One-Time Pod is a podcast that explores the history of cryptography through episodes produced by students in the 2017, 2018, and 2019 offerings of this first-year writing seminar. Each episode considers a different code or cipher, how it works, and why it’s interesting. The title is a play on the term “one-time pad,” a cipher that’s used just once and is thus perfectly secure.

You can listen to all the episodes below, listen on Spotify or Apple Podcasts, or add the RSS feed to your favorite podcast app. For teachers, you can find the podcast assignment and grading rubric here. Thanks to Gilbert Gonzales for the inspiration for this assignment.
