GeNieNigMa

A Python secure password generator that creates unique passwords of length 12, 16, or 20, always including lowercase, uppercase, digits, and special characters, with non-repeating sequences until all combinations are exhausted.

GeNieNigMa

A secure password generator built in Python that creates cryptographically strong passwords with guaranteed character diversity.

Features

• Cryptographically Secure: Uses Python's secrets module for true randomness
• Character Diversity: Every password contains at least one lowercase, uppercase, digit, and special character
• Multiple Lengths: Supports 12, 16, and 20 character passwords
• Duplicate Prevention: Tracks generated passwords to avoid repeats
• Simple CLI Interface: Easy-to-use command line interface

Installation

1. Clone this repository:

git clone <your-repo-url>
cd genienigma

2. No additional dependencies required - uses only Python standard library

Usage

Run the password generator:

python genienigma.py

Follow the prompts to select your desired password length (12, 16, or 20 characters).

Example Output

Secure Password Generator
Available lengths: 12, 16, 20
Enter password length (or 0 to quit): 16
Generated Password: K7$mP9qX&nE2vL4z

Character Sets

• Lowercase: a-z (26 characters)
• Uppercase: A-Z (26 characters)
• Digits: 0-9 (10 characters)
• Special: !@#$%^&*()_+-=[]{}|;:,.<>? (23 characters)

Total character pool: 85 characters

Security Features

Cryptographic Randomness

Uses secrets.choice() and secrets.SystemRandom().shuffle() for cryptographically secure random number generation, suitable for security-sensitive applications.

Guaranteed Complexity

Each password is guaranteed to contain:

• At least 1 lowercase letter
• At least 1 uppercase letter
• At least 1 digit
• At least 1 special character

Duplicate Prevention

The generator tracks all previously generated passwords and ensures no duplicates are returned until all possible combinations are exhausted.

Code Structure

PasswordGenerator Class

• __init__(): Initializes character sets and tracking
• generate_password(length): Creates a new unique password
• calculate_max_combinations(length): Estimates total possible passwords

Main Function

Provides the command-line interface for user interaction.

Technical Details

Password Generation Algorithm:

1. Select one character from each required category
2. Fill remaining positions with random characters from all sets
3. Shuffle the entire password to randomize positions
4. Check uniqueness against previously generated passwords
5. Return the password if unique, otherwise retry

Supported Lengths: 12, 16, 20 characters Platform: Cross-platform (Windows, macOS, Linux) Python Version: 3.6+

Security Considerations

• Uses cryptographically secure random number generation
• No password storage or logging
• Passwords are only displayed once and not saved
• Memory is cleared when the program exits
