This abstract class defines the Service Provider Interface for ExemptionMechanism . Security providers may implement this interface, but applications never need to use it. Note that the default "SunJCE" provider does not provide an implementation.

 public abstract class  ExemptionMechanismSpi  {  // Public Constructors  public  ExemptionMechanismSpi  ( );  // Protected Instance Methods  protected abstract byte[ ]  engineGenExemptionBlob  ( ) throws ExemptionMechanismException;        protected abstract int  engineGenExemptionBlob  (byte[ ]  output  , int  outputOffset  )  throws ShortBufferException, ExemptionMechanismException;        protected abstract int  engineGetOutputSize  (int  inputLen  );        protected abstract void  engineInit  (java.security.Key  key  )  throws java.security.InvalidKeyException, ExemptionMechanismException;        protected abstract void  engineInit  (java.security.Key  key  ,          java.security.AlgorithmParameters  params  )          throws java.security.InvalidKeyException,          java.security.InvalidAlgorithmParameterException,            ExemptionMechanismException;        protected abstract void  engineInit  (java.security.Key  key  ,          java.security.spec.AlgorithmParameterSpec  params  )          throws java.security.InvalidKeyException,          java.security.InvalidAlgorithmParameterException,          ExemptionMechanismException;   }
