win10 python3.7 安装 pycrypto2.6.1遇到的问题及生成大素数
win10 python3.7 安装 pycrypto2.6.1生成大素数.
1.安装pycrypto
pip install pycrypto如果安装没有出现错误,关闭页面直接进入代码阶段.出现下面内容即为成功
running install_egg_info安装pycrypto遇到的问题:
- 首先是遇到常见error，缺少C++组件：
报错内容：Microsoft Visual C++ 14.0 is required.
报错原因：组件缺失
解决办法：使用下面下载链接下载Microsoft Visual C++ 14.0安装就ok

error: command ‘C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe‘ failed with exit status 2解决办法: 1.找到你Microsoft Visual Studio 14.0的安装路径,我的是
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include复制stdint.h到下一步的路径中
2.把上一步复制的文件粘贴在下图路径中,我的路径为
C:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\ucrt该处的路径即为第二种问题报错路径
3.修改报错地址的inttypes.h文件，#include
重新安装,显示running install_egg_info即安装成功.
- 引用库时,注意大小写Crypto还是crypto
安装成功之后使用库
from crypto.PublicKey import RSA
if __name__ == '__main__':
RsaKey = RSA.generate(2048)
print(RsaKey.p)
print(hex(RsaKey.p))
print(len(hex(RsaKey.p)))
print("#################")
print(RsaKey.q)
print(hex(RsaKey.q))
print(len(hex(RsaKey.q)))
运行代码报错,修改引用
from Crypto.PublicKey import RSA并在python目录下,我的目录
D:\ocean\application\python3.7\Lib\site-packages修改crypto为Crypto,运行无误

258使用RSA库生成2048位秘钥时素数p.q时,p为136字节,q为120字节.查看源码注释,是为了两个素数不相近.
我们的需求是只能生成128字节的素数.上图中258为p.q转化为hex时,包含0x的长度.
至此,可以生成128字节素数.
