# Field Level Encryption

To do this, adjust the config.json as follows:

1. Add the corresponding configuration under `"database"`:

```
  "database": {
    "uriConnectionString": "mongodb//...",
    "fieldLevelEncryption": {
      "enabled": true,
      "key": "..."
    }
  },
```

{% hint style="info" %}
Please leave space between the quotation marks for a secure password with 16 to 32 characters for "key": "...".
{% endhint %}

2. You must run setup.sh after every customization!

{% hint style="danger" %}
3\) Finally, save your key carefully.
{% endhint %}
