The compelling attraction of the Internet is that it has made
gigabytes of information ubiquitous to people of all walks
of life. The impact of this pervasive information is that the protection
of sensitive data is a stronger mandate than ever before.
The mechanisms to
defend information are available but are all too frequently
ignored, possibly because of the inconvenience of
their application.
In this paper, we present the design and implementation
of a software component for encrypting data that is easily
incorporated into existing software applications.
We use the adapter or wrapper pattern to present
a meaningful interface to clients of the component.
We use the Unified Modeling Language, UML, to describe
our class design.
