What is PKI?

PKI stands for Public Key Infrastructure. It is a system that uses a combination of digital certificates and public key encryption to secure communications and authenticate identities.

A PKI system includes a certificate authority (CA) that issues digital certificates containing a public key and the certificate holder's identity. These certificates encrypt and decrypt messages and verify the sender's identity.

PKI is commonly used to secure online transactions, such as online banking and e-commerce, as well as secure email and virtual private networks (VPNs).

It also plays a vital role in securing IoT devices. PKI allows for trust in a digital environment by providing digital certificates and key pairs to establish trust and secure communications.
