Certificate trust settings
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.
