Security Best Practices

Follow these guidelines to ensure maximum security

API Key Management

Secure your API keys and rotate them regularly

javascript

// Store API keys securely
const API_KEY = process.env.ZKAUTH_API_KEY;

// Rotate keys regularly
// Set up automated key rotation every 90 days

HTTPS Only

Always use HTTPS in production environments

javascript

// Force HTTPS in production
if (process.env.NODE_ENV === 'production') {
  app.use((req, res, next) => {
    if (!req.secure) {
      return res.redirect('https://' + req.headers.host + req.url);
    }
    next();
  });
}

Rate Limiting

Implement rate limiting to prevent abuse

javascript

// Implement rate limiting
const rateLimit = require('express-rate-limit');

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

app.use('/api/', limiter);

Input Validation

Validate all user inputs to prevent injection attacks

javascript

// Validate email format
const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
if (!emailRegex.test(email)) {
  throw new Error('Invalid email format');
}

// Validate password strength
if (password.length < 8) {
  throw new Error('Password must be at least 8 characters');
}

Compliance Standards

ZKAuth meets the highest security and privacy standards

SOC2 Type II

Service Organization Control 2 compliance for security, availability, and confidentiality

HIPAA

Health Insurance Portability and Accountability Act compliance for healthcare data

GDPR

General Data Protection Regulation compliance for EU data protection

Troubleshooting Guide

Common issues, solutions, and debugging tools to help you resolve problems quickly

Authentication Failed

User authentication is not working

High

Solutions

Check API key configuration

Verify endpoint URLs

Ensure HTTPS in production

Check rate limiting

Code Example

javascript

// Verify API key format
const apiKey = 'zka_live_your_api_key_here';
if (!apiKey.startsWith('zka_live_')) {
  console.error('Invalid API key format');
}

Slow Response Times

API requests are taking too long

Medium

Solutions

Check network connectivity

Verify server resources

Optimize database queries

Enable caching

Code Example

javascript

// Add timeout configuration
const zkauth = new ZKAuth({
  apiKey: 'your_api_key',
  timeout: 10000, // 10 seconds
  retries: 3
});

Database Connection Issues

Cannot connect to database

High

Solutions

Check database credentials

Verify connection string

Ensure database is running

Check firewall settings

Code Example

javascript

// Test database connection
const { Pool } = require('pg');
const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
  ssl: process.env.NODE_ENV === 'production'
});

pool.query('SELECT NOW()', (err, res) => {
  if (err) {
    console.error('Database connection failed:', err);
  } else {
    console.log('Database connected successfully');
  }
});

ZK Proof Generation Failed

Zero-knowledge proof generation is failing

High

Solutions

Check circuit files

Verify cryptographic keys

Ensure sufficient memory

Update ZK libraries

Code Example

javascript

// Verify ZK proof generation
try {
  const proof = await zkauth.generateProof(credentials);
  console.log('Proof generated successfully');
} catch (error) {
  console.error('Proof generation failed:', error);
  // Check error details for specific issues
}

Debugging Tools

Useful commands and tools for debugging

Health Check

Check if ZKAuth service is running

Command

bash

curl -X GET https://api.zkauth.com/health

Expected Output

json

{
  "status": "healthy",
  "timestamp": "2024-01-01T00:00:00Z",
  "version": "1.2.0"
}

API Key Validation

Verify your API key is valid

Command

bash

curl -H "Authorization: Bearer zka_live_your_key" \
  https://api.zkauth.com/api/v1/auth/verify

Expected Output

json

{
  "valid": true,
  "permissions": ["read", "write"],
  "expires_at": "2024-12-31T23:59:59Z"
}

Database Status

Check database connectivity

Command

bash

curl -X GET https://api.zkauth.com/health/db

Expected Output

json

{
  "database": "connected",
  "response_time": "15ms",
  "active_connections": 5
}
