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.
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.

Change the trust settings
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.
Scroll to an authority certificate, and select Options > Trust
settings. Depending on the certificate, a list of the
applications that can use the selected certificate is shown.
For example:
● Symbian installation: Yes — The certificate is able to
certify the origin of a new Symbian operating system
application.
● Internet: Yes — The certificate is able to certify servers.
● App. installation: Yes — The certificate is able to certify
the origin of a new Java application.
Select Options > Edit trust setting to change the value.
