I need to implement some crypto protocol on C# and want to say that this is my first project in C#. After spending some time to get used on C# I found out that I am unable to get compliant AES vectors.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
using System.IO;
namespace ConsoleApplication1
{
class Program
{
public static void Main()
{
try
{
//test vectors from "ecb_vk.txt"
byte[] key = { 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
byte[] data = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
byte[] encTest = { 0x0e, 0xdd, 0x33, 0xd3, 0xc6, 0x21, 0xe5, 0x46, 0x45, 0x5b, 0xd8, 0xba, 0x14, 0x18, 0xbe, 0xc8 };
AesManaged aesAlg = new AesManaged();
aesAlg.BlockSize = 128;
aesAlg.Key = key;
aesAlg.Mode = CipherMode.ECB;
ICryptoTransform encryptor = aesAlg.CreateEncryptor();
MemoryStream msEncrypt = new MemoryStream();
CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write);
StreamWriter swEncrypt = new StreamWriter(csEncrypt);
swEncrypt.Write(data);
swEncrypt.Close();
csEncrypt.Close();
msEncrypt.Close();
aesAlg.Clear();
byte[] encr;
encr = msEncrypt.ToArray();
string datastr = BitConverter.ToString(data);
string encrstr = BitConverter.ToString(encr);
string encTestStr = BitConverter.ToString(encTest);
Console.WriteLine("data: {0}", datastr);
Console.WriteLine("encr: {0}", encrstr);
Console.WriteLine("should: {0}", encTestStr);
Console.ReadKey();
}
catch (Exception e)
{
Console.WriteLine("Error: {0}", e.Message);
}
}
}
}
Output is wrong:
data: 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
encr: A0-3C-C2-22-A4-32-F7-C9-BA-36-AE-73-66-BD-BB-A3
should: 0E-DD-33-D3-C6-21-E5-46-45-5B-D8-BA-14-18-BE-C8
I am sure that there is correct AES implementation in C#, so I need some advice from C# wizard to help whit this.
Thanks
