public class KBKDFIterationVariableParam
extends KBKDFDataParameter

A KBKDF Iteration Variable Parameter is a type of KBKDF Data Parameter that either references the counter variable or otherwise is a pointer to the output of the previous PRF invocation. Note that in when used with Counter Mode KBKDF, this parameter must be initialized with the two argument constructor. In other KBKDF modes, in particular, Feedback and Pipeline modes, this must be initialized with the no argument constructor. To add an optional counter to the PRF input stream under Feedback and Pipeline modes, use KBKDFOptionalCounterParam instead.
