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.

Certificate trust settings

Trusting a certificate means that you authorize it to verify
web pages, e-mail servers, software packages and other data.
Only trusted certificates can be used to verify services and
software.
Important: Even if the use of certificates makes the
risks involved in remote connections and software
installation considerably smaller, they must be used correctly
in order to benefit from increased security. The existence of
a certificate does not offer any protection by itself; the
certificate manager must contain correct, authentic, or
