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.
To view certificate details, open a certificate folder, and

select a certificate and

ended for the selected certificate.

•

  — The period of validity

has not yet begun for the selected certificate.
