TLS 1.3 - What Changes? What stays the same?

TLS 1.3 was released in 2018 with RFC 8446 -- a full 10 years after the version prior (TLS 1.2, RFC 5246). TLS 1.3 introduced many changes to TLS and how secure communication works. TLS 1.3 was in fact a major overhaul of how SSL works.

Despite all the changes, not everything in TLS 1.3 is different -- a lot stays the same. In this video we outline what remains the same, and list 20 different significant changes in TLS 1.3.

This lesson serves as an introduction to the upcoming lessons in the series, where each difference will be discussed in more detail.

👉 This is a sample lesson from my SSL & TLS deep dive course: Practical TLS.

If your referral leads to live training engagement, I'll buy you an iPad (or tablet of similar value of your choice)

I absolutely love the fact that your updating your SSL/TLS course to include TLS 1.3! Not everyone would do that especially with how much time and effort you put into making each and every video. Thank you again Ed and best of luck to everyone.

[Don-Carillo]

Cheers Ed. ive never ever come across anyone who can explain such complex things like TLS so well in your videos . Absolute natural. hope you keep growing, Definately deserve it . Looking forward to the TLS 1.3 vids, keep them coming :)

[sharathugranad]

So far the best channel on Youtube to understand in detail about SSL/TLS, encryption, hashing and many more concepts of CIA, which is the basics for Security. Thanks you for making the concepts to understand in a simple way with great visuals. Please continue to share such content for all the security enthusiasts out there. Thank you Ed.

I am absolutely loving this course and am currently in Module 6. I highly recommend this full course as the material is presented thoroughly and with enough modularity that you can easily go back and review concepts if needed.

I have been waiting for the 1.3 continuation of this course. So happy it is happening.

This is actual pratical networking, Thank you Ed!!

[emmanueligbokwe]

Recently had to watch some of your videos to understand TLS 1.2 and it’s handshake. Needed that to be able to fix a vulnerability shown by the infosec team. Would be great to be part of those enrolled to the practical course. Wishing me luck

[vlgermanov]

As always a great video! 👍 Thanks for sharing it with the community!
