我得到了以下 HMAC 密钥(十六进制格式):
52320e181a481f5e19507a75b3cae4d74d5cfbc328f7f2b738e9fb06b2e05b55b632c1c3d331dcf3baacae8d3000594f839d770f2080910b52b7b8beb3458c08
我需要签署这个字符串:
1100002842850CHF91827364
结果应该是这样的(十六进制格式):
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。我究竟做错了什么?
