The pin would just be for coordination, not encryption.

  Ah ok. How is the encryption key, if there is one, established then?

    I think they just use the encryption and key exchange that WebRTC has cooked in https://datatracker.ietf.org/doc/html/rfc5764 https://datatracker.ietf.org/doc/html/rfc5764

      tl;dr: One peer generates a self-signed certificate and sends the fingerprint of that over the signalling channel; the other connects to it as a "client". The resulting DTLS keying material is subsequently used for SRTP encryption (for media) and SCTP over DTLS (for the data channel, which is presumably what's being used here).
