Digital certificates help prevent third parties from intercepting messages and data sent across a network, impersonating computer servers, and hacking into private accounts by encrypting messages and data sent over the network.

Digital certificates can be displayed as a small window containing an image of the certificate owner.

It may also display the date and time when the certificate will expire and what name was used to create it.
