Important:Although 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.

VIEWING CERTIFICATE DETAILS—CHECKING AUTHENTICITY
You can only be sure of the correct identity of a browser gateway or a 
server when the signature and the period of validity of a browser gateway 
or server certificate have been checked. 

You will be notified on the phone’s display: 

•

If the identity of the browser server or gateway is not authentic. 

•

If you do not have the correct security certificate in your phone. 

To check certificate details, scroll to a certificate and select 

→

 

. When you open certificate details, Certificate 

management checks the validity of the certificate and one of the 
following notes may appear:

•

Certificate not trusted

—You have not set any application to use the 

certificate. For more information, see “Change the trust settings of an 
authority certificate” on p. 50.

•

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.

Important:Certificates have a restricted lifetime. If 

 or 

 is shown even if the 

certificate should be valid, check that the current date and time in 
your phone are correct.
