Studying original cipher keys constructed throughout history gives important insights into encryption methods and cipher systems.We can study the type of encryption used, the code structure and their corresponding plaintext entities, be it letters, morphemes, words, or named entities.The insights can lead us to better decryption methods, and the understanding of the development of historical ciphers.In this paper, we present a tool for automatic key structure extraction that describes the symbol 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.
