🔐 Password Manager

A simple command-line interface (CLI) Password Manager written in C++ that allows users to store, encrypt, and decrypt passwords securely. This project uses OpenSSL for encryption and decryption of passwords and a text file for storing the encrypted data.

✨ Features

• 🔒 Save Passwords: Save usernames and encrypted passwords to a file.
• 🔓 Load Passwords: Load and decrypt passwords from the file.
• 🔑 Encryption and Decryption: Uses AES-256-CBC encryption for secure password management.
• 💻 CLI Interface: Simple command-line interface for ease of use.

📋 Prerequisites

• C++11 or later
• OpenSSL library
