/**
 * Key to P11Key translation cache. The PKCS#11 token can only perform
 * operations on keys stored on the token (permanently or temporarily). That
 * means that in order to allow the PKCS#11 provider to use keys from other
 * providers, we need to transparently convert them to P11Keys. The engines
 * do that using (Secret)KeyFactories, which in turn use this class as a
 * cache.
 *
 * There are two KeyCache instances per provider, one for secret keys and
 * one for public and private keys.
