Upcoming essays

After finally receiving the documents I was waiting for I can write a detailed essay about the compromise of Soviet codes in WWII. Within the month I’ll also try to cover other interesting cases such as the German investigations on the solution of the Enigma by the Polish codebreakers and the FLD code used by French War Ministry in the period 1939-1940.

Cryptome has a kickstarter campaign. If you can support them, do so!
