Re: Certificate Request not being displayed by Wireshark even when that info is in the packet

Hi Peter, I'm sorry for the delay.

I've just found the "Certificate Request" in a subsequent "TCP
Out-Of-Order" packet (see https://filebin.ca/4kArOrO9xTaL).

Thank you.

I'm not an expert in the TLS protocol but I've just stumbled upon the
following packet (and I didn't have enough time to debug this further),
https://filebin.ca/4jHrWy2tkGQ6, which contains the "Certificate

list of accepted certificates, but Wireshark is failing to display it as

can be observed in https://i.imgur.com/HrKevzC.png.

Is it possibly a bug?.

Could you share a capture file with the next non-empty TCP segment?  The
hidden part is a TLS record of 3577 (0xdf9) bytes and fits a handshake
message (Certificate Request) of 3569 (0xdf1) bytes. If TCP reassembly
is enabled, it should have been reconstructed in the next TCP segment.
