How to Create a Grille Cipher – also by Hand :-)

#cryptology, #cryptography, #cryptanalysis In this video, we show how you can create your own turning grille ("Fleissner Schablone") using paper or cardboard, pen and pencil, scissors, and a ruler. Also, we give a short introduction of the history of the grille cipher. Finally, we will have a look at a modern implemention of a turning grille cipher, as well as the cryptanalysis of a grille cipher, in our sister project JavaCrypTool. If you are interested in learning the basics of cryptology, you should also have a look at our video series about basics of cryptology – also for beginners: https://youtu.be/jbumW7Ym03o You may download the latest version of JavaCrypTool from here: https://www.cryptool.org/en/jct-downloads You may download the latest version of CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Like what I do 😄?
