===Design===
The key design feature to meet these technical challenges was the use of a modular design approach. This allowed multiple ciphers to be easily integrated into the central tool through just five lines of code. The issue of providing interactive functionality to ciphers with inherently different interfaces was solved through the allocation of a unique central panel set by each individual cipher, enabling descriptions, instructions, different key entry types and graphical aids. Real-time letter frequency graphs were also included to provide an analysis tool as well as dynamic tables and cipher alphabets. Zoom features on larger graphical aids were also designed.

Other design decisions included restricting language used to Java as this was the language project members had experience in and the use of the freeware [http://www.eclipse.org/downloads/ Eclipse IDE] minimising budget impact.

Another advantage of the modular structure of the CipherGUI software is that additional cipher methodology can be easily integrated in the future providing there is conformity to the established connection interface used by all exisitng individual cipher implementations. A conceptual software map is shown in Figure 8.
