是否可以在 .NET 中 运行 一个 PHP 函数?
Is it possible to run a PHP function in .NET?
我正在尝试在 C# 中解密 AES-128 CBC 字符串,但没有成功(尝试了我在互联网上找到的每种加密类型的解密方法)。
我得到结果的唯一方法是使用以下代码解密 PHP 中的那些字符串:
<?php
$crypto_data = hex2bin($crypto_data_hex);
$real_data = openssl_decrypt($crypto_data,
'AES-128-CBC',
'23d854ce7364b4f7',
OPENSSL_RAW_DATA,
'23d854ce7364b4f7');
?>
那么,有没有办法在 .NET 中 运行 这个 PHP 代码(使用 PHP.dll 库或类似的东西)?或者在 .NET C# 中是否有用于此操作的 real 等效方法?
谢谢
问题似乎归结为编写等同于 PHP 函数的 C# 函数。
试试这个代码:
public class Program
{
public static byte[] HexToBytes(string hex)
{
int numberChars = hex.Length;
byte[] bytes = new byte[numberChars / 2];
for (int i = 0; i < numberChars; i += 2)
{
bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16);
}
return bytes;
}
static string Decrypt(byte[] cipherText, byte[] key, byte[] iv)
{
string plaintext;
AesManaged aes = new AesManaged
{
Mode = CipherMode.CBC,
Padding = PaddingMode.PKCS7,
BlockSize = 128,
Key = key,
IV = iv
};
using (aes)
{
ICryptoTransform decryptor = aes.CreateDecryptor();
using (MemoryStream ms = new MemoryStream(cipherText))
{
using (CryptoStream cs = new CryptoStream(ms, decryptor, CryptoStreamMode.Read))
{
using (StreamReader reader = new StreamReader(cs))
{
plaintext = reader.ReadToEnd();
}
}
}
}
return plaintext;
}
public static void Main()
{
string crypto_data_hex = "00965fa56e761b11d37b887f98e6bcc2"; // paste $crypto_data_hex value here
string sKey = "23d854ce7364b4f7";
string sIv = "23d854ce7364b4f7";
byte[] encrypted = HexToBytes(crypto_data_hex);
byte[] key = Encoding.ASCII.GetBytes(sKey);
byte[] iv = Encoding.ASCII.GetBytes(sIv);
string decrypted = Decrypt(encrypted, key, iv);
Console.WriteLine(decrypted);
}
}
