Description
This module discusses all the core principles of Cryptography: Authentication, Availability, Confidentiality and Integrity.  You’ll learn how companies and penetration testers use these to their advantage and you’ll learn some of the techniques they use along the way. The topics explored in the Cryptography Module include:
  • Whiteboard, which explains the interrelationship and the basic principles you must master for this module
  • And the following simulation labs:
    • Hash My Files Lab
    • Hash Calc Lab
    • CryptTool Lab
    • Advanced Encryption Package Lab
The Cryptography as a field is quite in depth.  We explore this in great detail in our Cryptography and CompTIA CASP courses. [toggle_content title="Transcript"] Hi, Leo Dregier here. This is one of my favorite subjects - cryptography. We're going to talk about all of the principles that are in play - confidentiality, integrity, availability, authentication and we're going to talk about how companies use cryptography or secrecy to their advantage, but also how penetration testers can use secrecy to their advantage as well. So there's lots of different tools and techniques, and different types of attacks. That's kind of the basic stuff here. But there's a big difference between what happens academically versus professionally. Academically, there's a whole history of modern cryptology and, you know enough information, and write college courses on this stuff. At the end of the day, professionally speaking, most of the time, it's just simply click a button. Either you're going to encrypt something, or you're not. Or you're going to hash something, or you're not. So we're going to see how this works in the world, and why people aren't taking advantage of simple things like hashing, and how the penetration tester can take apart that process, and use it to his or her advantage. So let's go ahead and start with the basics of cryptography. [/toggle_content]
