+/**
+   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.
