SSL/TLS handshake Protocol

Please support my channel by becoming a Sunny Classroom member. Your support is much appreciated.

What protocol is used between a web server and its clients to establish trust? How do they negotiate and share the secret key? During the handshake process, how public key encryption algorithm is used and how private key encryption is used? In this video, you would find all these answers.

I put your video on 1, 25X speed, and it sounds even better!

Very detailed explained! Thank you for the video. On step 2, the server's digital certificate IS the server's public key, signed by the CA. It brings a lot of confusion to a lot of people not being told clearly that a certificate is just a public key whose ownership has been certified by a CA. So you can basically say that the certificate is what is used to encrypt the client key, once the CA signing it has been verified.

Great Job Sunny!!


I can't believe how many videos I had to watch until someone actually explained this concept. Every other video was a complete waste of time. I really enjoyed the clear details and breakdown of the process.

3 years later and these videos are still great learning and reference material. Thanks very much 👍🏾

Clear; Concise; Comprehensible!
Well Done and Thank You for breaking SSL/TLS, high-level essentials down so amicably. Will check out your other Classroom topics.
Keep it going!

Very helpful! I was confused by the way my textbook worded this, but this explanation cleared it up for me!

[shankaraklod]

Thank you for making concept so crystal clear

[moorthyrekapalli]

Thank you very much for explaining in a way that is easy to understand. Watched several videos before this and it was still confusing. Glad that I came across your video. Thank you for your contributions.

It wasn't until I stumbled upon your channel have these things become all clear to me. I've been not able to understand how certificate, digital signature, and SSL, HTTPS and the likes works for years. Too many videos articles go into details with the missing pieces at the high-level or not explaining the how at all. Now that I understand it, I can see how horrible many of these materials are at explaining things. Thank you so much. Now I can read other detailed articles with much more clarity. Thanks again!

Sunny, you've helped me with a lot of my cryptography assignments. thanks a ton!

[Forky]

Thank you for your very synthesized videos, very very useful. Master class in 5 minutes about the basic concept of SSL you smashed it!

[allanlimaverde]

That's one of the best explanations I've seen. Thank you and congrats!

This is too good, amazing how simple it is

[TheZiZaZo]

Thank you for the video! I appreciate you taking your time and getting in depth about this! A lot of videos are too vague/general for my liking.
