About
the Website
I have a broad interest in 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 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. History is here to share!
