The log file should start to increase in size as it logs the symmetric session keys. Restart Firefox or ChromeĪfter browsing to a HTTPS site. Configure Wiresharkįrom the drop-down menu select Edit | Preferences | Protocols | SSL | (Pre)-Master-Secret Log Filename - Browse to the log file you placed in your environment variable. Under advanced system settings, select Environment Variables and add the variable name SSLKEYLOGFILE with the variable value as the path to where you want the file saved. Linux / Mac export SSLKEYLOGFILE=~/sslkeylogfile.log With these keys, Wireshark can show you the session fully decrypted for the win! 1. If Firefox or Chrome are loaded using a special environment variable, the individual SSL/TLS session symmetric keys will be logged to a file that Wireshark can read. Hence, there is another option for easily viewing the browser SSL/TLS traffic from your local system. You are not always going to have access to the servers private key. For example, in a browser session you could see the plain text HTTP. Using this key, you can decrypt the session and view the protocol under the SSL/TLS layer. One way of decrypting SSL/TLS sessions is to use the Private Key from the server that is being connected to by the client.

This is a good way to find software (malware even) that is communicating with the Internet using unusual protocols. Try generating a filter combination that shows all non HTTP and HTTPS traffic leaving your local system that is not destined for the local network. IP Address Filter Examples ip.addr = 192.168.0.5 The results will now only show HTTP (tcp port 80) traffic. The easiest filter is to type http into the filter bar. As seen here, you can filter on MAC address, IP address, Subnet or protocol. A primary benefit of the filters is to remove the noise (traffic you don't want to see). You enter these expressions into the filter bar (or on the command line if using tshark). The filters are easy to read and self-explanatory. When you have captured an HTTP session, stop the capture and try playing with a few basic filters and the Analyze | Follow | HTTP Stream options. This allows the network card to enter promiscuous mode.Īfter running an initial capture you will see the standard layout and the packet details that can be viewed through the interface. Pretty straight forward, you will also be installing a packet capture driver.
