This guy came in and talked to our class about different kinds of codes, some techniques dating way back to the times of Julius Caesar, and we got to practice writing messages with a partner in the different types of code. One basic type is where letters represent other letters, more complicated ones include a jumble up of the words (similar to an anagram) to make it even harder to decode.
He discussed how different countries' military used these types of codes in the past to help send messages to one another, and how they have gotten more and more complex over time.
Nowadays we have computers that can make up incredibly more complicated methods of coding things for all sorts of purposes, from online banking to storing of various sensitive information.
