Certificate Manager
Digital certificates ensure that the web or WAP pages you visit, or
any software you install, really are created by the person you
expect.
Certificates may be presented on the pages that you view or the
software that you download. Your device compares these
certificates with a set of certificates that's stored in Certificate
manager to ensure the authenticity of the page or software. If the
certificates don't match, your device informs you, and allows you
to:
• Prevent the page being loaded or the software being
installed, or
• Continue at your own risk
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. 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.
Security Information
Security information is displayed when Certificate manager can't
be sure of the origin of the page or software. For example,
security information will be displayed if:
• The certificate on a page has expired
• The identity of a software manufacturer can't be verified
Security information is also displayed when a certificate on your
device:
• Has expired
• Has been revoked by the independent organization that
issued it
