PKI

Public Key Infrastructure (PKI) is a system that securely manages digital certificates and encryption keys, enabling trusted online communication. It uses pairs of keys: a public key, which anyone can access, and a private key, kept secret by the owner. These keys work together to verify identities and encrypt data, ensuring that information exchanged between parties remains private and authentic. PKI underpins secure activities like online banking, email, and e-commerce, providing confidence that digital interactions are trustworthy and protected from eavesdropping or tampering.
