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.
@since JDK 1.2
