Secure Password Manager

Overview

Welcome to the Secure Password Manager project! This Python-based application is designed to store and manage your passwords securely. Utilizing robust encryption and hashing mechanisms, this password manager ensures that your sensitive information is protected. Whether you're a seasoned developer or an employer looking to gauge my skills, this project demonstrates my expertise in Python, cybersecurity, and database management.

Features

• User Authentication: Create and manage multiple accounts with securely hashed master passwords using bcrypt.
• Password Encryption: Store passwords securely with encryption using the cryptography.fernet module.
• Password Management: Easily add, view, update, and delete stored passwords in a user-friendly interface.
• Data Protection: Each password is encrypted with a unique key derived from the master password and a randomly generated salt.
• Cross-Platform Compatibility: The application runs seamlessly on both Windows and Unix-based systems.

Technology Stack

• Python: Core programming language used to build the application.
• SQLite: Database management system to store user credentials and encrypted passwords.
• bcrypt: Used for securely hashing user passwords.
• Fernet Encryption (cryptography.fernet): Ensures that all stored passwords are encrypted and secure.
• Tabulate: Provides a neat and organized display of stored passwords.

How It Works

1. Database Setup:

   • The application connects to an SQLite database (password_manager.db), creating tables for users and passwords if they don't already exist.

2. User Authentication:

   • Users can create a new account or sign in to an existing one. Passwords are hashed using bcrypt for security.

3. Password Management:

   • Users can add, view, update, or delete passwords. Passwords are encrypted before being stored in the database, ensuring they are never saved in plain text.

4. Encryption/Decryption:

   • The master password is used to derive an encryption key, which is then used to encrypt and decrypt stored passwords using the Fernet encryption.

Getting Started

Prerequisites

• Python 3.x: Ensure Python is installed on your system.

• Required Libraries: Install dependencies using pip:

  pip install bcrypt cryptography tabulate

Running the Application

1. Clone the Repository:

   git clone https://github.com/your-username/secure-password-manager.git
   cd secure-password-manager

2. Run the Application:

   python password_manager.py

3. Follow the On-Screen Prompts:

   • Create an account or log in to manage your passwords securely.

Future Improvements

• Two-Factor Authentication (2FA): Adding an extra layer of security during the login process.
• Password Strength Checker: Ensure that users create strong passwords.
• Backup and Restore: Allow users to back up their encrypted passwords and restore them when needed.
