There is such a windows application that communications with the server through https protocol, it is an auction tool and works only several hours per month. I have captured network packets (by windows network monitor) during one auction.
I am wondering whether it is possible to mimic this client, by analyzing the the packets I collected (or any packets I could collect in future auctions). I know from this wireshark artical "Secure Socket Layer (SSL)" that it should be possible (and without much effort) to descypt the entrypted messages from server, but how? And is it possible to dectrypt the messages sent by client to server, too?
