Building a Brute-Force Zip File Cracking Tool

This is the product of roughly 30-40 hours of work. It is a small program written in Python which will carry out a brute-force attack on a password-protected zip file. As the program takes a brute-force approach to the problem, it can take a while for the password to be guessed - a password only 5 digits in length using exclusively upper case letters still has 26^5 = 11881376 possible combinations. As the number of characters in the password and the number of character sets increase, you can see why brute-force attacks take so long. You can view the source code for this and the other programs in my cracking suite at (forgive the messy code, this suite of tools is the first fully functional piece of software I’ve ever written) or, if you want, you can download the code for this program from my mediafire at USAGE: [-h] [-v] NOOFCHARACTERS CHARACTERSET ZIPFILE --------------------
