What you will learn

  • Define cryptography and the key role it plays in protecting our digital data.
  • Learn how hashing helps us to be certain the data we receive or download is legitimate.
  • Find out how Web sites use certificates to make sure our usernames, passwords, credit card numbers, and other personal data stay secure.
  • Prepare for the CompTIA Security+ exam by better understanding cryptography and PKI, one of the six exam domains.
  • Understand ciphers, binary, hashing, symmetric and asymmetric cryptosystems, digital signatures and certificates, and public key infrastructure.

Course Description

Hey there! Mike Meyers, your favorite nerd, here to present a fun, casual, and informative conversation on cryptography. I partnered with my good friend, Bill Saichek, to talk about one of my very favorite topics: cryptography. I've loved the idea of cryptic codes, secret agents, and deciphering hidden text since I was a kid. And because I've had so many questions on this topic, I decided to try a different kind of course to help my students understand the more complex concepts in cryptography.

This Conversation on Cryptography course was designed with YOU in mind, whether you're just curious about cryptography (like me), or you took my CompTIA Security+ Course (or any other cyber security course) and would like a better understanding of this intriguing subject. Here's a rundown of what Bill and I talk about:

  • Caesar and Vigenere ciphers - These fascinating ciphers form part of the basic foundation of cryptography, back before the digital age when militaries, powerful leaders, and spies had to pass messages that couldn't be deciphered if they fell into enemy hands.


  • Binary - In order for ciphers to be useful today, cryptographers had to figure out how to translate them into the language of computers (1s and 0s).


  • Hashing - If all our digital data are just strings of 1s and 0s, how can we make sure we have the real deal? Learn about authentication in this episode.


  • Asymmetric cryptography - We discuss how generating a key pair offers more security, though at the price of taking more time.


  • Symmetric cryptography - This quick and dirty cryptosystem uses a single key to both encrypt and decrypt.


  • Asymmetric methods - Dig into how these methods actually work, and how prime numbers are keeping your data safe. Did we

  • mention we play with paint in this episode?


  • Certificates - The Web is full of hackers who want to take advantage of your personal and private information. So, who do we trust? That's where certificates come in.


  • Public key infrastructure - How do we pass out those certificates? And assure the authenticity of them? PKI to the rescue!


  • Living with certificates - We get our hands on some of those certificates and teach you how to troubleshoot them when something goes wrong.

So sit down, grab a cup of coffee, and join Bill & I for a conversation on cryptography.

Loved this course! But, I stumbled upon a YouTube video from 10 years ago, "Art of the Problem" published on July 30, 2012 that shows this method exactly. Maybe it's one of many, maybe it's the ONLY example. YouTube is a big place. So, Mike did credit Diffie Helman in some way, but I don't know if Mike is passing this color method off as his own or if he is taking credit away from this "Art of the Problem" channel. You decide. Here is the video - https://www.youtube.com/watch?v=YEBfamv-_do

Learning from experts is always a good thing! Not sure if it is my video/computer, but the monitor was blurry when showing file paths, although, maybe it was done on purpose, otherwise, fun to watch, and can't beat the holiday price I received. That's worth five stars alone. I guess the tension between Bill and Mike made for a comedy-type routine, but sometimes I felt sorry for Bill. Thank You!

A good introduction to the subject and the presenters make concepts easy to understand. However the details get a little fuzzy sometimes and it might have been better with a fact checked script. In particular the description of certificates in chapter 8 is not I believe entirely accurate so be prepared to do some reading around the subject. Later screen sharing segments are also not very readable (very pixilated) and are focussed towards Windows users.

By Barry Poulson on 2/25/2021

An outstanding and edifying course. Not leading to a specific certification, but tremendous insight into critical topics. Because the course involves video and because Udemy has no mechanism to fully download a lesson before it starts, you have to set the video to a very low density. Perhaps as a result the screens in the last few lessons are unreadable. Still, an outstanding course, entertaining and well explained.

This is a great series of videos on cryptography, hashing, encryption, algorithms, etc. If you were struggling just like me on grasping the concepts behind cryptography then these videos are for you. Mike and Bill make it so easy to understand and in a very fun way. Great course, great material and a lot of fun. Try it you won't regret it!

By Massimo Bastianelli on 12/21/2018

the training removed a lot of fog in my knowledge of this complex topic. I could use the knowledge gained in many discussions that I had afterwards, therefore I appreciated very much the skill that I got from attending. It was definitely not boring, despite the topic thanks to the way they used to explain. Congratulation.

By Gopi Gopalapillai on 10/2/2018

One of the best courses I have ever taken. Explained things in a very easy and unique way to anybody who is really new to this subject. At least, I know how cryptography works and how it's managed in the real world now after taking this course. It's a very confusing subject but thanks to Mike and Bill, I was able to understand the basics very easily. I would like to see many more courses from Mike, he is a great instructor! Gentlemen, Thank you very much!!!

By Jelmer on 9/14/2018

Most of the course content was explained very clearly. However, my expectation of the course was a little bit more technical, so this course didn't fit my expectation, which is not the doing of Mike. The course is well-fit for a first overview, but not much more than that. The style of presenting was very enjoyable, so I would recommend to keep doing that. Thank you for an enjoyable few hours and giving me the motivation to keep looking for a little bit more detail on the subject.

By KW Yap on 6/3/2018

Good course. I think Lecture 2 and Beginning of Lecture 3 where reference to ROT 5 and ROT 10 is off by 1. Lecture 4 slides on DES/3DES has a typo, key size is 56-bit, not 52-bit. Rest of the lectures/episodes with screen recording sessions are very low quality, can't make out any words shown on screen even when playback is selected at 720p.

By Bill Alcorn on 5/8/2018

This course has been better then expected. I have refreshed my understanding of several chipers that I was recently working with and learned some much needed additional information. The instructors were both knowledgeable, captivating, and entertaining I look forward to more conversations by this pair. Well worth the funds to get this course.
