• Authority certificates Authority certificates are used by some online services, such as banking services, for checking the validity of other certificates. Authority certificates can be saved in the security module by the service provider, or they can be downloaded from the network, if the service supports the use of authority certificates. • User certificates User certificates are issued to users by a Certifying Authority. User certificates are needed, for example, to create a digital signature, and they associate the user with a specific private key in a security module. Important: Note, however, 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 phone are correct. Before changing these settings, you must make sure that you really trust the owner of the certificate and that the certificate really belongs to the listed owner. Copyright © 2003 Nokia.

Authority certificates
Authority certificates are used by some online services, such as banking
services, for checking the validity of other certificates. Authority certificates
can be saved in the security module by the service provider, or they can be
downloaded from the network, if the service supports the use of authority
certificates.

User certificates
User certificates are issued to users by a Certifying Authority. User certificates
are needed, for example, to create a digital signature, and they associate the
user with a specific private key in a security module.
Important:
Note, however, 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 phone are correct.
Before changing these settings, you must make sure that you really trust
the owner of the certificate and that the certificate really belongs to the
listed owner.
