A valid network key will be a 16 byte value, defined in the zwave section of your configuration, such as the following example:
```
```yaml
zwave:
usb_path: /dev/ttyACM0
network_key: "0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10"
usb_path: /dev/ttyACM0
network_key: "0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F, 0x10"
```
Each individual value in the defined key can be anywhere from 0x00 to 0xFF. Define your own key by making changes to the above example key or for additional security try one of the two scripts mentioned below.

### {% linkable_title Network Key %}
An easy script to generate a random key:
```bash
cat /dev/urandom | tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
$ cat /dev/urandom | tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
```
On macOS, this script will generate a random key:
```bash
cat /dev/urandom | LC_CTYPE=C tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
$ cat /dev/urandom | LC_CTYPE=C tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
```
If the above command doesn't work then replace `LC_CTYPE=C` with `LC_ALL=C`:
```bash
$ cat /dev/urandom | LC_ALL=C tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
```
