Question

在网络上尝试了很多例子，但我在C＃中得不到与PHP相同的结果。

我有一个C＃Web服务，它将接收我需要解密的加密字符串。该字符串已使用类似下面的代码在PHP中加密。当输入字符串为“1234”时，此PHP代码将输出“eGtLMUc5cXdEblY2dHhDVUhjcm56Zz09”。然后我尝试用C＃解密它，但无法做到这一点，尝试了我能找到的每个例子，但我的输出总是不同于“1234”（大多数情况下只是一堆随机字母/数字）。

输入：1234

输出：eGtLMUc5cXdEblY2dHhDVUhjcm56Zz09

<?php
$secret_key = 'verySecretKey';
$secret_iv = 'secret_iv_string';
$key = hash('sha256', $secret_key);
$iv = substr(md5(md5($secret_iv)), 0, 16);
$method = 'AES-256-CBC';
$inputString = '1234';

$encrypted = openssl_encrypt($inputString, $method, $key,FALSE,$iv);
echo base64_encode($encrypted);
?>

我可以使用下面的代码在PHP中解密它。

输入：eGtLMUc5cXdEblY2dHhDVUhjcm56Zz09

输出：1234

<?php
$encryptedString = 'eGtLMUc5cXdEblY2dHhDVUhjcm56Zz09';
$encrypt_method = 'AES-256-CBC';
$secret_key = 'verySecretKey';
$secret_iv = 'secret_iv_string';
$key = hash('sha256', $secret_key);
$iv = substr(md5(md5($secret_iv)), 0, 16);
$plain_password = openssl_decrypt(base64_decode($encryptedString), $encrypt_method, $key, FALSE, $iv);
echo $plain_password;
?>

任何人都知道如何在C＃中获得相同的结果？

我在C＃中的代码，我希望生成与PHP相同的代码。

输入：1234
