Help, and Exit.
In the Certificate management main view, you can see a list of authority certificates that
have been stored in your phone. Press to see a list of personal certificates, if available.
Authority certificates are used by some browser services, such as banking services, for
checking signatures or server certificates or other authority certificates.
Server certificates are used to improve security in the connection between the phone and
the gateway. The phone receives the server certificate from the service provider before the
connection is established and its validity is checked using the authority certificates saved
in the phone. Server certificates are not saved.
Server certificates may be needed when you, for example:
• want to connect to an online bank or another site or remote server for actions that
involve transferring confidential information, or
• want to decrease the risk of viruses or other malicious software and be sure of the
authenticity of software when downloading and installing software.
Important: Note that 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.
