Breaking Historical Ciphers with Modern Algorithms | Virtual Talk

A Virtual talk by Elonka Dunin and Klaus Schmeh.
Many old encryption methods are still hard to break today. For instance, cryptanalyzing a short 19th century Playfair cipher is far from trivial, and it is especially difficult when the ciphertexts are short. On the other hand, techniques for breaking historical ciphers have recently made considerable progress with computer-based cryptanalysis methods being successfully applied to break original WWII Enigma messages, as well as the most famous unsolved codes, a 1970 ciphertext sent by the Zodiac Killer.
This presentation introduces the most important historical ciphers, and modern techniques to break them with many real-world examples and entertaining slides using Lego brick models, self-drawn cartoons, and animations.

Interesting presentation. I didn't know that Zodiac cipher had been cracked.

I'm the founder and current GM of the peng a leng a deng society, and our cyphers and symbols are chronicly difficult to roll

[@sanderbos4243]

Loved this!

A remix in x2 saying higher and higher, step 101 then 102 into 103 would be awesome 👌 I enjoyed all the decodes at times two speed hmm

The over-elaborate Hillclimb explanation should have come after the explanation of frequency analysis. First refer people to the Scrabble game to understand FA. FA is done in daily newspaper puzzles and people do them on trains without reference to any app. I gave up after that...
