Certificate authorities

A certificate authority (CA) is used to sign other server and client certificates. Different CAs can be used for different domains or certificates. For example, if your organization is international you may have a CA for each country, or smaller organizations might have a different CA for each department. The benefits of multiple CAs include redundancy, in case there are problems with one of the well-known trusted authorities.

After you have created a CA certificate, you can export it to your local computer.
