In the (Pre)-Master-Secret log filename field, enter the path to a file where you want to save the (Pre)-Master-Secret values. In Wireshark, go to Edit > Preferences > Protocols > TLS. Start Wireshark and capture traffic from the browser to the WCF service. Here are the steps on how to decrypt TLS 1.2 data using Wireshark on a connection from the browser to the WCF service using the (Pre)-Master-Secret method: Decrypting traffic without proper permission may violate privacy and security guidelines. Keep in mind that decrypting TLS traffic should only be performed on your own network or with proper authorization. This means that you need to capture the traffic in real-time to obtain the necessary cryptographic information. Note: The (Pre)-Master-Secret method requires capturing the handshake packets and exporting the session keys during the capture. You should now see the decrypted TLS 1.2 data in the Wireshark capture, allowing you to inspect the exchanged messages between the browser and the WCF service. Wireshark will attempt to decrypt the TLS traffic using the provided (Pre)-Master-Secret. Open the captured TLS 1.2 traffic in Wireshark. In the Preferences window, select "Protocols" > "SSL."Ĭlick on "Browse" next to the "(Pre)-Master-Secret log filename" option.īrowse and select the ".key" file containing the exported (Pre)-Master-Secret.Ĭlick "OK" to close the Preferences window. ![]() Go to "Edit" > "Preferences" (or "Wireshark" > "Preferences" on macOS). Save the exported packet bytes to a file, preferably with a ".key" extension.Ĭonfigure Wireshark to decrypt the TLS traffic: Right-click on it and choose "Export Packet Bytes." In the SSL/TLS session details window, locate the "Pre-Master-Secret" or "Master-Secret" value. Right-click on one of the TLS handshake packets and select "Follow" > "SSL" or "TLS" to view the details. These packets contain the (Pre)-Master-Secret required for decryption. Locate the TLS handshake packets in the captured traffic. Reproduce the desired network connection between your browser and the WCF service, ensuring that the TLS 1.2 traffic is captured by Wireshark. Open Wireshark and start capturing network traffic on the appropriate network interface. Install the latest version of Wireshark on your system.Ĭonfigure your browser and Wireshark to capture the network traffic between the browser and the WCF service. Here's a high-level overview of the process: 1-ĭecrypting TLS 1.2 data using Wireshark requires capturing the encrypted network traffic and obtaining the necessary cryptographic information, including the (Pre)-Master-Secret. ![]() Step-by-step instructions to decrypt TLS traffic from Chrome or Firefox in Wireshark: ![]()
