Security, QA & Best Practices Skill

Quick Start - Secure Authentication

import bcrypt from 'bcrypt';
import jwt from 'jsonwebtoken';

// Hash password
const password = 'user_password';
const hash = await bcrypt.hash(password, 10);

// Verify password
const isValid = await bcrypt.compare(password, hash);

// Issue JWT
const token = jwt.sign(
  { userId: 1, email: 'user@example.com' },
  process.env.JWT_SECRET,
  { expiresIn: '24h', algorithm: 'HS256' }
);

// Verify JWT
const decoded = jwt.verify(token, process.env.JWT_SECRET);
