Covert a Image to Vector Graphics Format for Free

InsightsLeave a comment

I had one of my clients call me today and say he wanted to make some T-shirts with his logo picture, that I was using on his website. I said OK and sent him the .jpeg file. He called me back twenty minutes later and said his T-shirt guy wanted the image in a vector graphics format. Now I am not sure why the T-shirt guy wouldn’t have the software to convert it however thats not my problem. In any case I always like to try to find free software to complete tasks like this. I have used a program called Inkscape in Linux many times but I had no idea what to do in Windows. Fortunately, there is a version of Inkscape for windows.

How to Merge Multiple WLAN (IEEE 802.11) Captures into One File

Insights2 Comments

I recently had a customer upload a WPA capture to our tools.question-defense.com server which failed immediately. This can happen from time to time and is for a variety of reasons Sometimes if captures does not contain all 4 eapol packets they will fail , and sometimes if a capture has lots of other wifi garbage in the .cap file it can confuse the cracking program. This last time was a new situation. After the fail I analyzed the cap file and determined that the essid was not present in the capture. This is absolutely crucial for the decrypting process. In this short article I will show how I determined the essid was not present and what I did about it.
