Step 1: Install the necessary package

pip install cryptography

Step 2: Import the required modules

from cryptography.hazmat.backends import default_backend
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes

Step 3: Generate a random initialization vector (IV)

from os import urandom
iv = urandom(16)

Step 4: Create a cipher object with AES algorithm and CBC mode

backend = default_backend()
cipher = Cipher(algorithms.AES(key), modes.CBC(iv), backend=backend)

Step 5: Create an encryptor object

encryptor = cipher.encryptor()

Step 6: Encrypt the plaintext

ciphertext = encryptor.update(plaintext) + encryptor.finalize()

Step 7: Create a decryptor object

decryptor = cipher.decryptor()

Step 8: Decrypt the ciphertext

decrypted_text = decryptor.update(ciphertext) + decryptor.finalize()

Note: Ensure that the 'key' variable is a valid AES key (16, 24, or 32 bytes). The 'plaintext' variable should be the data you want to encrypt. The 'ciphertext' variable will contain the encrypted data, and 'decrypted_text' will contain the decrypted data.
