Consider the "Not-So-Simple-Substitution" cipher, where the shift size could be arbitrary. Write a program (using a programming language of your choice) that can cryptanalyze this cipher. Your program should take a ciphertext input in the form of a file, and find the key and output the plaintext(s) in the form of another file. This could be accomplished in a semi-automated manner (i.e., a human/cryptanalyst can guide your program by providing some suggestions at runtime). You can use any resource you need (programming libraries, English dictionary, etc.) to accomplish this task. Do not copy code from the Internet or anyone else. Demonstrate that your technique works for different ciphertext input files. Submit the following to Blackboard by the deadline as single zip file with the file name .zip. (a) A one to two page pdf report detailing the overall approach that was taken to solve this problem. Use figures to illustrate the approach. Explain the roles and efforts of each of the team members. Typeset using a word-processing software in a professional manner. (b) Just the source code. No executables and/or metadata files, please. One submission per team is sufficient. Points: 8 points for the work. 2 points for following the above instructions to the dot. Total 10 points.
