Video Description

Welcome to the free Cybrary online course Cryptography. To help you fully understand and grasp the concepts of Cryptography, the Cybrary Cryptography module is divided into three sections, each taking a detailed, intimate focus on the concepts, tools and techniques that are absolutely essential for penetration testers and ethical hackers to master. In this series on Cryptography, we look at confidentiality, integrity and authentication. We'll look at how companies use secrecy to their advantage and explore how penetration testers and ethical hackers can secrecy to their advantage as well. We're now in Section 1 of the Cybrary Cryptography module. In this Section, we'll introduce and explain the basic principles behind the science and practice of Cryptography both from an academic perspective as well as the practitioners' perspective from the field. The topics covered in Section 1 of the Cryptography module are as follows: - Whiteboard, which outlines the interrelationship of all the basic principles and components of Cryptography you'll need to understand - And the following subsections introducing Cryptographic Tools and how to use them: - Cryptography Part 3.1 - Cryptography Part 3.2 Section 2 of the Cryptography module is quite extensive and very hands-on. Parts 3-7 breaks down even further Cryptographic Tools introducing more techniques, a lab and an advanced discussion on encryption. Follow along with the following subsections: - Cryptography Part 3.3 – Cryptographic Tools - Cryptography Part 3.4 - Confidentiality - Cryptography – CryptTool Lab - Cryptography Part 4 – Symmetric Encryption - Cryptography Part 5 - Symmetric Encryption Extended - Cryptography Part 6 – Pros and Cons of Symmetric Cryptography - Cryptography Part 7 – Public Key Cryptography And finally, Section 3 of the Cryptography module continues exploring Cryptographic Tools with discussion and demonstration of Asymmetric Cryptography. View our labs and in-depth discussion in the following subsections: - Cryptography Part 8 – Asymmetric Cryptographic - Cryptography Part 9 - Cryptography - Cryptography – Advanced Encryption Package Lab - Cryptography – Part 10.1 - Cryptography – Hash Calc Lab - Cryptography – Part 10.2 - Cryptography – Hash My Files Lab Upon completion of this Cybrary Cryptography module, you'll understand how Cryptography works, what principles are in play, and what tools you'll need to master to become the go-to pentester going forward. Please note that Cryptography is a complex topic. We explore Cryptography in great detail in the Cryptography Module #19 of our Penetration Testing and Ethical Hacking course, as well as in our CompTIA CASP courses.

Hi, Leo Draeger here. This is one of my favorite subjects. Cryptography.
00:08
We're gonna talk about all of the principals that Aaron play confidentiality, integrity,
00:14
availability, authentication. And we're gonna talk about how companies use cryptography or secrecy to their advantage, but also how penetration testers can use secrecy to their advantage as well.
00:27
So there's lots of different tools and techniques in 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 the whole history of modern photography, and you know, enough information that right
00:46
college courses on this stuff.
00:48
At the end of the day, professionally speaking, most of the time it's just simply click a button. Either gonna encrypt something or you're not, or you gonna hash something or you're not. So we're gonna see how this works in the world and why people aren't taking advantage of simple things like hashing and how the penetration test There
01:06
can't take apart that process
01:07
and use it to his or her advantage. So let's go ahead and start with the basics of cryptography
