Prerequisites

1. Install Python 3.9 or later
2. Install required package(s) using the command pip install -r requirements.txt

To Run

Client

1. Open another new terminal window and change directory into src/client
2. Run the command python -m src/client/index.py to start the client. Note - the private key's passphrase is "pass"

Server

1. Open a new terminal window and change directory into the src/server
2. Run the command python -m src/server/index.py to start the server.

User Configuration

Client

1. Edit src/client/config.ini and change the username

Server

Keypairs

The keypair will be generated on the client via its GUI interface. The public key must be located on the server prior to connection, else the server will not be able to authenticate the client. There are several ways to transfer the keys

• Using a secure protocol, such as via SSH
• Physically, such as via USB
