A key protector encapsulates functionality to retrieve an unlocking key for a fully-encrypted disk from a specific source. A key protector module registers itself with the key protectors framework when it is loaded and unregisters when unloaded. Additionally, a key protector may accept parameters that describe how it should operate. The key protectors framework, besides offering registration and unregistration functions, also offers a one-stop routine for finding and invoking a key protector by name. If a key protector with the specified name exists and if an unlocking key is successfully retrieved by it, the function returns to the caller the retrieved key and its length.
