Password Strength Analyzer
An intelligent password security analysis tool developed for the Barclays Hackathon 2025, combining machine learning, security analysis, and GenAI-powered password improvement recommendations.
Project Overview
Password Strength Analyzer is a web-based security tool developed for the Barclays Hackathon 2025 to analyze password strength and provide intelligent recommendations for improving password security.
The application evaluates passwords using multiple security dimensions including entropy, character variety, common patterns, dictionary vulnerability, estimated crack time, and potential attack vectors. It also provides personalized password improvements designed to increase security while maintaining memorability.
Technical Challenges
One of the main challenges was combining traditional password security analysis with machine-learning-based strength prediction and intelligent recommendations.
The application analyzes password characteristics such as entropy, character composition, common patterns, dictionary vulnerabilities, and estimated crack time. It also identifies potential attack vectors including dictionary, brute-force, targeted-guessing, and hybrid attacks.
Another challenge was generating stronger passwords without making them difficult to remember. The enhancement engine applies targeted transformations such as character substitution, capitalization changes, special-character insertion, and security-level calibration.
The backend is implemented with Python and Flask, while the frontend uses JavaScript, HTML, Tailwind CSS, and asynchronous AJAX requests for interactive analysis.
