	A modular implementation approach was taken in which, once the base functionality of the CipherGUI was coded, each cipher could be easily integrated by setting the encryption and decryption algorithms and building the unique central panel as described above. Figure 7, below, shows a screenshot of the working application. A large selection of ciphers is available via the dropdown list above the unique central panel, with areas designated for plaintext, ciphertext and frequency plots.		A modular implementation approach was taken in which, once the base functionality of the CipherGUI was coded, each cipher could be easily integrated by setting the encryption and decryption algorithms and building the unique central panel as described above. Figure 9, below, shows a screenshot of the working application. A large selection of ciphers is available via the dropdown list above the unique central panel, with areas designated for plaintext, ciphertext and frequency plots.

	The screenshot shows the Playfair Cipher in use. The user of the program has specified the input key “Music” and the cipher-square in the central panel has updated to reflect this choice of keyword. Letter frequencies of the ciphertext and plaintext are displayed in the graphs.		The screenshot shows the Playfair Cipher in use.

	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 6.

	Finally, a high level of communication played a key role in organising and collaborating project work. Communication was both in person and through the University email system including the Gmail chat functionality. Without this high level of communication, it is unlikely the project would have been as successful as it was, nor achieved nearly as much as it did.

Role Allocation

	The review and research of previous work was split equally since each project member needed to have a good understanding of the entire project and its status. The workload in the Cipher Analysis section (including the CipherGUI) was also equally shared. This was due to the compartmentalised nature of the cipher investigation; individual ciphers were all separate investigations so there was no major advantage in specialising.

	Searches for the initial letter sequences were more useful with fewer hits. Crawling approximately 50,000 websites returned only one significant result, a poem titled “My Love Is A Butterfly” by Katerina Yanchuk<ref name=Yan>Yanchuk, Katerina, ''My Love is a Butterfly'', http://www.poemhunter.com/best-poems/katerina-yanchuk/my-love-is-a-butterfly/</ref>, for the initialism “MLIAB”. The poem can be viewed [[My Love is a Butterfly\|here]]. Analysis has revealed no other links to the Somerton code in this poem and as such the match is considered a coincidence. A screenshot of the successful match is provided in the following thumbnail.		Searches for the initial letter sequences were more useful with fewer hits.

	The design of the GUI for the system was primarily done by Steven using the [http://netbeans.org/ Netbeans] IDE GUI development toolkit. The requirements of the user interface included allowing the user to specify: the seed website(s), the pattern and pattern type being searched for, and a result logging location.

	Testing also revealed some additional useful functionality provided by the crawler4j interface. This included parameters to limit: link depth explored, number of pages searched and domain. These features proved especially useful in the testing phase of the following [[Final Report 2011#System Integration\|System Integration]] section and have also been incorporated into the product for use by the customer.

	The design starts with a seed from which it attempts to load the protocol definition file robots.txt. If robots.txt does not exist or does exist but doesn’t limit crawling web page content is loaded from which embedded links are extracted. These links are added to the link queue via a sub-process as the thread returns to attempting to load the next web page in the queue.
