Wired Equivalent Privacy (WEP) was introduced in 1999 as a part of 802.11 standard. It's puprose was to assure the privacy of the wireless network in a way near to wired networks. It's using RC4 cipher (with different key size: 64 and 128 bits) and CRC-32 checksum to mantain integrity. In addition WEP is using a short, 24 bit initialization vector (IV), which is added to the key provided by user, creating 'unique' for each packet RC4 key. But because the IV is so short, and it's used with the same key, WEP is now considered outdated, easy to crack and insecure.
Vulnhub.com - Stapler
Todays challenge is going to be more security concerned as we're going to give a try boot2root machine from Vulnhub called Stapler. It's aimed for begining/intermediate pentesters, with goal to get root access. Let's jump straight into the content!
Three Coding Challenges
Hi, today we're gonna explore more about programming and math. I've chosen 3 challenges from Project Euler- Largest Prime Factor of a number, Largest Palindrom and 10001st Prime. Project Euler is a great site that provides us with many mathematical/programming problems that will undoubtedly help us gain a better insight in beautiful word of mathematics and programming.
Simple Password Generator
As a part of my weekly coding challenges I decided to create simple password generating program that allows an user to create strong and unique passwords depending on the wanted legth. It's great way to improve your programming skills and problem solving. Let's see how it works!
