I'm analyzing a TLS1.3 handshake using latest version of wireshark and I can't find the certificate in the handshake (I know that the certificate in TLS1.3 is sent encrypted). In which packet can I find the certificate sent by the server ?

3.2.1 (Git commit bf38a67724d0) on Ubuntu

Same display in Version 2.6.10 (Git v2.6.10 packaged as 2.6.10-1~ubuntu18.04.0)

How could I get the same display as in the screenshot. When I open the pcap there is only Client Hello, Server Hello and Application Data

What version of Wireshark?
Did you add the keyfile to the TLS/SSL protocol settings?
