Javascript: Equivalent of PHP's hash_hmac() with RAW BINARY output?
提问by Kevin Cooper
I am connecting to the Amazon Product Advertising API, and to sign my request I need to base64-encode the raw binaryoutput of an HMAC-SHA256 hash.
我正在连接到亚马逊产品广告 API，为了签署我的请求，我需要对HMAC-SHA256 哈希的原始二进制输出进行 base64 编码。
In the PHP documentation for hash_hmac, the fourth parameter bool $raw_outputcontrols whether the output is raw binary data (true) or lowercase hexits (false). My program works in PHP by simply setting that parameter to true.
在hash_hmac 的 PHP 文档中，第四个参数bool $raw_output控制输出是原始二进制数据 (true) 还是小写十六进制数据 (false)。我的程序只需将该参数设置为 true 即可在 PHP 中运行。
However, I am now trying to port this over to Javascript. I tried using the CryptoJS.HmacSHA256() function, but it seems to be returning the lowercase hexits. How can I convert this to binary?
但是，我现在正在尝试将其移植到 Javascript。我尝试使用 CryptoJS.HmacSHA256() 函数，但它似乎返回了小写的十六进制。如何将其转换为二进制？
I have tried the following according to the CryptoJS documentation, but both outputs are identical:
我根据 CryptoJS 文档尝试了以下操作，但两个输出是相同的：
var hash = CryptoJS.HmacSHA256("hello", "key");
console.log(hash.toString());
console.log(hash.toString(CryptoJS.enc.Base64));

This is explained in their documentation. Try this:
这在他们的文档中进行了解释。试试这个：
var hash = CryptoJS.HmacSHA256("Message", "Secret Passphrase");
var base64 = hash.toString(CryptoJS.enc.Base64);
You need to include http://crypto-js.googlecode.com/svn/tags/3.0.2/build/components/enc-base64-min.jsfor this. If you didn't include this, CryptoJS.enc.Base64will be undefinedand fallback to the default.
为此，您需要包含http://crypto-js.googlecode.com/svn/tags/3.0.2/build/components/enc-base64-min.js。如果你没有包括这个，CryptoJS.enc.Base64将是undefined并回退到默认值。

PHP:
PHP：
base64_encode(hash_hmac('sha256', $value, $key, true));
Nodejs equivalent:
Nodejs 等效项：
const crypto = require('crypto');
let token = crypto.createHmac("sha256", key).update(value).digest().toString('base64');

You can also use this npm package to do the same in Javascript.
你也可以使用这个 npm 包在 Javascript 中做同样的事情。
var jsSHA = require('jssha');
hmac_sha1(string, key){
let shaObj = new jsSHA("SHA-1", "TEXT");
shaObj.setHMACKey(key, "TEXT");
shaObj.update(string);
let hmac = shaObj.getHMAC("B64");
return hmac;
};

This worked for me :
这对我有用：
var CryptoJS = require("crypto-js");
const raw_signature = hmacSHA1(baseString, signingKey);
const signature = raw_signature.toString(CryptoJS.enc.Base64);
It's giving the exact same result as, in PHP, :
它给出的结果与在 PHP 中完全相同：
$rawSignature = hash_hmac("sha1", $baseString, $signingKey, true);
$signature = base64_encode($rawSignature);
