Public Key Infrastructure

Public Key Infrastructure (PKI) is a system that manages digital keys and certificates to secure online communications. It uses pairs of keys: a public key, which anyone can access to encrypt messages, and a private key, kept secret by the owner to decrypt those messages. PKI helps verify identities, ensuring that parties in online transactions are who they say they are. This technology underpins activities like secure emails, online banking, and website security (HTTPS), fostering trust and confidentiality in digital interactions.
