A digital certificate is a series of numbers that indicate the identity information of all communication parties in Internet communication, and provides a way to verify the identity of communication entities on the Internet. A digital certificate is not a digital ID card, but a stamp or seal (or a signature added to the digital ID card) stamped by an identity authentication institution.

It is issued by an authoritative organization: CA, also known as Certificate Authority Center, and people can use it to identify each other online.

Generally speaking, users should bring relevant certificates to certificate acceptance points in various places, or directly go to the certificate issuing agency, namely CA Center, to fill out the application form and conduct identity verification.
