DESCRIPTION:Tens of thousands of encrypted messages from the last 500 years
  have survived in archives\, libraries\, collections\, and attics. This in
 cludes encrypted dispatches from aristocrats and diplomats\, encrypted mil
 itary messages\, encrypted telegrams\, encrypted newspaper advertisements\
 , encrypted postcards\, encrypted diaries\, and encrypted messages created
  by criminals. Previously unknown ciphertexts are discovered frequently.\n
 DECODE\, 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 di
 fficult. And then\, there are still numerous unsolved ciphertexts from the
  last 500 years. As a result of inter-disciplinary research\, techniques f
 or breaking historical ciphers have made considerable progress in recent y
 ears.\nThis presentation introduces the most important historical ciphers 
 and modern techniques to break them - based on the 2023 book “Codebreaki
 ng: A Practical Guide” authored by the presenters. Many real-world examp
 les are provided\, with slides that use an entertaining style including Le
 go brick models\, self-drawn cartoons\, and animations.
