Certificate trust settings

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 Options > Trust settings. Select an application field and press the scroll key to select Yes or No. You cannot change the trust settings of a personal certificate. Depending on the certificate, a list of applications that can use the certificate is displayed:

•Symbian installation — New Symbian operating system application.

•Internet — E-mail and graphics.

•App. installation — New Java™ application.
