C#实现php的hash_hmac函数

from:http://blog.csdn.net/ciaos/article/details/12618487

 

PHP代码示例如下

 <?php

        $res1 = hash_hmac("sha1","signatureString", "secret");

        echo $res1."\n";

        //ee1b654aa861c41fd5813dc365ef106c9801f8f6

        echo base64_encode($res1)."\n";

        //ZWUxYjY1NGFhODYxYzQxZmQ1ODEzZGMzNjVlZjEwNmM5ODAxZjhmNg==



        $res2 = hash_hmac("sha1","signatureString", "secret", true);

        //echo "$res2\n";//binary byte[]

        $data = unpack('C*', $res2);

        print_r($data);

        /*

        Array

        (

            [1] => 238

            [2] => 27
