Summary of Work

Password Hashing Utility Implementation

Overview

This pull request implements secure password hashing and comparison utility functions using bcrypt, providing robust password management capabilities for user authentication.

Key Changes

• Added hashPassword() function for secure password hashing
• Added comparePassword() function for password verification
• Implemented comprehensive input validation
• Used bcrypt with 12 salt rounds for secure hashing

Implementation Details

• Utilizes bcrypt library for industry-standard password hashing
• Prevents hashing of empty or short passwords
• Generates unique hashes for the same password
• Provides secure password comparison method

Security Considerations

• Uses 12 salt rounds for strong password hashing
• Validates password length before hashing
• Throws descriptive errors for invalid inputs
• Prevents potential timing attacks through bcrypt's compare method

Testing

• 100% test coverage for password utility functions
• Verified password hashing and comparison scenarios
• Tested edge cases like empty/short passwords
• Confirmed unique hash generation
• Validated successful and failed password comparisons

Notes

• Requires bcrypt dependency
• Configurable salt rounds for future adjustment
• Recommended for use in user registration and authentication flows

Changes Made

• Implemented hashPassword() function
• Implemented comparePassword() function
• Added input validation for password hashing
• Used bcrypt for secure password management

Tests

• Verify password hashing generates valid hash
• Confirm unique hash generation
• Test password comparison
• Validate input validation
• Check error handling for invalid passwords
