### Custom Settings ### Custom Settings
You may want to select other channels for your usage. The other settings can be set by using the Python API. Custom settings can be applied by using [supported software](/docs/software).
```shell
meshtastic --ch-set spread_factor 10 --ch-set coding_rate 4 --ch-set bandwidth 125 --ch-index 0
```
After applying the settings, you will need to restart the device. After your device is restarted, it will generate a new crypto key and you will need to share the newly generated QR Code or URL to all your other devices.

## Cryptography ## Cryptography
The pre-shared key (PSK) used by the devices can be modified. The pre-shared key (PSK) used by the devices can be an AES128 or AES256 sequence. Alternatively, encryption can be turned off, which may be useful if you are operating under a Ham Radio license.
- 0 = No crypto
- 1 = Default channel key
- 2 - 10 = The default channel key, except with 1 through 9 added to the last byte
Use of cryptography can also be modified. To disable cryptography (maybe useful if you have Ham radio license):
```shell
meshtastic --setchan psk 0
```
