MySQL - Navicat解析MySQL密码 - 《clown》

使用navicat导出连接配置
打开配置，查看密码
访问此网址https://tool.lu/coderunner/
使用加密的密码更改 $navicatPassword->decrypt(‘15057D7BA390’) 此处密码，点击运行 ```php <?php namespace FatSmallTools; class NavicatPassword { protected $version = 0; protected $aesKey = ‘libcckeylibcckey’; protected $aesIv = ‘libcciv libcciv ‘; protected $blowString = ‘3DC5CA39’; protected $blowKey = null; protected $blowIv = null;
