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
