🔐 Password Manager (Java)
A secure, Java-based Password Manager that uses AES encryption, SHA-256 master authentication, and persistent encrypted storage to safely manage user credentials across sessions.
📌 Problem Statement
With the growing number of digital services, users are required to maintain multiple accounts with strong and unique passwords. This often leads to insecure practices such as password reuse or storing credentials in plain text, increasing the risk of data breaches and cyberattacks.
Existing password storage solutions either lack proper encryption or rely on insecure local storage mechanisms. There is a clear need for a secure, user-friendly, and persistent password management system that protects sensitive credentials without compromising usability.
🎯 Objective
To design and develop a secure Password Manager in Java that enables users to store, retrieve, and manage passwords safely using:
AES encryption for protecting stored passwords
SHA-256 hashing for master password authentication
Persistent local storage to retain encrypted data across sessions
✨ Key Features
🔐 AES Encryption & Decryption All stored passwords are encrypted using the Advanced Encryption Standard (AES) and decrypted only when required.
🔑 Master Password Authentication Vault access is protected using a master password verified via SHA-256 hashing.
💾 Persistent Encrypted Storage Encrypted credentials are stored securely in a local file or lightweight database (e.g., SQLite).
🔄 CRUD Operations Users can Add, View, Update, and Delete stored credentials.
🎲 Secure Password Generator Generates strong, random, and unpredictable passwords.
🖥 JavaFX GUI Interface A clean and intuitive graphical user interface for improved usability.
📝 Activity Logging (Optional) Logs important actions such as password creation or deletion for tracking and debugging.
🛠️ Technologies Used
Java
JavaFX (GUI)
AES (Advanced Encryption Standard)
SHA-256 Hashing
File System / SQLite (Persistent Storage)
🧩 System Workflow
User authenticates using a master password
Master password is verified using SHA-256 hashing
Passwords are encrypted using AES before storage
Encrypted data is stored persistently
Decryption occurs only during authorized retrieval
📊 Outcome
The project delivers a robust and secure password management solution that:
Protects sensitive credentials using industry-standard cryptography
Ensures secure and persistent local storage
Provides full credential management through CRUD operations
Enhances usability through a modern GUI
This project demonstrates practical knowledge of cryptography, authentication, secure storage, and GUI-based application development, aligning strongly with cybersecurity and software engineering principles.
🚀 Future Enhancements
Cloud-based encrypted synchronization
Auto-lock and inactivity timeout
Two-factor authentication (2FA)
Export / import encrypted vaults
Sensitive files, SDKs, and binaries are intentionally excluded from the repository using .gitignore. Users must install required dependencies separately.
