Private PKI
Private PKI (Public Key Infrastructure) is a system for managing digital certificates and encryption keys within a private, controlled environment, such as an organization or enterprise. It enables secure authentication, encryption, and digital signing for internal systems, devices, and applications without relying on public certificate authorities. This infrastructure typically includes components like certificate authorities, registration authorities, and certificate repositories to issue and validate certificates.
Developers should learn and use Private PKI when building or maintaining secure internal systems, such as corporate networks, IoT devices, or microservices architectures, where trust must be managed internally. It is essential for scenarios requiring custom certificate policies, high security control, or compliance with regulations like HIPAA or GDPR, as it avoids dependence on external CAs and reduces costs for large-scale deployments.
