      return the iteration count.
      Returns:
      the iteration count.
    • generateDerivedParameters

      public abstract CipherParameters generateDerivedParameters(int keySize)
      generate derived parameters for a key of length keySize.
      Parameters:
      keySize - the length, in bits, of the key required.
      Returns:
