Using Wireshark, you can look at the traffic flowing across your network and dissect it, getting a peek inside of frames at the raw data. It uses various encryption methods to secure data as it moves across networks. SSL encryption makes using Wireshark more challenging because it prevents administrators from viewing the data that each packet carries.

When Wireshark is set up properly, it can decrypt SSL and restore your ability to view the raw data. Using a pre-master secret key to decrypt SSL in Wireshark is the recommended method.

A pre-master secret key is generated by the client and used by the server to derive a master key that encrypts the session traffic. Start by right-clicking on My Computerand selecting Properties from the menu. The System menu will open. Next, click Advanced system settings on the list to the left. The System Properties window will open. Click the New… button under User variables. In the Variable value field, type a path to the log file. You can also click the Browse file… button and specify the path using the file picker.

Before you launch Wireshark and configure it to decrypt SSL using a pre-master key, you should start your browser and confirm that the log file is being used. In Windowsyou can use Notepad. In Linux or Macuse the following command:. On any operating system, your file should look like mine does above. Open Wireshark and click Editthen Preferences.

Expand Protocolsscroll down, then click SSL. Browse to the log file you set up in the previous step, or just paste the path. The final step is to capture a test session and make sure that Wireshark decrypts SSL successfully.

But any encrypted traffic that uses a pre-master secret key will work with this method. You should see an entry for Decrypted SSL data, among others. When you click the Uncompressed entity body tab, which only shows up in this case with SSL decryption enabled, you can view the source code of the site. In practice, RSA key decryption is deprecated. If you were previously using an RSA key to decode traffic, and it stopped working, you can confirm that the target machine is using Diffie-Hellman exchanges by enabling SSL logging.

To turn on logging, click Edit from the toolbar menu and select Preferences. Expand the Protocols menu item on the left and scroll down to SSL. From here, you can click the Browse button and set the location of your SSL log.

Capture a session with your SSL-enabled host, then check the logs. Specifically, you should scroll until you find the frame that the TLS handshake was negotiated on. That means Diffie-Hellman key exchanges are enabled.
