Certificate manager

Select Menu
Security

Digital certificates are used to verify the origins of
software but do not guarantee safety. There are three
>
different types of certificates: authority certificates,
personal certificates, and server 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 on 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.
Download a certificate from a web site, or receive a
certificate as an e-mail attachment, or as a message sent
>
through a Bluetooth or infrared connection. 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.
