Certificate management

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 phone.

Press to see a list of personal certificates, if available.

Options in the certificate management main view are Certificate details, Delete, Trust settings, Mark/Unmark, Help, and Exit.

Glossary: Digital certificates are used to verify the origin of the XHTML or WML pages and installed software. However, they can only be trusted if the origin of the certificate is known to be authentic.

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 phone are correct.

View certificate details—check authenticity

You can only be sure of the correct identity of a server when the signature and the period of validity of a server certificate have been checked.

You are notified on the phone display if the identity of the server is not authentic or if you do not have the correct security certificate in your phone.

To check certificate details, scroll to a certificate, and select Options > Certificate details. When you open 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. See ‘Change the trust settings’, p. 94.

•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.
