Studying original cipher keys constructed throughout history gives important in-sights into encryption methods and cipher systems. We can study the type of encryp-tion used, the code structure and their cor-responding plaintext entities, be it letters, morphemes, words, or named entities. The insights can lead us to better decryption methods, and the understanding of the de-velopment of historical ciphers. In this pa-per, we present a tool for automatic key structure extraction that describes the sym-bol system and the code structure along with the encoded plaintext features and the mapping between the two. The tool is aimed at the empirical study of historical keys given transcribed keys.
