PKI is a set of components needed to issue and manage digital certificates. It includes hardware, software, policies and people. Certificates contain a subject's public key and are digitally signed by a certificate authority. PKIs can be public, where any system can validate certificates, or private, where only an organization's systems participate. Building a private PKI requires designing certificate templates and revocation processes. Managing certificates involves enrollment methods and checking certificate status.
