The Webinar on A Walk Through Cryptography took place on Wednesday, July 14th, 2021 from 12 pm until 1:30 pm, with Pura Fornals, President of the Museum of Mathematics of Cataluña (MMACA), as our invited speaker. This virtual event was free and open to the general public.
The invited speaker explained that cryptography is an area of mathematics that deals with encrypting (hiding) and decrypting messages. Pura Fornals showed several examples of how to hide the message inside a text, twist the message, invent alphabets and disorder the message with a key word. The speaker also described the Spartan scytale, the Caesar cipher, the rotating circles, the substitution encryption, the symbol cipher and the enigma machine. This virtual event was co-organized with the Museum of Mathematics of Cataluña (MMACA).
