🚀 Features

• 🔐 User Registration and Login

  • Master password is securely hashed using PBKDF2 with SHA-256.
  • Login protects access to the entire vault.

• ✍️ Save New Credentials

  • Store website name, username, and password.
  • Passwords are encrypted before saving.

• 👁️ View Password (with Master Password)

  • Re-authentication required before revealing stored passwords.

• ✏️ Edit and Delete Credentials (secure)

  • Both actions require entering the master password.

• 👁️‍🗨️ Toggle Password Visibility

  • Show/hide password while typing new credentials.

• 🎨 Modern Dark Theme GUI

  • Styled using the 'clam' theme for clean and sharp UI.
  • All widgets follow a black-grey-white color scheme.

📁 Project Structure

• gui.py – GUI layout and event handling using tkinter. Manages input fields, buttons, layout structure, and opens modal windows (e.g., for master password, edit, delete).
• app.py – Main launcher file that starts the application and integrates all modules.
• db.py – Handles all MySQL database operations:
  • Connecting to the database
  • Inserting, updating, deleting credentials and user data
• encryption.py – Handles all security-related logic:
  • Master password is hashed using PBKDF2 with SHA-256
  • Credential passwords are encrypted and decrypted using Fernet (symmetric encryption)
• db_setup.sql – SQL file to set up the MySQL database:
  • Creates tables like users, credentials, and security_questions
  • Defines relationships and constraints
• requirements.txt – Lists all the Python dependencies required to run the project:
  • tkinter
  • cryptography
  • mysql-connector-python
• README.md – You’re reading it! 😄 This file explains the project, features, setup instructions, and usage.

🧠 Security Implementation

• Master Password

  • Stored as a salted hash using PBKDF2-HMAC-SHA256 with a unique salt per user.

• Stored Credentials

  • Passwords encrypted using Fernet symmetric encryption (AES under the hood).
  • Keys securely derived and stored in MySQL.

📜 Setup Guide

1. Clone the Repository

git clone https://github.com/DevanshuHB cd password-vault

2. Set Up MySQL

• Make sure MySQL is installed and running.

• Run the provided SQL file:

SOURCE db_setup.sql;

3. Install Dependencies

Install the required Python libraries using:

pip install -r requirements.txt

Make sure you have Python 3.x installed. If pip doesn't work, try:

pip3 install -r requirements.txt

💡 This installs all required modules like tkinter, mysql-connector-python, etc.

4. Run the code

python gui.py

🔐 Folder Security Tip

• Never share your .env file or database credentials publicly.
• Avoid pushing pycache, .db files, or any sensitive tokens if added later.

🚀 Future Improvements

• 🔍 Add search functionality to find credentials quickly.
• ❓ Implement "Forgot Master Password" feature using security questions.
• 📦 Package the app as an executable for easier distribution.
• 🌙 Add dark/light theme toggle for user preference.
• 🔒 Improve encryption strategy with salting per credential.
