Understanding Secret Keys: A Simple Explanation

In this video, we formally define a term used throughout cryptography: Keys & Secret Keys. Nearly every operation in Cryptography makes use of these keys, so it makes sense to spend a few minutes discussing them. // CHAPTERS // 0:00 - What are Secret Keys? 0:36 - Key Sizes and Bits 1:59 - All keys are susceptible to brute force 2:34 - Why do we use Secret Keys in Cryptography? 3:41 - Symmetric Keys and Asymmetric Keys // FULL SERIES - Cryptography Essentials // This video is part of a 16-part series covering the essentials of modern Cryptography.
