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
