The certificate fingerprint used in DTLS.
Description
String
The fingerprint of the certificate used for the DTLS handshake. This is the same value that appears in the SDP as the "a=fingerprint" attribute. Format is a colon-separated hex string (e.g., "AB:CD:EF:...").

Notes
- The fingerprint is critical for DTLS-SRTP security - it is exchanged during signaling (in SDP) and verified during the DTLS handshake to prevent man-in-the-middle attacks. A mismatch between the signaled fingerprint and the one presented during DTLS will cause the handshake to fail
