-/**
- * KeyFactorySpi is the Service Provider Interface (SPI) for the 
- * KeyFactory class. This is the interface for providers to 
- * supply to implement a key factory for an algorithm.
- *
- * Key factories are used to convert keys (opaque cryptographic 
- * keys of type Key) into key specifications (transparent 
- * representations of the underlying key material).
- *
- * Key factories are bi-directional. They allow a key class 
- * to be converted into a key specification (key material) and
- * back again.
- *
- * For example DSA public keys can be specified as 
- * DSAPublicKeySpec or X509EncodedKeySpec. The key factory
- * translate these key specifications.
