Buy the encryption module if it isn't already included in the base cost. In network jargon, they are called crackers . Most of us haven't seen their work directly, but we've heard about them. Crackers are people who break into computers in order to read, copy, or delete data files and perhaps use one computer as a jumping off point to break into other computers. They also break into telecommunications systems.
Crackers are unlike hackers.
Hackers are characterized as having an intense curiosity about how computers work and sometimes create software to work around the limitations of operating systems. This curiosity and sense of independence have both good and bad sides. As an example of a good end, hackers have generally made it possible to do things with a computer that the original operating system designers never considered. On the other hand, cracking seems to have only negative consequences. The crackers report on their activities and their ability to break into the systems.
