TLS 1.3 Cipher Suites - Here is what CHANGES!
Vložit
- čas přidán 2. 06. 2024
- A Cipher suite is a selection of one specific protocol for four security services: Key Exchange, Authentication, Symmetric Encryption, and Hashing. In TLS 1.2 and prior, a single Cipher Suite selected a protocol for all four of these... in TLS 1.3, a Cipher Suite changes to only specify a protocol for two of these: Symmetric Encryption and Hashing.
Here is what a Cipher Suite looks like in TLS 1.3:
TLS_AES_128_GCM_SHA256
Here is what they looked like in TLS 1.2 and prior:
TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
Beyond that there are many other changes to how Cipher Suites work in TLS 1.3. This video unpacks 6 significant changes to TLS 1.3, all of which relate to Cipher Suites.

Giveaway comment, I love to learn networking from you, your video on subnetting under 60 second is truly amazing !!!!
It's honestly unbelievable how much information you manage to convey in such a short amount of time!
If you’re looking to learn TLS… Practical Networking is where to start! I’ve learned tremendous amount from Ed and his videos! He’s an excellent teacher and his illustrations are always great!!! I’ve always struggled in the classroom! Ed makes learning easy for me! Thanks Ed!!!!
Ha ! Is always fun to listen to Ed who always makes complex subjects easy to understand. I have to revisit the course to take advantage of all the changes you talk about. but am happy TLS1.3 have simpler ciphers than previous because any time i get a ticket from vulnerability team about weak/SSL/TLS ciphers i have to revisit my class notes to see the ciphers which i have to take out and which ones i have to include. Great video Ed! Thank you again.
You're welcome!
These lessons are top tier in my opinion. This teaching style suits me perfectly. I used what I learned from your practical networking series yesterday while reviewing some Wireshark captures at work. I could understand them better because of that series, thank you!
Thanks again, very rare to find a video with such detailed content
If you liked this level of detail, you'll love the full course. It goes much, _much_ more detail than this =)
Very well constructed videos and tutorials. Really easy to follow.
Will need to go back to this a few times, thank you for these.
Thanks for the clear and detailed videos! Great work :)
Great video! I like how you explain things in a way that actually shows you want us to understand
I clicked the thumbs up button 11 times, sadly I cant upvote your video more than once. Thank you
This is brilliant
your way of presentation and simplifying information is amazing, I like it so much ✨✨✨⭐
great content as usual :), watch his other courses if you havent already. I have learnt loads from them

@@PracticalNetworking Thanks for the TLS 1.3 course!
Thank you for this. As someone working for a CA any explanation is a big help. Do you mind if i post this in Linkedin?
Good video
You're the best
Hi Bro, I would appreciate if you could do session about STUN,TURN and ICE
I adore your OSPF course on Udemy. Is the course available on Udemy?
Glad you enjoyed the ospf course!
At this time I have no plans to put the TLS course on Udemy.
Hello, have a good time
Please make a video about CDN
Thank You.
