Public Key Certificate

A public key certificate is a digital document that verifies the identity of an individual or organization online. It contains their public key and important information like their name and digital signature from a trusted authority called a Certificate Authority (CA). Think of it as an electronic ID card that assures your browser or application that it's communicating with the genuine entity, not an impostor. This helps secure online transactions, emails, and data sharing by enabling encrypted and trusted communication over the internet.
