management.
Digital certificates are used to verify the origins of software but do not
guarantee safety. There are three different types of certificates: authority
certificates, personal certificates, and server 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 on 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.
Download a certificate from a web site, or receive a certificate as an e-mail
attachment, or as a message sent through a Bluetooth or infrared
connection. 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.

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
card.
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.
To change the trust settings, select a certificate and
settings. Select an application field and press the scroll key to select
No. You cannot change the trust settings of a personal certificate.
Depending on the certificate, a list of applications that can use the certificate
is displayed:
