Password Generator & Strength Checker

A simple Python script that generates secure passwords and evaluates their strength.

Features

• Customizable Password Generation: Specify minimum length and character types
• Strength Analysis: Automatically checks password security level
• Color-coded Ratings: Visual feedback with green/yellow/red indicators
• Simple Interface: User-friendly command-line prompts

How It Works

Password Generation

• Combines letters (uppercase and lowercase)
• Optionally includes numbers and special characters
• Ensures all selected character types are included
• Continues generating until minimum length is met

Strength Scoring System

Passwords are rated out of 5 points:

Criteria	Points
Length ≥ 12 characters	2 points
Length ≥ 8 characters	1 point
Contains both upper & lowercase	1 point
Contains numbers	1 point
Contains special characters	1 point

Strength Ratings

• STRONG (5/5): Excellent security
• MEDIUM (3-4/5): Good, but could be improved
• WEAK (0-2/5): Needs enhancement

Usage

1. Run the script:

   python password_gen.py

2. Follow the prompts:

   Enter the minimum length: 12
   Do you want to have numbers (y/n)? y
   Do you want to have special characters (y/n)? y
   

3. View the results:

   Generated password: A9b$kL8@qR2!

   PASSWORD STRENGTH ANALYSIS:
   ------------------------------
   Strength: STRONG (5/5)
   

Requirements

• Python 3.6+
• No external dependencies (uses standard library only)

Code Structure

• generate_password(): Creates passwords based on user criteria
• check_password_strength(): Analyzes password security
• Main section: Handles user input and displays results

Example Output

Generated password: p7@Gm2#Kn9!
==================================================

PASSWORD STRENGTH ANALYSIS:
------------------------------
Strength: MEDIUM (4/5)

Security Notes

• Passwords are generated using Python's random module
• No passwords are stored or transmitted
• Generated passwords meet minimum security criteria
