Vimvq1987答案的扩展:
return hashValue.ToString();无法产生您想要/需要的输出。 您必须将数组hashValue中的字节转换为其十六进制字符串表示形式。
可以像2983042691371631631618一样简单(打印大写字母A-F),或者如果您喜欢它则更复杂一些:
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 string Encode(string input, byte[] key)
{
HMACSHA1 myhmacsha1 = new HMACSHA1(key);
byte[] byteArray = Encoding.ASCII.GetBytes(input);
MemoryStream stream = new MemoryStream(byteArray);
return myhmacsha1.ComputeHash(stream).Aggregate("", (s, e) => s + String.Format("{0:x2}",e), s => s );
}
static void Main(string[] args)
{
byte[] key = Encoding.ASCII.GetBytes("abcdefghijklmnopqrstuvwxyz");
string input = "";
foreach (string s in new string[] { "Marry", " had", " a", " little", " lamb" })
{
input += s;
System.Console.WriteLine( Encode(input, key) );
}
return;
}
}
}
哪个打印
3545e064fb59bc4bfc02b6e1c3d4925c898aa504
3249f4c8468d4d67f465937da05b809eaff22fdb

54579b0146e2476595381d837ee38863be358213
我得到完全相同的结果
$secretKey = 'abcdefghijklmnopqrstuvwxyz';
$signatureString = '';
foreach( array('Marry',' had',' a',' little',' lamb') as $s ) {
$signatureString .= $s;
echo hash_hmac('sha1', $signatureString, $secretKey, false), "\n";
}
编辑:Dmitriy Nemykin建议以下编辑
public static string Encode(string input, byte[] key)
{
byte[] byteArray = Encoding.ASCII.GetBytes(input);
using(var myhmacsha1 = new HMACSHA1(key))
{
var hashArray = myhmacsha1.ComputeHash(byteArray);
return hashArray.Aggregate("", (s, e) => s + String.Format("{0:x2}",e), s => s );
}
}
被拒绝了。 但是正如James在对此答案的评论中所指出的那样,至少使用using语句是一个好主意。
