==Public key cryptography is a cryptographic technique that enables entities to securely communicate on an insecure public network, and reliably verify the identity of an entity via digital signatures.[3]
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificateswhich are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository and revokes them if XSS vulnerability
