The Secrets of Cryptography

Explore the world of cryptography in this 55-minute conference talk from PHP UK Conference 2018. Delve into the challenges faced by Alice and Bob as they attempt to communicate securely in a hostile environment where Eve eavesdrops and Mallory manipulates messages. Begin with a brief overview of historic codes and ciphers before diving into modern cryptographic techniques. Learn to distinguish between block ciphers and stream ciphers, and gain insights into the mathematical foundations of public key cryptography. Discover how secure communication is achieved in the face of potential interception and message alteration.
