Digital certificates do not guarantee safety; they are used
to verify the origin of 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

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.
