System Requirements Document (SRD)

1. Introduction

This document outlines the system requirements for a password generator tool. The tool is designed to help users create secure and customizable passwords for various applications. It will provide functionality to generate passwords based on user-defined criteria and ensure security and usability.

2. System Overview

The password generator tool will be a web-based application accessible via browsers. It will allow users to generate passwords based on specific parameters such as length, inclusion of symbols, numbers, and more. The system will also include features to ensure the generated passwords are secure and meet industry standards. The password strength will be visually indicated using color coding.

3. Functional Requirements as Story Points

• As a User, I should be able to generate a password by clicking a button named "Generate Password."
• As a User, I should be able to select the length of the password using a length selector.
• As a User, I should be able to toggle the inclusion of symbols in the password.
• As a User, I should be able to toggle the inclusion of numbers in the password.
• As a User, I should be able to copy the generated password to the clipboard.
• As a User, I should be able to view the strength of the generated password visually using color coding.
• As an Admin, I should be able to configure default password generation settings for all users.
• As an Admin, I should be able to view analytics on password generation usage (e.g., number of passwords generated).
• As a Guest, I should be able to generate a password without saving it.

4. User Personas

• User: A registered individual who uses the tool to generate and save passwords securely.
• Admin: A system administrator who manages the tool's settings and monitors usage analytics.
• Guest: An unregistered individual who uses the tool to generate passwords without saving them.

5. Visuals Colors and Theme

The password generator tool will use a clean and modern design with the following color scheme:

• Primary Color: Blue (#007BFF) for buttons and highlights.
• Secondary Color: White (#FFFFFF) for backgrounds.
• Accent Color: Green (#28A745) for success messages and password strength indicators.
• Error Color: Red (#DC3545) for error messages.
• Neutral Color: Gray (#6C757D) for text and secondary elements.
• Password Strength Colors:
  • Strong Password: Green (#28A745) for visual indication of strength.

The theme will focus on simplicity, usability, and accessibility, ensuring that users can easily navigate the tool and understand its features.

6. Non-Functional Requirements

• The system should be responsive and work seamlessly across different devices (desktop, tablet, mobile).
• The tool should ensure high security standards, including encryption for saved passwords.
• The system should have a user-friendly interface with clear instructions and feedback.
• The tool should handle up to 10,000 concurrent users without performance degradation.
• The system should comply with GDPR and other relevant data protection regulations.
• The tool should have a 99.9% uptime guarantee.

7. Tech Stack

Frontend

• React for Web

Backend

• Python
• FastAPI

Database RDBMS

• MySQL or MariaDB, use Alembic for migrations

AI Models

• GPT 5.2 for user-friendly responses

AI Tools

• Langchain

Local Orchestration

• Docker
• docker-compose

Server-side Orchestration

• Kubernetes

8. Assumptions and Constraints

• The tool will primarily be web-based, with no immediate plans for a mobile application.
• Users will need an internet connection to access the tool.
• Passwords saved within the tool will be encrypted using industry-standard algorithms.
• The system will not store passwords for Guests.
• Admins will have access to analytics but not to individual user passwords for privacy reasons.
• The password generator will exclusively produce strong passwords, eliminating the need for weak or medium strength indicators.

9. Glossary

• Password Strength: A visual indication of password security using color coding (e.g., green for strong).
• Clipboard: A temporary storage area for data that the user copies or cuts.
• Encryption: The process of converting data into a secure format that cannot be easily accessed without proper authorization.
• GDPR: General Data Protection Regulation, a legal framework for data protection and privacy in the European Union.
• Concurrency: The ability of the system to handle multiple users simultaneously.

This document has been updated to reflect the user's request for a color-coded password strength indicator and the exclusive generation of strong passwords.
