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.
