navicat如何查看数据库密码？

navicat 用久了有些数据库连接密码忘记了，怎么办？

软件提供了导出链接功能：

文件----导出链接----记得勾选导出密码

打开文件，查看密码字段

需要解密使用

解密 - 使用PHP程序进行解密

<?php// Navicat 11及以前的版本
//$navicatPassword = new NavicatPassword(11);// Navicat 12及以后的版本
$navicatPassword = new NavicatPassword(12);$decode = $navicatPassword->decrypt('9F6B3EE5AE4F53AD8EA70079846F73EDE5B83C29B148BF77DFA988BCCDC3A918');
echo $decode . "\n";class NavicatPassword
