cryptography

1) Using any programming language of your choice implement the Frequency analysis attack to break a vigenere cipher that is using a key of length 2. 2) Specifications: The program should take one input file which contains the text to decrypt. Assuming that the Vigenere cipher is repeating a key of length 2, write the code to break the cipher and output the two letter key and the plaintext to stdout. The code should be runnable through command line in the following way (assume the program is named as freqvis) 3) freqvig [login to view URL] key=xy output_textSubmission 4) Submit your code, the output for the following input (named [login to view URL]) in separate files via Blackboard by the due date. No zipped files allowed.
