A certificate authority system is the application which is responsible for creating digital certificates. Once the certificates have been created, the administrator of the system can send email messages to those people who need a CA. The email message often contains a link right to the CA log in, where they enter information to gain access. Once their information is verified, they are issued their digital certificates.
You Can Apply Directly to Your Certificate Authority to Get a Digital Certificate
Another way to obtain a digital certificate when you need one is to apply directly to your certificate authority. You will need to obtain the network location for the system from your administrator. Once you access the location, you just complete the online application and submit it. The person with the authority to approve requests will review your application and, if approved, you should be sent a follow-up email for completing the CA process to get your digital certificate.
