Digital certificates are used to verify the origin of browser pages and 
installed software. However, they can only be trusted if the origin of the 
certificate is known to be authentic. 

Digital certificates are needed if you want to:

•

Connect to an online bank, another site, or remote server for actions 
that involve transferring confidential information.

•

Minimize the risk of viruses or other malicious software and be sure 
of the authenticity of software when downloading and installing 
software.

Authority certificates are used by some services, such as banking services, 
for checking signatures or server certificates or other authority 
certificates. User certificates are issued to users by a Certifying Authority.
