-/**
- * 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.
