What is Public Key Infrastructure (PKI)?

A public key infrastructure (PKI) is a set of hardware, software, people, policies, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates and manage public-key encryption. It enables users of a unsecured network to securely exchange data and money through the use of a public and a private cryptographic key pair that is obtained through a trusted authority. The public key infrastructure provides for a digital certificate that can identify an individual or an organization and directory services that can store and, when necessary, revoke the certificates.
