• Installing these packages on kali is as easy as running the following commands on terminal:

Code:
sudo apt-get update
sudo apt-get install qpdf unrar

• some python modules in this program need to be installed manually, like: zipfile, rarfile, crypt, pyfiglet, py-term(for term module) and so on. you can use pip3 for install them example:

Code:
pip3 install py-term

• notice: rar,zip and pdf files must have an extension, shadow files does not need an extension.

Features

• Cracking files password using two methods: 1. dictionary method 2. brute force method
• In the brute force method, you can specify the min length and max length of the passwords.
• In the brute force method, you can specify the type of characters that may be used in the password.
• There is a percent progress bar showing how much of the process has been performed.
• Error handling.
• One of the most important features of Zydra is the multiprocessing feature that speeds up the program. For example if you have 8 CPU cores, Zydra will use all of them for processing at the same time.

Examples
1- Dictionary search to find the password for a zip file
In this example I use rockyou.txt dictionary
Code:
python3 Zydra.py –f file.zip –d rockyou.txt

2- Brute force search to find the password for the users in the shadow file
Minimum length of password is 4 and maximum length is 4 and we try to find passwords that are composed of numbers and symbols letters.
