 When the BigBlueButton client loads, it makes data connections back to the BigBlueButton server using a web socket connection encrypted HTTPS.  When the BigBlueButton shares the user's audio, video, or screen, the browser uses the built-in web real-time communication (WebRTC) libraries that transmit real-time protocol packets (RTP) over user datagram protocol (UDP) via Datagram Transport Layer Security (see [DTLS](https://en.wikipedia.org/wiki/Datagram_Transport_Layer_Security)).  Furthermore, to provide communications privacy for datagram protocols the media packets are  encrypted using Secure Real-Time Protocol (see [SRTP](https://en.wikipedia.org/wiki/Secure_Real-time_Transport_Protocol)).
