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. A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which 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 i… WebApr 15, 2024 · Asymmetric encryption, also known as public-key cryptography, differs from symmetric encryption in that it uses two different keys for the encryption and decryption process.
