Security information

Security information is displayed when Certificate manager cannot be sure of the origin of the page or software. For example, security information will be displayed if:

The certificate on a page has expired.

The identity of a software manufacturer cannot be verified.

Security information is also displayed when a certificate on your

P908 has:

Expired.

Been revoked by the independent organisation that issued it.

Type of certificate

The type can be either User or Certificate Authority.

User certificates contain your identity. This type of certificate is used when the server asks for client authentication. The client application requests you to identify yourself by choosing a user certificate.

Certificate Authority certificates contain server details. This type of certificate is handled by your P908 when the server only requires server authentication. This means that your identity remains anonymous.

Adding and deleting certificates

Your P908 handles certificates automatically so, most of the time, you can browse the Internet securely without using Certificate manager. If you do need to add or delete a certificate, you will usually be informed by your network operator or system administrator. You should delete a certificate from Certificate manager if you are informed, or suspect, that:

The certificate does not belong to the person who supplied it.

The certificate was issued incorrectly by the independent organisation that created it.

Flip removed

This dialogue lets you enable the use of the Virtual flip when the flip of your P908 has been removed, see ‘Virtual flip’ on page 17.

Format disk

This dialogue primarily lets you rename and format any Memory Stick Duo that you install in your P908. Your P908 comes with one Memory Stick Duo.

When you format a disk, you delete all the information on it, including any applications that you may have installed. You also delete all information placed on it by other devices (these folders are hidden except in File Manager).
