PKI
PKI (Public Key Infrastructure) is a system that helps organizations keep their digital information secure. Think of it like a digital ID card system that ensures people and computers are who they say they are. Companies use PKI to protect sensitive information, secure email communications, and ensure website connections are safe. It's similar to how a passport proves your identity in real life, but for the digital world. When you see the padlock symbol in your web browser or use secure email, PKI is often working behind the scenes.
