Installation

From source code

You need to have Python and PIP installed which you can download from your package manager or site.

After installing Python and PIP you need to install program dependencies. You can with this command:

git clone https://github.com/aniko33/Charles-CSEC && cd Charles-CSEC

Then, you will need to install python dependencies:

pip install -r requirements.txt

After you installed the various dependencies, now you can customise your configurations your server or start your client.

From the compiled version

You have to go to the latest releases and you have to download the client or the server depending on what you want to do.

Important note

If you have installed the server version, create a file named config.json and set the default configurations.

Configuration

To configure your server, open the config.json file in the following path: server/config.json.

Scroll to the top and edit this part:

{
    "ip": "127.0.0.1",
    "port": 8889,
    "buffer": 1024,
    "welcome_message": "[red]welcome to <chat name>[/red]",
    "protected_by_password": false,
    "password": "P4ssw0rd"
}

Variable	Description
ip	The IP address where the server will start listening for connections
port	The connection port, it is recommended to keep it default (8889)
buffer	The maximum network buffer, changes in this value affects the RSA key lenght
welcome_message	Welcome message to new users, the colors can be found in the Rich documentation
protected_by_password	You can enter true if you want to protect your chat by password or you can put false
password	Enter the password you want

Commands

• /help show command list

• /nick get your nickname

• /upload <path> upload file with Anonfile, usage: /upload /home/user/file.txt

Running

To run the program just go to the main folder and execute this command:

Client

cd client && python main.py

Server

cd server && python main.py

How does it work

The keys are generated using the RSA Encryption Algorithm.
when the client wants to send a message, it gets encrypted with the public key, through the server then will forward it to the connected clients, that will decrypt it using the private key.

For more detailed explanation, please, refer to the RSA Encryption Algorithm Documentation
