Public Key Infrastructure (PKI)

What is Public Key Infrastructure (PKI)?
Public Key Infrastructure (PKI) is a system that uses digital certificates to verify and authenticate the identity of users, devices, and services. It relies on cryptographic keys – a public key for encrypting data and a corresponding private key for decrypting it. PKI establishes a trusted environment for secure electronic transactions and communication by managing digital certificates that bind a public key to an identity, ensuring that the communication is from a trusted party.
