Digital certificates should be used if you want to connect
to an online bank or another site or remote server for
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.
View certificate details—check authenticity
You can only be sure of the correct identity of a server
when the signature and the period of validity of a server
certificate have been checked.

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.
