In this tutorial, we are going to capture the client side session keys by setting an environment variable in Windows, then feed them to Wireshark for TLS 1.3 decryption.

Follow along with me by downloading the trace file and keylog file here:
https://bit.ly/tlsdecrypt

Steps to capture client session key:
Open Control Panel:System
Select Advanced System Settings
Select Environment Variables
Add a new variable: SSLKEYLOG
Save to a location with a name ending in *.log
Restart Chrome (You may have to reboot Windows in some cases)
Capture Traffic
Add the keylog file to the TLS Protocol in Wireshark Preferences.
