SecureCRTSecure7.0查看连接密码的步骤

整体分为两步：

第一步：查看系统保存的连接的ini文件(大概位置：F:\SecureCRTSecureFX_HH_x64_7.0.0.326\Data\Settings\Config\Sessions)

ini文件的格式样例：

1. —ip地址
2. S:“Hostname”=192.168.0.145
3. –登录用户
4. S:“Username”=root
5. –端口，加密
6. D:“[SSH2] 端口”=00000016
7. –密码，加密，解密需要u之后的字符串
8. S:“Password”=u2c7d50aae53e14eb94ef0cb377c247a77c2dbcea95333365

第二步：破解加密之后的密码，这个使用python3，具体脚本如下：

将上面的python代码保存为：SecureCRTCipher.py，使用分为两种情况：

第一种：

密码的格式如下：

S:”PasswordV2″=02:7b9f594a1f39bb36bbaa0d9688ee38b3d233c67b338e20e2113f2ba4d328b6fc8c804e3c02324b1eaad57a5b96ac1fc5cc1ae0ee2930e6af2e5e644a28ebe3fc

执行脚本：

python SecureCRTCipher.py dec -v2 7b9f594a1f39bb36bbaa0d9688ee38b3d233c67b338e20e2113f2ba4d328b6fc8c804e3c02324b1eaad57a5b96ac1fc5cc1ae0ee2930e6af2e5e644a28ebe3fc

第二种：

密码的格式如下：

S:”Password”=uc71bd1c86f3b804e42432f53247c50d9287f410c7e59166969acab69daa6eaadbe15c0c54c0e076e945a6d82f9e13df2

执行脚本：注意密码的字符串去掉u

python SecureCRTCipher.py dec c71bd1c86f3b804e42432f53247c50d9287f410c7e59166969acab69daa6eaadbe15c0c54c0e076e945a6d82f9e13df2

执行上述脚本，python需要安装pycryptodome模块，安装脚本：

1. pip install pycryptodome
