Module 6: Cryptography

What You’ll Learn

In this module, we introduce you to the fun world of Cryptography and different methods of crypto. We will also go over RSA vs Diffie-Helman vs PGP ending on PKI infrastructure.


This module will cover the fundamentals of cryptography along with practical use cases in today’s world. It is an important aspect of security and forms the basis to many protocols that keep us safe. This module will help you understand what happens behind the scenes with these algorithms and how they are useful.
