问题描述

限时删除!!

我得到了以下HMAC密钥(十六进制格式):

I got the following HMAC key (in hexadecimal format):

52320e181a481f5e19507a75b3cae4d74d5cfbc328f7f2b738e9fb06b2e05b55b632c1c3d331dcf3baacae8d3000594f839d770f2080910b52b7b8beb3458c08

52320e181a481f5e19507a75b3cae4d74d5cfbc328f7f2b738e9fb06b2e05b55b632c1c3d331dcf3baacae8d3000594f839d770f2080910b52b7b8beb3458c08

我需要对此字符串签名:

I need to sign this string:

1100002842850CHF91827364

1100002842850CHF91827364

结果应为以下形式(十六进制格式):

The result should be this (in hexadecimal format):

2ad2f79111afd818c1dc0916d824b0a1

2ad2f79111afd818c1dc0916d824b0a1

我有以下代码:

string key = "52320e181a481f5e19507a75b3cae4d74d5cfbc328f7f2b738e9fb06b2e05b55b632c1c3d331dcf3baacae8d3000594f839d770f2080910b52b7b8beb3458c08";
string payload = "1100002842850CHF91827364";

byte[] keyInBytes = Encoding.UTF8.GetBytes(key);
byte[] payloadInBytes = Encoding.UTF8.GetBytes(payload);

var md5 = new HMACMD5(keyInBytes);
byte[] hash = md5.ComputeHash(payloadInBytes);

var result = BitConverter.ToString(hash).Replace("-", string.Empty);

但是,我没有得到结果.我在做什么错了?

However, I am not getting the result. What am I doing wrong?

推荐答案

而不是这样做:

byte[] keyInBytes = Encoding.UTF8.GetBytes(key);

您需要将密钥从十六进制字符串转换为字节数组.在这里您可以找到示例:

you need to convert key from a hex string to array of bytes. Here you can find example:

如何您如何将字节数组转换为十六进制字符串,反之亦然?
