時間久了，當(dāng)我們以前連上了navicat 之后，密碼忘記了，但是依然能連接，此時我們想查看密碼，應(yīng)該如何操作呢？

步驟1：點擊navicat 文件選項，導(dǎo)出連接，勾選需要導(dǎo)出的數(shù)據(jù)庫，導(dǎo)出的時候一定要勾選導(dǎo)出密碼

導(dǎo)出之后，我們會得到一個connections.ncx文件中找到password，然后復(fù)制出來

復(fù)制出來password內(nèi)容

然后我們要對這個password 密碼進行解密。打開小工具 網(wǎng)站：

將如下PHP代碼復(fù)制進去：

//需要指定版本兩種，11或12
//$navicatPassword = new NavicatPassword(11);
//這里我指定的12的版本，原先指定的11，執(zhí)行之后的密碼是亂碼
$navicatPassword = new NavicatPassword(12);
 
//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('AE137B98AB3AD0F913EBEF2E8D3C52E9');
echo $decode."\n";
?>

點擊執(zhí)行，右邊運行得到密碼。

方法2：可以使用python 代碼。
