Introduction

Encryptify is a robust file encryption and decryption application designed to secure sensitive data. Leveraging C++’s capabilities, the application efficiently manages file operations with multithreading, ensuring that encryption and decryption processes are both secure and efficient. The application implements semaphores and locks to coordinate access to shared resources, preventing data corruption.

Features

• File Encryption/Decryption: Securely encrypts and decrypts files using strong algorithms.
• Multithreading Support: Handles multiple file operations simultaneously, optimizing performance.
• Synchronization Mechanisms: Implements semaphores and locks for safe access to shared resources.
• User-Friendly Command-Line Interface: Simple and intuitive command-line options for ease of use.
• Configurable Settings: Users can modify encryption parameters according to their requirements.

Technologies Used

• C++
• Multithreading
• Semaphores and Locks
• Command-Line Interface (CLI)
• Makefile for build automation

Getting Started

Prerequisites

• C++ Compiler (e.g., g++)
• CMake (for building)
• Basic knowledge of C++ and command-line operations

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/encryptify.git
   cd encryptify
   

2. Compile the application using the Makefile:

      make
   

Running the Application

1. To run the encryption application, use the following command:

     ./encryptify --encrypt <input_file> <output_file>
   

2. To decrypt a file, use:

    ./encryptify --encrypt <input_file> <output_file>
