Remarks

A digital certificate is a common credential that provides authentication. A trusted organization, called a Certificate Authority (CA), assigns a certificate to a user or entity who then uses the certificate to prove itself to the other side. The user or entity is able to do this using a digital certificate because the certificate contains information necessary for the client to authenticate the server, including the following information:

The Certificate Authority's name.
The entity to whom the certificate was issued.
The entity's public key.
The dates the certificate is valid.
