Assignment:
For this assignment, you’ll be making a Brute Force Code Cracker. It will take a cipher for input and run through all possible shift-cipher keys for it. Keep in mind that there are only 26 possible keys for a shift cipher. After taking in a cipher input, you’ll need to, one-by-one, convert the characters that make up the string into numbers, shift them based on the key you’re currently testing, then shift them back to characters. Characters, when converting to numbers, always take their ASCII values. Lower-case ‘a’ is 97, while lower-case ‘z’ is 122. Upper-case ‘A’ is 65, while upper-case ‘Z’ is 90. All the letters between them have the numbers ranging between them. Also, keep in mind that you’ll need to use modulo to take into account letters that might shift past the end of the group, such as trying to shift ‘y’ five letters to the right.
The following cipher decodes as ‘Testing the System’ and may be used to verify your code.
