Lists keys in the currently-selected vault.
Calling this method will fire the KeyList event once for each key, and will also populate the Key* properties. However, note that by default the following properties will not be populated, since the server does not return full information for keys when listing them. The IncludeKeyDetails property can be enabled to have the component attempt to retrieve full information for each key; refer to its documentation for more information.
If there are still more keys available to list when this method returns, the KeyMarker property will be populated. Continue to call this method until KeyMarker is empty to accumulate all pages of results in the Key* properties.
The MaxKeys configuration setting can be used to control the maximum number of results to return at once.
