## How to configure <a href="#random-double-configure" id="random-double-configure"></a>

To configure the generator:

1. In the **Minimum** field, type the minimum value to use in the output values.\
   \
   The minimum value is inclusive. The output values can be that value or higher.
2. In the **Maximum** field, type the maximum value to use in the output values.\
   \
   The maximum value is exclusive. The output values are lower than that value.
3. If [Structural data encryption](https://docs.tonic.ai/app/generation/generators-assign-config/generators-data-encryption-config) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position.
