A complete overview of SSL/TLS and its cryptographic system

This is a very thorough video to tell you everything about SSL/TLS and its underlying cryptographic system.

What we will learn:
- What is SSL/TLS?
- What really happens during a TLS handshake?
- How do client and server exchange secret keys?
- What cryptographic algorithms are used by TLS to protect the data?
- How Diffie-Hellman algorithm works?
- Why do we need a digital certificate?
- Why does it need to be signed by a certificate authority?
- What is a digital signature? How is it generated?
- What perfect forward secrecy means?
- How AEAD, MAC, HKDF, 0-RTT works?
- What is Elliptic-Curve cryptography?
- What's new in TLS 1.3 compared to TLS 1.2?

Just wanted to take a minute to thank you for posting this. It may just well be the most comprehensive breakdown I've found concerning the differences between TLS 1.2 and 1.3. I've watched it maybe 3 or 4 times and it's just as great each time.

You are an excellent teacher. Discovering your channel is the best thing that has happened to me. I'm currently taking the go master backend course. Thank you so much.

This may be one of the best teaching videos on any subject I've seen on YouTube, and definitely one of the best videos on HTTPS and SSL and TLS. If you already have a background in web application development and web application security, the concepts in the video are well explained and the diagrams and graphics enhance the explanation. If you are having problems understanding the content of the video, I'd suggest getting a basic understanding of web application security first.

Great job! :)

This channel is an absolute goldmine. I hope you keep making videos to help everyone learn these complicated topics.

By far the most comprehensive and easy to understand video on TLS I have come across. Keep up the great work!!

[mobilequickie]

WOW. This is an amazing video explaining TLS in a detailed consumable way. Really, really awesome stuff.

[acm...]

Exceptional content! The attention to detail to cover each aspect made it easy to visualize what would otherwise be a difficult topic to follow.

[navisachar]

Fantastic video. Not just educational, but very well structured and explained - useful for security professionals to use as a benchmark for explaining TLS. Keep up the good work.

Great tutorial. Working is ssl/tls everyday and didn't know the basics. Thanks

[yujiaqiao]

Best explanation about TLS I've ever seen. Thanks for your great work.

[silvertranc]

Great balance between details and topic coverage. Awesome resource!

[PuneetKumar-nzst]

This is one of the most awesome video I have ever seen.. All those terminologies I have been reading.. HKDF, AEAD etc etc.. never made sense to me until now!!!

[Khiem-wnwp]

Excellent video. I've not quite understood some cryptography concepts for a long time until I watched this video. Very thorough. Keep going man!

[Bentleys-Mom]

Wow. This was by far the most awesome vid I have ever seen. I am completely new to tech and I feel like I have a good grasp on how encryption works now. You are an amazing teacher.

This is my first comment ever on the YouTube, after watching millions of videos😁

Two words only for this video: *Simply Awesome*😎
Subscribed your channel immediately, while watching this video. Hope you continue creating amazing content for the geeks.👍

Very nice and video I have been looking for many years, found it now that has so many details of the key/message handshake between the client and the server which I am looking for. I am not currently working on SSL/TLS but was very curious to know how the key exchange is done and what is signing, what is a certificate etc.. One word it is excellent! But I need to watch this video many time to obsorb all the concepts used. Will keep watching your similar videos again.

[alicetran]

Thank you for the great video, easy to understand, well structure and detail enough.

[kaiorafael]

by far the most well explained tutorial about TLS. So, when studying TLS and OpenSSL library and all the crazy name protocols ciphers as TLS_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256, so on so forth... Now it makes lots of sense! If in the future you remake this video, please bringing an example like OpenSSL ciphers would be the killer master super ultra mega power video tutorial :D You have got a subscriber. Thank you for your work.

[lateralot]

Truly a brilliant explanation of TLS. I'm much obliged to him. thanks a ton.
