Method Detail

wrap

public KeysetDeriver wrap(KeysetHandleInterface keysetHandle,
                          MonitoringAnnotations annotations,
                          PrimitiveWrapper.PrimitiveFactory<KeyDeriver> factory)
                   throws GeneralSecurityException

Description copied from interface: PrimitiveWrapper

Wraps a PrimitiveSet and returns a single instance.

This method gets called when a new primitive is created.

Specified by:

wrap in interface PrimitiveWrapper<KeyDeriver,KeysetDeriver>

Throws:

GeneralSecurityException

getPrimitiveClass

public Class<KeysetDeriver> getPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive managed. Used for internal management. Should be implemented as return P.class; when implementing a wrapper creating objects of type P.

Specified by:

getPrimitiveClass in interface PrimitiveWrapper<KeyDeriver,KeysetDeriver>

getInputPrimitiveClass

public Class<KeyDeriver> getInputPrimitiveClass()

Description copied from interface: PrimitiveWrapper

Returns the primitive class object of the primitive used to create B. Used for internal management. Should be implemented as return B.class;.

Specified by:

getInputPrimitiveClass in interface PrimitiveWrapper<KeyDeriver,KeysetDeriver>

register

public static void register()
                     throws GeneralSecurityException

Registers this wrapper with Tink, allowing to use the primitive.

Throws:

GeneralSecurityException
