Windows下给IDApro 安装yara-python 和findcrypt

https://blog.csdn.net/szxpck/article/details/107203718

目标：在IDA pro7.0上安装findcrypt这个插件。

而findcrypt这个插件需要依赖python的yara-python模块。因此先安装yara-python。

因为要用到pip安装，并且是给IDA自带的python安装模块。所以事先需要把当前python2的环境变量修改为IDA使用的python2.

修改完成后pip -V 就能查看当前使用的pip信息

然后使用pip install yara-python 报各种乱七八糟的错。

C:\Users\ygt>python -m pip install yara-python

在查阅了

https://blog.csdn.net/fjh1997/article/details/107167704/

的博客之后才知道，要想安装成功，需要限定wheel的版本——只有3.11的轮子支持python2，而且是windows版本。

因此使用

python -m pip install yara-python==3.11.0

• 1

如果提示：
Using legacy setup.py install for yara-python, since package 'wheel' is not installed.

可以使用
python -m pip install wheel安装wheel模块。

yara-python安装好后，去https://github.com/polymorf/findcrypt-yara 将下载好的 findcrypt3.py 和findcrypt3.rules拷贝到 IDA\plugins 目录。随后打开IDA，随便拖入一个程序，就可以在edit-plugins里面找到Findcrypt这个插件了。

Findcrypt可以很有效地识别许多公开的加密算法。有效避免了把过多的时间花费在阅读加密代码上。当然了如果是自定义的加密函数肯定还是只有手撸的
