Certif. management

Options in Certif. management are Certificate details, Delete, Trust settings, Mark/

Unmark, Help, and Exit.

In the certificate management main view, you can see a list of authority certificates

that have been stored in your phone. Scroll right to see a list of personal certificates,

if available.

Authority certificates are used by some browser services, such as banking services,

for checking signatures or server certificates or other authority certificates.

Server certificates are used to improve security in the connection between the

phone and the gateway. The phone receives the server certificate from the service

provider before the connection is established, and its validity is checked using the

authority certificates saved in the phone. Server certificates are not saved.

Server certificates may be needed, for example, when you want to do the following:

• Connect to an online bank or another site or remote server for actions that

involve transferring confidential information.

• Decrease the risk of viruses or other malicious software and be sure of the

authenticity of software when downloading and installing software.

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 phone are correct.

CHANGE THE TRUST SETTINGS OF AN AUTHORITY CERTIFICATE

Scroll to an authority certificate, and select Options > Trust settings. Depending

on the certificate, a list of the applications that can use the selected certificate is

shown. For example:

• Internet—The certificate is able to certify e-mail and imaging servers.

• App. installtion—The certificate is able to certify the origin of new software.

Before changing these settings, you must make sure that you really trust the owner

of the certificate and that the certificate really belongs to the listed owner.
