报错解决：TypeError: Object type class 'str' cannot be passed to C code

此文首发于我的个人博客：报错解决 TypeError Object type class ‘str’ cannot be passed to C code — zhang0peter的个人博客

下午在使用Crypto的时候报错如下:

Traceback (most recent call last):File "/usr/lib64/python3.6/multiprocessing/pool.py", line 119, in workerresult = (True, func(*args, **kwds))File "/usr/lib64/python3.6/multiprocessing/pool.py", line 44, in mapstarreturn list(map(*args))File "FastFinally.py", line 86, in generate2next(yield_32),next(yield_32)File "FastFinally.py", line 55, in AES_32_YIELDyield int(aes.encrypt(data).hex(),16)File "/usr/local/lib64/python3.6/site-packages/pycryptodome-3.9a0-py3.6-linux-x86_64.egg/Crypto/Cipher/_mode_ctr.py", line 201, in encryptc_uint8_ptr(plaintext),File "/usr/local/lib64/python3.6/site-packages/pycryptodome-3.9a0-py3.6-linux-x86_64.egg/Crypto/Util/_raw_api.py", line 235, in c_uint8_ptrraise TypeError("Object type %s cannot be passed to C code" % type(data))
TypeError: Object type <class 'str'> cannot be passed to C code
"""The above exception was the direct cause of the following exception:Traceback (most recent call last):File "FastFinally.py", line 97, in <module>pool.map(generate2,l)File "/usr/lib64/python3.6/multiprocessing/pool.py", line 266, in mapreturn self._map_async(func, iterable, mapstar, chunksize).get()File "/usr/lib64/python3.6/multiprocessing/pool.py", line 644, in getraise self._value
TypeError: Object type <class 'str'> cannot be passed to C code

我的代码如下：

from Crypto.Cipher import AES
from Crypto.Util import Counter
import os
key=os.urandom(16)
aes = AES.new(key, AES.MODE_CTR, counter=Counter.new(128))
data = "0" * 8
temp=aes.encrypt(data)

这部分代码在Windows上跑没问题，但是到Linux上跑就出错了。

把代码修改如下：

temp=aes.encrypt(data.encode('utf-8'))

只能说坑真多
