DTLS-SRTP Media Security
WebRTC media is always encrypted. DTLS-SRTP is the protocol that does it. Know it when troubleshooting media security negotiation or DTLS handshake failures.
What It Defines
Defines how WebRTC secures media: DTLS (TLS over UDP) for key exchange, SRTP for encrypted audio/video streams. Mandatory encryption for all WebRTC media paths.
Canonical (Normative)
The canonical publication point for finalized RFCs. If a protocol is standardized as an RFC, the RFC Editor text is the normative final reference. Published by the IETF, IRTF, IAB, and independent stream.

Every HTTPS connection, SMTP/IMAP over TLS, OAuth token exchange, and API call uses TLS. It is the foundational security layer.
