The Encryptor

Introduction

Welcome to The Encryptor! This application is a simple, yet powerful tool that leverages the OpenSSL library to provide secure encryption and decryption services. It's designed to be cross-platform, running on Mac, Windows, and Linux. Written in C++, it incorporates best coding practices, ensuring its maintainability and scalability.

Features

Encrypt or decrypt files in your local directory using AES (Advanced Encryption Standard) algorithm.
Generate random files for encryption/decryption testing.
Exception handling with custom OpenSSLException.
Interactive menu for ease of operation.

Installation

Prerequisites

Ensure you have installed the following dependencies on your system:

C++ compiler (with C++20 support)
CMake (minimum version 3.25)
OpenSSL library

Building the project

Clone this repository to your local machine.

git clone https://github.com/ricardoprins/encryption-sandbox.git

Navigate into the project directory.
```
cd encryption-sandbox
```
Create a new directory for the build, and navigate into it.
```
mkdir build && cd build
```
Configure the project with CMake.
```
cmake ..
```
Build the project.
```
cmake --build .
```

Docker-based Setup

If you have Docker installed on your machine, you can build and run the program without needing to manually install any of the prerequisites.

Clone this repository to your local machine.

git clone https://github.com/ricardoprins/encryption-sandbox.git

Navigate into the project directory.
```
cd encryption-sandbox
```
Build the Docker image.
```
docker build -t theencryptor .
```
Run the Docker image.
```
docker run -it theencryptor
```

Usage

After successful compilation, you can run the program by executing the created binary.

./theencryptor

The program will present an interactive menu allowing you to choose from encrypting a file, decrypting a file, viewing the contents of a file, and generating random test files.

For the Docker setup, the Docker container starts the program automatically when it runs.
