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.

One of the following notes may appear:
•

  — You have not set any

application to use the certificate. You may want to change

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

 > 

. Scroll to an application field, and

press the scroll key to select

the trust settings of a personal certificate.

•

  — Online certificate status protocol.
