How to Create an Encrypted ZIP File in Python Using ZipFile Module

Creating encrypted ZIP files in Python can be an essential part of securing your data. In this guide, we will explore how to create an encrypted ZIP file using Python's ZipFile module.

Before diving into the code, it's important to note that ZipFile module itself does not support encryption natively. Therefore, we'll use the pyzipper module, which extends zipfile and adds support for strong encryption.

Prerequisites

To follow along with this guide, you'll need the following:

Basic understanding of Python.

Installed Python interpreter (version 3.6 or above).

Install the pyzipper library using pip:

Step-by-Step Guide

Step 1: Import Required Modules

First, we need to import the necessary modules: os for file operations and pyzipper for working with ZIP files.

Step 3: Create the Encrypted ZIP File

Now, we will create the ZIP file and add the specified files. We will use AES256 encryption for better security.

Explanation

AESZipFile: This class is part of pyzipper and is used for creating encrypted ZIP files.

'w': Indicates write mode. It will create a new ZIP file, overwriting any existing file with the same name.

compression=pyzipper.ZIP_LZMA: Specifies the compression method. LZMA offers a good balance between speed and compression ratio.

setpassword(password): Sets the password to be used for encrypting the files.

setencryption(pyzipper.WZ_AES, nbits=256): Specifies that AES encryption will be used with a 256-bit key.

os.path.basename(file): Ensures that only the filename is stored in the ZIP archive, not the full path.

Conclusion

By following this guide, you should be able to create an encrypted ZIP file in Python using the ZipFile module with the help of pyzipper. This method ensures that your sensitive data is secure and protected from unauthorized access. Always remember to use a strong password for encryption to maximize security.

Happy coding!
