You should see a lot of http traffic popping up on Wireshark now. Open up a new Window using Google Chrome and navigate to a Web site that uses https. Since we’re now logging the SSL keys and exporting them into the SSLkeylogfile.txt file, Wireshark will collect these keys and decrypt the https traffic into http traffic. Type the filter “http” in the filter bar. Now, let’s start capturing traffic again using Wireshark. Under the Protocols drop down list, click on “SSL.” Under the “(Pre)-Master-Secret log filename, you will post the path for the.

Press Ctrl + Shift +P to open the Preferences box. Then, post the path to the SSLkeylogfile.txt file. Type “SSLKEYLOGFILE” in the variable name bar. Name your text document “SSLkeylogfile.txt.” Now, go back to the Environmental Variables box and click the “New” button at the bottom pane. Now, click on the “Environmental Variables…” box. However, if we navigate to Control Panel > System and Security > System, you will see the following:Ĭlick on the “Advanced systems settings” option to open up the System Properties box. We can’t make much use of that since its encrypted. If you don’t have Wireshark, you can download it for free here.Īs you can see in the highlighted area, there is just a bunch of random characters. First let’s start by capturing some regular SSL-encrypted traffic on Wireshark, the protocol analyzer. Wireshark possesses a cool feature that allows it to decrypt SSL traffic. I’ll show you another way of decrypting SSL traffic using Wireshark and Google Chrome. You can read more about KRACK attacks here. As we’ve seen with the latest KRACK attacks, it is entirely possible to decrypt a victim’s https traffic. But, SSL is not as safe as we originally thought it was.

Therefore, we refer to TLS as SSL version 3 (SSLv3). These days, however, most of our Web servers are utilizing Transport Layer Security (TLS 1.2), which is an updated version of SSL 3.0. This is because https uses the Secure Sockets Layer (SSL) encryption scheme to pass keys between two parties over the Internet. Hypertext Transfer Protocol over SSL (https) is pretty decent security.
