Snd: Secure File Transfer

Snd is a file transfer program built using Golang, leveraging TCP for reliable and efficient data transmission. This application allows users to send and receive files securely over a network.

Features

• Fast and reliable file transfer over TCP.
• Secure file transmission
• Simple command-line interface for ease of use.
• Lightweight and efficient, suitable for various use cases.

Installation

To get started with the Snd application, follow these steps:

1. Clone this repo

git clone https://github.com/yourusername/snd.git

2. Cd into the repo

cd snd

3. Manage Dependecies

go mod tidy

4. Configure Snd

./snd -cert="cert/certs" -addr="127.0.0.1:4040" -dir="User/username/Desktop"

Before you can start using Snd you need to setup some config variables.

• -cert: the directory you would like to save your TLS certificates and keys
• -addr: the address your server starts on
• -dir the directory to store received files

5. Build Snd

go build -o snd

Running the Server

./snd -s

The server will listen for incoming file transfer requests, on the configured port.

Sending a File

./snd -f="your_filepath" -to="127.0.0.1:4040"

Receiving a File

The server will automatically receive the file sent by the client and store it in the specified directory.

How It Works

• Server: Listens for incoming TCP connections and handles file reception.
• Client: Connects to the server and sends files over the established TCP connection.
