PKI (Public Key Infrastructure)

Public Key Infrastructure (PKI) is a system that manages digital keys and certificates to secure online communications. It uses two types of keys: a public key, which anyone can access, and a private key, kept secret by the owner. PKI ensures that when you send encrypted messages or verify identities online, such as during banking transactions, you can trust that the data is secure and that the parties involved are who they claim to be. By establishing a framework for encryption and digital signatures, PKI enhances the security and integrity of digital interactions.
