将 Javascript HMAC 转换为 C#

Question

hmac = CryptoJS.algo.HMAC.create(CryptoJS.algo.SHA256, secret_buffer);
    hmac.update(path, secret_buffer);
    var Sign= hmac.finalize();
    var signature = base64_encode(Sign);

已经用 C# 尝试过，但无法得到相同的答案

var key1 = sha1.ComputeHash(Encoding.UTF8.GetBytes("Test"));
        var key2 = key1.Concat(Encoding.UTF8.GetBytes("Test"));
        var key3 = sha1.ComputeHash(key2);
        var hmac=  Convert.ToBase64String(key3);

请给出一些解决方案？

Answer 1

你的JS代码相当于下面的代码（假设你的base64_encode()方法实现正确）：

var secret_buffer = "secret";
var path = "text";  

signature = CryptoJS.HmacSHA256(path, secret_buffer).toString(CryptoJS.enc.Base64);
console.log(signature);

在 С# 中，等价物是：

string secret_buffer = "secret";
string path = "text";       

using (var hmacsha256 = new HMACSHA256(Encoding.UTF8.GetBytes(secret_buffer)))
{
    var hash = hmacsha256.ComputeHash(Encoding.UTF8.GetBytes(path));
    var signature = Convert.ToBase64String(hash);

    Console.WriteLine(signature);
}
