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.
