View certificate details—check authenticity
You can only be sure of the correct identity of a server
when the signature and the validity period 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. 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.
● Expired certificate — The certificate validity period
has ended.
● Certificate not valid yet — The certificate validity
period has not yet begun.
● Certificate corrupted — The certificate cannot be
used. Contact the certificate issuer.

the applications that can use the selected certificate is
shown. For example:
