-/**
- * This class defines the <i>Service Provider Interface</i> (<b>SPI</b>)
- * for the <code>SecretKeyFactory</code> class.
- * All the abstract methods in this class must be implemented by each 
- * cryptographic service provider who wishes to supply the implementation
- * of a secret-key factory for a particular algorithm.
- * <p>
- * A provider should document all the key specifications supported by its
- * secret key factory.
- * For example, the DES secret-key factory supplied by the "SunJCE" provider
- * supports <code>DESKeySpec</code> as a transparent representation of DES
- * keys, and that provider's secret-key factory for Triple DES keys supports
- * <code>DESedeKeySpec</code> as a transparent representation of Triple DES
- * keys.
