Certif. management
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.
Press 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.
View certificate details—check authenticity
You can only be sure of the correct identity of a server
when the signature and the period of validity of a server
certificate have been checked.
You are notified if the identity of the server is not
authentic or if you do not have the correct security
certificate in your device.
To check certificate details, scroll to a certificate, and
select Options > Certificate details. When you open
certificate details, the validity of the certificate is checked,
and one of the following notes may be displayed:
• Certificate not trusted — You have not set any
application to use the certificate. See "Change the trust
settings", on page 105.
• Expired certificate — The period of validity has ended
for the selected certificate.
• Certificate not valid yet — The period of validity has
not yet begun for the selected certificate.
• Certificate corrupted — The certificate cannot be
used. Contact the certificate issuer.
