加密方式:

这一块主要是不同的版本不同的加密方法，大家可自行研究相关的加密方式，这里不过多讲解：

https://github.com/HyperSine/how-does-Xmanager-encrypt-password

xshell路径

xshell 5%userprofile%DocumentsNetSarangXshellSessions
xshell 6%userprofile%DocumentsNetSarang Computer6XshellSessions
xshell 7%userprofile%DocumentsNetSarang Computer7XshellSessions

xftp路径

xftp5%userprofile%DocumentsNetSarangXshellSessions
XFtp6    %userprofile%DocumentsNetSarang Computer6XftpSessions
XFtp7%userprofile%DocumentsNetSarang Computer7XftpSessions

破解

我们来看一下xshell7其存储格式，其保存为.xsh格式

如何获取Xshell/xftp密码

直接使用sublime打开，可以看到其密码字段为password

如何获取Xshell/xftp密码

这里面就是我们要破解的密码，直接上工具，使用下面语法：

python XShellCryptoHelper.py -d -ver 7.0 passsword

可以直接获取到相关的密码：

如何获取Xshell/xftp密码

注：xftp密码一样的获取方式。
