今天在写一个压测工具的时候。试运行的时候发现了一个报错
Traceback (most recent call last):
File "/.../path/test.py", line 5, in <module>
from Crypto.Cipher import AES
ModuleNotFoundError: No module named 'Crypto'因为我这边压测的接口都是加密请求，需要使用到AES-ECB加密
理所当然的在这个时候我理所当然的执行了
python3 -m pip install Crypto执行如下

Installing collected packages: pyyaml, shellescape, Naked, Crypto
Successfully installed Crypto-1.4.1 Naked-0.1.31 pyyaml-6.0 shellescape-3.8.1然后执行依然是相同的报错。我很奇怪就百度查了资料，然后又执行了
python3 -m pip install pycrypto
python3 -m pip install pycryptodomex结果报错依旧。我吐了 接着查询。又听了某些人说修改site-packages文件夹下面的crypto文件夹名字为Crypto。
然后还是报错。我没办法了。继续google里面查找资料
终于找到一篇文章Stop using pycrypto. Use pycryptodome instead
就如文章中所说
Pycrypto is vulnerable to a heap-based buffer overflow in the ALGnew function in block_templace.c. It allows remote attackers to execute arbitrary code in the python application. It was assigned the CVE-2013-7459 number.
Pycrypto didn’t release any fix to that vulnerability and no commit was made to the project since Jun 20, 2014.
意思就是:
Pycrypto 容易受到 block_templace.c 中 ALGnew 函数中基于堆的缓冲区溢出的影响。它允许远程攻击者在 python 应用程序中执行任意代码。它被分配了CVE-2013-7459编号。
自 2014 年 6 月 20 日以来，Pycrypto 没有发布对该漏洞的任何修复程序，也没有对该项目进行任何提交。
所以最终得到的解决方案就是
请卸载的所有版本crypto和pycrypto，并且安装pycryptodome：
python3 -m pip uninstall crypto
python3 -m pip uninstall pycrypto
python3 -m pip uninstall pycryptodomex
python3 -m pip install pycryptodome
