About
the Webmaster
Dirk Rijmenants has a broad interest in all
things technology, science and history, with a main focus
on electronics, cryptology and programming. He also has 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, Dirk decided to share his
passion for cryptology and cipher machines through this
website and the SIGINT Chatter blog. HIs 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. He hopes to inspire the reader to
look beyond the well-known WW2 and Cold War stories, to
discover the importance of cryptology and intelligence,
and how they influenced modern history. History is here
to share!
