@kavach/sdk

The official unified SDK for integrating with the Kavach Ecosystem (Kavach ID and Kavach Shield Engine).

Overview

This SDK allows developers to drop Kavach's high-security identity and risk management features directly into their applications.

Features

• Biometric Step-Ups: Seamlessly prompt users for FaceID/TouchID when the Kavach Shield Engine (KSE) demands a step-up for high-risk actions.
• Device Fingerprinting: Generate and securely transmit device trust telemetry (jailbreak detection, OS version).
• SSL Pinning: Prevent Man-in-the-Middle (MitM) attacks.
• Session Management: Secure token rotation and automated retry mechanisms.

Installation

npm install @kavach/sdk

Usage Example (Node.js)

const kseMiddleware = require('@kavach/sdk/express');

app.post('/transfer', 
  kseMiddleware.enforce({ level: 3, action: 'wallet_transfer' }), 
  (req, res) => {
    // If we reach here, KSE has authorized the request.
    res.json({ success: true });
});
