Overview of Private Certificate Application

Private Certificate Authority (PCA) is a private CA and certificate management platform. It allows you to set up a complete CA hierarchy and use it to issue and manage private certificates within an organization through simple and visualized operations. It is used to authenticate application identities and encrypt and decrypt data within an organization.

Certificates issued by private CAs are trusted only within your organization but not trusted on the Internet. To use a certificate that is trusted on the Internet, purchase an SSL certificate. For details, see Purchasing an SSL Certificate.

For details, see Figure 1 and Table 1.
