Histocrypt 2019 program

The program for the International Conference on Historical Cryptology 2019 has been posted.

For me the more interesting presentations (based on the titles) are:

4. Eugen Antal, Pavol Zajac and Otokar Grošek: Cryptology in the Slovak State During WWII
5. Dermot Turing: The Typex Scare of 1943
6. George Lasry: A Practical Meet-in-the-Middle Attack on SIGABA

I hope they post their proceedings at their site like last year.

In the essays French Hagelin cipher machines and The French War Ministry’s FLD code I added information from the Bulletin de l’ARCSIarticles  Essai d'historique du Chiffre’. Specifically in the paragraphs ‘French Army codes and ciphers’ and ‘French military codes and the Battle of France’.
