Встроенные функции безопасности и аутентификации. Без каких‑либо компромиссов с базами данных или моделями данных.

Все схемы безопасности, определённые в OpenAPI, включая:

* HTTP Basic.
* **OAuth2** (также с **токенами JWT**). Ознакомьтесь с руководством [OAuth2 с JWT](tutorial/security/oauth2-jwt.md).
* Ключи API в:
    * HTTP-заголовках.
    * Параметрах запросов.
    * Cookies и т.п.

   * If a challenge uses the `token68` variant instead of auth params, there is exactly one
   * auth param in the challenge at key null. Invalid headers and challenges are ignored.
   * No semantic validation is done, for example that `Basic` auth must have a `realm`
   * auth param, this is up to the caller that interprets these challenges.

  fun challenges(): List<Challenge> {
    return headers.parseChallenges(

        }

        // Check if consumer POM flattening is disabled
        if (!flattenEnabled) {
            // When flattening is disabled, treat non-POM projects like parent POMs
            // Apply only basic transformations without flattening dependency management
            // However, BOMs still need special handling to transform packaging from "bom" to "pom"
            if (isBom) {

For disabling entire types of tests for subprojects, one can use for example:

------------------------------------------------
if (BuildParams.inFipsJvm){
  // This test cluster is using a BASIC license and FIPS 140 mode is not supported in BASIC
  tasks.named("javaRestTest").configure{enabled = false }
}
------------------------------------------------

in `build.gradle`.

=== Limitations

- **Concurrent Utilities** (`org.codelibs.core.concurrent`) - Thread-safe collections and concurrency helpers using modern concurrent APIs
- **Crypto & Security** (`org.codelibs.core.crypto`, `org.codelibs.core.security`) - Basic cryptographic utilities, message digest operations, and secure random generation
- **XML Processing** (`org.codelibs.core.xml`) - XML DOM utilities, SAX parser helpers, and schema validation support

            public int getDayForCleanup() {
                return 3;
            }
        };
        ComponentUtil.register(fessConfig, FessConfig.class.getCanonicalName());
    }

    // Test basic configuration properties
    @Test
    public void test_domainTitle() {
        assertEquals("Fess", fessConfig.getDomainTitle());
    }

# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md).

## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

        // The third parameter is the size of the output string in characters
        // size = number of hex characters to output
        // Each byte produces 2 hex characters

        // Test basic conversion (srcIndex is ignored in the implementation)
        byte[] data1 = { 0x00, 0x01, 0x02, 0x03 };
        assertEquals("00", Hexdump.toHexString(data1, 0, 2)); // 2 chars = 1 byte

Sicherheit und Authentifizierung sind integriert. Ohne Kompromisse bei Datenbanken oder Datenmodellen.

Alle in OpenAPI definierten Sicherheitsschemas, inklusive:

* HTTP Basic.
* **OAuth2** (auch mit **JWT Tokens**). Siehe dazu das Tutorial zu [OAuth2 mit JWT](tutorial/security/oauth2-jwt.md).
* API Schlüssel in:
    * Headern.
    * Query-Parametern.
    * Cookies, usw.

            return encodeCallCount;
        }

        public byte[] getData() {
            return data;
        }
    }

    /**
     * Mock implementation for basic interface testing
     */
    static class MockCreateContextRequest implements CreateContextRequest {
        private final byte[] name;
        private final int size;
