Secure File Transfer System

This repository contains server and client Python scripts for a secure file transfer system over a network using SSL/TLS encryption. The system allows users to perform various operations such as listing files, downloading, uploading, and deleting files securely between the server and client. Features

Secure Communication: Utilizes SSL/TLS encryption for secure communication between the server and client, ensuring data confidentiality and integrity.
Multiple Operations: Supports operations like listing available files, downloading files from the server, uploading files to the server, and deleting files from the server.
Error Handling: Implements error handling mechanisms to deal with various exceptions and provide informative error messages to the users.
User-Friendly Interface: Offers a simple command-line interface for users to interact with the system easily.

Prerequisites

Python 3.x
OpenSSL library
Certificates: Both server and client require valid SSL/TLS certificates for secure communication. Ensure that the certificates are generated and stored correctly.
use openssl to generate your certificates. 
Commands : 
    for generating private key :  openssl genrsa -out private.key 2048
    for generating certificate signing request(csr) file : openssl req -new -key private.key -out csr.pem
    for generating a self signed certificate : openssl x509 -req -days 365 -in csr.pem -signkey private.key -out certificate.crt
        remeber : 
            while exectuting the thrid command it asks you details where "common name" is the "host name in the programs"

Usage

Clone the repository to your local machine.
Configure the server and client scripts with appropriate settings such as server IP address, port number, file paths, and certificate files.
Run the server script on the designated server machine.
Run the client script on the client machine and follow the prompts to perform desired file transfer operations.
Ensure proper network connectivity between the server and client for successful communication.

Security Considerations

Certificate Management: Proper management of SSL/TLS certificates is crucial for secure communication. Ensure that certificates are generated, stored, and configured correctly on both the server and client sides.
Secure File Handling: Implement secure file handling practices to prevent unauthorized access or tampering of files during transfer.
