 The following [extra features](https://packaging.python.org/en/latest/specifications/dependency-specifiers/#extras) are available for the Singer SDK:
 
+- `crypto` - Enables the `OAuthJWTAuthenticator` class for JWT (JSON Web Token) authentication.
 - `faker` - Enables the use of [Faker](https://faker.readthedocs.io/en/master/) in [stream maps](stream_maps.md).
 - `s3` - Enables AWS S3 as a [BATCH storage](batch.md#the-batch-message).
