Question

为什么我的HMAC不同？
我在这里创建了一个visual studio 2012解决方案：https://github.com/tonyeung/hmacsha512

我的js

    <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>
    <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>

    var rawSig = "abc:123:Fri, 28 Jun 2013 15:03:00 GMT";
    var token = "c22b31a2-780b-4ac5-8bd5-1296b05130f4"
    var hash = CryptoJS.HmacSHA512(rawSig, token);
    var sig = hash.toString(CryptoJS.enc.Base64);

我的c＃

    public JsonResult hmac(string sig, string token)
    {
        var signature = string.Empty;
        using (var hmac = new HMACSHA512(Encoding.UTF8.GetBytes(token)))
        {
            var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(sig));
            signature = Convert.ToBase64String(hash);
        }

        return Json(signature);
    }

结果：

CryptoJS Result

我需要翻转cryptojs参考

这

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>

到

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/hmac-sha512.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/enc-base64-min.js"></script>

发现此网站非常有用：http://jokecamp.wordpress.com/2012/10/21/examples-of-creating-base64-hashes-using-hmac-sha256-in-different-languages/

将cryptojs与c＃hmacsha512匹配
