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. I really like the way Wireshark handles the SSL decryption process. Cryptography is complicated, and the standards are constantly changing to be more secure. But once Wireshark and your environment are set up properly, all you have to do is change tabs to view decrypted data. The data field at the bottom of the main Wireshark page will show the decrypted contents of the packet.

The two-way SSL handshake authenticates both the server and the client. Here are the steps that are carried out in this process:. However, you will always need the RSA key in order to decrypt traffic. This site uses Akismet to reduce spam.

Ever tried using Wireshark to monitor web traffic? You've probably run into a problem? A lot of it is encrypted. Remark that for packets 9 and 10, the Protocol column value changed from TLSv1. But remark that there is some data duplication, this is possibly a bug in Wireshark. To be investigated. RSS feed for comments on this post. TrackBack URI. You are commenting using your WordPress.
