Bash Password Manager

This repository contains a simple password manager script written in Bash. The script provides a menu-driven interface to add, retrieve, and generate passwords for different accounts.

Features

• Add New Password: This feature allows you to add a new password for a specific account.

• Retrieve Password: This feature retrieves the password for a specified account.

• Generate Password: This feature generates a random password for a specified account.

• Generate Hash: This function generates a hash for the password of a specified account. It first clears the screen, then prompts the user to enter the account name. If the account exists in the password database, it generates a SHA256 hash of the password and displays it. If the account does not exist, it informs the user that the password was not found.

• Show Database: This function displays the entire password database. It first clears the screen, then reads and displays the contents of the password database file.

• Log In: This function handles user authentication. It prompts the user to enter a key. The entered key is hashed and compared with a pre-defined hashed key. If the keys match, the user is granted access and a welcome message is displayed. If the keys do not match, the user is prompted to enter the key again.

• Return to Main Menu: This function checks if the user input is “…”. If it is, the function returns to the main menu.
