Java Password Analyzer

A Java-based cybersecurity project designed to validate password strength, detect common weaknesses, and generate secure password suggestions.

Project Overview

The application evaluates user-entered passwords based on predefined security requirements and identifies weak or predictable patterns.

Key Features

• Validates password length (8–12 characters).
• Checks for uppercase and lowercase letters, numbers, and special characters.
• Detects passwords containing the user's email username.
• Identifies predefined weak words and sequential patterns.
• Detects four or more identical consecutive characters.
• Generates secure password suggestions using Java SecureRandom.

Implementation

The project is developed in Java using NetBeans and consists of four main components:

• Main: Handles user input and displays validation results.
• PasswordValidator: Checks password structure and email similarity.
• PasswordWeaknessChecker: Detects common weak words and predictable patterns.
• PasswordSuggestion: Generates alternative passwords that satisfy the implemented requirements.
