Lightboard Lessons: What is a TLS Cipher Suite?
When a web client (Internet browser) connects to a secure website, the data is encrypted. But, how does all that happen? And, what type of encryption is used? And, how does the Internet browser know what type of encryption the web server wants to use? This is all determined by what is known as a TLS Cipher Suite. In this video, John outlines the components of a TLS Cipher Suite and explains how it all works. Enjoy!

The recent TLS 1.3 protocol mandates that Authenticated Encryption with Associated Data (AEAD) Ciphers be used for bulk encryption. As web servers and browsers transition to using these ciphers, it's important to know what they are and how they work. In this video, John discusses the details of AEAD Ciphers and which ones you can use to implement on your web server.
