A few days ago, I asked this subreddit if there was interest in a free live webinar discussing TLS 1.3 and how it differs from previous versions of SSL/TLS. The response was overwhelmingly positive, so I'm offering the webinar Thursday 12/15/2022 at 2:30p PST / 5:30p EST.

TLS 1.3 and how it differs from previous versions of SSL and TLS

Thursday :: 12/15/2022 :: 02:30p PST / 05:30p EST

• Duration: 2 hours
• Agenda:
  • 60-75~ minutes of lecture, with 3 breaks for Q&A
  • followed by free for all Q&A on anything TLS/SSL related for the remainder of the session.

Topics I plan to cover:

• Old protocols no longer supported
• Simpler Cipher Suites
• Fewer Cipher Suites
• All TLS 1.3 Ciphers are AEAD
• Forward Secrecy
• Removed Custom DH Groups
• Shorter Handshake (One Round Trip)
• Most of the Handshake is Encrypted
• Client Certificate is Encrypted
• Many, Many more Session Keys
• Middleboxes - what they are, how they inhibited smooth TLS 1.3 transition

For each topic I plan to describe how a feature worked in TLS 1.2 and prior, how it was broken, and how TLS 1.3 improved it.

If you're apprehensive about registering and providing your email address, no worries, I understand. This link should take you directly to the watch page (a zoom invite link will pop up when the countdown expires).

Q: Will the session be recorded?

Yes. It will be recorded and made available to those who register. If you want the replay you'll have to register.

Q: Will there be more sessions?

Sure. I'll do more, and on other topics, if the subredddit wants and as long as it doesn't violate any subreddit policies. I asked the mods specifically about this one and got no response... went ahead scheduled hoping the positive reception in the initial request was enough for at least this session.
