Password Manager Project

Overview

This Python script provides a basic password manager functionality with encryption and secure storage using the AES encryption algorithm. The project utilizes the Crypto library for cryptographic operations and interacts with a MySQL database to store ,update and delete encrypted passwords and related information.

Requirements

• Python 3.x
• MySQL database

Required Python libraries:

• Crypto
• mysql-connector
• secrets
• string
• getpass
• zlib

Installation

Install the required Python libraries using the following command:

pip install pycryptodome mysql-connector-python

MySQL Database Setup:

1. Create a MySQL database named "passwordmanager."
2. Set up two tables: iv_n_key and psswrd_manager. The SQL schema is provided in the database_schema.sql file.

Configure Database Connection:

Open the Jupyter Notebook (Password-Manager-Project.ipynb) and update the database connection details (host, user, password) in the mysql.connector.connect calls within the functions (fetch_key, save_to_database, get_password_from_database, update_password, delete_password).

Usage

Run the Jupyter Notebook (Password-Manager-Project.ipynb) in your Python environment:

Password-Manager-Project.ipynb

The notebook provides a command-line interface with options:

• Enter 1 to save a new password
• Enter 2 to generate a password
• Enter 3 to show saved passwords
• Enter 4 to update a password
• Enter 5 to delete a password
• Enter 0 to exit

Follow prompts to perform actions.

Functions

1. generate_password(): Generates a random password with a mix of lowercase letters, uppercase letters, digits, and special characters. The password length is randomly chosen between 8 and 14 characters.

2. save_to_database(website, username, password): Encrypts the password and stores it in the MySQL database along with the website and username. If the user's key is not already stored in the database, it generates a new key.

3. get_password_from_database(website, username): Retrieves and decrypts the password from the database based on the specified website and username.

4. update_password(website, username, new_password): Updates the password for a specific website and username in the database.

5. delete_password(website, username): Deletes the password entry for a specific website and username from the database.

6. user_interface(): Provides a simple command-line interface for the user to interact with the password manager. Allows the user to perform actions such as saving, generating, displaying, updating, and deleting passwords.

Security Considerations

• Passwords are encrypted using the AES encryption algorithm with CBC mode and PKCS7 padding.
• Key derivation is performed using PBKDF2 with a random salt.
• The script uses a MySQL database to store encrypted passwords and related information.

Note: Ensure that you have secured your MySQL database appropriately, including proper authentication and access controls.
