When we are online shopping or banking, we want to make sure it is HTTPS, and a green padlock icon is in the address bar. What does HTTPS mean? What is significant about that small green padlock? To answer these two questions, we need to understand SSL certificate and how it works.

After learning from *sunny* I am feeling much *bright* then I was 6 minutes ago.
You are always bright, I believe. I am glad it helped. Happy New Year!
@@sunnyclassroom24 you're good man
I found this tutorial video on the subject the easiest to understand among others. Nice work, sir!
Thank you very much for your nice feedback!
Perfect on 1.25x times speed :D
Lol it really helped!
Thanks!
its really perfect on 1.25x :D
I put 1.5x lol
I play on 2x speed :3
That's what I was searching for!! How the algorithms work themselves because I'm a programmer and I'm trying to learn about HTTPS & SSL....... Thank you, you really helped me a lot rather than other videos on youtube & articles everywhere on google which only tells you that SSL is secure... really they're not any useful but your video is the one that does.
Great Job brother Sunny !! I would highly endorse TH-cam management to reward you for such an excellent presentations !!
Many thanks for your encouragement!
WOW WOW WOW WOW, Excellent Explanation.
No one explained as clear and simplified as you.!!!
Glad you liked it
Great simple explanation. I better listen to this one rather the one where native speaker talks bit more smooth but much less clear. Thanks for great job done!
I have read so much about this but never was it explained so clearly! Thanks so much!
You're so welcome!
Clear and concise explanation with just the right amount of graphics. Thank for your video! But I wish you had elaborated on the specific things a browser looks for in a public key before showing the green padlock.
Mr Sunny really appreciate your works. Not just this video but others also are clear to understand and easy to follow.
Thanks a lot for your time and comment. I appreciate it very much.
This is amazing. Whenever you search for something IT related there is a random asian guy explaining it perfectly. Thank you random asian guy
Thanks for the info, that bit of information at the end of the video about being careful even when on a HTTPS website was Golden, great tip!
thnks this is the first time that I understand the process of HTTPS with such simplicity
Everyone wants to teach should learn from you first.You are the teacher of teachers
Thank you very much for your nice comment.
Thankyou. It was crisp and clear explanation of how the keys are exchanged, specifically demonstrating that the confidentiality is achieved using symmetric key
This is a TRUSTED channel for great explanations! Thanks Sunny!
Really, THE BEST AND CONCISE explanation about https and ssl ever, thank you!!
I haven't seen or read such a clear explanation anywhere... Amazingly Job !
Thank you very much for your encouragement and kind comment!
yaa. share the same feeling. very good clarity
I agree. Thank you Sunny. It is very helpful. I haven't seen any clear explanation anywhere either. Now I am viewing all of your lessons.
I agree.It's more than 5 videos I have watched about Https or SSL, I can say it's yours the most understandable video here.
@@sunnyclassroom24 sunny please make video on Bitcoin too or blockchain.
I never understood this concept until I watched your video, thank you very much.
As easier as it can get....Sir, you rock, henceforth will be your fun!
Thank you very much for your encouragement. I will do my best.
Sunny Brother! I really appreciate your kind efforts, wish you all the Best
Thank you for your time!
Solid overall explanation. Only piece I see missing is when the sending system (client) encrypts the symmetric key. The client will encrypt using the web server's public key plus the client system's private key. The web server then uses the client's public key and the webserver's private key to de-encrypt. If the private key weren't involved than decryption by other system's would be very easy to accomplish, because it would have the algorithm to perform the decryption since it is publicly-held domain knowledge. The private key prevents the reverse engineering of the algorithm to the two prime numbers used in the equation to create the semi-prime needed for asymmetric communications. HTTP/S traffic, aka TLS, is not super complex to understand, however it is comprised of multiple steps. It isn't easily grasped the first few times it is looked at. You did a great job explaining the major steps otherwise. Thank you for putting up the content and sparking people to learn about the world of cryptography! I applaud you sir.
Great point! This was what I was thinking when looking at the video. Anybody could intercept the request and decrypt using the server's public key to find out the symmetric key being sent since the server's public key is...well public lol. Thanks for this comment!
@@abhirammandavilli5802 you're welcome. Kerckhoff's Principle which laid out the case for asymmetric crypto about 100 yrs before it was even considered, great short read.
I know you and your team need to work hard to create such an amusing tutorial.
Best SSL tutorial in TH-cam for sure
the speed is perfect for a Chinese speaker like me😁, thank you sir, your video helping me review the tech details.
thanks sunny ! your videos must be in the first ranks in IT
Thank you very much!
Namaste
Based on domain SSL certificates are classified as three
1. Single Domain - Applicable for only a single domain
2. Wildcard SSL Certificates - Includes subdomains along with the main single domain
3. Multi Domain - Lists multiple domains on one certificate
In terms of strigency of validation these are classified as three
1. Domain validation - This is the least stringent
2. Organization validation - Involves manual vetting process and is more stringent than domain validation
3. Extended validation - Involves full background check of the organization and is most stringent
Thanks
You are great at illustrating by breaking down the concept into simple elements. You should add more videos and perhaps sell your videos on subscription basis. Feel bad to see your great explanations for free
Many thanks for your complimentary and support. Watching and learning from my videos are rewarding to me.
At least enroll your courses in a professional version at Lynda.com :D
The simplicity was so helpful. Thanks!
You are welcome!
Thanks to this video, now even my 5 year old son is able to explain on how data gets encrypted both ways in a client-server communication. You are an awesome teacher, Sir.
BEST VIDEO ON this topic I have ever seen its complete in all respects
Thank you for your time! Check out my other videos please!
the clearest explanation I have ever seen
millions thanks!
Thank you ..weather you are a robot or real man you are great teacher..
Such a clean n precise explanation ever!! Thanks Sunny :)
Clean explanation that anyone could understand, nice
Great learning !!!! you read the pulse of the listener.Great job sir
Many thanks.
Clearly explained with the animation, text and instructor going at a nice speed for newbies like me. Nice 👍
Green padlock means that the servers certificate is trusted, or even more, meets all the criteria to be a trusted certificate. It is the https and a padlock, green or red, that indicates that the communication is encrypted.
That was a fantastic explanation. Thank you! I wish everyone made videos this easy to understand.
Thank you very much.
Very nicely explained. I finally understand how symmetric and asymmetric encryption work together in SSL.
Thanks much for great explanation
This is so well done. Really easy to understand!!!!!!!! Thanks
you so much sir.
This is such a powerful video as difficult topic has been explained so easily and effectively. Great job Sunny!
super good and clear and time-saving explanation. thank you

Well made video! Gives complete information in simple words in a very short time.
Short, simple, clear, amazing!
This is a good one, reaaly good, especially with that CA's public key so detailed
Your explanations and presentations are the best, very clarify !! congrats for your job !!
That's really clear and good explanation, thank you very much!
5:51 - true, but even if you don't have green padlock (cert expired, wrong cert etc) and use https , the traffic is still encrypted.
Thanks for great presentation
Excellent clear cut explanation with simple animation. Thank you very much for doing this, Sir. You are an excellent teacher.

Hi Sunny, very good, clear and useful information. Thanks
Thank you very much for your comment, nice!
Thank you for such clear and precise explanation. Much appreciated.
Verrry good explanation! Thank you so much!
You are Awesome 👌.. Crystal clear explanation !.. thanks alot.
Thank you, i like the way that you explain, it make me understand very fast.
Many thanks.
The HTTPS handshake part is not clear since the symmetric key is not generated by browser but Diffie-Hellman key exchange.
You are correct. The browser (client) uses Diffie-Hellman key exchange.
Sunny Classroom Both the server and the client use a key agreement protocol. One side using it is meaningless. DH is only used in the DH cipher suites.
This is the explanation I was looking for thanks!
Thank you. It's very clear to understand.
The simplest explanation a human can make about SSL on this earth. If there is one simpler than this explanation, it should be by an alien.
Excellent presentation, the best I ever watched.
perfectly simple & clear thankyou sir
Awesome teaching!
thanks a lot.
Really good and simple explanation. thanks
Great explaination woooow , Thank you Mr Sunny

Great explanation. Thank you!
Great demo, thanks
Thanks for watching!
Very well explained Thanks !
You are very welcome!
wow, this was an awesome explanation ! Love from India !
Thanks!
Super explanation, 5:23 typo for public
Sir, explained in a very simple understandable format. Thanks for that. Sir how can we know that the CA is trustworthy ? How can we make it sure that CA will not leak/share the copy of symmetric key sent by us with anyone else other than intended by us. Kindly explain.
what an spectacular video , i understodd very well
you are the best sunny you are too good
Thank you very much for your nice words!
Greatest explanation ever
Really easy to follow. Thanks.
"HTTTTTTTTTTPS"
Lol. Jk, thank you for the great explanation !
