Cryptography is the invisible shield of the digital world, but its roots stretch back through millennia of human history. This workshop, indeed, offers a hands-on retrospective of this fascinating field. In four hours, we will journey from the simple yet effective Caesar cipher to the mind-bending principles of quantum cryptography. Participants will not only learn the historical and theoretical underpinnings of these cryptographic systems but will actively engage with them through a series of hands-on challenges. We will explore the cat-and-mouse game of code-makers and code-breakers, understanding how vulnerabilities in one generation of cryptography spurred the innovations of the next. The workshop is designed to be accessible to those with a foundational understanding of security concepts, providing a tangible and discursive look at how we've protected our secrets through the ages and what the future holds for this critical domain. Attendees will leave with a richer appreciation for the elegant mathematics and clever designs that secure our digital lives.
