9. Atbash

In this episode, we talk about Atbash, a simple substitution cipher, with Fred Fine & The Evil Ant. Atbash, for those who haven't heard, was first recorded in the book of Jeremiah, and in other Israelite writings. Plus, The Evil Ant has another plot, the security of Atbash is discussed, we learn more about the new recruit, and hear just how mathematical codes really are.
