Log Entry 4

Circa March 2020

After the initial packet capture (explained in log 3) we found more success with further configuration and trail/error. The client and server are now exchanging data properly and we can see the 1-RTT and 0-RTT happening before our very eyes. you can view the packet capture yourself from here. Please not we are not 100% sure what each individual packet is.

Packet Analysis of Initial 1-RTT

Packet 1: Client Inchoate CHLO.
Packets 2-4: Server REJ and sending client the scfg and stk.
Packet 5: Believed to be the completion of the initial client request.
Packet 6: Believed to the the completion of the server sending the client connection parameters.
Packet 7: Completed CHLO and client request of www.example.org.
Pacets 8-17: These packets must include the SHLO and the encrypted reponse. Some of the packets we are not entirely sure of.

Packet analysis of 0-RTT

With the cached connection parameters, the client can initiate a conenction and make a request to the server with 0-RTT.
Packet 21: First packet of CHLO.
Packets 22-24: SHLO.
Packets 25-31: Must include completion of client request and SHLO along with the encrypted message from the server. Difficult to say which packets are totally which.
