Hi,
I want to decrypt the TLS tunnel data,
So far i have extracted client Key exchange message.
Which has pre master Key,Decrypted with Root Private Key,
Got 48 bytes of
(MK)*Master_key*=PRF(Pre-Master-Key,"*master key*
",Client.random|Server.random).

And derived 64 bytes
(TK)*TunnelKey* (Master-Key,"*Client EAP encryption*
",Client.random|Server.random)

Which is the key to encrypt/decrypt TLSV1 application data.

Is tunnel Key is used to encrypt decrypt data.


Thanks & Regards
Harsha
