Password Manager

This is a Python-based Password Manager application with a graphical user interface (GUI) built using Tkinter. The application allows users to securely store, retrieve, generate, and manage their passwords.

Features

• Secure Encryption: Passwords are encrypted using the Fernet symmetric encryption from the cryptography library.

• Password Management: Add, view, and delete passwords for different services.

• Password Validation: Ensure passwords meet strength requirements (length, uppercase, lowercase, special characters).

• Password Generation: Generate strong, random passwords of customizable length.

• Clipboard Copy: Copy usernames and passwords to the clipboard with a single click.

• Tab-Based Interface: Easy navigation between stored passwords and password generation.

Requirements

• Python 3.7+

• tkinter (pre-installed with Python)

• cryptography

Installation

1. Clone the repository:

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

cd password-manager

2. Install dependencies:

pip install cryptography

3. Run the application:

python password_manager.py

Usage

1. Adding a Password

• Navigate to the Passwords tab.

• Click on Add Password.

• Enter the service name, username, and password (or generate a strong password).

• Save the password. It will be securely encrypted and stored.
  
  

2. Viewing a Password

• Select a service from the password list.

• Click on View Password to see the username and password.

• Copy the username or password to the clipboard using the provided buttons.
  
  

3. Deleting a Password

• Select a service from the password list.

• Click on Delete Password to remove it.
  
  

4. Generating a Password

• Specify the desired length (minimum 8 characters).

• Click Generate to create a random password.

• Save the generated password to a service or copy it to the clipboard.
  
  

File Structure

password_manager.py: Main application file.

key.key: Automatically generated encryption key (stored securely).

passwords.enc: Encrypted file storing all passwords.

Security Notes

• The application uses Fernet encryption to securely encrypt and decrypt password data.

• The key.key file is required to access the encrypted passwords. Keep this file secure and do not share it.

• Always use strong master passwords and enable additional security measures if integrating with external systems.

Future Enhancements

• Implement a master password to further secure access to the application.

• Add support for exporting and importing password data.

• Integrate cloud backup for encrypted password storage.

• Provide more customization options for password generation.
