NCDevCon Session Spotlight: A Brief Introduction to Cryptography

In this presentation we will look at the basics of cryptography. We will discuss how encryption and decryption work and some of the basic principles of cryptography. We will cover the basics of symmetric and asymmetric cryptography, cryptographic keys and key management, cryptographic modes of operation, and the uses of cryptography. We will briefly look at code samples in a few server-side languages to see how crypto is handled in each.
