# Zydra

Zydra is a file password recovery tool and Linux shadow file cracker. 

It uses the dictionary search or Brute force method for cracking passwords.

## Supported Files

*	RAR Files

*	Legacy ZIP Files

*	PDF Files

*	Linux Shadow Files (zydra can find all the user’s password in the linux shadow file one after the other)

## Prerequisites

To run the app, minimal requirements are:

*	Python 3.3 or higher

*	debian-based linux distro, preferably Kali linux 2

*	**qpdf** and **unrar** packages
 Installing these packages on kali is as easy as running the following commands on terminal:


```$ 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: 
```$ pip3 install py-term```


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

*   Install figlet font "epic" if it does not exists on your system:


 ```sudo wget http://www.figlet.org/fonts/epic.flf -O /usr/share/figlet/epic.flf```

## Disclaimer

This tool is only for testing and academic purposes Do not use it for illegal purposes!

## 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



```$ 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.



```$ python3 Zydra.py –f shadow –b digits,symbols –m 4 –x 4```

## Vagrant

To run Zydra using vagrant use the following command (you have to be in the same folder as the repository):



`vagrant up`



and once it finishes inialisation, you can run:



`vagrant ssh`



to connect to the virtual machine.



To exit the virtual machine just type `exit` in the shell.



To destroy the virtual machine run `vagrant destroy`.



More information regarding vagrant usage can be found [here](https://www.vagrantup.com/docs/cli/)



**Note:**

By default the `Vagrantfile` uses the following settings:

```

    vb.cpus = 4

    vb.memory = 4096

```

Edit the `Vagrantfile` and change those values to improve the performance.
