Overview of 2017

2017 turned out to be a very productive year. During 2017 I copied material from government archives in Germany, US and UK, I received a lot of material from the NSA’s freedom of information act office and I also benefitted from the release of interesting files that were uploaded to the NSA and CIA FOIA websites.

Some of my friends also shared important reports with me and I did my best to repay them by giving them some of my material.

1). Regarding original essays, I wrote the following:

2). I also added new information and pics in various older essays:

The American M-209 cipher machine (I added notes and information from various sources)

Wartime exploitation of Turkish codes by Axis and Allied powers (I added decoded Turkish diplomatic messages)

Soviet partisan codes and KONA 6 (I added information from the TICOM report I-26)

The Japanese FUJI diplomatic cipher 1941-43 (I rewrote parts and added information from TICOM I-181)

Japanese codebreakers of WWII (I added new links and uploaded a PDF file with the decoded US diplomatic messages)

Svetova Revoluce and the codes of the Czechoslovak resistance (I added information from the report ‘Dopady lúštenia šifrovacieho systému čs. londýnskeho MNO z rokov 1940-1945 na domáci odboj’ and the essay ‘STP cipher of the Czechoslovak in-exile Ministry of Defence in London during WWII’)

Decoding Prime Minister Chamberlain’s messages (I added information from TICOM DF-241 and from ‘British Intelligence in the Second World War- volume 2’)

Soviet cipher teleprinters of WWII (I added information from the TICOM reports DF-240 and DF-241)

Compromise of Soviet codes in WWII (I rewrote parts and added information from various sources)

3). I uploaded the following files and links:

  1. Thanks Chris for all that great reading. I especially enjoyed all the information on cryptography, your hunt for codebreakers, equipment and units. Always great to come here.

    Have a great 2018 with many new documents!
