Java C#指定密钥是'；三倍体'；不能使用

我有一个用Java编写的身份验证过程，它将一个字符串加密到MD5中并生成一个字符串，只取该字符串的前8位。 在本例中，生成的字符串是“89a5c474”。

之后，我有下面这段Java代码，其中我使用了TripleDesEncryption

public static byte[] encrypt(byte[] keybyte, byte[] src) throws NoSuchAlgorithmException, NoSuchPaddingException, Exception 
{ 
    System.out.println("Key Byte " + byte2hex(keybyte) + "Key Byte Array" + keybyte);
    System.out.println("Key String " + byte2hex(src));
    SecretKey deskey = new SecretKeySpec(keybyte, DESede); 
    Cipher c1 = Cipher.getInstance(Algorithm); 
    c1.init(Cipher.ENCRYPT_MODE, deskey); 
    return c1.doFinal(src);
} 

public static void main(String[] args) 
{
        final byte[] rawKey = "89a5c474".getBytes(); 
        final byte[] keyBytes = new byte[24]; 
        for (int i = 0; i <rawKey.length; i++) 
        { 
            keyBytes[i] = rawKey[i]; 
        }

        for (int i = rawKey.length; i <keyBytes.length; i++) 
        { 
            keyBytes[i] = (byte)0; 
        }


        String szSrc = "20126303$4A6D9BD0DDD094B76C111577A49EB87A$Guest$PC$193.92.123.5$$Reserved$CTC";         
        byte[] encoded = null;

        try 
        {            
            encoded = encrypt(keyBytes, szSrc.getBytes());          
        } 
        catch (Exception e) 
        { 
            e.printStackTrace(); 
        }                       
}

我认为您的密钥可能都是零，这是不允许的。不完全是，在密钥的24个字节中，我只占用了8个字节，而其余的都是0。但是，我不能更改密钥，因为身份验证接口使用的是相同的密钥，但在Java接口中

    public static string AuthenticatePassword(string token, string hashPassword)
    {
                byte[] rawKey = UTF8Encoding.UTF8.GetBytes(hashPassword);
                byte[] keyBytes = new byte[24];



                for (var i = 0; i < rawKey.Length; ++i)
                {
                    keyBytes[i] = rawKey[i];
                }

                for (int i = rawKey.Length; i < keyBytes.Length; i++)
                {
                    keyBytes[i] = 0;
                }

                string keyString = "20126303$" + token + "$Guest$PC$193.92.123.5$$Reserved$CTC";

                return Encrypt(keyBytes, System.Text.Encoding.ASCII.GetBytes(keyString), rawKey, keyString);
    }
public static string Encrypt(byte[] keyBytes, byte[] keyString)
{

            try
            {
            TripleDESCryptoServiceProvider des = new TripleDESCryptoServiceProvider();

            des.Key = keyBytes;
            des.Mode = CipherMode.ECB;
            des.Padding = PaddingMode.PKCS7;                
            ICryptoTransform ic = des.CreateEncryptor();
            byte[] enc = ic.TransformFinalBlock(keyString, 0, keyString.Length);
            }
            catch (Exception e)
            {
                Console.WriteLine("[Encryption Error] {0}", e.Message); 
            }
return string.Join(string.Empty, enc.Select(x => x.ToString("X2")));
}

        TripleDESCryptoServiceProvider sm = new TripleDESCryptoServiceProvider();
        MethodInfo mi = sm.GetType().GetMethod("_NewEncryptor", BindingFlags.NonPublic | BindingFlags.Instance);
        object[] Par = { EmptyKey, CipherMode.ECB, keyBytes, sm.FeedbackSize, 0 };
        ICryptoTransform trans = mi.Invoke(sm, Par) as ICryptoTransform;
        byte[] enc = trans.TransformFinalBlock(keyString, 0, keyString.Length);
