Password Manager

A secure command-line password manager written in C using OpenSSL for encryption. This program allows users to store, retrieve, and manage their passwords securely, ensuring that sensitive information remains safe from unauthorized access.

Features

• Add New Services: Store service names, usernames, and passwords (randomly generated if not provided).
• Retrieve Credentials: Easily fetch stored credentials based on service names.
• List Services: View all stored services in the vault.
• Secure Encryption: Utilizes AES encryption with a derived key from a master password.
• Hidden Input: The master password is entered without displaying it on the screen.
• Command-Line Interface: User-friendly command-line options for managing passwords.

Requirements

• OpenSSL Development Libraries
• A C compiler (e.g., GCC)

Installation

1. Clone the repository:

   git clone https://git.bidonov.xyz/root/Password-Manager.git
   cd password-manager
   

2. Compile the program:

   gcc -o password_manager password_manager.c -lssl -lcrypto
   

3. Compile the program:

   gcc -o password_manager password_manager.c -lssl -lcrypto
   

Usage

Run the program with the following command:

./password_manager --help

This will display the available options and how to use the password manager.

Examples

• To add a new service with a randomly generated password:

./password_manager --add <service_name> --username <username>

• To retrieve credentials for a service:

./password_manager --get <service_name>

• To list all stored services:

./password_manager --list

Security Considerations

• The passwords are securely encrypted using AES-256-CBC.
• Keys are derived from a user-provided master password using PBKDF2 for added security.

Future Improvements

• Implementing multi-factor authentication.
• Enabling password sharing features.
• Developing a web-based interface for improved accessibility.
