Pigpen Cipher Explained (and Broken) – The Most Famous Cipher of the Freemasons

#cryptology, #cryptography, #cryptanalysis In this video, I explain how you can create a pigpen cipher and how to encrypt and decrypt text with the pigpen cipher. First, I give a short introduction to the pigpen cipher. Then, I show how the cipher is constructed. After that, I present the keyspace size of the cipher in a short cryptanalysis part. Finally, we have a look at an original pigpen ciphertext presented on Klaus Schmeh's Blog. First, I create a transcription of it. Then, I cryptanalyze and decrypt it using CrypTool 2. The used pigpen font for the example encryption can be downloaded here: https://fontmeme.com/schriftarten/pigpen-cipher-schriftart/ The (German) blog article of Klaus Schmeh with the pictures of the pigpen postcard is here: https://scienceblogs.de/klausis-krypto-kolumne/drei-verschluesselte-postkarten-aus-england/ 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 CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Like what I do 😄?
