Password Manager Script

This script allows you to securely store, retrieve, list, and delete passwords using encryption.

Prerequisites

  • Python 3
  • pip3 for installing Python packages
  • cryptography library

Installation

  1. Download the Script: Save the password_manager.py script to your local machine.

  2. Install Python and Pip: Ensure Python 3 and pip3 are installed on your system.

  3. Install cryptography Library: Use pip to install the cryptography library:

    pip install cryptography

Configuration

To make it easier to use the password manager script, you can set up aliases and update your PATH. Follow these steps:

  1. Open your shell configuration file:

    • For zsh (default on macOS), open ~/.zshrc: 
      nano ~/.zshrc
    • For bash, open ~/.bashrc: 
      nano ~/.bashrc

  2. Add the following configurations: Copy and paste the following lines into your shell configuration file:

    # Pip config
export PATH=$PATH:/usr/local/bin
alias pip='pip3'
alias py='python3'

# Password manager
alias password_manager='python3 /Users/CHANGEME/password_manager.py'

  3. Save and close the file:

    • In 'nano, press 'CTRL + X', then 'Y', and 'Enter'.

  4. Reload the shell configuration:

    • For 'zsh':
    source ~/.zshrc
    • For 'bash':
    source ~/.bashrc

Usage

  1. Generate and Store a Password 
    py password_manager generate "Password Title" "YourPassword"
  2. Retrieve a Stored Passoword 
    py password_manager retrieve "Password Title"
  3. List All Stored Passwords 
    py password_manager list
  4. Delete a Stored Password 
    py password_manager delete "Password Title"

Example Commands

  • To generate and store a password: 
    py password_manager generate "Email Password" "mypassword123"
  • To list all stored passwords: 
    py password_manager retrieve "Email Password"
  • To list all stored passwords: 
    py password_manager list

Notes

  • The script uses a master password to encrypt and decrypt the stored passwords.

  • Ensure you remember your master password, as you will need it to retrieve or delete stored passwords.

  • The passwords are stored in a JSON file named passwords.json in the same directory as the gitscript.
