#### 3.3.1 Install and configure GnuTLS

Download and decompress the Windows version of GnuTLS from [here](http://www.gnutls.org/download.html).

Use PowerShell to add the path of the extracted GnuTLS binary to the system path:

```
setx path "%path%;C:\Users\MyUser\Downloads\gnutls-3.4.9-w64\bin"
```

**Note:** PowerShell may need to be restarted for this change to take effect.

#### 3.3.2 Generate a private key
