Lists the keys in the currently-selected key ring.
This method lists the keys in the currently-selected KeyRing.
Calling this method will fire the KeyList event once for each key, and will also populate the Key* properties.
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.
