It is used to authenticate users, devices, and applications, as well as to protect data in transit. PKI is based on the concept of public and private keys, which are used to encrypt and decrypt data. The public key is used to encrypt data, while the private key is used to decrypt it. PKI is used in a variety of industries, including banking, healthcare, and government. PKI is an important part of IT security, as it provides a secure way to authenticate users and protect data. It is also used to secure digital signatures, which are used to verify the authenticity of documents.
