Specifications

Develop a python program (please show a picture of your code) that implements the two password cracking methods and allows the user to crack .zip (archive) files.

The first task is to implement a driver loop that prompts the user for which file cracking method theyd like to use (brute force, dictionary, or both). After determining which method the user would like to use, call the respective function(s) and show the time each function took to run. The user should be able to quit by typing q. If the attack is both, do a dictionary attack first and do a brute force attack only if the dictionary attack failed.

The second task is to develop a brute force function that generates a strings containing a-z (all lowercase) of length 8 or less as the password to attempt (Hint: start small trying small passwords first). For example ,your string should start out with a, then b, then c, so on and so forth. When you get to z change the first character back to a and append another letter so your string becomes aa then ab. Once the password is cracked you should display the password to the user. Hint: see notes below about itertools.

The third task is to then develop the dictionary function. After you have prompted for the name of the dictionary file and the target .zip file your function should go through every line (one password per line) and try opening the .zip file. If it opens successfully, then again, display the password to the user. If you try all the passwords in the source file, display an appropriate error message. Hint: remember to strip() the word read from the file before trying it as a password!

The fourth and final task for this project is a research question. With this project we are providing you with two password protected .zip files. On behalf of the Computer Science Department you have our full permission to attack these two specific files for demonstration and educational purposes only. Breaking into secure computer systems is illegal in the US. (most other countries have similar laws). Your research question is to find out what US federal law youre breaking if you decide to do this without permission. Your program should warn the user what the name of the law is, and what the maximum penalty is before prompting for input. Assignment Notes You are also not allowed to use sets, lists, tuples, or dictionaries

Test Case 5

(In Test Case 5 use the short dictionary and the brute_force.zip file so the dictionary attack fails and doesnt take forever to do soforcing the brute force attack to be needed.)
