A digital certificate is a digital file formed after a certificate authority (CA) authenticates the certificate requester, using the CA's root certificate to sign some basic information of the applicant and the applicant's public key, which is equivalent to the official seal of the issuing certificate authority. When the CA finishes issuing the certificate, it publishes the certificate in the CA's certificate library (directory server), which can be queried and downloaded by anyone, so the digital certificate is as public as the public key. In fact, a digital certificate is a CA-certified public key.
