HMAC Secured SaaS Feedback & Anti-Spoofing Voting
Defend your public roadmap and feature upvotes. Anonymous portals are easily spammed by competitor scripts or bots. NanoLog leverages backend-signed **HMAC SHA-256 signatures** to cryptographically verify client user payloads.
How HMAC Security Works
In standard SaaS setups, a client widget initializes with basic JSON variables, like `email: "user@domain.com"`. However, a malicious actor can open their console and execute init commands using another customer's email to access their private changelogs or vote on their behalf.
With NanoLog, your server signs the user context (e.g. `userId + email`) using a secret key provided in your project dashboard. Our API compares the signature, ensuring that the identity is authentic and has not been tampered with.
const crypto = require('crypto');
// 1. Define user attributes
const user = {
id: 'usr_98237',
email: 'customer@saas.com',
plan: 'pro'
};
// 2. Concatenate attributes to sign
const payload = `${user.id}:${user.email}:${user.plan}`;
// 3. Generate SHA-256 signature using your Project Secret Key
const secretKey = process.env.NANOLOG_SECRET_KEY;
const signature = crypto
.createHmac('sha256', secretKey)
.update(payload)
.digest('hex');
// 4. Pass context and signature securely to the client script
/*
window.NanoLog.init({
appId: 'YOUR_APP_ID',
context: user,
signature: signature
});
