The certificate fingerprint used in DTLS.

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
