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

[@CraigForant]

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!

[@kalkalasch]

troof

[@Viatto]

Hugely appreciate your kind words Craig. I frequently try different styles and never know what “works.” :-)

[@nurjehankarim9787]

You are amazing

[@banerjeearkajit]

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

[@almasabdrazak5089]

"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

[@matrix9046]

Exactly Same here 🤌

[@JorgeAlmazan]

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

[@transformer889]

Good, now you can explain it to the rest of us.

[@danieltnaves]

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

[@pootchie28]

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!!

[@1200Moises]

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

[@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!

[@asemmoqbel982]

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.

[@lingaiahdanda6214]

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

[@ajaygulani3086]

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!

[@MinhLêNguyễnQuang-k4z]

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

[@chittranjankumar5769]

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

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👍 🙌

[@antonioskokiantonis7051]

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!

[@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!!!

[@mathewkargarzadeh3158]

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

[@base4our]

At last, a clear explanation of SSL/TLS! Thanks for this!

[@damokerbs5856]

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

[@tonynunez6539]

Great explanation of a process that even most experienced IT professionals in the DOD don't even understand. I am constantly struggling to explain the process to them.

[@ashwanthbalajir5153]

That's really heavy. But you know this is the video where I have understood the process in a clear manner.

[@mk325ef]

"Wait a second!"..."I'm going to put this to bed right now...".. Awesome video. Thanks for trying to simplify it.

[@franchise2570]

This is awesome, you did an excellent job in explaining the concept! Bravo to you sir. 🙂

[@EvelioOpenMat]

Brother I love you........I am studying for security plus and I understand alot but you just made everything click together.

[@xlugerxD]

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

[@victorramiso4309]

Its awesome how fast you speak when you get all excited when explaining and then i get all hyped as well love all your vids

[@forwardfocus8649]

This is a brilliant, informative, talented piece of teaching. I'm putting it on my twitter account. I agree with Craig that the engagement is amazing. This is how you want to teach using electronic mediums.

[@027vishal]

Thank you Jeremy, One of the best explanation I have ever seen on HTTPS

[@syedamin6690]

This is the best video on the internet on this topic.

[@manuelaraica3964]

Thanks Jeremy! Always love that passion that you bring sharing the knowledge.

[@1snico1]

Mate, I really don't comment on youtube very often but I need to say this - absolutely brilliant video. Your method of explaining and teaching is better than virtually anything I've ever seen, both online or in actual courses (and I've been to dozens). Certificates are something that have remained as a bit of a black hole for me in my career and finding a video like this that so succinctly re-enforces everything in my head is just amazing. Definitely subscribing.

[@ranti013]

one of the best videos on the internet. Thank You.

[@jiangfrank6283]

this is best , not one of the best explanation on SSL/TLS which I have been seen , Great !!!

[@oebelus]

The best explanation ever! Thank you so much for this video.

[@boysweetpotato6575]

man you're a legend! you're the one who made networking understandable for me during my college days and now you still rockin and im still learning from you. such good stuff! Edit: Helped me aced my job application last week! im really happy i bumped into this content! Thanks Jeremy, All the best!

[@garryn123]

Hilariously serious...very engaging. You're a bit of a 'nut case' with this and I mean that in the nicest way - keep up the good work! 👍😆

[@aliyousef9580]

Huge effort , thanks jeremy ,keep watching this video and cant get enogh .. Many thanks from syria.

[@EBay_Dev]

after 2 3 years, finally I got it and I got it right :)) thank you so much

[@aimtiaz_]

Fantastic video. One of the best that describes SSL & HTTPS out there. Would be great if you can do a video on the intricacies of certificates - root, intermediate, leaf etc.

[@egemendemirbek]

Really appreciate your efforts... I'm looking forward to take and complete the entire series ... please don't be late :)

[@josephbais7463]

The best ever https explanation.

[@pierrekosmas2405]

[@GauravSingh-fu3dn]

Loved the pen 🖊 and paper 📄. Nice explanation 😊

Did a great job at explaining a complex concept. Would give 2 thumbs up if I could!

[@kalkalasch]

you can't, you can do only 1

[@miaturner5403]

I finally understand this concept. Thank you!!

[@travelwalk539]

I found this video very helpful and it helped me to understand the whole HTTPS protocol. Great work done!

[@timurius1988]

Thanks for clear explanation! Good job!

[@Viatto]

Glad it was helpful!

[@agustinzago9180]

If the CA encrypt their signature with their private key and u need their public key to decript it. Wouldnt that permit a hacker to decript the CA signature in between the web browser and the server? Since the public key is on public demand?

[@mrscbw1]

Awesome explanation.. subscribed!

[@samdagar4447]

Brilliant mate!

brilliant!

This is gold!

[@kalkalasch]

Jeremy for presidnet.

[@clementduval3917]

In the end, the true power of it lies in the fact that only the server can decrypt the session key (for all traffic encryption) , since it owns the private key . That is why a hacker in between wouldn't be able to eavesdrop, since they wouldn't be able to decrypt the session key, that was used to encrypt the Public Key. They key technology here is the "asymmetric Encryption", the fact that encryption made with one key can only be decrypted with a different key. Please tell me if I understood well
