Jean-François BOUCHAUDY's Crypto page


For several years I have been passionate about cryptography. Particularly interested in cipher machines. Perhaps that my stint in the army as cipher clerk is one reason. I have could for almost a year handle CX-52s as well as CD-57s and Tarek.

I am not only fascinated by their functioning but also by their cryptanalysis. I have made several small programs in this sense that you will not find on this site as they were written too quickly.

On this site you will find some cipher machine simulators. They all work (with few exceptions) in text mode. Most were written in Python and therefore can run on any system.
