Ciphers of Henry IV's Representative in Germany

I uploaded a new article "Catalogue of Ciphers Related to Jacques Bongars in BnF fr.7125-7132". This series in the French archives includes many letters in cipher as well as original ciphers. (I came to know of this series by BnF's video at YouTube.)

As a by product, I made an addition in "Code, Cipher, Nomenclator -- Notes on Terms in Cryptology" to mention that there is an instance where a list of code words without any substitution alphabet is called "chifre".

  1. As a corollary to this, I uploaded "Development of Ciphers under Henry IV of France: A Case of Jacques Bongars: 1590-1611" at Academia.edu). This version focuses on ciphers used between Bongars and the court and provides preliminary observations in an attempt to contextualize them.
