/**
 * Interface for classes that reference a secret key stored on a smart card.
 * Different cards use different ways of identifying a key on the card,
 * for example file names, indexes, numbers, logical names.
 * Wherever a card service interface needs to identify a secret key on card,
 * the interface should use type <tt>SecretKeyRef</tt>.
 * Concrete card service implementations should then support a subset
 * of the subclasses of <tt>SecretKeyRef</tt>, for example
 *<tt>SecretKeyFile</tt> for cards that store their keys in ISO files.
