In "THE EVOLUTION OF CRYPTOGRAPHY" (itself a ROT13 cipher for the talk's actual title), veteran cryptologist and former NSA Red Team architect Jeff Man takes attendees on a comprehensive journey through the history of secret-keeping, from ancient ciphers to modern digital encryption. Man's central thesis challenges the often-interchangeable use of "encoding" and "encryption" in contemporary discourse, arguing for a return to precise definitions rooted in the foundational texts of cryptography. He highlights that while encoding primarily serves for brevity and speed, true encryption is fundamentally about secrecy and confidentiality.
