Wireshark-users: Re: [Wireshark-users] Help with SSL Traffic decrypt / Analysis

Hi Kenneth,
 
    Thanks for your response.  We have the following interactions (all over HTTPS):
 
1. Client -> Server1 (over https).
2. Server1 -> Redirect to Server 2 (through the browser using 302 response code)
3. Server2 -> Server1 (again over https)
4. Server1 -> Server2 (response to request in Step 3).
5. Server2 -> Client (response to request in Step 2).
 
    We want to monitor this communication trail and decrypt the SSL traffic (as per the attached capture file).  We have been able to accomplish this for Step 1, 2 and 3 using Wireshark / tshark.  However, for some reason, the generated response in Step 4 is not being decrypted.
 
     Can you confirm / deny that our approach is feasible given that the requirement is to be able to decrypt this communication traffic?  If 'tshark' is not the right tool are there any other options (even commercial is ok) that might help us in our quest?
 
     Thanks for your response.  Kind regards,
 
Vijay
