This was a simple, hands-on encryption session for #ipdx19. We start the session with Morse code—SOS is recognizable to a handful of adults in each session. And then we transition to a Caesar Cipher, a pigpen cipher, and time to develop our own codes and keys with a partner.
My favorite segment of this workshop is the encryption primer (video below). Mia Gil Epner does a fantastic job of explaining encryption, especially asymmetric encryption and the challenges ahead as computer processing power increases.
