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 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.
