DESCRIPTION:Tens of thousands of encrypted messages from the last 500 year
 s have survived in archives\, libraries\, collections\, and attics. This i
 ncludes encrypted dispatches from aristocrats and diplomats\, encrypted mi
 litary messages\, encrypted telegrams\, encrypted newspaper advertisements
 \, encrypted postcards\, encrypted diaries\, and encrypted messages create
 d by criminals. Previously unknown ciphertexts are discovered frequently.\
 nDECODE\, a database for historical ciphertexts\, currently has about 8000
  entries\, and it keeps growing (https://de-crypt.org/decrypt-web).\nWhile
  many of these old cryptograms are easily broken today\, others are more d
 ifficult. And then\, there are still numerous unsolved ciphertexts from th
 e last 500 years. As a result of inter-disciplinary research\, techniques 
 for breaking historical ciphers have made considerable progress in recent 
 years.\nThis presentation introduces the most important historical ciphers
  and modern techniques to break them - based on the 2023 book “Codebreak
 ing: A Practical Guide” authored by the presenters. Many real-world exam
 ples are provided\, with slides that use an entertaining style including L
 ego brick models\, self-drawn cartoons\, and animations.
