Digital certificates do not guarantee safety; they are
used to verify the origin of software.
In the certificate management main view, you can see
a list of authority certificates that are stored in your
device. Scroll right to see a list of personal certificates,
if available.
Digital certificates should be used if you want to
connect to an online bank or another site or remote
server for actions that involve transferring confidential
information. They should also be used if you want to
reduce the risk of viruses or other malicious software
and be sure of the authenticity of software when
downloading and installing 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 trusted certificates for
increased security to be available. Certificates have a
restricted lifetime. If "Expired certificate" or
"Certificate not valid yet" is shown even if the
>
certificate should be valid, check that the current date
and time in your device are correct.
