What are SSL/TLS Certificates? Why do we Need them? and How do they Work?

This guy's voice is perfect for teaching. So relaxing and calming :)

love the knowledge you have shared, it was extremely useful and it had a bit of humor in it to make the watcher feel engaged

Thanks a lot for this video!

Your video was amazing. I understood it all but got a little confused at the end where the client has to then verify the CA's signature on the servers public certificate and then eventually makes its way back to the root certificate. I'm not sure I need to know either but still understanding the rest was important i.e. going from RSA to then signed certificates.

Thank you Hussein for the great explanation. Finallyyyy I got the concept

xD u made my day man, thanks 🤣

too long and horibly explained

Nice explanation but i didn't how server verify itself to CA since server is sending public key to CA and Karen might be inbetween server and CA and Karen might send her public key instead of servers public key ? Digital signature by sending private key of server will verify that its a legitimate server....

you really hate Karen, lol

too many fluffs.

Thank you

Not terrible but I had to bail after the 1 trillionth ‘right??’

As you mentioned in the video the public key of a server encrypted by CA's private .So the client who already have root certificate which include CA's public key can decrypt the certificate send by the server . Is it possible that publick key can decrypt the data which was encrypted by private key ?

Man, you are genius!! I’ve spent almost an hour checking other videos about ssl but couldn’t understand it completely. But the way you explain it, it’s super clear now. Thanks a lot

Why don't they just send a PDF instead of making me go through all 7 levels of HELL ?

great job but please leave KAREN out of this 😆🤣

stop saying right

This is awesome, thank you. The visuals were helpful

Thank you! Just what I was looking for :)

Your free content is also great like your paid one

This explanation was exactly I was looking for. Thank you!

This is a great video. Understood everything!!

Am I the only one who find it is very confusing?😅😅😅

Thank you Hussein, I am an IT student and this video helped me so much !

😂 Keep going explaining things this way

Thanks!

I understood public key cryptography, but was looking for how these certificates are exchanged. This explanation was spot on, thank you so much.

Hi Hussein, i am confuse since i am new at this and i already made my server secure with ssh with putty and what i don't understand is does making a certificate replace replace my ssh keys with the certificates keys from certbot? I have a hard time setting up my vps with 3 domains under a single wildcard certificate!

you should make nft with those beautifull drawings of yours. Thanks a lot for the explaination

The way this video was made is exemplatory for indian work culture. Quick and ugly sketches, no structure, wasted time by having to switch between colors all the time. It would not have been that much more work to just add some nice graphics and edit arrows between them, but he just had to go with the absolute jankiest option.

It’s Eve, not Karen. But since Eve is acting like a Karen then Karen is acceptable.
And I just acted like a Karen, I realize.

ok, I understand ...... they make very complicated communication between public computers and servers ...just to make a money ...from nothing.

Me on tinder- "Take my public key beautiful. Take it."

You usually publish very good content but this lesson is very messy :) Too much "playing" with the chalkboard...not so easy to follow this lesson.

Too much distraction of toggle on and off. Otherwise great explaination.

Too many steps for me

this looks a lot like the blockchain

Thank you for your video. I have some questions:
- Does the server send the certificate for every session?
- Does the server asks the CA for a certificate for every session? Or does this happen only once?
- Can't Karen get her certificate signed by a CA using the public key of the server? Because she has access to it since it is just send over?
- Do I have a root certificate on my PC for every website? And does it expire? I've never had to renew one? How does this work?

Tq bro I love the way u explain the things it is so interesting..

Hey Hussein... can you come up with a video on the details of the certificate itself... for example whats an Authority Key identifier, SCT List etc ... guaranteed atleast 5-10 views from my end and a like

if the certificate is my Apple ID thats considered private right ?

This has just made me more confused...

Wish @ 193K subs flow diagrams were drawn a little better. Also other vids from Hussein are better (less cocky).

Thanks alot for the content youre puttting out man. Really appreciate it captain
.

totally awesome !!!!

I've just watched this video ten times just to enjoy the stuff. Really cool way of teaching.

Excellent Concept..
