# Generator reference This generator reference provides the details for each of the the supported generators in Tonic Structural.
Information provided for each generator For each generator, the reference provides: * Overview description * A table that contains: * Generator characteristics that you might want to take into account when you select the generator. * The generator [privacy ranking](https://docs.tonic.ai/app/privacy-report#privacy-report-privacy-ranking-about), which indicates the level of protection that the generator provides. * The generator ID to use in the Structural API. The generator ID is linked to the API details for the generator. * Instructions for how to configure the generator The generator characteristics include: * [Consistency](https://docs.tonic.ai/app/generation/generators/generator-characteristics/consistency) - Whether you configure the generator to base the the destination values on the source values. * [Linking](https://docs.tonic.ai/app/generation/generators/generator-characteristics/linking-generators) - Whether you can link columns that use the generator to indicate that there is a relationship between them. * [Differential privacy](https://docs.tonic.ai/app/generation/generators/generator-characteristics/differential-privacy) - Whether the generator supports differential privacy, which ensures that the source value cannot be reverse engineered from the output value. * [Data-free](https://docs.tonic.ai/app/generation/generators/generator-characteristics/data-free-generators) - Whether the generator is data-free, meaning that the output data is completely unrelated to the source data. * [Allowed for primary keys](https://docs.tonic.ai/app/generation/generators/generator-types/primary-key-generators) - Whether you can assign the generator to primary key columns. * [Allowed for unique columns](https://docs.tonic.ai/app/generation/generators/generator-characteristics/generators-uniqueness-constraints) - Whether you can assign the generator to columns that require unique values. * [Uses format-preserving encryption (FPE)](https://docs.tonic.ai/app/generation/generators/generator-characteristics/generators-fpe) - Whether the generator uses FPE to encrypt the values.
The generators are in alphabetical order by the generator name. Here are some groupings to help to identify generators that are used for different types of values. [common-usage](https://docs.tonic.ai/app/generation/generators-assign-config/common-usage "mention") also provides some suggestions for generators to use for specific uses cases.
