I led a workshop where I introduced the audience (around 25 physics undergrads) to cryptography and some basic number theory/modular arithmetics.
As a group, we learned about monographic and digraphic substitution ciphers (the affine cipher and the hill cipher, respectively) and the intuition behind public key cryptography, among other things.
