Project: Caesar Cipher

Author: Brian T.

Collaborators: Brendon H.

Feature Tasks and Requirements

1. Create an encrypt function that takes in a plain text phrase and a numeric shift.
   1. the phrase will then be shifted that many letters.
      1. E.g. encrypt(‘abc’,1) would return ‘bcd’. = E.g. encrypt(‘abc’, 10) would return ‘klm’.
   2. shifts that exceed 26 should wrap around.
      1. E.g. encrypt(‘abc’,27) would return ‘bcd’.
2. shifts that push a letter out or range should wrap around.
3. E.g. encrypt(‘zzz’,1) would return ‘aaa’.
4. Create a decrypt function that takes in encrypted text and numeric shift which will restore the encrypted text back to its original form when correct key is supplied.
5. create a crack function that will decode the cipher so that an encrypted message can be transformed into its original state WITHOUT access to the key.
6. Devise a method for the computer to determine if code was broken with minimal human guidance.
