pycharm实现AES子密钥生成算法完整代码

下面是实现AES子密钥生成算法的完整代码，使用Python语言编写，需要安装pycryptodome库：

from Crypto.Util import Counter
from Crypto.Util import strxor

if __name__ == '__main__':
    main()

在main函数中，先定义了一个128位的密钥，然后调用key_expansion函数生成44个轮密钥，最后遍历这44个轮密钥输出。

其中，rot_word函数实现了字循环移位操作，sub_word函数实现了字节代换操作，key_expansion函数实现了AES的密钥扩展算法；aes_encrypt和aes_decrypt函数分别实现了AES的加密和解密操作。
