[0002] Public Key Infrastructure (PKI) is the foundation and core of current network security construction and the basic guarantee for the implementation of e-commerce security. All concepts and technologies related to digital certificates are collectively referred to as PKI. PKI uses certificates to manage public keys. Through a third-party trusted institution (certification authority, or CA), it bundles the user's public key with other identification information of the user, including user name and email address, to verify the user's identity on the Internet. PKI combines public key cryptography with symmetric cryptography to achieve automatic key management on the Internet and ensure the secure transmission of online data.

[0003] A digital certificate is a file that is digitally signed by a certificate authority and contains information about the public key owner and the public key.
