Digital certificates are used to verify the origins of
software but do not guarantee safety. There are four
different types of certificates: authority certificates,
personal certificates, trusted site certificates, and
device certificates. During a secure connection, a server
may send a server certificate to your device. Upon
receipt, it is checked through an authority certificate
stored in your device. You receive notification if the
identity of the server is not authentic or if you do not
have the correct certificate in your device.
You can download a certificate from a web site, or
receive a certificate as a message. Certificates should
be used when you connect to an online bank or a
remote server to transfer confidential information.
They should also be used if you want to reduce the risk
of viruses or other malicious software, and to check the
authenticity of software when you download and
install software to your device.
Tip: When you add a new certificate, check its
authenticity.

You can only be sure of the correct identity of a server
when the signature and the validity period of a server
certificate have been checked.

Certificate trust settings
Trusting a certificate means that you authorise it to
verify web pages, e-mail servers, software packages,
and other data. Only trusted certificates can be used to
verify services and 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.
