Password Strength Checker

Abstract

1. Introduction

Generate secure passwords, check for exposed passwords, get visual feedback for password strength or get form validation with a minimum password strength required.

Check the strength of the password in a visual way, with an animation when the strength changes according to the settings given by the user. Use it also inside a Form to get form validation!

2. Objective

Generate secure passwords, check for exposed passwords, get visual feedback for password strength or get form validation with a minimum password strength required.

This project demonstrates how Dart, Flutter can be applied to a real-world Cybersecurity & Ethical Hacking problem.

3. Key Features / Modules

• Check for exposed common password using the commonDictionary, a map with 10,000 leaked passwords!
• Use the PasswordStrengthChecker to have a visual feedback.
• Use the PasswordStrengthFormChecker to have a built-in TextFormField inside the widget and get form validation using a minimumStrengthRequired.
• Use the PasswordGenerator class to generate a secure random password based on the input configurations (PasswordGeneratorConfiguration).
• Create your custom strength to create your own rules or use the PasswordStrength default enum (see Custom Strength).
