python-3.x - 获取异常：对象类型不能传递给 C 代码

Question

我在 Python 3.7.2 上安装pip install pycryptodome 。我遇到了obj = AES.new(key, AES.MODE_CBC, iv)行的异常。我的代码是：

from Crypto import Random
from Crypto.Cipher import AES
import random

def get_encryption():
    try:
        str = "This is input string"

        key = b'abcdefghijklmnop'  
        iv = Random.new().read(AES.block_size)

        obj = AES.new(key, AES.MODE_CBC, iv)
        encrypted = obj.encrypt(str)
        print(encrypted)
    except Exception as e:
        print(e)

我一直尝试但没有得到解决方法。

在尝试了所有方法后，我得到了解决方案。我将密钥字符串转换为字节。代码是：

from Crypto import Random
from Crypto.Cipher import AES
import random

def get_encryption():
    try:
        strmsg = "This is input string"

        key = 'abcdefghijklmnop'  
        key1 = str.encode(key)

        iv = Random.new().read(AES.block_size)

        obj = AES.new(key1, AES.MODE_CBC, iv)
        encrypted = obj.encrypt(str.encode(strmsg))
        print(encrypted)
    except Exception as e:
        print(e)
