Keynote: Crypto means Cryptography!
summary
A brisk tour from 4,000‑year‑old Egyptian secret glyphs and the scytale to Enigma and modern submarine cables shows how cryptography protects web traffic, devices and backups; landing sites let GCHQ/NSA tap hundreds of terabits and Snowden forces a jump from ~25% to ~90% HTTPS. Examples: LavaBit was compelled to hand keys, RSA contests: a 430‑bit semi‑prime broken 1996, 663‑bit in 2005 (75 core‑years), 829‑bit in 2020 (2,700 core‑years). Emphasis on forward secrecy and the push to quantum resistant primitives before quantum factorization makes current RSA practical.
