Abstract

React Native Password Strength Checker is an open-source Cybersecurity & Ethical Hacking project. A react-native password input with strength checker for both IOS and Android. It is built using JavaScript. Key capabilities include: Use zxcvbn to check password strength, combine with custom rules and password length; Support for both IOS and Android, use ES6 React native; Animated strength bar. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

A react-native password input with strength checker for both IOS and Android

This Component is built using Dropbox zxcvbn password strength estimator library

2. Objective

A react-native password input with strength checker for both IOS and Android

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

3. Key Features / Modules

  • Use zxcvbn to check password strength, combine with custom rules and password length
  • Support for both IOS and Android, use ES6 React native
  • Animated strength bar
  • Check password is too short
  • Check password not match rules
  • Custom strength level (corresponding to 5 levels)
  • Custom style for password input and password strength

4. Technology Stack

JavaScript
