![]() Therefore with this article I aim to make transitioning to Python documentation easier for anyone who finds it too complex at their current level of coding (it’s my first blog article anyway). Now that I am more proficient in coding I think it’s very well written. I have been coding for almost four years now and at the beginning reading Python’s documentation was very overwhelming (at least for me). ![]() I want each article to be easily readable and not overwhelming for the reader.Īnd finally I want to explain (since you may already be asking, there is already a documentation for it why do we need an article) why I decided to write this post. There are two reasons I decided to write a three part series: - itertools module has three types of iterators, therefore each article will cover one of them. We will get to it and many more in this three part post series. The module contains many useful functions which you may already tried to implement at some point in your code for example, this function called product is equivalent of a nested for loop. Itertools is a great module which contains set of memory optimized iterator building blocks (you can read more about it in the Python itertools documentation). The good news is Python already has it in its standard library, in the module named as itertools. The most straight-forward way to do it is obviously with a for or while loop however, when the iterables get larger we need more efficient ways. Iteration is one of the key concepts in programming. The second code will not run on Windows, but can be modified to (have to remove the crypt module and references to it) For the assignment your deliverables are: source code for the dictionary attack, source code for the brute force attack, and the contents of the files.Wandering in the Python itertools Module - Part I Hint: Use the source code here (.) and here () for examples of how to brute force (exhaustively try passwords) and to use a dictionary file for password breaking. ![]() Make sure to unzip this file prior to working with it. You may Download Dictionary.zip which contains a word list - one word per line. The dictionary attack will require a wordlist. The password for Flag.zip has 8 characters. To accomplish this assignment you to write a bruteforce tool, you will need to use itertools to iterate through all possible characters. You can test your code against the, since you already know the password. ![]() which is has a password that is easier to brute force that the 8 character, number/letter combo on the Flag.zip file. You will have three zip Files - with password 'password', Flag.zip with a different password', and. Respond with the contents of that file and your source code. If your code works as it should, it should drop a Flag.txt file into the source code folder. After this assignment is turned in, the solution will be available on GitHub here Given this code to extract the password encoded zip file: from zipfile import ZipFile password = "password" encoding = "utf-8" zf = "" try: with ZipFile(zf) as z: z.extractall (pwd=bytes (password, encoding)) with open("") as p: data = p.readlines) print(data) except RuntimeError as e: print(e.message) Your assignment is to write a password cracker that can use brute force and dictionary attacks to open the file. Another update - 22 September 2021 - you may have to clean up the input where you read in the dictionary file - remember how to use string functions - like rstripe and Istripe. ![]() Update: 22 September 2021 - updated to use a shorter (hint - less than 5 character) password - to allow you test more quickly. ![]()
