About the Website

Dear visitor, I have a broad interest in all things technology, science and history, with a main focus on electronics, programming and cryptology. I also have a passion for old crypto equipment and signals intelligence, both technically and historically, and in WW2 and Cold War history. The combination of all this resulted in a desire to bring to life some of the marvels of cryptology through software simulations, with an emphasis on authenticity and respect for their history.

In 2004, I decided to share my passion for cryptology and cipher machines through 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 cryptology, intelligence, and how it influenced modern history. History is here to share!
