comment chiffrer en AES/ECB/128 messages .Net?

A pris les vecteurs à partir de ce site http://www.inconteam.com/software-development/41-encryption/55-aes-test-vectors#aes-ecb-128

En javascript (sjcl) ont le même résultat

var key = [0x2b7e1516,0x28aed2a6,0xabf71588,0x09cf4f3c];
var test  = [0x6bc1bee2,0x2e409f96,0xe93d7e11,0x7393172a];
aes = new sjcl.cipher.aes(key);
r = aes.encrypt(test);
console.log(r);

Mais je ne peut pas l'atteindre dans le C#

    [TestMethod]
public void EncryptIntsToInts()
{
Int32[] key = { unchecked((Int32)0x2b7e1516), 0x28aed2a6, unchecked((Int32)0xabf71588), 0x09cf4f3c };
Int32[] test = { 0x6bc1bee2,0x2e409f96,unchecked((Int32)0xe93d7e11),0x7393172a };
Int32[] answer = { 0x3ad77bb4, 0x0d7a3660, unchecked((Int32)0xa89ecaf3), 0x2466ef97 };
var r = AES.EncryptIntsToInts(test, key.ToByteArray());
Assert.IsTrue(r.SequenceEqual(answer));
}
static byte[] zeroIV = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
public static Int32[] EncryptIntsToInts(Int32[] input, byte[] key)
{
//Check arguments.
if (input == null || input.Length <= 0)
throw new ArgumentNullException("input");
if (key == null || key.Length <= 0)
throw new ArgumentNullException("key");
//Declare the RijndaelManaged object
//used to encrypt the data.
RijndaelManaged aesAlg = null;
byte[] bResult;
try
{
aesAlg = new RijndaelManaged
{
Key = key,
Mode = CipherMode.ECB,
Padding = PaddingMode.None,
KeySize = 128,
BlockSize = 128,
IV = zeroIV
};
ICryptoTransform encryptor = aesAlg.CreateEncryptor();
byte[] bInput = new byte[input.Length * sizeof(int)];
Buffer.BlockCopy(input, 0, bInput, 0, bInput.Length);
bResult = encryptor.TransformFinalBlock(bInput, 0, input.Length);
}
finally
{
if (aesAlg != null)
aesAlg.Clear();
}
int[] iResult = new int[bResult.Length / sizeof(int)];
Buffer.BlockCopy(bResult, 0, iResult, 0, bResult.Length);
return iResult;
}

Quel est mon erreur?

Pourquoi la BCE? C'est vraiment la faiblesse de la mode.

Sur la note de côté: C'est le plus simple C# de mise en œuvre de l'AES 128 bits de la BCE fondés sur Texas Instruments AES 128 C mise en œuvre: github.com/jawadkhan92/TI_AES_128_CSharp
