## Configuring and starting the server

#### Configuration
The first thing you need to do is to generate a RSA Keypair so that you can have secure communication between the client
and the server. To do so, run `com.github.thetya.server.tools.RsaKeypairGenerator`. You do not need to pass any arguments.
When it's done, you will either see the keys in the console or have them generated in a `keys.txt` file.

Copy the private key and open up `rsrc/server.properties`. Find `key.private` and paste it.

You will need to determine your local IPv4 address. On Windows:

Put this into `rsrc/server.properties` under the field `hostname.bind`. You can now close the file.

Now open Spiral Knights client directory, go to `code/`, unzip `config.jar` and extract `deployment.properties`. Open it.
Set `server_host` to the value you pasted into server config before, `server_ports` to `47624`, `datagram_ports` to
`47625` and `key.public` to the public key you should have generated in the first step. Save the file and replace it in the
jar.

---

Now we need to set up the database. Open `rsrc/server.properties`, scroll to the bottom. You need to create 3 databases
and fill out the credentials using which they can be operated. The tables and schema migrations will be handled
automatically.

#### Starting the server
Just run `com.github.thetya.server.ThetyaServer`.

#### Creating a user
Make sure you have database credentials typed in into server config. Use:

```
$ com.github.thetya.server.tools.UserTool create [username] [password] [email]
```

The password will be hashed for you and a new account will be created. `siteId` will be set to `204` as this is the ID
for Spiral Knights.
