php 如何从 flutter 中解密 aes 加密

Question

在我的 flutter 应用程序中，我使用了一个名为 encrypt 的加密包。并且能够使用此代码加密我的聊天消息

import 'package:encrypt/encrypt.dart';

class TextEncrypt {
  final _iv = IV.fromLength(16);
  final key = Key.fromLength(32);

  String decrypt(String text) {
    final enc = Encrypter(AES(key));
    final encrypted = Encrypted.fromBase64(text);
    return enc.decrypt(encrypted, iv: this._iv);
  }

  String encrypt(String text) {
    final enc = Encrypter(AES(key));
    return enc.encrypt(text, iv: _iv).base64;
  }
}

但问题是加密的部分将存储在 mysql 数据库中，并且也会在本地数据库 (sqflite) 中运行，当我想使用 [=24] 为应用程序构建网站时=] mysql html css javascript。我将如何使用 php 将其解密回其正常文本，或者您认为可能有更好的方法在应用程序中加密它并且还能够在 php 中解密它从这个方法

如果您不明白我在说什么，需要更多解释，请告诉我

这是可以帮助您的示例：

颤振代码：

import 'package:encrypt/encrypt.dart';

String decrypt(String encrypted) {
  final key = Key.fromUtf8("1245714587458888"); //hardcode combination of 16 character
  final iv = IV.fromUtf8("e16ce888a20dadb8"); //hardcode combination of 16 character

  final encrypter = Encrypter(AES(key, mode: AESMode.cbc));
  Encrypted enBase64 = Encrypted.from64(encrypted);
  final decrypted = encrypter.decrypt(enBase64, iv: iv);
  return decrypted;
}

String encrypt(String value) {
  final key = Key.fromUtf8("1245714587458745"); //hardcode 
  final iv = IV.fromUtf8("e16ce888a20dadb8"); //hardcode 

  final encrypter = Encrypter(AES(key, mode: AESMode.cbc));
  final encrypted = encrypter.encrypt(value, iv: iv);

  return encrypted.base64;
}

和 PHP 代码：（启用 openssl.dll 扩展）

function encrypt($value){
    $key = '1245714587458888'; //combination of 16 character
    $iv = 'e16ce888a20dadb8'; //combination of 16 character
    $method = 'aes-128-cbc';
    $encryptedString = openssl_encrypt($value, $method,
        $key, OPENSSL_RAW_DATA, $iv);
    return base64_encode($encryptedString);
}

function decrypt($value){
    $key = '1245714587458888'; //combination of 16 character
    $iv = 'e16ce888a20dadb8'; //combination of 16 character
    $method = 'aes-128-cbc';
    $base64 = base64_decode($value);
    $decryptedString = openssl_decrypt($base64, $method,
        $key, OPENSSL_RAW_DATA, $iv);
    return $decryptedString;
}
