PHP和C#3DES加密 [英] PHP and C# 3DES Encryption
问题描述
需要下面的函数从PHP转换为C#(asp.net)
Need to convert the following function from PHP to C# (asp.net)
function encrypt_3DES($message, $key){
// Se establece un IV por defecto
$bytes = array(0,0,0,0,0,0,0,0); //byte [] IV = {0, 0, 0, 0, 0, 0, 0, 0}
$iv = implode(array_map("chr", $bytes)); //PHP 4 >= 4.0.2
// Se cifra
$ciphertext = mcrypt_encrypt(MCRYPT_3DES, $key, $message, MCRYPT_MODE_CBC, $iv); //PHP 4 >= 4.0.2
return $ciphertext;
}
在哪里 $消息
是一个字符串连接code和 $键
是关键
Where
$message
is a string to encode and $key
is the key
的 $键
是基地64 EN codeD,这是德codeD调用函数之前
The $key
is base 64 encoded and it is decoded before calling the function
$key = $this->decodeBase64($key);
$ciphertext = $this->encrypt_3DES($message, $key);
下面的C#code我用:
Following C# code I used:
key = Base64Decode(key);
ciphertext = encrypt_3DES(order, key,true);
其中,
private string Base64Decode(string base64EncodedData)
{
byte[] base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
return Encoding.GetEncoding(28591).GetString(base64EncodedBytes);
// 28591 for php compatibility
}
和
private string encrypt_3DES(string message, string k,bool useHashing)
{
byte[] keyArray;
byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(message);
//If hashing use get hashcode regards to your key
if (useHashing)
{
MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
keyArray = hashmd5.ComputeHash(Encoding.GetEncoding(28591).GetBytes(k));
//Always release the resources and flush data
// of the Cryptographic service provide. Best Practice
hashmd5.Clear();
}
else
keyArray = UTF8Encoding.GetEncoding(28591).GetBytes(k);
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
//set the secret key for the tripleDES algorithm
tdes.Key = keyArray;
//mode of operation. there are other 4 modes.
//We choose ECB(Electronic code Book)
tdes.Mode = CipherMode.ECB;
//padding mode(if any extra byte added)
tdes.Padding = PaddingMode.PKCS7;
ICryptoTransform cTransform = tdes.CreateEncryptor();
//transform the specified region of bytes array to resultArray
byte[] resultArray =
cTransform.TransformFinalBlock(toEncryptArray, 0,
toEncryptArray.Length);
//Release resources held by TripleDes Encryptor
tdes.Clear();
//Return the encrypted data into unreadable string format
return Convert.ToBase64String(resultArray, 0, resultArray.Length);
}
从PHP和C#的结果是不一样的。
The results from PHP and C# are not the same.
推荐答案
我发现了一个code,在这个西班牙网站对我的作品。

I found a code that works for me in this spanish web. http://www.resuelvetusproblemas.com/convertir-encriptacion-en-php-3des-en-c/
这是在C#中的作用将是一样的,你已经用PHP编写的
This is the function in C# would be the same as you've written in PHP
public static byte[] TripleDESEncrypt(string texto, byte[] key)
{
using (TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider())
{
byte[] iv_0 = { 0, 0, 0, 0, 0, 0, 0, 0 };
byte[] toEncryptArray = Encoding.ASCII.GetBytes(texto);
tdes.IV = iv_0;
//assign the secret key
tdes.Key = key;
tdes.Mode = CipherMode.CBC;
tdes.Padding = PaddingMode.Zeros;
ICryptoTransform cTransform = tdes.CreateEncryptor();
//transform the specified region of bytes array to resultArray
byte[] resultArray =
cTransform.TransformFinalBlock(toEncryptArray, 0,
toEncryptArray.Length);
//Clear to Best Practices
tdes.Clear();
return resultArray;
}
}
