Certificate management

Digital certificates do not guarantee
safety: they are used to verify the
origins of software.
To view a list of authority
certificates that have been stored in
your phone, select
Settings > Security
management. To see a list of
personal certificates if available,
scroll right.
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.
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.
Before changing any certificate
settings, you must make sure that
you really trust the owner of the
certificate and that the certificate
really belongs to the listed owner.
View certificate details and 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.
The phone notifies you if the identity
of the server is not authentic or if
you do not have the correct security
certificate in your phone.
To check certificate details, scroll to
a certificate, and select
Certificate details. While opening
the certificate details, the phone
checks the validity of the certificate,
and one of the following notes may
appear:
Expired certificate
period has ended for the selected
certificate.
