Computing Podpis/Hash w JavaScript i mieć taki sam wynik jak C#

Question

Mam następujący kod w C#

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); 

Próbuję uzyskać ten sam rezultat w JavaScript z wykorzystaniem biblioteki CryptJS ale z tego co mogę powiedzieć I nie konwertuję klucza i sekretu na tablice bajtów, a kodowanie jest niepoprawne. Pierwsza próba wygląda następująco:

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

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);
