Secure File Encryption Tool

A C project for developing a secure file encryption tool. This project demonstrates key concepts in C programming, including file handling, dynamic memory management, and secure encryption algorithms.

Features

• File Encryption/Decryption: Securely encrypt and decrypt files.
• Dynamic Memory Management: Efficiently handle file data using dynamic memory allocation.
• File Handling: Read and write encrypted data to and from files.
• Secure Algorithms: Implement encryption and decryption algorithms to protect file contents.

Getting Started

Prerequisites

• C Compiler (e.g., GCC)
• Basic knowledge of C programming, pointers, and memory management

Installation

1. Clone the repository: git clone https://github.com/onaisahmed/secure-file-encryption-tool.git

2. Navigate to the project directory: cd secure-file-encryption-tool

3. Compile the project: gcc -o encryption_tool main.c encryption.c decryption.c

Usage

1. Encrypt a File: ./encryption_tool encrypt input.txt output.enc

2. Decrypt a File: ./encryption_tool decrypt output.enc decrypted.txt
