CIPHER MACHINES AND CRYPTOLOGY
About This Website

About the Website

I have a broad interest in technology, science and history, but especially in cryptology, electronics and programming. I also have a keen interest in old cipher machines, classical cryptology and signals intelligence, both technically and historically, and in WW2 and Cold War history.

In 2004, I decided to share my passion for cryptology and cipher machines by creating this website and the SIGINT Chatter blog. My goal is to get people interested in the intriguing world of cryptography and codebreaking, and to show how a seemingly boring subject can be a truly fascinating journey into history. I hope to inspire the reader to look beyond the well-known WW2 and Cold War stories, to discover the importance of intelligence work and how it influenced modern history.
