CheckPass
CheckPass is a privacy-first web application that evaluates password strength in real time. Built on cryptographic entropy calculations and pattern-risk detection, it provides immediate feedback, AI security suggestions, and a strong password generator.

About the Brand
This project focuses on designing and implementing a real-time password strength analyzer web application called CheckPass. By integrating client-side processing, mathematical entropy calculation, and crack time estimation, the system provides secure password evaluation, vulnerability detection, and a strong password generator. The project was developed to strengthen password security awareness while addressing modern cybersecurity challenges posed by weak user authentication and potential future attack vectors.
Project Objective
The primary objective was to design a privacy-first web tool that improves password security evaluation, minimizes credential exposure, and educates users through entropy assessment and crack time calculations. The project also evaluates system architecture, user interface design, and testing in a browser-based environment.
