Passliss is a modern and secure web application for generating, analyzing, and managing passwords. It provides a clean interface, AI-powered tools, encryption utilities, and full customization to help users stay safe online.

## Features

Passliss offers a wide range of security-focused features:

### Password Generator

![Password Generator](https://raw.githubusercontent.com/Leo-Corporation/Passliss/main/.github/images/1.png)

The Generate page offers complete flexibility for creating random passwords:

- Choose the exact length
- Include or exclude symbols, numbers, uppercase or lowercase characters
- Generate multiple passwords in one click
- Export results as a CSV for secure storage or transfer

It also includes a simplified mode for quick generation and an advanced mode for fine-tuning every detail.

Passliss also integrates OpenAI’s GPT-4o-mini to let you generate secure passwords from natural language prompts. Whether you want a password that's "12 characters, includes symbols and is easy to remember" or "a banking-grade passphrase," the AI adapts to your needs and delivers strong, context-aware results.

### Strength Analysis

Easily evaluate the security of any password. The Strength page provides:

- A real-time strength score
- Detailed suggestions for improvement
- Visual indicators and contextual tips This helps users better understand how to avoid weak or easily guessable passwords.

### Encryption & Decryption
