How do I implement AES encryption in Python?

You can use the pycryptodome library to implement AES encryption in Python. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
import os

key = os.urandom(16)  # AES key must be either 16, 24, or 32 bytes long
cipher = AES.new(key, AES.MODE_CBC)

plaintext = b'This is a secret message.'

# Encrypting
ciphertext = cipher.encrypt(pad(plaintext, AES.block_size))

# Decrypting
cipher = AES.new(key, AES.MODE_CBC, cipher.iv)
decrypted = unpad(cipher.decrypt(ciphertext), AES.block_size)
print(decrypted)

What do I need to install to run this code?

You need to install the pycryptodome library. You can do this using pip:

pip install pycryptodome
