从C#到PHP的函数

c#

我需要将这些用 C# 开发的加密系统转换为 PHP。这些是输入数据。客户 ID、转换为字符串的 JSON 对象和私钥。

codigoCliente: 1002

数据：{"codigoCliente":1002,"codigoArticulo":"30-07483","cantidad":1}

claveSecretaServicio：RFlTfDIwMjBXZWJQYWdlX0V4dGVybmF

我需要得到这个哈希结果：WGHGEY830J3WeadO1o4NGNLYZ9lY7xvquol5igE+hLU=

这是 C# 中的调用：GetHash(modelo.CodigoCliente.ToString(), JsonSerializer.Serialize(modelo), “WGHGEY830J3WeadO1o4NGNLYZ9lY7xvquol5igE+hLU=”);

转换为 PHP 的 C# 函数是这些。

public static string GetHash(string codigoCliente, string datos, string claveSecretaServicio)
{
    var claveSecretaBytes = System.Convert.FromBase64String(claveSecretaServicio);
    var claveOperacion = Encrypt3DES(codigoCliente, claveSecretaBytes);
    var firmaBytes = GetHMACSHA256(datos, claveOperacion);
    return System.Convert.ToBase64String(firmaBytes);
}

private static byte[] Encrypt3DES(string codigoCliente, byte[] key)
{
    var codigoClienteBytes = System.Text.Encoding.UTF8.GetBytes(codigoCliente);
    TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
    byte[] SALT = new byte[8] { 0, 0, 0, 0, 0, 0, 0, 0 };
    tdes.BlockSize = 64;
    tdes.KeySize = 192;
    tdes.Mode = CipherMode.CBC;
    tdes.Padding = PaddingMode.Zeros;
    tdes.IV = SALT;
    tdes.Key = key;
    var cTransform = tdes.CreateEncryptor();
    byte[] resultArray = cTransform.TransformFinalBlock(codigoClienteBytes, 0, codigoClienteBytes.Length);
    tdes.Clear();
    return resultArray;
}

private static byte[] GetHMACSHA256(string data, byte[] key)
{
    byte[] dataBytes = Encoding.UTF8.GetBytes(data);
    using (HMACSHA256 hmac = new HMACSHA256(key))
    {
        byte[] hashValue = hmac.ComputeHash(dataBytes, 0, dataBytes.Length);
        return hashValue;
    }
}

我不知道 C#，所以我不太了解将它们更改为 PHP 的函数的详细工作原理。

我试过这个，但我的 HASH 结果是不同的。

/********************
 *      3DES
 ********************/
function encrypt_3DES($message, $key)
{
    $method = 'des-ede3-cbc';
    if (strlen($message) % 8) {
        $message = str_pad($message, strlen($message) + 8 - strlen($message) % 8, "");
    }
    $iv = "";
    $encrypted = openssl_encrypt($message, $method, $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv); //Force zero padding.
    return base64_encode($encrypted);
}

/********************
 *      SHA 256
 ********************/
function mac256($ent, $key)
{
    $res = hash_hmac('sha256', $ent, $key, true); // TRUE (PHP 5 >= 5.1.2)
    return $res;
}

/********************
 *      BASE 64
 ********************/
function encodeBase64($data)
{
    $data = base64_encode($data);
    return $data;
}
function decodeBase64($data)
{
    $data = base64_decode($data);
    return $data;
}

/********************
 *      HASH
 ********************/
function createHash($codigoCliente, $data, $key)
{
    $key = decodeBase64($key);

    $keyOperacion = encrypt_3DES($codigoCliente, $key);

    $res = mac256($data, $keyOperacion);

    return encodeBase64($res);
} 

我得到了一个有效的 3DES PHP 函数（感谢 Michael Fehr）

function encrypt_3DES($message, $key)
{
    $method = 'des-ede3-cbc';
    if (strlen($message) % 8) {
        $message = str_pad($message, strlen($message) + 8 - strlen($message) % 8, "");
    }
    $iv = "";
    $encrypted = openssl_encrypt($message, $method, $key, OPENSSL_RAW_DATA | OPENSSL_ZERO_PADDING, $iv); //Force zero padding.
    return base64_encode($encrypted);
}

但我仍然需要另外两个来实现有效的 HASH。也许如果你读了这篇迈克尔·费尔。

你的函数是正确的，我得到了与 C# 相同的中间 3DES 值：PD8fSM4gz3s=

先感谢您。
