win10下python3 Crypto.Util.number模块下载问题解决方法

**
首先感谢大佬的博客启发：
https://blog.csdn.net/wukai0909/article/details/109772278

在最近的CISCN2021中在crypto上十分挫败，在赛后查看相关大佬的题解才发现要使用相关的模块
就像下图这样：

from Crypto.Util.number import getStrongPrime, bytes_to_long
from flag import flag

可是我在使用

pip install crypto

提示出错，就在网上疯狂寻找相关方法，为此我还把python3.9和python2.7以及pycharm卸载重装了一遍，功夫不负有心人，我终于找到了相关方法：

1.首先是安装大佬博客中所说

pip3 install pyCryptodome -i https://pypi.douban.com/simple

crypto已经停用，不再更新。而pycryptodome则可以完美替代它，相应的子模块也都有，故安装pycryptodome模块即可。
2.但是在pycharm中依旧无法调用，在cmd窗口也无法调用

3. 但是我发现我调用的是crypto，结果显示Crypto出错，在对应路径下是crypto出错，所以我想到之前在检索时发现可以修改site-packages目录下的crypto文件夹大小写，改为Crypto.此时再次调用便不报错：

同时在pycharm中也不再报错：

import gmpy2
from Crypto.Util.number import long_to_bytes
n = 544187306850902797629107353619267427694837163600853983242783
e = 39293
c = 439254895818320413408827022398053685867343267971712332011972
p1 = 67724172605733871
p2 = 11571390939636959887
p3 = 694415063702720454699679
phi = (p1 - 1) * (p2 - 1) * (p3 - 1)
d = gmpy2.invert(e, phi)
m = pow(c, d, n)
print
long_to_bytes(m)

4.同时我发现大佬博客中的语句也可以改为相应的模块，同样适用：

5.但是我仍未解决hashkib模块的安装方法，直到我意识到hashlib是python3的内置模块。
6.抱歉，我又发现了问题无法解决，hmac极度不稳定

python内置还有一个 hmac 模块，它内部对我们创建 key 和 内容 进行进一步的处理然后再加密：

import hmac
h = hmac.new(bytes('898oaFs09f',encoding="utf-8"))
h.update(bytes('admin',encoding="utf-8"))
print(h.hexdigest())

但是它会报错：

Traceback (most recent call last):
  File "D:\Pycharm\Programs\function1\main.py", line 105, in <module>

经过检索后发现疑似与版本的不兼容问题导致，可参考：
