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
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.
