NovaCrypt System

NovaCrypt is a simple cryptographic library for encryption and decryption of text data and files. It allows users to perform basic cryptographic operations using a custom key and salt.

Features

• Encryption and Decryption: Encrypt and decrypt strings and files.
• Customizable Parameters: Define a secure key and salt for cryptographic operations.
• File Operations: Encrypt and decrypt file contents.

Project Structure

• main.cpp: Contains the main program logic and user interface.
• novacrypt.cpp: Implements the NovaCrypt encryption and decryption algorithms.
• novacrypt.hpp: Header file for the NovaCrypt class.

Requirements

• C++11 or later
• CMake 3.10 or higher
• A C++ compiler (e.g., g++, clang++)

Installation

1. Clone the repository:

   git clone https://github.com/shovan04/NovaCrypt.git
   cd NovaCrypt

2. Create a build directory:

   mkdir build
   cd build

3. Run CMake to configure the project:

   cmake ..

4. Build the project:

   make

5. Run the executable:

   ./NovaCrypt

Usage

The NovaCrypt system provides a command-line interface to perform cryptographic operations. Upon running the executable, you will be prompted to choose a mode and enter the necessary parameters.

Modes

• Encryption: Encrypt text data.
• Decryption: Decrypt text data.
• Encrypt File: Encrypt the contents of a file and save the result to another file.
• Decrypt File: Decrypt the contents of a file and save the result to another file.

Example

Encrypt Text:

Enter SECURE_KEY(int): 12345
Enter SALT(int): 10
Enter MODE (1/2/31/32): 1
Enter the content: Hello, World!

Output:

Encrypted Data: [encrypted text]

Encrypt File:

Enter SECURE_KEY(int): 12345
Enter SALT(int): 10
Enter MODE (1/2/31/32): 31
Enter File Path for Encryption (Source): input.txt
Enter File Path for Decryption (Destination): encrypted_output.txt

Output:

Encrypted data saved to: encrypted_output.txt
