greshko/naibbe-cipher: Python implementations of the Naibbe cipher and Voynichesque, decryption script and figure data
Michael A. Greshko, 2025.
What it's used for here
The cipher's published tables (references/naibbe_tables.csv: 414 cells, six tables of unigram, prefix and suffix glyph strings for 23 letters), the encryption parameters (52-card deck weights 20/8/8/8/4/4, standard respacing 17/36, bigram re-draw when prefix+suffix spells a unigram type) and the Latin and Italian sample plaintexts (Pliny NH 16, Divina Commedia). Modified MIT licence; publications using it must cite Greshko 2025. Used as the source of the tables and plaintexts for the Naibbe simulation and key search.
