What is Public Key Infrastructure (PKI) Software?

Public Key Infrastructure (PKI) software provides a framework for secure communications, managing digital certificates and encryption keys for data protection and identity verification. It enables organizations to authenticate users, devices, and applications, ensuring that only authorized entities can access sensitive information. PKI software supports encryption, enabling secure data exchange over networks by encrypting data with a public key that only a corresponding private key can decrypt. It also facilitates digital signatures, providing non-repudiation and ensuring data integrity by verifying that the data has not been altered. Overall, PKI software is essential for establishing trust in digital communications, especially in environments requiring high-security standards, such as government and financial institutions.
