Multi-Agent AI Structural Analysis of the Voynich Manuscript (2026). 33 hypotheses tested, 18 eliminated, 10 validated. 290 files, 146K lines. The manuscript remains undeciphered but its structural architecture is now mapped in unprecedented detail.

Browser-based Vigenère cipher demo — encrypt and decrypt with a repeating key, then recover the key length via Kasiski examination and index of coincidence and solve each column by frequency analysis. Real cryptanalysis. No backends. No simulated math.

LostLanguages AI — where users can uncover secrets of lost civilizations by decoding symbols and simulating forgotten languages

Browser-based Enigma machine demo — full mechanical simulation of rotors, stepping with double-step, plugboard, and reflector, plus the crib-based Bombe break exploiting the no-letter-maps-to-itself flaw. Real wiring tables. No backends. No simulated math.

Browser-based NTRU demo implementing the original 1996 Hoffstein-Pipher-Silverman lattice cryptosystem (EESS#1 v3.3, ees443ep1). Polynomial ring arithmetic from scratch — the lattice scheme that started it all.

Cipher Museum is an open-source, interactive cryptography-history museum where visitors learn ciphers by using them, attacking them, and seeing how each failure shaped modern security.
