Password Strength Tester and Cracker

Project Overview

This project is a Password Strength Tester and Cracker developed using Java. It allows users to generate random passwords, check the strength of their passwords, and simulate password cracking using a brute-force approach.

Features

• User Input: Users can input their own passwords for analysis.
• Random Password Generation: Generate secure passwords of specified lengths.
• Strength Analysis: Evaluate password strength based on length and character variety.
• Cracking Simulation: Demonstrates the vulnerability of weak passwords to brute-force attacks.

Installation
