How HTTPS Works (...and SSL/TLS too)

In reality, there is NO SUCH THING as HTTPS, just HTTP with SSL/TLS added to it! This video is a "slice" from the upcoming @comptiaexplore Security+ series I'm building with @NetworkChuck and @davidbombal. I would love to hear what you think about the new style!

00:00 - Introduction
00:20 - Fundamentals of HTTP Communication
03:30 - Where SSL came from
04:30 - The difference between SSL and TLS
06:02 - How SSL/TLS works
07:02 - What is a Trusted CA?
10:00 - The three major pieces of a PKI Security Certificate (asymmetric encryption)
11:45 - What happens when a client visits an HTTPS site
12:10 - Generating a session key (symmetric encryption)
15:00 - Why SSL/TLS is so important!
16:05 - Why the CA Signature is important

Jeremy....I don't think many people realize the significance of the short and subtle pauses when you switch from the drawing to looking into the camera to talk to us. This style of teaching is incredibly engaging and allows the viewer's mind to refocus and absorb what they are hearing. Love the usage of different techniques and methods. Please keep doing what you are doing. You have a superhuman ability to engage your audience and break down the most difficult of subjects in the most sensible way. You inspire me on every product demo and training session I present to my clients. I would love for you to create a series on how to be a better presenter!

Best explanation of SSL/TLS I’ve every seen. Great job Jeremy!

[banerjeearkajit]

I have never seen anyone explain this concept so flawlessly. Appreciate you so much, Jeremy.

"client encrypt session key using server's public key" that's the sentence I was looking for, it was so confusing reading other blogs saying that encryption starts as asymmetric and then switches to symmetric, this single sentence makes it clear how it works, thanks a lot

[MauroEnding]

how many knowledgeable people we may have in the world if we all have someone like him teaching this way! wow! 19.38 mins being more productive than toons of classes I have been to! hands down to you!

[danieltnaves]

Excellent video... The clarification, in the end, about how the signature is verified and how the browser does that was perfect! Thanks!

Watching you teach anything is like binge watching some very addictive TV show! When this video finished I felt the almost 20min just go by so quickly, and leaving me wanting to watch the next video right away. This was so engaging!

I always thought I knew SSL/TLS, but as you mentioned there were certain things where pieces of puzzle were just missing and after watching this video I have those pieces!
And I have watched you videos on CBT Nuggets for my CCNA training and you managed to break down something, that for me was so complex for me to understand by other means (reading books, other training courses) where I thought there is no way I will understand this networking stuff, to explaining it in such a way that anyone can relate to and then really understand it!
So thank you for all the teaching that you do!

Software engineer here. This is the best explanation I have of ssl/tls works. Thank you!

One year later and I just watch this now.. I can't say how much helpful this video and the information is delivered so smooth especially the cryptography part.. Thank you jermey and the video is saved for future needs.

[pootchie]

Iam where Iam now because of you. 2015 I decided career switch, 30 days of career break just watching online - Jeremy's videos on CCNA, after 2 months landed a job. Thanks so much!!

Your effort will not go waste the way you are tried to feed and inculcate the content in viewers mind. Hats off to you.

[RockHopper]

I've yet to find a better teacher than Jeremy who can take any subject and present in a way that anyone can understand. Top work, and thanks👍 🙌

[antonioskokiantonis]

I've seen a very passionate guy trying to teach fundamentals. Really appreciated and subscribed of course!

[fhfolbf]

Sir, your passion towards the topic simply gets us hooked in no time and make us want to stay on till the end. Kudos to you for all the efforts!

[lingaiahdanda]

you are an addiction jeremy. your method of teaching is unique. Thank you!

[mathewkargarzadeh]

Thank you fro putting such a concerted efforts explaining this convoluted subject ( SSL/TLS ) in plain English. appreciated for sharing your working knowledge. Mat.

[MinhLêNguyễnQuang-kz]

I am absolutely clear how ssl works. Tks for your spending time!

[xlugerxD]

I don't usually comment, but you are awesome... from your teaching methods to your charisma, keep the good work! Cheers!

[MichaelWalmsleyJr]

Fantastic explanation for someone like me who has been doing front end development for years, but never fully understand everything that was going on with https. Definitely filled in a few holes in my understanding of the process! Thanks!!!

[damokerbs]

That's some damn good teaching here I wished I brought popcorn with me. Thank you for the great content !
