc-swarm` completely enctypts this data stream and prevents in-transit manipulation by signing data packages.

-To achieve this additional data must be exchanged between the peers out-of-band before the connection initiation can happen. In the simplest case this could be a shared secret or more granular an invite-acceptance procedure.
