Crypto This module allows you to configure SSl for use with most KDE applications, as well as manage your personal certificates and the known certificate authorities. KDE Wallet Here you can change your KDE Wallet Manager settings. KDE Wallet aims to provide secure storage for passwords and web form data. You can group different passwords in different wallets, and each one will only be opened with a master password (which you should never forget!). The default wallet is named "kdewallet", and you can either create a new wallet for your local passwords or accept the default wallet for all data in the "Automatic Wallet Selection" section. KDE programs like Konqueror, Kmail and Kopete are fully compatible with the KDE Wallet Manager. All of them will ask at least once for permission to access to actual wallet. You can give different access levels, such as "always allow", "allow once", etc. If you want to change that access level, you can do it from the "Access Control" tab by deleting the program entry and selecting a new preference the next time that application requests access to the wallet. Wallet Preferences To enable the KDE wallet subsystem, check the Enable the KDE wallet subsystem box. Unchecking this box will disable the KDE Wallet on your system. By default, KDE Wallet Manager is kept opened until the user session is closed, but you can change that in the Close Wallet section to close it when unused for a time, when a screen saver starts or when the last application stops using it. As you can have several wallets, Automatic Wallet Selection allows you start KDE with a given wallet. KDE Wallet will appear in your system tray by default, but you can hide it. Uncheck Show manager in the system tray to keep it always hidden, or check Hide system tray icon when last wallet closes to hide it only when all wallets are closed. These items are in the Wallet Manager section. Access Control You can set here what policy you want for your KDE applications, regarding to the wallet use. Password & User Account You can change here your personal information which will be used in mail programs and word processors.
