You may use any tools you like, discussed in class or the textbook or on the internet, but you must cite and document every step of the way.

You must turn in a report by Tuesday October 14th detailing the cipher used for each question, the content of each question and how you derived that content, along with any ancillary code that you write.

Partial credit will be awarded for this exam. You may ask for a total of three hints. Each hint will be a deduction of 7 points from your exam score.
