HMAC Hashing

Algorithm  SHA256

 

Please see the code examples below for an example on how to implement HMAC hashing.

 

Javascript Code Example

const crypto = require("crypto"); 
const secret = "advertiser-secret"; 
const orderId = "order-id123"; 
const algorithm = "sha256"; 
const hash = crypto.createHmac(algorithm,secret); hash.update(orderId); 
const signature = hash.digest('hex');

 

PHP Code Example

<?php 

// PHP Example 
// Documenation 
// https://www.php.net/manual/en/function.hash-hmac.php 

$secret = 'advertiser-secret'; 
$orderId = 'order-id123'; 
$algorithm = 'sha256'; 
$signature = hash_hmac($algorithm, $orderId, $secret);

 

Ruby Code Example

# !/usr/bin/env ruby 

# Documenation 
# https://ruby-doc.org/stdlib-2.4.0/libdoc/openssl/rdoc/OpenSSL/HMAC.html 

secret = "advertiser-secret" 
order_id = "order-id123" 
algorithm = "SHA256" 
signature = OpenSSL::HMAC.hexdigest(algorithm, secret, order_id)

Python Code Example

# Python HMAC Example 

# Documentation 
# https://docs.python.org/3/library/hmac.html 
# https://docs.python.org/3/library/hashlib.html 

import hmac 
import hashlib 
secret = "advertiser-secret" 
order_id = "order-id123" 
algorithm = hashlib.sha256 

# .encode converts the strings to bytes 
signature = hmac.new(secret.encode(), order_id.encode(), algorithm).hexdigest()
