Wireshark · Wireshark-users: Re: [Wireshark-users] AIRPCAP and wireshark 1.8.4

[Giuseppe Montanarella <giuseppe.montanarella@xxxxxxxxx>]

Maybe I did not explain properly.
I use wireshark 1.8.4 and I want to understand what traffic goes in my wifi,
if I go to set the network key to decrypt the traffic, the password is not stored and can not decrypt the traffic,
Someone using Windows and AirPcap to sniff wireless?

Thanks
Giuseppe

Doubtful, these guys are pretty good. What is probably more likely is that you are attempting to view a cached SSL session which bypasses the full SSL key exchange. I can't remember where in the I saw/heard this, but I can tell you from personal experience that Wireshark can only decrypt SSL when the entire key exchange sequence has been captured. I'm sure someone on this board who is a lot smarter than me will give you a better way, but I can typically tell if the SSL session is cached because the Server Hello packet is approximately the same size as the Client Hello - meaning that the certificate was never transmitted. In a full key exchange, the entire certificate is transmitted which typically results in  one or more full-sized TCP segments before Wireshark rolls them up into a Server Hello in the Info column.
