🔐 DEEncrypt

---

🚀 Overview

DEEncrypt is a simple CLI tool that uses character shifting to encrypt and decrypt text. It is built with a focus on defensive programming, standard C I/O conventions, and clean memory management.

✨ Features

• Defensive Buffer Management: Prevents overflow using explicit error codes (SUCCESS, NULL_PTR, BUFFER_TOO_SMALL).
• Interactive CLI Menu: Easy-to-use console interface.
• Zero Dependencies: Pure C implementation using standard Windows API-like function signatures.

🛠️ Building & Running

Prerequisites

• GCC or any standard C compiler (e.g., MinGW for Windows).

gcc main.c -o DEEncrypt.exe

Usage

Run the compiled executable directly in your command prompt, or simply double-click the file on Windows:

Follow the on-screen menu to encrypt or decrypt your text messages.
