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.
Certificate trust settings
Select Menu > Ctrl. panel > Settings and General > Security > Certificate
management.
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. Scroll
to 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.
Online certif. check — Online certificate status protocol.
View and edit security modules
