File-Security-Software

This repository contains a Python-based file security software that provides encryption and decryption functionalities using multiple algorithms, such as AES, RSA, and basic encryption methods. It allows users to securely encrypt files and then decrypt them using the corresponding keys.

Overview

The software is designed to handle various encryption and decryption operations on files, providing flexibility in choosing the encryption method based on the level of security required. The repository contains several example files demonstrating the encryption and decryption processes using different algorithms.

Features

• AES Encryption/Decryption: Secure file encryption using the AES (Advanced Encryption Standard) algorithm.
• RSA Encryption/Decryption: Public-key encryption and decryption using the RSA algorithm.
• Basic Encryption/Decryption: Simple encryption method for lower-level security requirements.
• Private/Public Key Management: Handling private and public keys for RSA encryption.

Setup Instructions

Prerequisites

• Python 3.x
• Required Python libraries (e.g., cryptography)

Installation

1. Clone the repository:

   git clone https://github.com/Abdulbasit110/File-Security-software.git
   cd File-Security-software

2. Install the required dependencies:

   pip install -r requirements.txt

Usage

1. To encrypt a file using AES:

   python original_code_file.py --encrypt --method aes --input your_file.txt

2. To decrypt a file encrypted with AES:

   python original_code_file.py --decrypt --method aes --input encrypted_aes_FE.txt

3. Similarly, you can use the RSA and basic methods by replacing --method aes with --method rsa or --method basic.
