Museum Map
13 halls, the Foundations Annex, 172 exhibits — one continuous story: how humanity learned to keep secrets
Suggested route: Start in Hall I and follow the historical connections, then visit the Foundations Annex for the mathematics. The halls cover overlapping traditions and different security goals, rather than one inevitable path from simple ciphers to a single “unbreakable” system.
Trust Labels
Cipher and protocol exhibits carry one of four labels indicating their modern security status. People, places, institutions, principles, fiction, cultural exhibits, and mathematical foundations carry no cipher trust label. Click a label on any exhibit to return here.
Cryptographically broken — historically important but unsafe to use today.
Obsolete or historical system; notes distinguish cryptanalysis from capture or other operational compromise.
A didactic construction for learning cryptographic concepts, not for security.
Still considered secure when used correctly with modern key handling.

Complete Cipher Index
The 152 cipher and cultural exhibits plus 3 research case studies are organized below; the 17-exhibit annex remains at §141–157.

Research case studies: what was actually attacked?
UA-8295: altered firmware and forensic evidence · SoDark: eight-round radio linking protection · NFC: authentication, configuration and counterfeit hardware
Compare GPU search, GPRS faults and conditional-linear DES. Each result identifies the target, attacker access and limits of the evidence.
