Password Strength Analyzer and Breach Checker is a cybersecurity-focused Java application designed to evaluate password security and identify passwords that appear in a breached password dataset.
The project demonstrates practical cybersecurity concepts including password security assessment, breach detection, secure database interaction, and user awareness mechanisms.
- Password Security Analysis
- Breached Password Detection
- Secure Database Queries using Prepared Statements
- Basic Security Risk Assessment
- Authentication Security Awareness
- Input Validation
- SQLite Database Security Integration
Evaluates password complexity based on:
- Password Length
- Uppercase Characters
- Lowercase Characters
- Numeric Characters
- Special Characters
Checks whether a password exists within a database of commonly breached passwords.
Provides suggestions to improve weak passwords and enhance account security.
Stores analysis results including:
- Password Strength
- Breach Status
- Analysis Records
Built using Java Swing with:
- Show/Hide Password Option
- Visual Strength Indicators
- Real-Time Feedback

The application evaluates passwords using a rule-based scoring model that considers:
- Length Requirements
- Character Diversity
- Complexity Metrics
Passwords are compared against a breached-password dataset stored in SQLite.
Prepared Statements are used for database queries to reduce SQL Injection risks.
Example:
PreparedStatement pstmt =
conn.prepareStatement(query);| Password | Strength | Breached |
|---|---|---|
| 123 | Weak | No |
| password | Weak | Yes |
| Admin123 | Medium | No |
| Admin@123 | Strong | No |
| 123456 | Weak | Yes |
- SHA-256 Password Hashing
- Password Entropy Calculation
- Integration with Have I Been Pwned API
- Real-Time Breach Intelligence
- Advanced Password Policy Engine
- Security Analytics Dashboard
