About

My name is Klaus Schmeh.

For more than 30 years, I have been fascinated by the world of cryptography and encryption technology.

Professionally, I work for a company that develops encryption software for the Internet. In my spare time, I focus on the history of cryptography – from the legendary Enigma machine of World War II to the mysterious Voynich Manuscript, which remains undeciphered to this day, to name just a few examples.

Over the years, I have written numerous books, magazine articles, and scientific papers on my favorite subject. I have appeared on television and radio and have given many talks at conferences and other events.

This website offers a wide range of information about the history of cryptography, including:

Ciphers & Crime

And much more

In addition, this site features a blog dedicated to the history of cryptography.
