Hi,

I'm analyzing a couple of wireless sniffer logs and trying to dig into the key exchange messages passed during the 4-way handshake process. Specifically I need to decrypt the encrypted key data field of message 3/4.

Can this be done already with Wireshark? If not supported I'm thinking Wireshark might already internally decrypt this field to get the GTK and verify PTK. With slight modification I can perhaps get this printed to the console as first step.

Any advice on how to proceed would be great. If I get this working I'll make an attempt on adding support for dissecting this properly.
