crypto-js与php aes加密传输

CryptoJS (crypto.js) 为 JavaScript 提供了各种各样的加密算法。目前已支持的算法包括：

• MD5
• SHA-1
• SHA-256
• AES
  ....
  这里我们演示aes对称加密数据传输，下面列出crypto-js的几个重要链接

        return json_decode(base64_decode($decrypted), true);
    }

$data = ['username'=>'admin','pwd'=>'admin'];  
$encrypt=encrypt($data);
$str=decrypt($encrypt);
var_dump($str);
