Class TMMHParameterSpec

public class TMMHParameterSpec extends Object implements AlgorithmParameterSpec

This class represents the algorithm parameters for the Truncated Multi-Modular Hash function for use with JCE-derived instances of TMMH16.

This class is little more than a container for the key stream, tag length, and prefix parameters for the TMMH algorithm.
