The Unabomber's ShackMy podcast “Kaczynski Ciphers: The Unabomber’s Unused Encryptions” is about the serial killer Dr. Theodore Kaczynski. It covers what he did before starting a life of crime, the reason for his crimes, the consequences of his actions, and ultimately, what led him to be caught and his criminal career coming to an abrupt halt. The podcast also covers how the FBI initially reacted to the ciphers that they found and how they went about the situation. For a good portion of the podcast, I explain how the two codes Kaczynski created worked, and also provided an example of how someone could encode something using his methods.
