How to Password Protect Files Using Python

Password Protect Files Using Python

As the digital world evolves, the need for securing our files and data becomes more crucial. One effective way to enhance the security of your files is by password protecting them using Python programming language.

Python provides various libraries and modules that offer encryption and password protection functionalities. One popular library is cryptography, which allows users to implement encryption and decryption techniques easily.

Here's a simple guide to password protect files using Python:

1. Install the cryptography library by running: pip install cryptography
2. Create a Python script and import the necessary modules:

from cryptography.fernet import Fernet

# Generate a key
key = Fernet.generate_key()

# Create a Fernet symmetric key
cipher_suite = Fernet(key)

3. Specify the file you want to encrypt and the password to protect it:

file_path = 'file_to_protect.txt'

# Read the file content
with open(file_path, 'rb') as file:
    original_content = file.read()

# Encrypt the file content
encrypted_content = cipher_suite.encrypt(original_content)

4. Write the encrypted content back to the file:

with open(file_path, 'wb') as file:
    file.write(encrypted_content)

5. Now, your file is password protected using Python!

Remember to store your encryption key securely as it will be required for decryption. By following these steps, you can enhance the security of your sensitive files and data with just a few lines of Python code.
