解决方法
目录
一:通过注册表找到数据库连接的密码,再通过PHP解密
具体操作:
用 win + R 快捷键打开运行窗口,输入 regedit 打开注册表
在注册表地址栏输入下面内容,查找Navicat密码保存位置,回车:
计算机\HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\Navicat\Servers
在servers目录下,找到需要找回密码的连接,鼠标左键点击,右侧下拉找到名称为 pwd 的一项,该项的数据即为密码。右键,点击修改,复制数据:
4.使用 https://tool.lu/coderunner/
在线工具,对复制下来的密码15057D7BA390进行解密
将以下php解密代码复制到在线工具中,将复制的数据粘贴到代码的倒数第二行,点击执行,即可得到密码
PS:该工具首行不能空行,否则执行会报错;另外,在代码倒数五六行需要指定Navicat版本

return openssl_decrypt($string, 'AES-128-CBC', $this->aesKey, OPENSSL_RAW_DATA, $this->aesIv);
}
}use FatSmallTools\NavicatPassword;
//需要指定版本,11或12
//$navicatPassword = new NavicatPassword(12);
$navicatPassword = new NavicatPassword(11);//解密
$decode = $navicatPassword->decrypt('15057D7BA390');
echo $decode."\n";
二:通过Navicat导出连接,找到连接密码,再通过PHP进行解密
具体操作:
打开Navicat,导航栏点击“文件”,点击“导出连接”,
选择自己需要找回密码的连接,并勾选左下角“导出密码”,点击“确定”
3.打开导出的文件,找到Password这一项,将引号中的数据复制下来
打开并使用方法一步骤4.中的在线工具和代码,修改倒数第二行的内容为步骤三保存的数据833E4ABBC56C89041A9070F043641E3B,点击运行
PS:由于我使用的是Navicat 12,在这种方法中需要修改代码中倒数第五六行的版本,否则解析出来乱码
