I find Cryptography and code breaking to be very interesting as there are huge implications on Cyber security. The current world is based on the presumption that cryptographic algorithms are secure, it is what ensures that we can use the internet, bank online, find love online and even work online. Cryptography historically has been a field working under heavy classification and there are multiple folks we don’t know about because their existence and work was classified.
Lambros Callimahos was one such Cryptologist, he was good enough that two of his books on Military Cryptanalytics covering code breaking (published in 1977) were blocked from public release till 1992. The third and last volume in the series was blocked from release till December 2020. It is now finally available for download as a PDF file so you can check it out.
The book covers how code breaking can be used to solve “impossible puzzles” and one of the key parts of the book is it’s explanation of how to use cryptodiagnosis to decrypt data that has been encrypted using an unknown algorithm. It has a whole bunch of examples and walks you through the process which is quite fascinating. I am going to try getting through it over the next few weeks if I can.
Check it out if you like to learn more about cryptography.
