## Utilidades de **FastAPI**

FastAPI proporciona varias herramientas para cada uno de estos esquemas de seguridad en el módulo `fastapi.security` que simplifican el uso de estos mecanismos de seguridad.

En los siguientes capítulos verás cómo agregar seguridad a tu API usando esas herramientas proporcionadas por **FastAPI**.

     * Any change to the extended attributes (EA) of a file in the watched directory or subtree causes a change notification wait operation to return.
     */
    int FILE_NOTIFY_CHANGE_EA = 0x00000080;

    /**
     * Any security-descriptor change in the watched directory or subtree causes a change notification wait operation to
     * return.
     */
    int FILE_NOTIFY_CHANGE_SECURITY = 0x00000100;

## Преимущества **FastAPI**

Fast API предоставляет несколько инструментов для каждой из этих схем безопасности в модуле `fastapi.security`, которые упрощают использование этих механизмов безопасности.

В следующих главах вы увидите, как обезопасить свой API, используя инструменты, предоставляемые **FastAPI**.

### Sécurité et authentification

La sécurité et l'authentification sont intégrées. Sans aucun compromis avec les bases de données ou les modèles de données.

Tous les protocoles de sécurités sont définis dans OpenAPI, incluant:

* HTTP Basic.
* **OAuth2** (aussi avec **JWT tokens**). Jetez un oeil au tutoriel [OAuth2 avec JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.

            buf.setIndex(0);
            this.securityProvider.wrap(buf);
        }
        return buf;
    }

    /**
     * Sets the DCERPC security provider for authentication and message protection
     * @param securityProvider the security provider to use for DCERPC authentication
     */
    public void setDcerpcSecurityProvider(final DcerpcSecurityProvider securityProvider) {

 * when it encounters surrogate pairs. This class facilitates the correct escaping of all Unicode
 * characters.
 *
 * <p>As there are important reasons, including potential security issues, to handle Unicode
 * correctly if you are considering implementing a new escaper you should favor using UnicodeEscaper
 * wherever possible.
