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 authorize 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.
