How to Decrypt TLS Traffic in Wireshark Using Session Keys (Chris Greer)

TLS Decryption in Wireshark (Chris Greer)

Chris Greer’s walkthrough on decrypting HTTPS traffic in Wireshark is one of those rare tutorials that makes a pretty intimidating topic feel surprisingly doable. He breaks down how TLS 1.3 session keys work, why you normally can’t peek inside encrypted packets, and how a simple environment variable on Windows lets you capture those keys right from your browser. It’s approachable, but still nerdy enough to scratch that packet‑analysis itch.

The core trick is setting the SSLKEYLOGFILE environment variable so Chrome writes out the session keys as it negotiates TLS. Once you’ve got that log file, Wireshark can use it to decrypt the encrypted streams in real time. Chris walks through the exact steps—Control Panel, Advanced System Settings, Environment Variables—and shows how to plug the keylog into Wireshark’s TLS preferences. If you’ve ever wanted to see what’s actually happening inside HTTPS without guessing, this is the cleanest path in.

How to Remotely Stop a Wireshark Capture When Using Tshark or Dumpcap

How to Remotely Stop a Wireshark Capture When Using Tshark or Dumpcap

One of the advantages of installing Wireshark, is working with and learning the various command line utilities that come along with it. Programs like tshark and dumpcap allow you to capture from the command line. This gives the analyst a lot of flexibility in the field.

For example, you might create a shortcut on a client’s desktop so they can capture packets for you. You can also create a batch file so the system starts capturing when it powered on, which is very helpful when I build remote capture devices.

Tshark and dumpcap can capture with specific parameters like ring buffers, filters, etc.

One popular question I get asked is how to stop dumpcap or tshark after you start it. Normally you would press Ctrl+C to stop the capture. I have to admit that the solution I came up with, is not very elegant, but works.

Eat That Frog! for Students: A Review (Paul W. Smith)

 

Eat That Frog! for Students: A Review (Paul W. Smith)

I approached this book as a life-long learner, undaunted by the promised focus on students. From this perspective, the lessons apply to both college students and those in a career where progress requires keeping up with the latest knowledge. Eat That Frog! For Students by Brian Tracy is much more than just the time-management book noted on the cover – it outlines a life-sized strategy for success in the context of a detailed plan for dispatching undesirable tasks and dealing with the stress that life inevitably brings, both in and out of school.

Both videos illustrate current IT problems. The first problem refers to about complex it has become to test your network. Validation is a critical function as it lets us find out the truth about our network and how well it is, or is not, functioning. The good news is that there are applications available that make this effort much easier now.
