SSL Complete Guide 2021: HTTP to HTTPS - Diffie Hellman Overview

The video tutorial introduces the Diffie-Hellman algorithm, developed in 1976, which enables secure key generation over insecure public connections. It explains how the algorithm works using one-way functions, ensuring that keys generated on both sides of a connection cannot be replicated by others. The tutorial also discusses the application of this algorithm in the TLS protocol and mentions its variants, including those using elliptic curve cryptography.
