在python3.6上安装pycrypto

pip install pycryptodome

from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes
from Crypto.Util.Padding import pad, unpad

# 生成密钥
key = get_random_bytes(16)

# 创建AES加密对象
cipher = AES.new(key, AES.MODE_CBC)

# 要加密的数据
data = b'This is a secret message'

# 填充数据
padded_data = pad(data, AES.block_size)

# 加密数据
iv = cipher.iv
encrypted_data = cipher.encrypt(padded_data)

print(f'Encrypted data: {encrypted_data}')

# 创建AES解密对象
cipher_dec = AES.new(key, AES.MODE_CBC, iv)

# 解密数据
decrypted_padded_data = cipher_dec.decrypt(encrypted_data)

# 去除填充
decrypted_data = unpad(decrypted_padded_data, AES.block_size)

print(f'Decrypted data: {decrypted_data.decode()}')
