![]() Authenticate entities you’ve never met (users, clients, servers, and other devices).What PKI Helps You DoĪt its core, PKI enables you to do three important things (we’ll dive into the specifics of these more a little later): These publicly trusted entities must meet specific security standards to issue certificates. On the internet, this involves using digital certificates that are issued by third-party certificate authorities (CAs). (More on asymmetric encryption is just a moment.)Įncryption is the process of taking plaintext (i.e., readable) data and turning it into something indecipherable without the use of a secret key. It relies on the use of public key infrastructure, which uses asymmetric cryptography (i.e., public key cryptography) to protect sensitive data from unintended eyes. It’s the rules, technical processes, and technologies that make it possible to exchange data securely on the internet. Public key infrastructure is the foundation of internet security and digital trust. Public Key Infrastructure Explained: What Is PKI? A Look at the Basics Let’s dive right into what you need to know about PKI basics. Have you recently made a purchase or shared other sensitive personal information with a website? If so, public key infrastructure likely had a hand in facilitating security for your internet transactions. ![]() Set your watch - we’ll cover all the PKI basics you didn’t know you didn’t know in less time than it takes to make a good cup of coffee ![]()
