| # What is 0-RTT | ||
|
|
||
| Iroh connections are just peer to peer QUIC connections, using a fork of the quinn rust crate. QUIC is using TLS for encryption. |

| ### ClientHello | ||
|
|
||
| Like before, the client sends a `ClientHello` message. The `ClientHello` for a connection attempt using 0-RTT must contain a set of ids of pre shared keys, otherwise it is not possible for the server to decrypt subsequent user data before the full handshake is complete. In addition it has an `early data` flag set. |

Double checking: you're sure that in QUIC's use of TLS the early data flag is also set when using 0-RTT? I hope your wireshark captures could confirm this.

if there is no early_data flag, you are not allowed to send early data. So I would assume that it is set.
I think both Phillip and dig are quite busy. And I am pretty sure that the basic mechanism is correct. If there is some tiny error people can complain about it and provide some additional publicity... |
