Five empty lines separate item 1. Client hello and item 7. Certificate. Two empty lines separate item 11. Finished and item 14. Finished.
The Server list contains the following items:
- 2. Server hello

- 4. Certificate request optional
- 5. Server key exchange optional

An arrow points from each item in the Client list to the corresponding empty line in the Server list. Similarly, an arrow points from each item in the Server list to the corresponding empty line in the Client list. For items 14 and 15 in the Client and Server lists, double-headed arrows connect them instead.
