implementing triple des in java

Hi, all

i have downloaded a sample code for implementing triple des and i am trying to run that code in kawa software. it uses following additional classes

import cryptix.util.core.BI;

import cryptix.util.core.ArrayUtil;

import cryptix.util.core.Hex;

import cryptix.provider.key.*;

i have downloaded the above classes and it also appears under packages but then why does it give errors that "package cryptix.provider.key does not exist"
