TLS met on Tuesday Afternoon.  The raw public key draft has completed IETF last call.   The cached info draft will be reviewed by the DICE working group.  The ALPN draft is under discussion due to issues with some servers dropping clientHellos of particular sizes.  TLS-PWD will be heading to working group last call.   The room voiced support for adopting the TLS BCP draft, but a new revision will be necessary before working group adoption.   We discussed several approaches to migrate to encrypt then mac for CBC mode, more discussion on the list is necessary to determine the approach.  We had a presentation on ChaCha20 based cipher suites and there was general support for it in the room.  We discussed different protocol flows to reduce the round trips for the TLS 1.3 handshake and to initiate encryption earlier in the TLS 1.3 handshake.
