actions that involve transferring confidential
information. They should also be used if you want to
reduce the risk of viruses or other malicious software and
be sure of the authenticity of software when
downloading and installing 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.

You can only be sure of the correct identity of a server
