# Using the tls module

If your transaction script needs to connect to a server over TCP secured with TLS, use the `tls` module, which is included as a part of the ThousandEyes `net` module.

## Creating a Connection

To create a client connection that includes TLS, use the `connectTls` function:

`await net.connectTls(<port>, '<host.ip.address>', [OPTIONS])`

## Example GET Request with TLS

In the following example, notice that you first set host and port; then use those when you call `net.connectTls`:

```
import { net } from 'thousandeyes';

runScript();

async function runScript() {
   let host = 'google.com';
   let port = 443;
   let request_body = `GET / HTTP/1.1\r\n` +
                   `Host: ${host}\r\n` +
                   `User-Agent: thousandeyes-transaction\r\n` +
                   `\r\n`;

  let client = await net.connectTls(port, host);
  client.setEncoding('utf8');
  await client.write(request_body);
  await client.end();
  let response = await client.read();
  
  console.log(response);

};
```
