TLS 1.3 Cipher Suites - Here is what CHANGES!
Practical Networking

If you’ve been in the Network Engineering career field for any small amount of time, then you’ve probably been frustrated at how difficult it was to find articles and videos that were reliable, thorough, and understandable. You found articles that were very entry level, that perhaps gave simple definitions but did not communicate enough to explain how technologies actually worked. You found articles that were overly detailed, that went into so much minutia that the original point would be lost. The intent of the blog and video channel is to bridge that gap — providing the happy, practical medium between overly simplistic and overly detailed. PracNet teaches in a manner that is accessible, easy to learn, and easy to pass on. By presenting complex technology simply, PracNet provides practical, immediately applicable, knowledge of the Network Engineering industry.

Video Description
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. 👉 This is a sample lesson from my SSL & TLS deep dive course: Practical TLS. https://pracnet.net/tls 🔑 More free lessons from the course: https://www.youtube.com/playlist?list=PLIFyRwBY_4bTwRX__Zn4-letrtpSj1mzY 🏢 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. If your referral leads to live training engagement, I'll buy you an iPad (or tablet of similar value of your choice) 💬 Join Practical Networking Discord https://pracnet.net/discord 00:00 - What is a Cipher Suite? 00:56 - Old protocols are no longer supported 02:32 - Cipher Suites are Simpler in TLS 1.3 04:30 - Orthogonal Cipher Suite choices 05:28 - Fewer Cipher Suites in TLS 1.3 07:20 - All TLS 1.3 Ciphers are AEAD - Authenticated Encryption with Associated Data 10:18 - TLS 1.3 mandates Forward Secrecy 12:29 - No more custom DH Groups 15:24 - Key Points - Changes in TLS 1.3 related to Cipher Suites 16:07 - Want more?
