/**

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.
