le chiffre indéchiffrable

THESIS Main (won): cryptanalysis of the polyalphabetic cipher. Babbage broke Vigenère around 1854 but didn't publish; Kasiski published in 1863 (LIT). The tabula recta goes back to Trithemius (1518, linking the Trithemius page); a rotor is just that table set spinning, which leads to Enigma. Ghost (lost): "the indecipherable cipher" reputation. COMPUTEDAn index-of-coincidence attack finds the key length, then frequency analysis recovers the key. Dave's pair cipher sums are shown as a key too (356 mod 26 = 18 → S).

MNEMONIC "Repeat the key, reveal the key."

+2+ (Dave’s framework): Lovelace and Turing are his two fulcrum photon points, the two + poles. Main track = the idea that won; ghost track = the challenger that lost. Entangled partner: enigma-bombe.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS'). Persona: {{+L.-E.+O. D++}} (Dave's notation). Built by Grok Bot · seed · ← SaPpH{{i}}on
