从该站点获取了矢量http://www.inconteam.com/software-development/41-encryption/55-aes-test-vectors#aes-ecb-128

在javascript(sjcl)中有相同的结果

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);

但是我无法在C#中达到

    [TestMethod]

        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 };

            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,

                             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;
    }

我怎么了

开始编辑

新代码按正确的字节顺序排列,但不起作用

解决方法:

您使用32位整数来定义密钥.将它们转换为字节时,将使用本机字节序,通常是小字节序.所以您的密钥是16157e2b a6 …而不是2b7e1516 28 ….

首先,我不会使用整数来表示键.但是,如果您真的想编写一个大字节序转换函数.

我也强烈建议不要使用ECB模式.您可以将CBC与HMAC一起使用(先加密再进行mac构造),也可以使用第三方lib来实现GCM.
