Cipherbrain Blog (old)

For almost ten years, I ran the blog Cipherbrain, where I wrote about cryptography, codebreaking, historical ciphers, and unsolved encrypted messages. The blog became a widely recognized resource for cipher enthusiasts, researchers, and historians, featuring articles on both classical and modern cryptographic topics as well as reports on newly discovered and decoded ciphers.

Codebreaking-Guide

Codebreaking: A Practical Guide is a book I wrote with Elonka Dunin.

HistoCrypt videos

HistoCrypt is the leading European conference dedicated to the history of cryptology. I have attended every edition of HistoCrypt and have produced a video report from each conference. On this page, you will find all of these videos.
