# Integer Key Generates unique integer values. By default, the generated values are within the range of the column’s data type. You can also specify a range for the generated values. The source values must be within that range. This generator cannot be used to transform negative numbers. ## Characteristics


Consistency	Yes, can be made self-consistent.
Linking	No, cannot be linked.
Differential privacy	Yes, if consistency is not enabled.
Data-free	Yes, if consistency is not enabled.
Allowed for primary keys	Yes
Allowed for unique columns	Yes
Uses format-preserving encryption (FPE)	Yes
Privacy ranking	1 if not consistent 4 if consistent
Generator ID (for the API)	`IntegerPkGenerator`

## How to configure To configure the generator: 1. In the **Minimum** field, enter the minimum value to use for an output value.\ \ The minimum value cannot be larger than any of the values in the source data. 2. In the **Maximum** field, enter the maximum value to use for an output value.\ \ The maximum value cannot be smaller than any of the values in the source data. 3. Toggle the **Consistency** setting to indicate whether to make the column self-consistent.\ \ By default, consistency is disabled. 4. If [Structural data encryption](/app/generation/generators-assign-config/generators-data-encryption-config.md) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
