Certificates
Important: Note that 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.
There are three kinds of certificates: server certificates, authority certificates, and
user certificates. You may receive these certificates from your service provider.
