Public Key Infrastructure (PKI) is a system that supports secure digital communication using pairs of cryptographic keys—public and private. It guarantees confidentiality, integrity, authentication, and non-repudiation by managing digital certificates through trusted Certificate Authorities (CAs). PKI is essential for secure web connections (HTTPS), encrypted emails, digital signatures, and access control, leveraging asymmetric encryption where the public key is shared and the private key is kept secret.
