029. Think Like a Computer: Putting the "Crypt" in Cryptography

Happy summer, cyberheads! Like many of you, our guests are on break and out of office, so we have some special edition episodes just for the summer. Don't worry, guests will be back to chat with us in the fall. But until then, join us on #CyberChats as we stay cool in the summer heat and dive into the freshest topics in cyber.

In today's episode, we dip our toes into an introduction to cryptograhy. What is cryptography? Why do we need cryptography? How does cryptography work? To answer these questions, we'll talk about how computers think -- while you and I might look at a picture and see colors, a computer can't think in colors. So, how do computers understand reds, blues, and greens in images? Tune in to find out.

After the episode, put your new knowledge to practice in our first of three Summer Cyber Challenges on MetaCTF: HexCryption! Register below, compete individually or join a team, and look for your name on the leaderboard. Be sure to come back here in two weeks as we work through the Challenge together.

Topics discussed: cryptography, binary, hexadecimal number systems, computers.
