JS 解密 Laravel 加密字符串

Question

我必须laravel 6用 JavaScript 解密加密的字符串。输入 laravel.env文件

APP_KEY=base64:Rva4FZFTACUe94+k+opcvMdTfr9X5OTfzK3KJHIoXyQ=

并且在config/app.php文件密码中设置为以下...

APP_KEY=base64:Rva4FZFTACUe94+k+opcvMdTfr9X5OTfzK3KJHIoXyQ=

到目前为止我所尝试过的如下......

Laravel 代码

'cipher' => 'AES-256-CBC',

HTML 和 JavaScript 代码

$test = 'this is test';
$encrypted = Crypt::encrypt($test);

上述代码的控制台输出如下屏幕截图所示...

我已经尝试了来自谷歌和堆栈溢出的许多其他 JS 代码，但没有运气。

更新

这是在单独的离线系统中解密字符串的要求。我不会在实时网站上使用 javascript 进行加密。相反，用java脚本解密将在离线系统上完成。

Answer 1

这是使用 AES-256-CBC 作为密码解密使用 Laravel 编码的 javascript 文本的方法。

使用 CryptoJS 4.0...
