PHP7实现和CryptoJS的AES加密方式互通示例【AES-128

class AES
{
  /**
   *
   * @param string $string 需要加密的字符串
   * @param string $key 密钥
   * @return string
   */
  public static function encrypt($string, $key)
  {
    // openssl_encrypt 加密不同Mcrypt，对秘钥长度要求，超出16加密结果不变
    $data = openssl_encrypt($string, 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
    return base64_encode($data);
  }
  /**
   * @param string $string 需要解密的字符串
   * @param string $key 密钥
   * @return string
   */
  public static function decrypt($string, $key)
  {
    return openssl_decrypt(base64_decode($string), 'AES-128-ECB', $key, OPENSSL_RAW_DATA);
  }
  /**
   * 获取秘钥
   * @return string
   */
  public static function getSecretKey()
  {
    $str='xxx';//生成16位的字符窜
    return $str;
  }
}

<script type="text/javascript" src="./bower_components/crypto-js/crypto-js.js"></script>
<script type="text/javascript">
  AesKey = 'xxxxx';//加密时用的key,跟php一样
  message='xxxxxxx';//加密后的字符窜
  var ECBOptions = {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
  };
  var key = CryptoJS.enc.Utf8.parse(AesKey);
  var bytes = CryptoJS.AES.decrypt(message, key,ECBOptions);
  var originalText = bytes.toString(CryptoJS.enc.Utf8);
  console.log(originalText)
