MORE INFORMATION

There are two types of security certificate issuers: root authority, and non-root authority. A non-root authority security certificate issuer is trusted by, and issues certificates on behalf of, a root authority. A root authority security certificate issuer is a certificate issuer that verifies the safety of the content on a Web site. For a browser program to use a security certificate, the program must "know" the issuing authority. In Internet Explorer versions 3.x, 4.0, and 4.01, a group of authorities are "known" by default. New authorities may be added according to the issuing software.
