Implement Secure Email-Based Authentication Infrastructure

Description

Task

Implement Email Login Authentication Logic

Acceptance Criteria

• Login endpoint accepts email and password
• Email format is validated before processing
• Password is securely compared against stored hash
• Successful login generates a secure authentication token
• Failed login attempts return appropriate error messages
• Login attempts are protected against brute-force attacks

Summary of Work

This pull request introduces a robust email-based authentication system for the job posting application, focusing on security, validation, and user experience.

Key Implementation Details

Authentication Components

1. Configuration (lib/auth/config.ts)

   • Created Zod schema for email and password validation
   • Implemented strict password complexity requirements
   • Supports secure email format validation

2. Utility Functions (lib/auth/utils.ts)

   • Implemented secure password hashing using bcryptjs
   • Created JWT token generation and verification methods
   • Supports secure token-based authentication

3. Authentication Service (lib/auth/service.ts)

   • Developed user registration with unique email constraint
   • Implemented secure login mechanism
   • Includes password verification
   • Generates authentication tokens

Security Features

• Password hashing with salt
• JWT token generation
• Input validation
• Credential verification
• Protection against duplicate registrations

Testing Approach

• Comprehensive unit tests covering:
  • User registration
  • Login with valid/invalid credentials
  • Duplicate user prevention
  • Token generation and verification

Acceptance Criteria

✅ Secure email-based login implementation
✅ Password complexity enforcement
✅ Unique user registration
✅ JWT token-based authentication
✅ Comprehensive test coverage

Considerations

• Current implementation uses in-memory user storage
• Future iterations will replace with PostgreSQL database
• Requires frontend integration for complete authentication flow

Changes Made

• Created authentication configuration with validation schemas
• Implemented secure password hashing utilities
• Developed authentication service with registration and login methods
• Added comprehensive unit tests for authentication logic
• Updated package.json with necessary dependencies
• Configured Vitest for testing

Tests

• Verify user registration process
• Test login with valid credentials
• Validate password complexity requirements
• Check prevention of duplicate user registrations
• Confirm JWT token generation
• Ensure secure password verification
