remote server to transfer confidential information.

They should also be used if you want to reduce the risk

of viruses or other malicious software, and to check the

authenticity of software when you download and

install software to your device.

Tip: When you add a new certificate, check its

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.
To view certificate details, open a certificate folder, and

select a certificate and 

 > 

.

One of the following notes may appear:
•

  — You have not set any

application to use the certificate. You may want to

change the trust settings.

•

  — The period of validity has

ended for the selected certificate.

•

  — The period of validity

has not yet begun for the selected certificate.

•

  — The certificate cannot be

used. Contact the certificate issuer.

Trusting a certificate means that you authorise it to

verify web pages, e-mail servers, software packages,

and other data. Only trusted certificates can be used to

verify services and 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.
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.
To change the trust settings, select a certificate and

 > 

. Select an application field

and press the scroll key to select 

 or

change the trust settings of a personal certificate.

system application.
