I am trying to decrypt the 802.11 traffic,
To decrypt the data i have to derive "Pairwise Master Key "

can any one help me derive PMK for attached *Cap file*   *

And *PrivateKey* file is *http://www.sendspace.com/file/w8bd9t*

I am not clear when is EAP-TLS is started and how to decrypt the text inside
Please help me derivePK

what i have read is

PMK=TLS-PRF (Master Key, ”Client EAP encryption “ I clientHello.random I

can any one explain with example for the above PrivateKey and the cap file.
what will be my PMK ?.

Are client random and server random encrypted or they are in plane text

And how to extract Master Key from .pem file

Thanks a lot
