5.5. Explain core concepts of public key cryptography.

Public key cryptography is technically a subset of asymmetric cryptography. Furthermore, PKI (Public Key Infrastructure) is a framework for deploying asymmetric (or public key) cryptography, along with symmetric cryptography, hashing, and certificates, to obtain a real-world flexible and functional secure communications system. The following sections discuss various aspects of PKI and its sub-elements (rather than focusing only on public key cryptography).
