The Webmaster
Dirk Rijmenants has a broad interest in all
things technology, science, and history, with a primary
focus on electronics, cryptology, and programming. He has
a passion for old crypto equipment and signals
intelligence, both technically and historically, and
World War II and Cold War history. The combination of
these interests inspired him to bring to life some
marvels of cryptology through software simulations, with
an emphasis on authenticity and respect for their
history.
In 2004, he decided to share his
passion for cryptology and cipher machines through this
website and the SIGINT Chatter blog
. His aim is to
spark interest in the intriguing world of cryptography
and codebreaking, showing how a seemingly boring subject
can be a truly fascinating journey through history. He
hopes to inspire the reader to look beyond the well-known
World War II and Cold War stories, to discover the
importance of cryptology and intelligence, and how they
influenced modern history. History is here to share!
The number of visitors and kind
feedback encourages him to update and expand the site
whenever time allows. More info at the updates archive. He appreciates all feedback, additional
information or reporting of broken links, to improve this
site. You can send
an e-mail or provide feedback
in the guestbook.
