在Javascript中计算签名/哈希并且与C#具有相同的结果

Question

我在C#中有以下代码

var apiKey = "SBB3aWxsIG1ha2UgbXbcQVBJIHN|Y3VyZQ==";
var apiSecret = "QaTW3xlf1U5ljdlAJSdltzT71fFF+eZ=";

var key = Convert.FromBase64String(apiSecret);
var provider = new System.Security.Cryptography.HMACSHA256(key);

var hash = provider.ComputeHash(Encoding.UTF8.GetBytes(apiKey));
var signature = Convert.ToBase64String(hash);

我试图使用CryptJS库在Javascript中获得相同的结果,但从我可以告诉我不是将密钥和秘密转换为字节数组并且编码不正确.首先尝试看起来像:

var apiKey = "SBB3aWxsIG1ha2UgbXbcQVBJIHN|Y3VyZQ==";
var apiSecret = "QaTW3xlf1U5ljdlAJSdltzT71fFF+eZ=";
var hash = CryptoJS.HmacSHA256(apiKey, apiSecret);
var sig = hash.toString(CryptoJS.enc.Base64);

使用Javascript

var CryptoJS = require('crypto-js');

var apiKey = "SBB3aWxsIG1ha2UgbXbcQVBJIHN|Y3VyZQ==";
var apiSecret = "QaTW3xlf1U5ljdlAJSdltzT71fFF+eZ=";

// var key = Convert.FromBase64String(apiSecret);
var key = CryptoJS.enc.Base64.parse(apiSecret);
console.log('key:' + key);

// var prehash = Encoding.UTF8.GetBytes(apiKey);
var prehash = CryptoJS.enc.Utf8.parse(apiKey);
console.log('Pre-hash:' + prehash);

// var provider = new System.Security.Cryptography.HMACSHA256(key);
// var hash = provider.ComputeHash(prehash);
var hash = CryptoJS.HmacSHA256(prehash, key);
console.log('hash:' + hash);

//var signature = Convert.ToBase64String(hash);
var signature = hash.toString(CryptoJS.enc.Base64);
console.log('signature:' + signature);

Javascript输出

            var apiKey = "SBB3aWxsIG1ha2UgbXbcQVBJIHN|Y3VyZQ==";
            var apiSecret = "QaTW3xlf1U5ljdlAJSdltzT71fFF+eZ=";
            var key = Convert.FromBase64String(apiSecret);
            Console.Write("key:");
            prtByte(key);

            Console.Write("Pre-hash:");
            prtByte(Encoding.UTF8.GetBytes(apiKey));
            var provider = new System.Security.Cryptography.HMACSHA256(key);
            var hash = provider.ComputeHash(Encoding.UTF8.GetBytes(apiKey));
            Console.Write("hash:");
            prtByte(hash);

            var signature = Convert.ToBase64String(hash);
            Console.WriteLine("signature:" + signature);
        }
        public static void prtByte(byte[] b)
        {
            for (var i = 0; i < b.Length; i++)
            {
                Console.Write(b[i].ToString("x2"));
            }
            Console.WriteLine();
        }
    }
}

C#输出
