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.
