How can I decrypt files in different programming languages?

You can decrypt files using various programming languages like Python, Java, and C#. Which language are you interested in?

Let's start with Python. How do I do that?

In Python, you can use libraries like cryptography or PyCrypto. Do you have a specific encryption method in mind?

I want to decrypt AES encrypted files.

You can use the Fernet module from the cryptography library for AES. Here's a basic example: from cryptography.fernet import Fernet.

Can you provide a complete code example?

Sure! Here's a simple example:

from cryptography.fernet import Fernet

# Load your key
key = b'your_key_here'
fernet = Fernet(key)

# Read the encrypted file
with open('encrypted_file', 'rb') as file:
    encrypted_data = file.read()

# Decrypt the data
decrypted_data = fernet.decrypt(encrypted_data)

# Save the decrypted data
with open('decrypted_file', 'wb') as file:
    file.write(decrypted_data)
