Digital certificates are used to verify the origins of software but do not guarantee safety.
There are four different types of certificates: authority certificates, personal certificates,
trusted site certificates, and device certificates. During a secure connection, a server
may send a server certificate to your device. Upon receipt, it is checked through an
authority certificate stored in your device. You receive notification if the identity of the
server is not authentic or if you do not have the correct certificate in your device.
You can download a certificate from a web site, or receive a certificate as a message.
Certificates should be used when you connect to an online bank or a remote server to
transfer confidential information. They should also be used if you want to reduce the
risk of viruses or other malicious software, and to check the authenticity of software
when you download and install software to your device.
Tip: When you add a new certificate, check its authenticity.

Trusting a certificate means that you authorise it to verify web pages, e-mail servers,
software packages, and other data. Only trusted certificates can be used to verify
services and software.
