Public Key Infrastructure

Public Key Infrastructure

Public Key Infrastructure (PKI) is a set of hardware, software, policies, and procedures used to manage the creation, distribution, and revocation of digital certificates. It provides a framework for secure communications and authentication in the digital world. PKI relies on asymmetric encryption, where each entity (such as an individual or an organization) has a pair of cryptographic keys: a public key and a private key.

Overall, PKI plays a crucial role in establishing trust and security in various digital applications and is widely used in sectors such as e-commerce, online banking, secure email communication, and more.
