Auto unzip of password protected rar files in python

Python provides several ways to unzip password protected rar files. In this article, we will explore three different methods to achieve this.

Method 1: Using the rarfile library

The rarfile library is a Python module that allows us to work with rar files. To install it, we can use the following command:

!pip install rarfile

Once installed, we can use the following code to unzip a password protected rar file:

import rarfile

def unzip_rar(file_path, password):
    with rarfile.RarFile(file_path) as rf:
        rf.extractall(pwd=password)

In the above code, we first import the rarfile module. Then, we define a function unzip_rar that takes the file path and password as parameters. Inside the function, we use the RarFile class from the rarfile module to open the rar file. We then call the extractall method on the RarFile object, passing the password as the pwd parameter.

Method 2: Using the zipfile library

The zipfile library is a built-in module in Python that allows us to work with zip files. Although it doesn’t directly support rar files, we can still use it to unzip password protected rar files by converting them to zip format. To install it, we can use the following command:

!pip install rarfile

Once installed, we can use the following code to unzip a password protected rar file:

import zipfile
import rarfile

def unzip_rar(file_path, password):
    with rarfile.RarFile(file_path) as rf:
        rf.extractall(pwd=password)

def convert_to_zip(file_path):
    zip_path = file_path.replace('.rar', '.zip')
    with zipfile.ZipFile(zip_path, 'w') as zf:
        zf.write(file_path)

    return zip_path

def unzip_zip(file_path, password):
    with zipfile.ZipFile(file_path) as zf:
        zf.extractall(pwd=password)

def unzip_password_protected_rar(file_path, password):
    convert_to_zip(file_path)
    unzip_zip(file_path.replace('.rar', '.zip'), password)

In the above code, we first import the zipfile and rarfile modules. Then, we define three functions: unzip_rar, convert_to_zip, and unzip_zip. The unzip_rar function is the same as in Method 1. The convert_to_zip function converts the rar file to zip format by creating a new zip file and adding the contents of the rar file to it. The unzip_zip function extracts the contents of the zip file. Finally, the unzip_password_protected_rar function combines the above functions to unzip the password protected rar file.

Method 3: Using the patool library

The patool library is a Python module that provides a high-level interface for working with various archive formats, including rar files. To install it, we can use the following command:

!pip install patool

Once installed, we can use the following code to unzip a password protected rar file:

import patoolib

def unzip_rar(file_path, password):
    patoolib.extract_archive(file_path, password=password)

In the above code, we import the patoolib module. Then, we define a function unzip_rar that takes the file path and password as parameters. Inside the function, we use the extract_archive function from the patoolib module to extract the contents of the rar file, passing the password as the password parameter.

After exploring the three methods, it is evident that Method 1 using the rarfile library is the most straightforward and efficient way to unzip password protected rar files in Python. It doesn’t require any additional conversion steps and provides a clean and concise solution.

  1. I cant believe were still talking about unzipping password-protected files manually. Cant technology just handle this for us already? #LazyTech
