File Encryption Decryption Tool

Abstract

1. Introduction

This project is a simple file encryption and decryption tool developed in C++ that uses the AES encryption algorithm. The tool provides an easy way to secure sensitive data by allowing users to encrypt and decrypt files using a randomly generated encryption key. It demonstrates the basic process of reading, encrypting, and writing data to files, making it a great starting point for learning about file manipulation and encryption techniques.

2. Objective

Simple file encryption and decryption tool developed in C++

This project demonstrates how C++ can be applied to a real-world Cybersecurity & Ethical Hacking problem.

3. Key Features / Modules

• Generate a random encryption key for secure data protection.
• Encrypt files using the AES encryption algorithm to safeguard sensitive information.
• Decrypt previously encrypted files to restore original content.
• Basic command-line interface for user interaction.
• Educational and practical example for understanding encryption concepts and C++ programming.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/bogdanmoale/File-Encryption-Decryption-Tool.git
cd File-Encryption-Decryption-Tool

1. Clone the repository to your local machine.
