I am connecting to the Amazon Product Advertising API, and to sign my request I need to base64-encode the raw binary output of an HMAC-SHA256 hash.
In t
php code
echo base64_encode(hash_hmac('SHA1', 'shanghai', '0', true).'beijing');
php output
xvBv49PpaYvXAIfy3iOSDWNQj89iZWlqaW5n
node code
var crypto = require('crypto');
var buf1 = crypto.createHmac("sha1", "0").update("shanghai").digest();
var buf2 = Buffer.from('beijing');
console.log(Buffer.concat([buf1, buf2]).toString('base64'));
node output
xvBv49PpaYvXAIfy3iOSDWNQj89iZWlqaW5n
This is explained in their documentation. Try this:
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.js for this. If you didn't include this, CryptoJS.enc.Base64
will be undefined
and fallback to the default.
Working demo: http://jsfiddle.net/ak5Qm/
PHP:
base64_encode(hash_hmac('sha256', $value, $key, true));
Nodejs equivalent:
const crypto = require('crypto');
let token = crypto.createHmac("sha256", key).update(value).digest().toString('base64');
This worked for me :
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, :
$rawSignature = hash_hmac("sha1", $baseString, $signingKey, true);
$signature = base64_encode($rawSignature);
You can also use this npm package to do the same in Javascript.
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;
};
