One-Time Pod explores the history of cryptography through episodes produced by students in Derek Bruff's first-year writing seminar at Vanderbilt University. 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. Thanks to Joe Hills for the title suggestion.
