CryptoJS AES 加密（密钥大小 128 / 8）相当于 PHP

发布于 2025-01-10 14:26:26 字数 1712 浏览 1 评论 0原文

我是 PHP 新手，我试图在 PHP 中实现与 CryptoJS AES 加密等效的功能。我看到了这篇帖子，但不幸的是我无法实现相同的目标。我在 PHP 代码中得到了不同的输出作为加密字符串。

我哪里做错了？

Javascript代码

const customerObject = {
  CustomerName: "test",
  EmailID: "[email protected]",
  Street: "Test",
  City: "London",
  Country: "United Kingdom",
  ZipCode: "XXX XXX",
};

const token = "8056483646328123";

const key = CryptoJS.enc.Utf8.parse(token);
const iv = CryptoJS.enc.Utf8.parse(token);

const returnEncrypted = CryptoJS.AES.encrypt(
  CryptoJS.enc.Utf8.parse(customerObject),
  key,
  {
    iv: iv,
    keySize: 128 / 8,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7,
  }
);

PHP代码

 <?php
    
    $customer = [
       'CustomerName' => "test",
       'EmailID' => "[email protected]",
       'Street' => "Test",
       'City' => "London",
       'Country' => "United Kingdom",
       'ZipCode' => "XXX XXX",
    ];
    
    
    $plaintext  = json_encode($customer);
    $method     = 'AES-128-CBC';
    
    $key = hex2bin("8056483646328123");
    $iv  = hex2bin("8056483646328123");
    
    $ciphertext = openssl_encrypt(
       $plaintext,
       $method,
       $key,
       OPENSSL_RAW_DATA,
       $iv
    );
    
    
    $ciphertext = base64_encode($ciphertext);

    echo $ciphertext;
    
    ?>

I am newbie in PHP and I was trying to achieve the CryptoJS AES encryption equivalent in PHP. I saw this post but unfortunately I was not able to achieve the same. I was getting a different output in PHP code as encrypted string.

Where did I go wrong?

Javascript Code

const customerObject = {
  CustomerName: "test",
  EmailID: "[email protected]",
  Street: "Test",
  City: "London",
  Country: "United Kingdom",
  ZipCode: "XXX XXX",
};

const token = "8056483646328123";

const key = CryptoJS.enc.Utf8.parse(token);
const iv = CryptoJS.enc.Utf8.parse(token);

const returnEncrypted = CryptoJS.AES.encrypt(
  CryptoJS.enc.Utf8.parse(customerObject),
  key,
  {
    iv: iv,
    keySize: 128 / 8,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7,
  }
);

PHP Code

 <?php
    
    $customer = [
       'CustomerName' => "test",
       'EmailID' => "[email protected]",
       'Street' => "Test",
       'City' => "London",
       'Country' => "United Kingdom",
       'ZipCode' => "XXX XXX",
    ];
    
    
    $plaintext  = json_encode($customer);
    $method     = 'AES-128-CBC';
    
    $key = hex2bin("8056483646328123");
    $iv  = hex2bin("8056483646328123");
    
    $ciphertext = openssl_encrypt(
       $plaintext,
       $method,
       $key,
       OPENSSL_RAW_DATA,
       $iv
    );
    
    
    $ciphertext = base64_encode($ciphertext);

    echo $ciphertext;
    
    ?>

正如 @Topaco 在评论中指出的，key 和 IV不得进行十六进制解码，即删除两个 hex2bin()。

更正后的代码如下。

<?php
    
    $customer = [
       'CustomerName' => "test",
       'EmailID' => "[email protected]",
       'Street' => "Test",
       'City' => "London",
       'Country' => "United Kingdom",
       'ZipCode' => "XXX XXX",
    ];
    
    
    $plaintext  = json_encode($customer);
    $method     = 'AES-128-CBC';
    
    $key = "8056483646328123";
    $iv  = "8056483646328123";
    
    $ciphertext = openssl_encrypt(
       $plaintext,
       $method,
       $key,
       OPENSSL_RAW_DATA,
       $iv
    );
    
    
    $ciphertext = base64_encode($ciphertext);

    echo $ciphertext;
    
    ?>

As @Topaco pointed out in comments, the key and IV must not be hex decoded, i.e. remove both hex2bin().

The corrected code is given below.

<?php
    
    $customer = [
       'CustomerName' => "test",
       'EmailID' => "[email protected]",
       'Street' => "Test",
       'City' => "London",
       'Country' => "United Kingdom",
       'ZipCode' => "XXX XXX",
    ];
    
    
    $plaintext  = json_encode($customer);
    $method     = 'AES-128-CBC';
    
    $key = "8056483646328123";
    $iv  = "8056483646328123";
    
    $ciphertext = openssl_encrypt(
       $plaintext,
       $method,
       $key,
       OPENSSL_RAW_DATA,
       $iv
    );
    
    
    $ciphertext = base64_encode($ciphertext);

    echo $ciphertext;
    
    ?>
