TLS / SSL Versions - Part 2 - Practical TLS

In this lesson we'll explore the differences between the many versions of SSL and TLS that have existed over the years.
This lesson is a free lesson from my new course: Practical TLS. This course is a deep dive into SSL and TLS. This SSL Training course is all you need to to fully understand SSL and TLS.
🔐 More details about the course:

🏢 Do you configure or troubleshoot TLS/SSL for work? If so, I'm willing to bet your employer would happily pay for this SSL training. Reach out if you'd like to coordinate an introduction for a bulk license purchase with your company. I'm happy to provide a generous referral bonus =)

Hey Ed, was the TLS 1.3 module already added to your course by 2023?

[@gabygamarra6744]

Every lesson is so clear. You explain these concepts in a way that is easy to understand. Thank you!

[@bharathnaidu107]

You are one of the best teachers that I have ever come across. Thank you ❤️

[@PracticalNetworking]

Thank you for the kind words.

Does AEAD have to do with the introduction of QUIC as a new/3rd transport later protocol that runs over UDP, but establishes the security/encryption arrangement over a single back and forth packet exchange? I just saw a Chris Greer video about QUIC and was left thinking, ' there's a new layer 4 protocol and my instructors haven't even mentioned in the prior 2 years?! WTF?'. It seems like kind of a big deal if we've only had two layer 4 protocols for over 30 years, and there is now a new-ish one.

[@PracticalNetworking]

Good question! Yes, QUIC is the new L4 protocol, a lot of research went in to QUIC and it will likely replace TCP/UDP at some point in the future. As for AEAD... no, QUIC/AEAD are unrelated. It might be that QUIC encryption will use an AEAD cipher, but they are independent concepts. Cheers, Scott!

[@scottspa74]

@@PracticalNetworking damn. I was thinking AEAD in one back and forth seemed to be what QUIC was doing, so I figured it was what allowed QUIC to be as awesome as it is. Clearly there is more I need to understand about why this isn't the case. I'll try to dig into that (as time allows), and totally look forward to any more possible videos digging into AEAD (or QUIC, for that matter). Thanks SO MUCH, Ed, for creating the content you do! 👍 It is so appreciated by so many of us.

3Nov2022 >> what device (((PC/laptop/server/switch/router))) and where do you a tech/engineer go to to check the version or check/verify the TSL???

[@PracticalNetworking]

It isn't easy to check without capturing the packets on the wire or having admin control over the software running TLS. =/

[@subram4534]

Qeep doing sir you are the motivation of me a Cyber Security Aspirant .But try to keep the course avilable on free on youtube rather than paid.

[@zhangsan5564]

good tutorial

[@PracticalNetworking]

Thank you =)

[@shiroryuu2846]

Can mismatch TLS versions on client and server work?

[@PracticalNetworking]

No, the version ties to how/what/when things are encrypted/hashed/etc on the wire... so if they are doing different versions, they will never "understand" each other. It's like different languages.

[@pratikdhame]

I vote for Module 2 - Cryptography

[@PracticalNetworking]

Thanks Pratik. Noted!
