// If using SDP and SDES (RFC4568) for signaling, then after applying the
// answer, the negotiated keying information from the offer and answer would be
// set and the SRTP would be active.

// RTCSrtpSdesTransport:

// There are some limitations of the current implementation:
// 1. Send and receive keys must use the same crypto suite.
// 2. The keys can't be changed after initially set.
// 3. The keys must be set before creating a sender/receiver using the SRTP
// transport.
// Set the SRTP keying material for sending RTP and RTCP.
