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.

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.
Before changing any certificate settings, you must
make sure that you really trust the owner of the
certificate and that the certificate really belongs to
the listed owner.
