// This is a simplified HMAC-MD5 calculation for comparison, not a full RFC 2104 implementation.
        // The HMACT64 implementation is what we are testing.
        MessageDigest md5 = MessageDigest.getInstance("MD5");

This makes it easy to generate up-to-date **documentation**, client libraries (<abbr title="Software Development Kits">**SDKs**</abbr>) in multiple languages, and **testing** or **automation workflows** that stay in sync with your code.

In this guide, you'll learn how to generate a **TypeScript SDK** for your FastAPI backend.

## Open Source SDK Generators { #open-source-sdk-generators }

Затем мы можем запросить ее в *функции-обработчике пути* как зависимость и использовать там, где нужно.

{* ../../docs_src/settings/app02_an_py310/main.py hl[17,19:21] *}

### Настройки и тестирование { #settings-and-testing }

Далее будет очень просто предоставить другой объект настроек во время тестирования, создав переопределение зависимости для `get_settings`:

{* ../../docs_src/settings/app02_an_py310/test_main.py hl[9:10,13,21] *}

Compiling models via the recommended entry points described in
[XLA](https://www.tensorflow.org/xla) and
[JAX](https://jax.readthedocs.io/en/latest/jax-101/02-jitting.html)
documentation should be safe, while some of the testing and debugging tools that
come with the compiler are not designed to be used with untrusted data and
should be used with caution when working with untrusted models.
